Remembrance as a body of time : dialogues about communication and temporalities in Jo?o Guimar?es Rosa.

Aqui, abordamos a demanda comunicacional de culto ? velocidade/acelera??o do tempo e seu confronto com a ideia de demora/contempla??o. Exemplo desse embate entre pressa e vagar, o conto A Terceira Margem do Rio, de Jo?o Guimar?es Rosa, mostra-se uma metodologia de reflex?o. Por ele, acionamos a lembran?a (um cerne do conto) como a esteira de uma temporalidade ?nica (ou um rio que corre infinitamente), associamos outras figuras midi?ticas e travamos di?logos sobre comunica??o e temporalidades.This paper discusses the communicational demand for the cult of speed/acceleration of time and its confrontation with the idea of delay/contemplation. An example of this conflict between hurry and slowness, the short story A Terceira Margem do Rio, by Jo?o Guimar?es Rosa, represents a methodology for reflection. Through it, we trigger the remembrance (the core of the story) as a unique temporality (or a river that flows endlessly), we associate other media figures, and we engage in dialogues about communication and temporalities

Between Lolita and Lana Del Rey : market fabrications of sexuality in the female body under the notions of gesture, presence and fading.

Neste artigo, trabalhamos a possibilidade de explora??o mercadol?gica do corpo da cantora estadunidense Lana Del Rey por meio da ret?rica da sexualidade. Verificamos tal manifesta??o a partir da an?lise da sexualidade em Lana durante sua apresenta??o em S?o Paulo, no Festival Planeta Terra, em 2013, com vistas a perspectivas metodol?gicas de gesto, presen?a e o que denominamos como esvanecimento entre Del Rey e a personagem Lolita, de Vladimir Nabokov, aura convocada pela artista em seu show. Enxergamos a discursividade em torno da sexualidade como pragm?tica mercantil que organiza os afetos dos sujeitos que com esse corpo se relacionam. Objeto de consumo de uma l?gica cultural do capitalismo tardio, esse corpo vend?vel n?o rompe, entretanto, com um car?ter representativo, sendo indicativo de disputas na cultura pop.In this article, we work the possibility of market exploration of the American singer Lana Del Rey?s body through the rhetoric of sexuality. We perceived this manifestation from the analysis of sexuality in Lana during her presentation in Sao Paulo, in Planeta Terra Festival, in 2013, in view of the methodological perspectives of gesture, presence and what we denominate as fading between Del Rey and Vladimir Nabokov?s Lolita character, an aura summoned by the artist in her show. We see the discursivity around sexuality as a mercantile pragmatics that organizes the subjects? affection to the body with which they relate. Consumption objects of a late capitalism cultural logic, this saleable body does not, however, break with a representative character, being indicative of disputes within pop culture

INFLUENCE OF ECOLOGICAL GROUP COMPOSITION, PLANTATION SPACING AND ARRANGEMENT IN THE RESTORATION OF RIPARIAN FOREST ON RESERVOIR SHORES

This work aimed to assess the effect of spacing, arrangement and ecological group composition of planted seedlings on the restoration process of artificial reservoir shores in southeastern Brazil. The assessments were performed 12 years after the settlement of the experiment in which five mixed stand models were tested. First, a general evaluation of the stand was performed when we surveyed the overstory and understory, seed bank and soil for chemical analysis.Then, the restoration indicators survival of planted trees, basal area and density of the tree community, litter accumulated on the soil and canopy closure index were utilized to compare the plantation models and to assess the influence the experimental factors on these parameters. In the general analysis, we found that the studied stand presents low diversity, poor regeneration, and seed bank dominated mostly by one planted exotic tree species and weeds, which may jeopardize the selfmaintenance of the stand in the future. The factor that most influenced the models was the ecological group composition with the best performance found for models in which both pioneer and non-pioneer groups were used. Probably, the plantation arrangement and spacing did not have greater influence due to both plant mortality and natural regeneration that has developed to this age. Hence, it is not recommended the use of only pioneer species in the implantation of riparian forest and the proportion of 50% pioneers and 50% non-pioneers using as much species as possible is indicated for areas that might present constraints for the natural regeneration.Este trabalho teve como objetivo avaliar o efeito do espa\ue7amento, arranjo e composi\ue7\ue3o de grupos ecol\uf3gicos das mudas plantadas no processo de restaura\ue7\ue3o de margem de reservat\uf3rio artificial no sudeste do Brasil. As avalia\ue7\uf5es foram realizadas 12 anos ap\uf3s a implanta\ue7\ue3o do experimento em que cinco modelos de plantios mistos foram testados. Primeiramente, fez-se uma avali\ue7\ue3o geral do povoamento por meio de levantamentos do estrato arb\uf3reo, regenerante, banco de sementes e de an\ue1lise qu\uedmica e textural do solo. Em seguida, lan\ue7ou-se m\ue3o dos indicadores de recupera\ue7\ue3o sobreviv\ueancia das \ue1rvores plantadas, \ue1rea basal e densidade da comunidade arb\uf3rea, ac\ufamulo de serapilheira sobre o solo e \uedndice de fechamento do dossel para comparar os modelos e checar a influ\ueancia dos fatores experimentais nestes par\ue2metros. Como resultado da an\ue1lise geral, obteve-se que o povoamento encontra-se em situa\ue7\ue3o de baixa diversidade, com regenera\ue7\ue3o deficiente e banco de sementes dominado majoritariamente por uma esp\ue9cie arb\uf3rea ex\uf3tica utilizada no plantio e esp\ue9cies herb\ue1ceas invasoras, o que pode comprometer a automanuten\ue7\ue3o do povoamento no futuro. O fator que mais influenciou os modelos foi a composi\ue7\ue3o de grupos ecol\uf3gicos com os melhores resultados apresentados pelos modelos em que se usaram ambos os grupos das pioneiras e n\ue3o pioneiras. Provavelmente, o arranjo e o espa\ue7amento de plantio n\ue3o tiveram muita influ\ueancia devido \ue0 mortalidade das mudas e \ue0 regenera\ue7\ue3o natural que se desenvolveu at\ue9 esta idade. Assim, recomenda-se que na implanta\ue7\ue3o de povoamentos para reconstitui\ue7\ue3o de matas ciliares n\ue3o sejam utilizadas apenas esp\ue9cies pioneiras e sugere-se que a propor\ue7\ue3o de 50% de esp\ue9cies pioneiras e 50% de n\ue3o pioneiras, com o maior n\ufamero poss\uedvel de esp\ue9cies, seja utilizada em \ue1reas com defici\ueancia da regenera\ue7\ue3o natural

Articles by Latin American Authors in Prestigious Journals Have Fewer Citations

Background: the journal Impact factor (IF) is generally accepted to be a good measurement of the relevance/quality of articles that a journal publishes. in spite of an, apparently, homogenous peer-review process for a given journal, we hypothesize that the country affiliation of authors from developing Latin American (LA) countries affects the IF of a journal detrimentally.Methodology/Principal Findings: Seven prestigious international journals, one multidisciplinary journal and six serving specific branches of science, were examined in terms of their IF in the Web of Science. Two subsets of each journal were then selected to evaluate the influence of author's affiliation on the IF. They comprised contributions (i) with authorship from four Latin American (LA) countries (Argentina, Brazil, Chile and Mexico) and (ii) with authorship from five developed countries (England, France, Germany, Japan and USA). Both subsets were further subdivided into two groups: articles with authorship from one country only and collaborative articles with authorship from other countries. Articles from the five developed countries had IF close to the overall IF of the journals and the influence of collaboration on this value was minor. in the case of LA articles the effect of collaboration (virtually all with developed countries) was significant. the IFs for non-collaborative articles averaged 66% of the overall IF of the journals whereas the articles in collaboration raised the IFs to values close to the overall IF.Conclusion/Significance: the study shows a significantly lower IF in the group of the subsets of non-collaborative LA articles and thus that country affiliation of authors from non-developed LA countries does affect the IF of a journal detrimentally. There are no data to indicate whether the lower IFs of LA articles were due to their inherent inferior quality/relevance or psycho-social trend towards under-citation of articles from these countries. However, further study is required since there are foreseeable consequences of this trend as it may stimulate strategies by editors to turn down articles that tend to be under-cited.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Latin Amer & Caribbean Ctr Hlth Sci Informat, BIREME PAHO WHO, São Paulo, BrazilUniversidade Federal de São Paulo, DIS Dept Informat Med, São Paulo, BrazilUniversidade Federal de São Paulo, DIS Dept Informat Med, São Paulo, BrazilFAPESP: 05/57665-8CNPq: 2006-0919Web of Scienc

Geocoding rural addresses in a community contaminated by PFOA: a comparison of methods

BACKGROUND: Location is often an important component of exposure assessment, and positional errors in geocoding may result in exposure misclassification. In rural areas, successful geocoding to a street address is limited by rural route boxes. Communities have assigned physical street addresses to rural route boxes as part of E911 readdressing projects for improved emergency response. Our study compared automated and E911 methods for recovering and geocoding valid street addresses and assessed the impact of positional errors on exposure classification. METHODS: The current study is a secondary analysis of existing data that included 135 addresses self-reported by participants of a rural community study who were exposed via public drinking water to perfluorooctanoate (PFOA) released from a DuPont facility in Parkersburg, West Virginia. We converted pre-E911 to post-E911 addresses using two methods: automated ZP4 address-correction software with the U.S. Postal Service LACS database and E911 data provided by Wood County, West Virginia. Addresses were geocoded using TeleAtlas, an online commercial service, and ArcView with StreetMap Premium North America NAVTEQ 2008 enhanced street dataset. We calculated positional errors using GPS measurements collected at each address and assessed exposure based on geocoded location in relation to public water pipes. RESULTS: The county E911 data converted 89% of the eligible addresses compared to 35% by ZP4 LACS. ArcView/NAVTEQ geocoded more addresses (n = 130) and with smaller median distance between geocodes and GPS coordinates (39 meters) than TeleAtlas (n = 85, 188 meters). Without E911 address conversion, 25% of the geocodes would have been more than 1000 meters from the true location. Positional errors in TeleAtlas geocoding resulted in exposure misclassification of seven addresses whereas ArcView/NAVTEQ methods did not misclassify any addresses. CONCLUSIONS: Although the study was limited by small numbers, our results suggest that the use of county E911 data in rural areas increases the rate of successful geocoding. Furthermore, positional accuracy of rural addresses in the study area appears to vary by geocoding method. In a large epidemiological study investigating the health effects of PFOA-contaminated public drinking water, this could potentially result in exposure misclassification if addresses are incorrectly geocoded to a street segment not serviced by public water
