Gender and democratic politics: a comparative analysis of consolidation in Argentina and Chile

This article highlights a number of themes useful in the gendered analysis of democratic consolidation in Latin America by means of a comparative analysis of Argentina and Chile. It starts from the assumption that much of the work on democratisation in Latin America – both orthodox and the literature concentrating on women and transitions – produced up until now, has been too voluntaristic in its approach. It argues that what is needed, particularly in the study of democratic consolidation, is an analysis not only of the impact of women and women's organisations on institutions and structures but also of how these institutions and structures can shape and change gender relations and different women's activities. Any gendered analysis of democratic consolidation must begin by examining the terms of transition which, while they can be subject to some renegotiation later, affect the nature of the subsequent system and the space available to different actors. It is argued that a number of characteristics of the post-transition system are significant: first the impact of more arbitrary populist or presidential systems, second the importance of women's organising both inside and outside the state and party systems and third the existence of an institutionalised party system

You still don't understand: why troubled engagements continue between feminists and (critical) IPE

Relatively early in the attempts to gender the discipline of International Relations (IR), it was argued by some feminist scholars that it was easier to raise feminist concerns in International Political Economy (IPE) than in IR. However, it has subsequently proved very difficult to articulate these concerns within mainstream IPE, as ‘the neo-realist and neo-liberal frameworks, with their common focus on state-centric issues of co-operation and conflict and their positivist and rationalistic methodologies, do not lend themselves to investigating gendered structures of inequality …’. In contrast, more overlap has been discerned between feminist perspectives and methodologies and the less influential ‘globalist’ (also known as critical/transdisciplinary or heterodox) approaches to IPE than with the dominant statist approaches. This article takes this position as its starting point and will focus on the relationship between gendered analyses and critical IPE (as it will be known here). It therefore does not engage with the undoubtedly important question of how far it is possible or desirable to have a gendered analysis that is not linked to feminism, as within both feminist and critical approaches to IPE an emancipatory agenda is entirely legitimate and even an integral part of those approaches

Vacuum spacetimes with a spacelike, hypersurface-orthogonal Killing vector: reduced equations in a canonical frame

The Newman-Penrose equations for spacetimes having one spacelike Killing vector are reduced -- in a geometrically defined "canonical frame'' -- to a minimal set, and its differential structure is studied. Expressions for the frame vectors in an arbitrary coordinate basis are given, and coordinate-independent choices of the metric functions are suggested which make the components of the Ricci tensor in the direction of the Killing vector vanish.Comment: 13 pages, no figures, LaTeX, to be published in Class.

Green's function for gravitational waves in FRW spacetimes

A method for calculating the retarded Green's function for the gravitational wave equation in Friedmann-Roberson-Walker spacetimes, within the formalism of linearized Einstein gravity is developed. Hadamard's general solution to Cauchy's problem for second-order, linear partial differential equations is applied to the FRW gravitational wave equation. The retarded Green's function may be calculated for any FRW spacetime, with curved or flat spatial sections, for which the functional form of the Ricci scalar curvature $R$ is known. The retarded Green's function for gravitational waves propagating through a cosmological fluid composed of both radiation and dust is calculated analytically for the first time. It is also shown that for all FRW spacetimes in which the Ricci scalar curvatures does not vanish, $R \neq 0$, the Green's function violates Huygens' principle; the Green's function has support inside the light-cone due to the scatter of gravitational waves off the background curvature.Comment: 9 pages, FERMILAB-Pub-93/189-

Comparative studies on the structure of an upland African stream ecosystem

Upland stream systems have been extensively investigated in Europe, North America and Australasia and many of the central ideas concerning their function are based on these systems. One central paradigm, the river continuum concept is ultimately derived from those North American streams whose catchments remain forested with native vegetation. Streams of the tropics may or may not fit the model. They have been little studied. The Amani Nature Reserve in the East Usambara Mountains of north-eastern Tanzania offers an opportunity to bring these naturally forested systems to the attention of the ecological community. This article describes a comparison made between two lengths of the River Dodwe in this area. The work was carried out by a group of postgraduate students from eighteen European and African countries with advice from five staff members, as part of a course organised by the Tropical Biology Association. Rigorous efforts were made to standardise techniques, in a situation where equipment and laboratory facilities were very basic, through a management structure and deliberate allocation of work to specialists in each area.The article offers a summary of invertebrate communities found in the stream and its biomass. Crabs seem to be the key organism in both sections of the streams
