The Constellation: A Reappraisal of Walter Benjamin's Influence on Theodor W. Adorno

open access: yesConstellations, EarlyView.
ABSTRACT In the 1920s and 1930s, Walter Benjamin and Theodor W. Adorno both sought to develop a notion of Darstellung—of philosophical presentation or representation—that could provide an alternative to the classically idealist tendency to subsume objects under abstract concepts.

The Political Ecology of the ‘New’ Feminism in Late‐1990s Britain

open access: yesGender &History, EarlyView.
ABSTRACT The 1990s were a vexed time for feminists in Britain. Cultural commentators declared that feminism's key battles had been won, and that given women's ascendency across various political and cultural barometers of success, the country was entering a newly ‘postfeminist’ era.

Effect of Cross-Linking on the Electrical Properties of LDPE and its Lightning Impulse Ageing Characteristics

open access: yes, 2011
Cross-linked polyethylene (XLPE) is commonly used within high voltage cable insulation. It has improved thermal and mechanical resistance compared to normal low density polyethylene (LDPE).

Barbara's Daughters: Women's Boxing and Social Memory in Britain

open access: yesHistory, EarlyView.
Abstract A pioneer of post‐war boxing, Barbara Buttrick fought in fairgrounds and on music‐hall stages in Britain and France before making a career in the United States during the 1950s. She fought against practical obstacles, prejudice and discrimination to become the Women's World Flyweight and Bantamweight Champion in 1957. This article examines her

TERRITORIAL VALORIZATION: How Positive Stereotypes Advance Suburban Water Insecurity in Detroit

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract Suburbs historically enabled and protected white middle‐class wealth in the United States; however, their more recent diversification has included a rise in suburban poverty. This article examines these dynamics through the issue of household water access—a feature of rising suburban impoverishment that deserves greater attention.

Can Enterprises Invest Efficiently in Smart Cities?

open access: yesAccounting &Finance, EarlyView.
ABSTRACT The rapid expansion of the digital economy has accelerated smart city (SC) development in China. Using a time‐varying difference‐in‐differences approach, we examine the impact of SC policies on corporate investment efficiency. We document that SC construction significantly enhances investment efficiency, with robust results across multiple ...

Influence of the Residual Inductance of the Impulse Generator for the Generation of the Lightning Impulse Voltage

open access: yesIEEJ Transactions on Power and Energy, 2007
This paper describes the theoretical analysis of lightning impulse voltage waveform with an overshoot or oscillation caused by the residual inductance of the impulse generator. The oscillating lightning impulse waveform is expressed by the following formula;vout (t) = A {e-α1t - e-α2t sin(ωt+θ)/sinθ}where A, α1, α2, ω, θ are constants, respectively ...
