Twenty-five years of two-dimensional rational conformal field theory

In this article we try to give a condensed panoramic view of the development of two-dimensional rational conformal field theory in the last twenty-five years.Comment: A review for the 50th anniversary of the Journal of Mathematical Physics. Some references added, typos correcte

Editorial: toward 50 years of 'Water Resources Research'

The first issue of 'Water Resources Research' (WRR) was published in March 1965 and, therefore, the year 2015 will present the exciting opportunity to celebrate the 50th anniversary of the journal. Naturally, this milestone will be seen as an occasion to look back on 50 years of research activity. The history of WRR provides a very interesting perspective on the development of hydrology and the legacy of the worldwide water resources community

Composing in the Discomfort of Institutional Violence

This short piece reflects on the 50th anniversary of the journal Composition Studies, discussing the need for more scholarship on Critical Race Theory (CRT) in the journal. This piece holds up an article by Aja Martinez on CRT in Composition Studies as an example of the work that the journal and field need to continue to engage with, especially in light of the events of 2020 and the Black Lives Matter movement

Introduction: global challenges for sociology

With the 50th anniversary of the journal, this special issue takes stock of the progress that has been made within sociology to become a more globally oriented discipline and discusses the new challenges for the future that emerge as a consequence. From its inception, classical sociology was primarily concerned with the European origins of processes of modernity that were to become global. There was little discussion of how the global might be understood in terms of structures, processes and social movements not directly identified as European but nonetheless contributing to modernity. The challenge for sociology has been to take into account these other phenomena and to rethink its core categories and concepts in light of newly understood alternative formations of the global and the social movements that bring them about

Metallic muscles and beyond:nanofoams at work

In this contribution for the Golden Jubilee issue commemorating the 50th anniversary of the Journal of Materials Science, we will discuss the challenges and opportunities of nanoporous metals and their composites as novel energy conversion materials. In particular, we will concentrate on electrical-to-mechanical energy conversion using nanoporous metal-polymer composite materials. A materials system that mimic the properties of human skeletal muscles upon an outside stimulus is coined an 'artificial muscle.' In contrast to piezoceramics, nanoporous metallic materials offer a unique combination of low operating voltages, relatively large strain amplitudes, high stiffness, and strength. Here we will discuss smart materials where large macroscopic strain amplitudes up to 10 % and strain-rates up to 10(-2) s(-1) can be achieved in nanoporous metal/polymer composite. These strain amplitudes and strain-rates are roughly 2 and 5 orders of magnitude larger than those achieved in common actuator materials, respectively. Continuing on the theme of energy-related applications, in the summary and outlook, we discuss two recent developments toward the integration of nanoporous metals into energy conversion and storage systems. We specifically focus on the exciting potential of nanoporous metals as anodes for high-performance water electrolyzers and in next-generation lithium-ion batteries

Contemplating and Extending the Scholarship on Children’s and Young Adult Literature

To commemorate the 50th anniversary of the Journal of Literacy Research, this article reviews the trajectory of a particular line of scholarship published in this journal over the past five decades. We focus on African diaspora youth literature to contemplate and extend the ways in which literacy researchers carry out textual analysis research of diverse children’s and young adult literature. We situate this line of scholarship (and its trajectory) within the broader literacy field and then narrow to a focus on diverse books. Next, to turn our gaze as literacy researchers forward to the future, we present our own critical content analysis of a young adult text collection. Our analysis incorporates postcolonial theory and a youth lens to interrogate how underlying ideologies identified within the novels support, refute, or reconstruct dominant beliefs about Black girls. We end with a set of implications for researchers interested in theorizing about or further investigating diverse children’s or young adult literature
