O processo de criação e implementação de unidades de conservação e sua influência na gestão local: o estudo de caso da área de proteção ambiental da ilha do Combu, em Belém/PA

Este trabalho é um estudo de caso que procura analisar o processo de criação da APA da ilha do Combu, unidade de conservação estadual da categoria de uso sustentável, localizada no estuário amazônico, na região insular do município de Belém, Estado do Pará. O objetivo do estudo foi demonstrar que aspectos relacionados ao processo de criação da APA da ilha do Combu impedem que a gestão da unidade se consolide. Para contextualização da área, estão disponibilizados os resultados de um levantamento realizado pelo Órgão gestor da unidade, no ano de 2010, com os responsáveis de uma amostra de 100 residências, distribuídas entre as quatro comunidades existentes na ilha. Em 2013 é realizada uma pesquisa de campo, com os mesmos responsáveis, para averiguar o nível de conhecimento dos entrevistados sobre o processo de criação da APA. Também são entrevistadas mais 10 pessoas relacionadas ao processo de criação, implantação e gestão da unidade, para maiores esclarecimentos sobre o tema e para confrontar ou validar os resultados da pesquisa de campo. Por se tratar de um estudo de caráter qualitativo, foram analisados também: a) o planejamento e gestão realizados na unidade; b) a trajetória histórica da política de conservação nacional; e c) a trajetória histórica da política de conservação na região amazônica e no Estado do Pará. Os resultados obtidos pela pesquisa de campo revelam que: a criação da APA da ilha do Combu foi consequencia de uma indicação científica proveniente de estudos desenvolvidos pelo Museu Paraense Emilio Goeldi (MPEG) na década de 1980, sendo posteriormente apropriados pelo antigo Instituto de Desenvolvimento Econômico, Social e Ambiental do Estado do Pará (IDESP) na década de 1990, se constituindo no principal Órgão responsável pela criação da unidade; de que a maior parte dos entrevistados na ilha desconhece a existência da APA da ilha do Combu; que apenas uma pequena parcela dos entrevistados foi informada/consultada sobre o processo de criação da APA; e que essa consulta foi realizada de maneira informal. Parte-se do princípio de que em unidades de conservação de uso sustentável, a participação da população residente é essencial para o sucesso do planejamento e da gestão, ainda que o Órgão gestor não tenha muitos recursos a serem empregados na administração. A partir da análise de todos esses dados reunidos, concluiu-se que o processo de criação da APA da ilha do Combu, por ter acontecido de maneira apartada do conhecimento da população residente, se estabelece como principal entrave à consolidação da gestão da unidade.

Análise documental das imagens fotográficas de romarias no Nordeste do Brasil

A discussion, through a literature review, on the use of photographic documents and Documentary Analysis (DA) for the preservation, description and retrieval of images of pilgrimages in northeastern Brazil, which are archived at the Laboratory of Information Science and Memory (LACIM). The photograph acts as an expression of faith and devotion; it is a witnesses and documents, through images, the records of the day-to-day folk religion in its multiple meanings and situations, linked to the sacred. The DA —as a set of procedures performed after the reading of documents— facilitates the analysed collection location or query through the documentary language. This paper tries to show that the particular form of the information contained in a photographic archive echoes submerged memories of the pilgrims, authenticating a social fact in the country, capturing the sacredness from specific moments of celebration.

Image Re-Ranking Acceleration on GPUs

Huge image collections are becoming available lately. In this scenario, the use of Content-Based Image Retrieval (CBIR) systems has emerged as a promising approach to support image searches. The objective of CBIR systems is to retrieve the most similar images in a collection, given a query image, by taking into account image visual properties such as texture, color, and shape. In these systems, the effectiveness of the retrieval process depends heavily on the accuracy of ranking approaches. Recently, re-ranking approaches have been proposed to improve the effectiveness of CBIR systems by taking into account the relationships among images. The re-ranking approaches consider the relationships among all images in a given dataset. These approaches typically demands a huge amount of computational power, which hampers its use in practical situations. On the other hand, these methods can be massively parallelized. In this paper, we propose to speedup the computation of the RL-Sim algorithm, a recently proposed image re-ranking approach, by using the computational power of Graphics Processing Units (GPU). GPUs are emerging as relatively inexpensive parallel processors that are becoming available on a wide range of computer systems. We address the image re-ranking performance challenges by proposing a parallel solution designed to fit the computational model of GPUs. We conducted an experimental evaluation considering different implementations and devices. Experimental results demonstrate that significant performance gains can be obtained. Our approach achieves speedups of 7x from serial implementation considering the overall algorithm and up to 36x on its core steps.

Helping End-Users “Engineer” Dependable Web Applications

End-user programmers are increasingly relying on web authoring environments to create web applications. Although often consisting primarily of web pages, such applications are increasingly going further, harnessing the content available on the web through “programs” that query other web applications for information to drive other tasks. Unfortunately, errors can be pervasive in web applications, impacting their dependability. This paper reports the results of an exploratory study of end-user web application developers, performed with the aim of exposing prevalent classes of errors. The results suggest that end-users struggle the most with the identification and manipulation of variables when structuring requests to obtain data from other web sites. To address this problem, we present a family of techniques that help end user programmers perform this task, reducing possible sources of error. The techniques focus on simplification and characterization of the data that end-users must analyze while developing their web applications. We report the results of an empirical study in which these techniques are applied to several popular web sites. Our results reveal several potential benefits for end-users who wish to “engineer” dependable web applications.

ENHANCEMENT OF THE FAA’s ON-LINE WILDLIFE AIRCRAFT STRIKE DATABASE WITH AN INTERACTIVE GRAPHICS CAPABILITY

Embry-Riddle Aeronautical University (Prescott, AZ, USA) was awarded a grant from the William J. Hughes FAA Technical Center in October 1999 to develop and maintain a web site dealing with a wide variety of airport safety wildlife concerns. Initially, the web site enabled users to access related topics such as wildlife management (at/near airports), bird identification information, FAA wildlife management guidelines, education, pictures, current news, upcoming meetings and training, available jobs and discussion/forum sections. In April 2001, the web site was augmented with an on-line wildlife strike report (FAA Form 5200-7). Upon submittal on-line, “quick look” email notifications are sent to concerned government personnel. The distribution of these emails varies as to whether there was damage, human injuries/fatalities, and whether feather remains were collected and will be sent to the Smithsonian Institution for identification. In July 2002, a real-time on-line query system was incorporated to allow federal and local government agencies, airport and operator personnel, and USDA and airport wildlife biologists to access this database (which as of June 2005 contains 68,288 researched strike reports added to at a rate of approximately 500 strike reports/month) to formulate strategies to reduce the hazards wildlife present to aviation. To date (June 2005), over 15,000 on-line real-time queries were processed. In June 2004, ERAU was authorized to develop a graphical interface to this on-line query system. Current capabilities include mapping strikes (by species) on the US map, each of the contiguous 48 state maps (with AK and HI being added), and airport diagrams of the major metropolitan airports as well as the next 46 airports with the most reported strikes The latter capability depicts strikes by runway in plan as well as in elevation view. Currently under development is the ability to view time-sequenced strikes on the US map. This extensive graphical interface will give analysts the ability to view strike patterns with a wide variety of variables including species, seasons, migration patterns, etc. on US and state maps and airport diagrams.

SIS: a program to generate draft genome sequence scaffolds for prokaryotes

Background: Decreasing costs of DNA sequencing have made prokaryotic draft genome sequences increasingly common. A contig scaffold is an ordering of contigs in the correct orientation. A scaffold can help genome comparisons and guide gap closure efforts. One popular technique for obtaining contig scaffolds is to map contigs onto a reference genome. However, rearrangements that may exist between the query and reference genomes may result in incorrect scaffolds, if these rearrangements are not taken into account. Large-scale inversions are common rearrangement events in prokaryotic genomes. Even in draft genomes it is possible to detect the presence of inversions given sufficient sequencing coverage and a sufficiently close reference genome. Results: We present a linear-time algorithm that can generate a set of contig scaffolds for a draft genome sequence represented in contigs given a reference genome. The algorithm is aimed at prokaryotic genomes and relies on the presence of matching sequence patterns between the query and reference genomes that can be interpreted as the result of large-scale inversions; we call these patterns inversion signatures. Our algorithm is capable of correctly generating a scaffold if at least one member of every inversion signature pair is present in contigs and no inversion signatures have been overwritten in evolution. The algorithm is also capable of generating scaffolds in the presence of any kind of inversion, even though in this general case there is no guarantee that all scaffolds in the scaffold set will be correct. We compare the performance of SIS, the program that implements the algorithm, to seven other scaffold-generating programs. The results of our tests show that SIS has overall better performance. Conclusions: SIS is a new easy-to-use tool to generate contig scaffolds, available both as stand-alone and as a web server. The good performance of SIS in our tests adds evidence that large-scale inversions are widespread in prokaryotic genomes.

Seeing beyond reading: a survey on visual text analytics

We review recent visualization techniques aimed at supporting tasks that require the analysis of text documents, from approaches targeted at visually summarizing the relevant content of a single document to those aimed at assisting exploratory investigation of whole collections of documents.Techniques are organized considering their target input materialeither single texts or collections of textsand their focus, which may be at displaying content, emphasizing relevant relationships, highlighting the temporal evolution of a document or collection, or helping users to handle results from a query posed to a search engine.We describe the approaches adopted by distinct techniques and briefly review the strategies they employ to obtain meaningful text models, discuss how they extract the information required to produce representative visualizations, the tasks they intend to support and the interaction issues involved, and strengths and limitations. Finally, we show a summary of techniques, highlighting their goals and distinguishing characteristics. We also briefly discuss some open problems and research directions in the fields of visual text mining and text analytics.
