A City at Play: Rio de Janeiro on the Eve of the 2016 Olympic and Paralympic Games

What will be the outcome of the large-scale construction programmes and under-delivered promises undertaken in preparation for the 2016 Olympic and Paralympic Games? Ana Luiza Nobre , Associate Professor of Architectural History at the Pontifical Catholic University of Rio de Janeiro and Head of Research and Education at the Instituto Moreira Salles, gazes into her crystal ball and asks what the ongoing legacy of Rio 2016 might be.     

Recife: The Popular Struggle for a Better City

Sometimes dubbed Brazil's Venice, Recife is situated on a series of islands, articulated by waterways, on the country's northeast coast. The nation's ninth largest city, it has a historical core, but also shares many urban challenges common to other Brazilian metropolises: a beachfront blighted by speculative development, a semi-derelict port area and extensive zones of poor neighbourhoods. Architects and academics Circe Monteiro and Luiz Carvalho from the multidisciplinary research group INCITI (Research and Innovation for Cities) at the Federal University of Pernambuco, Recife, describe here why, despite a history of inconsistent development, this could now be Recife's moment to transform itself as the urban agenda comes to the fore.     

Applying SRTM digital elevation model to unravel Quaternary drainage in forested areas of Northeastern Amazonia

There has been an increasing number of articles stressing the advantage of applying remote sensing products of synthetic aperture radar (SAR) and interferometric synthetic aperture radar (InSAR) for rapidly enhancing the volume of geological data in Amazonian areas, where forest cover is dense and high, clouds are abundant and accessibility is limited. The majority of these studies has emphasized geomorphology as a tool for both discussing tectonic reactivations during the Cenozoic and reconstructing Quaternary paleolandscapes. This work applies Digital Elevation Model (DEM) derived from the Shuttle Radar Topography Mission (SRTM) for delineating past morphological features under dense rainforest in an Amazonian lowland area. Previous use of this tool in southwestern Marajó Island (northern Brazil) helped to delineate, with exceptional precision, a paleochannel network hidden under the rainforest, which would be barely detected with other available remote sensing products. Fieldwork revealed that these paleochannels are related to palimpsest drainage systems developed mostly during the last 40,000 ¹⁴C yr B.P. Measured altitudes acquired during topographic surveys attested that paleochannel areas are slightly higher than adjacent floodplains. This fact determined the successful application of SRTM–DEM for mapping paleochannels in Marajó Island. Integration of SRTM data with sedimentological information collected during fieldwork suggests paleoflows derived from continental areas located to south of the study area. This paleodrainage was active when the island was still connected to mainland. With island detachment due to reactivation of tectonic faults, the channels became abandoned and were progressively forested. The results obtained in the present study indicate that SRTM–DEM has high potential for unraveling similar morphological features from many other Amazonian areas with low topography and a dense forest cover.

Assigned versus participative goal setting with educated and uneducated woods workers.

Conducted a field experiment of (a) 24 educationally disadvantaged woods worker crews and (b) 24 educated logging crews to compare assigned goal setting, participative goal setting, and a "do your best" condition. The experiment was conducted separately for each sample. Results show that for the uneducated Ss, the participative condition had higher productivity than the assigned and "do your best" conditions. In addition, goal difficulty and goal attainment were significantly higher in the participative condition than in the assigned condition. No significant differences among conditions were found for the educated Ss, although this may have been due to problems in implementation of the goal-setting program with this sample.

Effects of assigned versus participatively set goals, knowledge of results, and individual differences on employee behavior when goal difficulty is held constant.

In Exp I, 60 female clerical workers were randomly assigned to participative, assigned, and "do best" goal conditions on a clerical test. Specific goals led to higher performance than did the "do best" goals. With goal difficulty held constant, there was no significant difference between the assigned and participative conditions on performance or goal acceptance. Goal attainment, however, was higher in the assigned condition than it was in the participative condition. No main or interaction effects were found for knowledge of results (KR) or for individual difference measures with performance or goal acceptance. However, high self-esteem Ss who received KR attained their goals more often than did Ss with low self-esteem when the goals were participatively set. Exp II was conducted with 28 employees from the same sample in a performance-appraisal setting over an 8-mo period. Assigned goals resulted in higher performance and greater goal acceptance than participatively set goals. There was a positive linear relationship between goal difficulty and performance in the participative condition only. (10 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)
