Planning from below: using feminist participatory methods to increase women's participation in urban planning

Women have been often invisible in urban planning. Col·lectiu Punt 6, a feminist organisation of women architects and urban planners based in Barcelona, Spain, has developed planning techniques and tools to include women both as objects and subjects of urban planning, and as experts of everyday life. The article focuses on the participatory tools that Col·lectiu Punt 6 has developed that can be used in the different stages of planning, from assessing to evaluating planning policies and interventions, as well as tools of women's empowerment with the goal of promoting bottom-up models of planning. Evidence is shown of how, using these tools, planning becomes more inclusive not only of women in their diversity, but also of children, youth, the elderly, as well as people of different race, ethnicity, income, sexual and gender identities, and capacities. Examples from different contexts are provided, from Spain and Latin America.

Population dynamics ofTelenomus fariai (Hymenoptera: Scelionidae), a parasite of Chagas' disease vectors IX. Larval competition and population size regulation under laboratory conditions

Summary A series of experiments were carried out with the endophagous egg parasiteTelenomus fariai on its hostTriatoma phyllosoma pallidipennis to determine the possible role of intraspecific competition by the parasite progeny in population regulation of the parasite. Eight parasite densities (1, 3, 5, 10, 20, 30, 40, and 50 individuals per vial) were used, and the design of sequentially sacrificed replicates applied. Survivorship curves for each density indicated smaller number of progeny per host at higher densities, and the shapes of the curves suggested a relatively early mortality process.Morris' linear regression technique for determining within-generation density-dependence was used, and the results showed that only larval mortality could be identified as density dependent. The same technique applied within the larval stage proved that only mortality of larvae in their second, third, and fourth day of development were responsible for population regulation. The applicability of the technique, as well as the relevance of the results for natural population, is discussed.
