Size distribution, sex ratio and use of burrows of the burrowing toad Rhinella fernandezae were studied in Buenos Aires province, Argentina. Two sites separated by approximately 300 m were studied: one was a road next to a swamp, and the other a garden of a country house located further from the swamp. We identified toad burrows, and individuals were sexed, measured and given an individual mark. Burrows were examined in subsequent months after the first sampling to assess the presence of toads. We found significant differences in the size distribution between areas, being the proportion of juveniles greater at the site next to the swamp where the reproduction of the species was observed. This result may suggest that the site located near to the swamp functions as a source habitat of individuals that migrate to the other site, where recruitment would be very scarce. Sex proportion of adults did not differ from 1:1 in neither the total population nor in each site, suggesting that there was not differential mortality by sex. Some toads changed burrows throughout the study period, but there were not differences in the frequency of change between adults and juveniles.

This article examines the records of mental incompetence cases filed at a court of the first instance in Buenos Aires Province, Argentina. Using a Critical Discourse Analysis framework and qualitative methods, we explore the ways in which mental health sufferers are represented. Applying Tone Theory and Appraisal Theory (attitude/judgement subsystem) to our data, we distinguish two discursive zones. In one of them, subjects are constructed with linguistic resources that amount to inscribed expressions of negative social judgement on their capacity. A discursive dichotomy is created whereby people are either competent or incompetent. In the other zone, these negative dichotomous judgements are largely softened by explicitly positive ones, without disappearing altogether. We suggest that mental incompetence, far from being a dichotomous concept, might be gradual.

The following article is based on a qualitative research developed in three Buenos Aires City and Buenos Aires Province high-schools that define themselves “elite educational institutions”.  Our purpose is to analyze the pedagogical work conducted by these institutions in relation to how they monitor their students’ trajectories and its examination systems. On the one hand, we identify strategies of personalization that account for an institutional set-up with close links between teachers and students, which enables them to overcome the hurdles to a system based on international exams. On the other, strategies of autonomy devolve to students’ responsibility for their own results, encouraging them to compete amongst themselves. These differences are connected to the academic selection systems established by each of the institutions. By inquiring into these dynamics, we have a better understanding of how these institutions function and how they contribute to the processes of socialization and reproduction of specific segments aimed at occupying elite positions. This paper also addresses the role played by the teachers as symbolic facilitators who, through their work, contribute to the selection of those groups.

The Relationship

During the post-Independence period, Buenos Aires province engaged in a republican-authoritarian experiment in which the relations between dominant and subaltern were altered and redefined. The ascent to power of Juan Manuel de Rosas and the federalists meant an increase in the violence meted out by the state against its political and military opponents. On the other hand, the diffusion of a market economy created the basis of contractual relations across a variety of social fields and institutions. This was true with regard to relations between masters and servants in the household, between officers and soldiers within regiments, between rural residents and justices of the peace, between ranchers and peons at the estancia. Though coercion did not disappear, the power to coerce found limits because of the very expansion of market relations. To address these changes, in their complexity and diversity, this article uses the concept “repertoires of coercion”. The concept may be useful to analyze and compare relations of power in multiple social or institutional spaces. In addition, the article addresses the question of the relationship between coercion and market culture, suggesting that in a situation of labor scarcity, and the military mobilization of the subaltern classes, contractualism tends to pervade relations of power, even those previously based upon coercion.

The populations of Buccinanops monilifer (Gastropoda: Nassariidae) from two different sites, Mar del Plata (Buenos Aires province) and a close non-polluted locality (Mar Chiquita), are compared in their imposex indices and reproductive parameters. In Mar del Plata, a beach nourishment (sand filling) remobilized sediment from the harbour area during 1999; our results show high imposex percentage and an increase in relative penis size index during and after this beach filling event, in contrast with the Mar Chiquita population that showed nil values during this study. Comparisons of reproductive parameters between both populations showed significantly higher frequency of spawning females and number of egg capsules per female in Mar Chiquita, while female size and number of eggs per capsule did not differ. Females from Mar del Plata that did not succeed in spawning showed higher imposex values than spawning ones. Sex-ratio was not significantly different from 1:1 in any of the sites (although male-biased in Mar del Plata and the opposite in Mar Chiquita). We found no malformations or abnormalities during intracapsular development in the imposexed population. Alternatively, we found evidence that suggests that B. monilifer intracapsular development includes the occurrence of intracapsular embryonic cannibalism of other smaller embryos, which was not previously known in this genus, and that complements adelphophagy (feeding on nurse eggs feeding).

A young, inexperienced governess is charged with the care of Miles and Flora, two small children abandoned by their uncle at his grand country house. She sees the figure of an unknown man on the tower and his face at the window. It is Peter Quint, the master's dissolute valet, and he has come for little Miles. But Peter Quint is dead. Like the other tales collected here – ‘Sir Edmund Orme’, ‘Owen Wingrave’, and ‘The Friends of the Friends’ – ‘The Turn of the Screw’ is to all immediate appearances a ghost story. But are the appearances what they seem? Is what appears to the governess a ghost or a hallucination? Who else sees what she sees? The reader may wonder whether the children are victims of corruption from beyond the grave, or victims of the governess's ‘infernal imagination’, which torments but also entrals her? ‘The Turn of the Screw’ is probably the most famous, certainly the most eerily equivocal, of all ghostly tales. Is it a subtle, self-conscious exploration of the haunted house of Victorian culture, filled with echoes of sexual and social unease? Or is it simply, ‘the most hopelessly evil story that we have ever read’? The texts are those of the New York Edition, with a new Introduction and Notes.

Abstract The aim of this study was to explore through cross-sectional study the variation in the prevalence of parasitic helminths in canine faeces collected from green spaces of Buenos Aires according to the human density (HD) and economic level (EL) in the surroundings. HD and EL were considered as independent variables with three categories each. Twenty public squares (one hectare of surface) were randomly selected for each existing combination of the two independent variables. Ten random samples of fresh canine faeces were obtained in each square and analysed for helminths by the sedimentation and flotation techniques. The prevalence for each of the species was analysed using generalized linear models (GLM). The prevalence was modelled with a binomial error distribution and a logit link function. Helminth eggs were detected in 45 out of the 200 (22.5%) faecal samples collected and in 18 of the 20 green spaces sampled. The species observed were Ancylostoma caninum (13% of samples), Trichuris vulpis (8%) and Toxocara canis (4.5%). The GLM indicated that the prevalence of A. caninum in the slum areas (very high HD and very low EL) was higher than that in the other areas studied. However, the HD seemed to contribute more than the EL to the variations in the prevalence of A. caninum in faecal samples. The GLM showed no differences in the prevalence of the other parasite species for the different levels of the independent variables.

Agriculture is the largest fresh water consuming sector, and maize is the most produced and consumed crop worldwide. The water footprint (WF) methodology quantifies and evaluates the water volumes consumed and polluted by a given crop, as well as its impacts. In this work, we quantified for the first time the green WF (soil water from precipitation that is evapotranspired) and the green virtual water exports of maize from Buenos Aires province, Argentina, during 2016–2017, due to the relevance of this region in the world maize trade. Furthermore, at local level, we quantified the green, blue (evapotranspired irrigation), and grey (volume of water needed to assimilate a pollution load) WF of maize in a pilot basin. The green WF of maize in the province of Buenos Aires ranged between 170 and 730 m3/ton, with the highest values in the south following a pattern of yields. The contribution of this province in terms of green virtual water to the international maize trade reached 2213 hm3/year, allowing some water-scarce nations to ensure water and water-dependent food security and avoid further environmental impacts related to water. At the Napaleofú basin scale, the total WF of rainfed maize was 358 m3/ton (89% green and 11% grey) and 388 m3/ton (58% green, 25% blue, and 17% grey) for the irrigated crop, showing that there is not only a green WF behind the exported maize, but also a Nitrogen-related grey WF.
