First record of a fossil selenariid bryozoan in South America

López-Gappa, J., Pérez, L.M. & Griffin, M. February 2017. First record of a fossil selenariid bryozoan in South America. Alcheringa XX, xxx-xxx. ISSN 0311-5518.

Selenariidae Busk 1854 (Bryozoa) is considered endemic to Australia and New Zealand. Here we describe a new species of Selenaria Busk 1854 from the lower Miocene Monte León Formation (Patagonia, Argentina). Selenaria lyrulata sp. nov. is characterized by autozooids with a lyrula-like, anvil-shaped cryptocystal denticle, opesiular indentations and lateral condyles, as well as avicularia with a shield of fused costae. This is the first record of a selenariid bryozoan in South America.

Writing on the edge: the poet,the printer,and the colonial frontier in Ercilla’s La Araucana (1569–1590)

It took Alonso de Ercilla (1533–1594) thirty years to finish La Araucana, a first-person narrative epic poem about the brutal war of Arauco, in southern Chile, and one of the most canonical texts of colonial Latin America. By focusing on a crucial episode of Ercilla's eyewitness account, this essay revisits a number of scholarly discussions that have been central for our understanding of the text. First, it takes into consideration previous scholarship overlooked by specialists, as well as hitherto unstudied copies of the poem, in order to offer a thorough reevaluation of the textual and editorial history of the poem. Moreover, it explores the frontier as a chronotope and as a locus of enunciation for colonial epic, a space that is also crucial for Ercilla's carefully crafted authorial persona. Finally, it interrogates the ways in which the discursive representations of colonial frontier spaces were mediated by the material practices of early modern book production, arguing for a more fruitful relation between ecdotics and poetics, between material bibliography and theories of authorship and textuality in our approaches to colonial texts.     

EMPIRICAL STUDIES IN INDUSTRIAL LOCATION: AN ASSESSMENT OF THEIR METHODS AND RESULTS*

ABSTRACT This paper surveys recent evidence on the determinants of (national and/or foreign) industrial location. We find that the basic analytical framework has remained essentially unaltered since the early contributions of the early 1980s while, in contrast, there have been advances in the quality of the data (more firm and plant level information, geographical disaggregation, panel structure, etc.) and, to a lesser extent, the econometric modeling. We also identify certain determinants (neoclassical and institutional factors) that tend to provide largely consistent results across the reviewed studies. In light of this evidence, we finally suggest future lines of research.     

Sprawl in Spain and Madrid: A Low Starting Point Growing Fast

This article comments upon the situation of sprawl in Spain and Madrid, especially residential sprawl. It does not appear to be a serious problem due to its low starting point, but artificial surface and residential sprawl is growing rapidly. For that reason, it may be an issue in the future. Between 2000 and 2006, urban residential land use grew 0.4% in Spain and 0.2% in Europe per year, land use of industrial and commercial areas grew 2.3% in Spain and 0.4% in Europe and total artificial surface grew 2.7% in Spain and 0.6% in Europe (EEA, 2010). Further, we will study the legislation on maximum and minimum urban density in Spain. The highest maximum urban density is established by the Basque Country, with 230 dwellings per hectare, and the highest minimum urban density is established by Catalonia, with 50 dwellings per hectare. In both cases, it is applied to only certain types of territories. Finally, we will analyse what happens in the Region of Madrid in relation to sprawl. It has very similar patterns compared with the rest of Spain, although more pronounced.     

Barrio resurgence in Buenos Aires: Local autonomy claims amid state-sponsored transnationalism

This paper argues that observing neighborhood movements through the lens of territorial state restructuring holds theoretical promise. Contemporary struggles over municipal decentralization need to be located within broader state re-scaling processes. Seeking to contribute a Latin American perspective to the largely Anglo-American field of urban neoliberalization research, this study engages with the emergence of local autonomy claims in Buenos Aires, Argentina. Middle-class activists and organizations advanced such claims against the background of thorough transnationalism, in what may be interpreted as a localist political reaction to the socio-spatial consequences of urban and state restructuring. Field evidence is used to assess the ultimate political efficacy and democratic implications of their political agency, particularly in what concerns municipal decentralization. It is argued that curtailing the empowerment of barrio districts were the following conditions: mayoral opposition to communal reforms; ongoing cross-scalar tensions between the city and national government; and the barrio-centric issue framings of activists, which hampered social recruitment in an increasingly heterogeneous and transnationalized urban space.
