We describe a nilpotent quotient algorithm for a certain type of infinite presentations: the so-called finite L-presentations. We then exhibit finite L-presentations for various interesting groups and report on the application of our nilpotent quotient algorithm to them. As result, we obtain conjectural descriptions of the lower central series structure of various interesting groups including t...

Homogeneous superspaces arising from the general linear supergroup are studied within a Hopf algebraic framework. Spherical functions on homogeneous superspaces are introduced, and the structures of the superalgebras of the spherical functions on classes of homogeneous superspaces are described explicitly.

We introduce the concept of the Grassmann real form of an arbitrary matrix supergroup and of its Lie superalgebra. This new notion includes as special cases the ordinary real forms (considered and classified by Serganova) but it is more general. Indeed, the Grassmann real forms are characterized by certain Lie superal-gebra automorphisms of order four, while the ordinary real forms by those of ...

This study uses a cross-country panel to examine the determinants of corruption, paying particular attention to political institutions that increase accountability. Even though the theoretical literature has stressed the importance of political institutions in determining corruption, the empirical literature is relatively scarce. Our results confirm the role of political institutions in determi...

In 2019, mentions of “oil worker” in Norwegian newspaper coverage climate change more than quadrupled, mostly reflecting a rise politicians vying for the support this critical constituency. This article explores oil worker period 2017–2021, identifying main agents dominant narratives and demonstrating that agency tends to be ascribed rather workers themselves, despite an outpouring “thank-yous”...

Sport is the most universal of cultural pursuits – it is accessible and of interest to all. Traditional Sports and Games (TSG) are as diverse as our cultures. TSG organisations work tirelessly to promote participation in their sports, but also act as custodians of custom, language and history. However, trends in globalisation have led to a convergence of the majority of spectator interest to ju...

As part of its 100th-anniversary celebration, the Pan American Health Organization has named 12 persons as "Public Health Heroes of the Americas" in recognition of their noteworthy contributions to public health in the Region of the Americas. Over the course of this year, the Revista Panamericana de Salud Pública/Pan American Journal of Public Health will be carrying pieces written by or about ...

All Canadian bioethicists need to reflect on the meaning and value of their work, to see more clearly how the ethics of bioethics is being undermined from within. In the case involving Dr Olivieri, the Hospital for Sick Children, the University of Toronto, and Apotex Inc, there were countless opportunities for bioethical heroism. And yet, no bioethics heroes emerged from this case. Much has bee...

Creative excellence in interdisciplinary research, education, and communication demands stamina and openmindedness. Stamina requires renewal, yet few opportunities for self-renewal are built into most systems. And as experts, our openmindedness is often stifled by our own sense of finishedness. This paper sketches out a strategy for sustained renewal and creative excellence: Each person assembl...
