Discutindo a educação ambiental no cotidiano escolar: desenvolvimento de projetos na escola formação inicial e continuada de professores

A presente pesquisa buscou discutir como a Educação Ambiental (EA) vem sendo trabalhada, no Ensino Fundamental e como os docentes desta escola compreendem e vem inserindo a EA no cotidiano escolar., em uma escola estadual do município de Tangará da Serra/MT, Brasil. Para tanto, realizou-se entrevistas com os professores que fazem parte de um projeto interdisciplinar de EA na escola pesquisada. Verificou-se que o projeto da escola não vem conseguindo alcançar os objetivos propostos por: desconhecimento do mesmo, pelos professores; formação deficiente dos professores, não entendimento da EA como processo de ensino-aprendizagem, falta de recursos didáticos, planejamento inadequado das atividades. A partir dessa constatação, procurou-se debater a impossibilidade de tratar do tema fora do trabalho interdisciplinar, bem como, e principalmente, a importância de um estudo mais aprofundado de EA, vinculando teoria e prática, tanto na formação docente, como em projetos escolares, a fim de fugir do tradicional vínculo “EA e ecologia, lixo e horta”.Facultad de Humanidades y Ciencias de la Educació

Use of unmanned aerial vehicles (UAVs) and photogrammetric image analysis to quantify spatial proximity in beef cattle

Spatial proximity is an important metric in cattle behaviour, which is used to study social structure, dyadic relationships, as well as grazing and maternal behaviours. We developed an efficient, novel, non-invasive method to quantify the spatial proximity of beef cattle by using UAV-based image acquisition and photogrammetric analysis. Orthomosaics constructed by images obtained from UAVs were used to measure, with an accuracy of ±1.96 m (95% likelihood), the inter-individual distances between cows and calves. Aerial videos of the calves and their dams, held in a 5 ha pasture, were made over four days using UAVs. We used two UAVs to video-capture the following: (i) the location of all individuals (UAV flown at 100 m) and (ii) the identity of cow–calf pairs (UAV flown at 15–30 m). Still-images extracted from the UAV-acquired video screenshots were used to produce orthomosaics. The orthomosaics captured all the cows and calves in a single image, from which we measured the distance between related and non-related cow–calf pairs. This UAV-based orthomosaic method clearly showed that members of related pairs were closer than non-related ones, and that the distance was greater in the evening, demonstrating the utility of UAVs to accurately measure cattle spatial proximity.The accepted manuscript in pdf format is listed with the files at the bottom of this page.

Rapid shifts in migration routes and breeding latitude in North American bluebirds

Abstract Spatial and temporal shifts in the migratory patterns of birds have become more frequent as climate change and habitat alteration continue to impact ecosystems and the species dependent on them. In this study, we used eBird community science data collected over ten years to examine potential changes in the migratory patterns of three North American bluebird species: eastern (Sialia sialis), western (Sialia mexicana), and mountain (Sialia currucoides) bluebirds. Community science datasets such as those provided through eBird are a valuable tool for examining population‐level processes, as such data are often costly and time‐consuming to collect through other approaches (e.g., directly tracking individuals). Using generalized additive models, we produced smoothed migration paths for all three species over each season from 2009 to 2018. We asked whether there were changes over this 10‐year period in the timing of spring and fall migration and migration speed, and the population centroids during breeding and migration. In contrast to many species that are experiencing poleward shifts in their distributions, the population centroids during the breeding period of all three bluebird species appear to have shifted southward over the past decade. Perhaps most surprisingly, we also detected strong longitudinal shifts in the population centroids during migration in eastern and western bluebirds, with both species shifting toward the center of the continent. Despite these changes in migratory routes and breeding distributions, we detected no change in the migratory timing or speed of any of the species. Our analysis indicates that bluebirds are rapidly altering the pattern of their migration, likely in response to changing environmental conditions, but not always in the direction predicted

Ethical codes and cultural context: ensuring legal ethics in the global law firm

There are doubtless many practical and professional problems that arise in the global legal practice, but this paper suggests that not least of these are issues of legal ethics, in part generated by the global context and not easily amenable to resolution by reference to any single code within the “home” or “host” jurisdiction. For example, there may be difficulties in isolating precisely what those ethical obligations might comprise. These obligations might be rooted in the requirements of local law, but they might arise equally from the values and expectations of the client, or from other lawyers whether inside or outside of the firm in question. The common expectation of regulatory control exercised by a professional bar may be replaced by a fluidity in which clearly defined rules and duties are not easily discernible. The questions that this paper seeks to answer are: How might lawyers best be provided with and follow ethical approaches appropriate to the delivery of global legal services, and what is the role that firms might play in achieving this

Randomized Trial Examining the Effect of Two Prostate Cancer Screening Educational Interventions on Patient Knowledge, Preferences, and Behaviors

OBJECTIVE: To assess the effect of video and pamphlet interventions on patient prostate cancer (CaP) screening knowledge, decision-making participation, preferences, and behaviors. DESIGN: Randomized, controlled trial. SETTING: Four midwestern Veterans Affairs medical facilities. PATIENTS/PARTICIPANTS: One thousand, one hundred fifty-two male veterans age 50 and older with primary care appointments at participating facilities were randomized and 893 completed follow-up. INTERVENTIONS: Patients were randomized to mailed pamphlet, mailed video, or usual care/control. MEASUREMENTS AND MAIN RESULTS: Outcomes assessed by phone survey 2 weeks postintervention included a 10-item knowledge index; correct responses to questions on CaP natural history, treatment efficacy, the prostate-specific antigen (PSA)'s predictive value, and expert disagreement about the PSA; whether screening was discussed with provider; screening preferences; and PSA testing rates. Mean knowledge index scores were higher for video (7.44; P = .001) and pamphlet (7.26; P = .03) subjects versus controls (6.90). Video and pamphlet subjects reported significantly higher percentages of correct responses relative to controls to questions on CaP natural history (63%, 63%, and 54%, respectively); treatment efficacy (19%, 20%, and 5%), and expert disagreement (28%, 19%, and 8%), but not PSA accuracy (28%, 22%, and 22%). Pamphlet subjects were more likely than controls to discuss screening with their provider (41% vs 32%; P = .03) but video subjects were not (35%; P = .33). Video and pamphlet subjects were less likely to intend to have a PSA, relative to controls (63%, 65%, and 74%, respectively). PSA testing rates did not differ significantly across groups. CONCLUSIONS: Mailed interventions enhance patient knowledge and self-reported participation in decision making, and alter screening preferences. The pamphlet and video interventions evaluated are comparable in effectiveness. The lower-cost pamphlet approach is an attractive option for clinics with limited resources
