Sustentabilidade dos sistemas agrícolas: uma análise no contexto da agrodiversidade. Um estudo de caso na Amazônia Oriental

O estudo tem como objetivo avaliar o processo de sustentabilidade em sistemas agrícolas, tendo como parâmetros os fluxos energético e econômico dentre seus compartimentos, cuja dinâmica é regida pela agrodiversidade de um ambiente agrário em transição. O trabalho de campo foi realizado no município de Igarapé-Açu, Nordeste do Pará. Inicialmente foi feito um survey em 60 unidades produtivas, seguindo-se da aplicação de questionário em 25 unidades, de uma modelagem sistémica em 11 unidades, subsidiada por um exame de contexto, além das entrevistas com agentes produtivos locais ligados direta ou indiretamente a ramos de interesses agrícolas. O resultado das análises revelou mecanismos que caracterizam as distintas lógicas que orientam os processos ecológicos e económicos no contexto da agrodiversidade local/regional. Os fenômenos que ocorrem no campo energético material não guardam correlação direta com os fenômenos de natureza econômica. Não há nem mesmo analogia, visto que os parâmetros adimensionais divergem em valores e padrão. Do ponto de vista da dinâmica ecológica/energética, a informação de maior relevância foi sobre o grau de dependência dos agricultores aos recursos da natureza, parametrizado através do seu coeficiente de depredação (φd). O modelo criado permite: configurar a dinâmica estrutural desses sistemas, estimar-lhes os respectivos níveis de dependência aos recursos, bem como o tempo e a área necessários à obtenção de equivalentes custos de oportunidade aos processos de produção agrícola, e, por fim, identificar fatores limitantes à transição agrária no Município. Esses parâmetros ecológicos/econômicos, pioneiramente definidos, podem ser considerados como operacionalizadores para o planejamento de um desenvolvimento agrário sustentável.

O texto discute as tensões emergentes nos processos em curso nas áreas remanescentes de quilombos do sudeste paulista, entre a ação coletiva mediada por um movimento social, e reforçada pelo reconhecimento legal de um direito coletivo ao território, e estratégias múltiplas dos agentes locais visando contornar a precariedade de sua condição social e econômica, por meio de uma abordagem etnográfica de redes sociais, entendendo essas tensões como críticas para as políticas sociais cujo objetivo é o desenvolvimento territorial.

Conselheiros tutelares na linha de frente da prevenção do abuso sexual

Sexual violence against girls under the age of eighteen, in the form of sexual abuse has been identified as an endemic phenomenon by public officials in the cities of São Paulo. Among t agents and tutelary councilors, which reveal the size of their work linked to the Social Assistance System, the Health System and the Public Security System, dialoguing with their local agents. However, prevent sexual abuse and exploitation constitutes a greater challenge, consciously or unconsciously. This paper opens a discussion on the urgency of designing social networks to prevent sexual violence, with participation of researchers and university students. It is based on surveys of public officials in the years 2011 to 2013 in five cities of São Paulo, with over 200 thousand inhabitants.

A Tele-Health Communication and Information System for Underserved Children in Rural Areas of Nicaragua

Millennium Development Goals point out the necessity of actively promoting maternal-child health care status, especially in underserved areas. This article details the development actions carried out between 2008 and 2011 in some rural communities of Nicaragua with the aim to provide a low-cost tele-health communication service. The service is managed by the health care center of Cusmapa, which leads the program and maintains a communication link between its health staff and the health brigades of 26 distant communities. Local agents can use the system to report urgent maternal-child health care episodes to be assessed through WiMAX-WiFi voice and data communications attended by two physicians and six nurses located at the health care center. The health and nutritional status of the maternal-child population can be monitored to prevent diseases, subnutrition, and deaths. The action approach assumes the fundamentals of appropriate technology and looks for community- based, sustainable, replicable, and scalable solutions to ensure future deployments according to the strategies of the United Nations.

Multi-agent location system in wireless networks

In this paper we propose a flexible Multi-Agent Architecture together with a methodology for indoor location which allows us to locate any mobile station (MS) such as a Laptop, Smartphone, Tablet or a robotic system in an indoor environment using wireless technology. Our technology is complementary to the GPS location finder as it allows us to locate a mobile system in a specific room on a specific floor using the Wi-Fi networks. The idea is that any MS will have an agent known at a Fuzzy Location Software Agent (FLSA) with a minimum capacity processing at its disposal which collects the power received at different Access Points distributed around the floor and establish its location on a plan of the floor of the building. In order to do so it will have to communicate with the Fuzzy Location Manager Software Agent (FLMSA). The FLMSAs are local agents that form part of the management infrastructure of the Wi-Fi network of the Organization. The FLMSA implements a location estimation methodology divided into three phases (measurement, calibration and estimation) for locating mobile stations (MS). Our solution is a fingerprint-based positioning system that overcomes the problem of the relative effect of doors and walls on signal strength and is independent of the network device manufacturer. In the measurement phase, our system collects received signal strength indicator (RSSI) measurements from multiple access points. In the calibration phase, our system uses these measurements in a normalization process to create a radio map, a database of RSS patterns. Unlike traditional radio map-based methods, our methodology normalizes RSS measurements collected at different locations on a floor. In the third phase, we use Fuzzy Controllers to locate an MS on the plan of the floor of a building. Experimental results demonstrate the accuracy of the proposed method. From these results it is clear that the system is highly likely to be able to locate an MS in a room or adjacent room.

Turismo rural no Rio Grande do Norte: desafios e perspectivas

The Rural Tourism appears as an economic alternative to the agricultural way, having to base itself on the revaluation of the local resources, as well as must be implemented through the local agents, a tourism of communitarian base. In this perspective the present objective work to analyze of that it forms if configures the tourist activity in the agricultural space of the Rio Grande do Norte, which the challenges and perspectives faced for the development of this activity. On the basis of this approach searched to argue on the deep transformations that the rural space comes suffering, with insertions of activities not-agriculturists, alternative for the effect of the economic reorganization, as well as on the public politics come back toward the Rural Tourism and an analysis concerning the activities of Rural Tourism that the Rio Grande do Norte comes developing and as this if it presents. As it arrives in port theoretical, we use the Concept of Territory, according to Saints, this if it makes pertinent in the conflicting analyses of the agricultural space for inside to embody of its conceptual picture the territorial dynamics substantiated by the relations politics, economic, social and cultural, where in them it made possible one better analysis in this process. As methodology bibliographical survey was used, in periodic, digital books, documents and interviews in some governmental spheres. The Great River of the North was evidenced that, signals for the development of the agricultural Tourism, therefore the state if presents with a gamma of potentialities, identified and developed some already being through some projects, however if it makes necessary a bigger involvement of all the spheres, considered basic so that this activity can be consolidated as plus a tourist segment in the RN.

Território hipermediatizado e cidades locativas: o Projeto "Imaterialaveiro" na divulgação do património (i)material de Aveiro

O presente trabalho visa contribuir com a conceção e implementação de uma plataforma web na área do turismo e da cultura, mais especificamente dedicada ao património (i)material, a cidade de Aveiro. A ambição do projeto é apresentar às pessoas que façam o uso do site www.imaterialaveiro.yolasite.com, o que está por trás de determinados aspetos que caracterizam a cidade de Aveiro, em especial o componente cultural, simbólico e histórico que não pode ser visto facilmente. O projeto tem dois grandes objetivos, o primeiro é fazer um levantamento bibliográfico do que já foi escrito sobre os media locativos e território hipermediatizado, tentando identificar definições dadas por autores diferentes, os exemplos trazidos por esses autores acerca destes media locativos num território hipermediatizado e qual o papel cultural desses dois elementos tecnológicos na atualidade. O segundo grande objetivo é a criação de um mapa virtual baseado em geolocalização. O projeto ImaterialAveiro terá como propósito transmitir através de vídeos o patrimônio (i)material da cidade de Aveiro. A escolha destes patrimônios (i)materiais será um grande desafio no trabalho, tendo em vista que a UNESCO, que é o órgão responsável pela identificação deste tipo de patrimônio, ainda não reconheceu nenhum aspeto da cidade de Aveiro como patrimônio imaterial. Logo, a escolha far-seá com a ajuda dos agentes locais, sendo assim, também, um desafio de cidadania participante. O projeto pretende contribuir para a análise dos media locativos e para a reflexão sobre a sua influência na experiência das cidades, além de deixar para a cidade de Aveiro um exemplo de como interagir com a cultura intangível através da geolocalização.

"Os Conflitos ambientais em Portugal (1974-2015): uma breve retrospectiva"

In this chapter, the authors made a survey of the research undertaken by social scientists and their reflections on environmental conflicts in Portugal. In these, a critical discourse has emerged concerning, on the one hand, the weak public environmental awareness, and, on the other, the progressive obliteration of environmental movements and their institutionalization throughout the creation of different environmental groups and the incorporation of the “environment” in legislation and in political discourse. In a brief retrospective, we review several conflicts taking into account different relevant factors: level of mobilization, media attention received, organization, impact, and ideological reference they have had in Portugal since the seventies. We have particularly highlighted the movement against nuclear energy and the construction of dams, the pollution caused by intensive breeding, the expansion of eucalyptus plantations, the conflicts against “wild” forms of mining, the business of toxic waste, the expansion of the economy of the concrete, the installation of landfills, and the defense of the natural heritage. This survey has considered three periods: the 1970s, marked by the emergence and performance of ecological movements of different ideological extraction; the second half of the 1980s, marked by the institutionalization of the environment and the imposition of a new legal framework with impact on environmental policies resulting from the integration into the European Economic Community; and finally, a third period, from the 1990s to present, marked by increasing environmental media coverage, with a particular emphasis on environmental conflicts in a context of an increasing liberalization of economic activities and the expansion of extraction and of the concrete economy. This is also the period where the environment emerges in disputes over the uses of the territory as economic and asset value. Most of these conflicts arise from the activities of local agents or national environmental groups that quickly gain strong local roots and sometimes even have some success. However, their impact on the national and Community legislation seems to be less relevant.

Electrocardiographic Alterations During Endosseous Implant Placement Performed with Local Anesthetic Agents

Purpose: The purpose of this study was to analyze electrocardiographic alterations during dental implant surgeries when local anesthetic agents were used. Materials and Methods: Twenty implants were placed in 18 healthy patients. An electrocardiogram and Wincardio software were used to gather recordings from 12 static leads every 2 minutes, continuously record coronary artery (D2) derivations, and automatically measure the following electrocardiographic parameters: heart rate, duration and amplitude of the P wave, PR segment duration, ST segment deviation, QRS complex duration, and duration of the RR, QT, and corrected QT (QTc) intervals. Results: Analysis of variance of the values obtained at the different stages showed significant differences (P < .05) for the heart rate and for the duration of the RR and QT intervals. The heart rate increased during the anesthesia, incision, and bone drilling stages, reaching a peak during drilling. Duration of the RR and QT intervals decreased during the incision and drilling stages. Among the electrocardiographic parameters individually assessed, several altered values were found for the duration of the P wave, the QRS complex, and the QT and QTc intervals. Sinusal tachycardia and bradycardia, sinusal arrhythmia, supraventricular extrasystole, ventricular extrasystole, and T-wave inversion were detected. Conclusion: Dental implant placement surgery may induce electrocardiographic alterations. The most frequently found arrhythmias were extrasystole and sinusal tachycardia. The anesthesia, incision, and bone drilling stages exhibited the highest heart rate values and the shortest durations of the RR and QT intervals. INT J ORAL MAXILLOFAC IMPLANTS 2009;24:412-418

Increased resistance to first-line agents among bacterial pathogens isolated from urinary tract infections in Latin America: time for local guidelines?

Emerging resistance phenotypes and antimicrobial resistance rates among pathogens recovered from community-acquired urinary tract infections (CA-UTI) is an increasing problem in specific regions, limiting therapeutic options. As part of the SENTRY Antimicrobial Surveillance Program, a total of 611 isolates were collected in 2003 from patients with CA-UTI presenting at Latin American medical centers. Each strain was tested in a central laboratory using Clinical Laboratory Standard Institute (CLSI) broth microdilution methods with appropriate controls. Escherichia coli was the leading pathogen (66%), followed by Klebsiella spp. (7%), Proteus mirabilis (6.4%), Enterococcus spp. (5.6%), and Pseudomonas aeruginosa (4.6%). Surprisingly high resistance rates were recorded for E. coli against first-line orally administered agents for CA-UTI, such as ampicillin (53.6%), TMP/SMX (40.4%), ciprofloxacin (21.6%), and gatifloxacin (17.1%). Decreased susceptibility rates to TMP/SMX and ciprofloxacin were also documented for Klebsiella spp. (79.1 and 81.4%, respectively), and P. mirabilis (71.8 and 84.6%, respectively). For Enterococcus spp., susceptibility rates to ampicillin, chloramphenicol, ciprofloxacin, and vancomycin were 88.2, 85.3, 55.9, and 97.1%, respectively. High-level resistance to gentamicin was detected in 24% of Enterococcus spp. Bacteria isolated from patients with CA-UTI in Latin America showed limited susceptibility to orally administered antimicrobials, especially for TMP/SMX and fluoroquinolones. Our results highlight the need for developing specific CA-UTI guidelines in geographic regions where elevated resistance to new and old compounds may influence prescribing decisions.
