Negotiating In/visibility: The Political Economy of Lesbian Activism and Rights Advocacy

Efforts to address HIV/AIDS have brought new opportunities and resources to LGBT (lesbian, gay, bisexual, transgender) activism in many parts of the developing world. However, increased attention in terms of both political opportunities and economic resources is uneven across the diverse population of LGBT peoples and activists. Lesbian activists have reaped far fewer benefits than their gay men counterparts. Building on existing approaches to movement visibility and invisibility, we posit a ‘political economy of in/visibility’ to analyse lesbian activism in China and Myanmar, where activists face particularly restrictive political and economic conditions. Rather than focus on visibility as a movement pre‐condition, objective or strategy, we examine the sources of in/visibility and their interactions with activists’ agency; in/visibility emerges from political and economic conditions, but is continuously reshaped by activists who negotiate them. We demonstrate that, despite challenges, lesbian activists respond in ways that help advance LGBT rights advocacy broadly, sometimes even with tactics that their more visible gay counterparts avoid. These interactions subsequently influence the conditions that shape in/visibility. Investigating the political economy of in/visibility, therefore, has significant implications for understanding not only lesbian activism, but also LGBT advocacy and collective mobilization, especially under politically and economically restrictive conditions.     

A Synthesis of Aggregation Methods for Multifacility Location Problems: Strategies for Containing Error

When solving a location problem using aggregated units to represent demand, it is well known that the process of aggregation introduces error. Research has focussed on individual components of error, with little work on identifying and controlling total error. We provide a focussed review of some of this literature and suggest a strategy for controlling total error. Consideration of alternative criteria for evaluating aggregation schemes shows that the method selected should be compatible with the objectives of the analyses in which it is used. Experiments are described that show that two different measures of error are related in a nonlinear way to the number of aggregate demand points (q), for any value of the number of facilities (p). We focus on the parameter q/p and show that it is critical for determining the expected severity of the error. Many practical implementations of location algorithms operate within the range of q/p where the rate of change of error with respect to q/p is highest.     

What really goes on in Silicon Valley? Spatial clustering and dispersal in modular production networks

Is the geographic trajectory of capitalism toward spatial clusteringor dispersal? Recent theoretical work in the stream of ‘relational’economic geography includes several dynamic elements that increasethe importance of spatial clustering over time. This paper developsthe concept of ‘modular production networks’ toshow that spatial clustering and dispersal can be compatible,mutually reinforcing trends. Modular production networks encompassnodes of tacit activity linked through the exchange of codifiedinformation to create global-scale production systems. In placeslike Silicon Valley, industry participants rely on the benefitsof proximity to help build and manage global-scale productionnetworks.     

Plant processing strategies and their affect upon starch grain survival when rendering Peltandra virginica (L.) Kunth,Araceae edible

There is a long history of human interaction with plants of the Aroideae subfamily (Araceae). Despite these plants' chemical defenses against animal and vegetal predation, humans have targeted their starchy corms, tubers and rhizomes for dietary purposes. In the Eastern Woodlands of North America, early Europeans described the Native population as utilizing the highly acridic Peltandra virginica (arrow arum) for subsistence needs. In order to render this resource edible, however, the acridic principle first needs to be eliminated. Our study investigates the affect these processing activities have on the integrity of arrow arum starch grains. Findings from this study demonstrate that environmental variables specific to individual processing procedures may be more influential on starch grain survival than simply the temperatures reached during cooking.
