Historic emissions from deforestation and forest degradation in Mato Grosso, Brazil: 1) source data uncertainties

<p>Abstract</p> <p>Background</p> <p>Historic carbon emissions are an important foundation for proposed efforts to Reduce Emissions from Deforestation and forest Degradation and enhance forest carbon stocks through conservation and sustainable forest management (REDD+). The level of uncertainty in historic carbon emissions estimates is also critical for REDD+, since high uncertainties could limit climate benefits from credited mitigation actions. Here, we analyzed source data uncertainties based on the range of available deforestation, forest degradation, and forest carbon stock estimates for the Brazilian state of Mato Grosso during 1990-2008.</p> <p>Results</p> <p>Deforestation estimates showed good agreement for multi-year periods of increasing and decreasing deforestation during the study period. However, annual deforestation rates differed by > 20% in more than half of the years between 1997-2008, even for products based on similar input data. Tier 2 estimates of average forest carbon stocks varied between 99-192 Mg C ha^-1, with greatest differences in northwest Mato Grosso. Carbon stocks in deforested areas increased over the study period, yet this increasing trend in deforested biomass was smaller than the difference among carbon stock datasets for these areas.</p> <p>Conclusions</p> <p>Estimates of source data uncertainties are essential for REDD+. Patterns of spatial and temporal disagreement among available data products provide a roadmap for future efforts to reduce source data uncertainties for estimates of historic forest carbon emissions. Specifically, regions with large discrepancies in available estimates of both deforestation and forest carbon stocks are priority areas for evaluating and improving existing estimates. Full carbon accounting for REDD+ will also require filling data gaps, including forest degradation and secondary forest, with annual data on all forest transitions.</p

Text and Interaction: A Performance Analysis Written in Present Evaluations of Pedagogy Students in the Distance Mode

This study aims to verify the use and mastery of linguistic knowledge in the writing process of Pedagogy students, in the form of Distance Education. The methodology was based on an exploratory analysis of texts produced in the face-to-face assessments that occurred in the first half of 2017. In the analysis of the answers, a descriptive graph of the errors and inadequacies observed was presented. The results show the commitment of writing to the meaning of the text, since this is a result of it. With this study, it was noticed that the university students have presented difficulties in expressing, in writing, their thoughts, their understandings and their opinions in an adequate and coherent way. Therefore, in order to minimize the anxiety experienced by these students at the time of writing, it is suggested that through the Instrumental Portuguese class, which part of the curriculum is, the linguistic aspects responsible for the production of meaning in texts and the interaction of the interlocutors. In order to meet the needs of undergraduate students, in the specific case of Pedagogy, since it concerns the training of teachers, professionals who will work in the literacy of children and young people and need to prioritize knowledge about language, reading and writing of these students

Virtual Environment, Digital Hypertext, Reading and Writing in Foreign Language

This work intends to analyze - in an activity carried out with students from the third period of the Language (Spanish) undergraduate course of a college located in Itaperuna, a town in the State of Rio de Janeiro, Brazil - how the digital hyper textual reading can facilitate the selection of information in order to facilitate the writing process of texts in Spanish that can be broadcasted in the virtual environment, verifying how this may happen, so that these productions are shared, also allowing the interaction of the subjects with the language and with their peers. For this objective, we used the qualitative methodology (Erickson, 1986) with action research, seeking foundation in what theorists such as L&eacute;vy (1996, 1999), Coscarelli (2006, 2009), Gomes et al. (2015), Bannell et al. (2016), among others, investigate. As results, we emphasize that the subjects of the research actively participated in the construction of their own learning regarding the aspects covered in the foreign language class, and with this they were able to practice reading, writing, and the USAge of the vocabulary and grammar studied. Finally, we conclude that the hypertext worked here as an inclusive device, facilitator of reading and propitiator of writing, making the participant students authors of digital texts that provided them with learning throughout all the process they have been through

Characterization of Soybean Cultivars for Biodiesel Production

Due to environmental issues involving the polluting gasesemission, Brazil has adopted the policy of using oil and biodiesel. For biodiesel production, the main raw material used in Brazil is soybean oil. The development of the numerous genotypes of this culture has always considered quantitative aspects. The objective was to qualitatively characterize 12 soybean cultivars for biodiesel production. The experimental design was randomized blocks with three replicates. The cultivars were sown in December 2016, in no-tillage system, in Ponta Grossa, Paraná, Brazil (-25.093056, -50.063327 UTM). The analyzed variables were: oil and protein contents, acidity index and specific mass. It was concluded that there were no significant differences among the cultivars for oil and protein contents. For the variables acidity index and specific mass, there were significant differences among the cultivars, being below the limits established by the Brazilian legislation for vegetable oil, but with potential for biodiesel production

Expressions of the Individual’s behavior in Digital Network: Education in a Technological Society

The article assumes that the behavior of expressions of individuals is related to the digital network, in which forms of human relationships are being forged in order to understand differently the process of teaching and learning with autonomy that can generate a new way of thinking, creating values and representations. This may resize behaviors in individuals and affect the perception of the subject in relation to themselves and others. New technologies, consumption and media influence shape and build the contemporary psyche. Thus, it becomes essential to consider the force with which the new messaging serving media plays in order to socialize and in the individual subjectivity. In this context, new challenges for education that allow the birth of studies and concepts, in order to explain this new reality and to contribute to the art of teaching and learning. One of these, therefore, will be part of this work, which is called Informational Normosis or Informatosis

School Evasion in the Brazilian trends: analyzing the vectors that influence students’ decision to interrupt their formative process

Research data demonstrate that the analyzes built around School Evasion considers, primarily, the quantitative metrics of studentsrsquo; entry and exit and also the monetary losses, especially because it would be incoherent not to take as reference the goals and objectives outlined for education school system. However, analyzing the vectors that influence studentsrsquo; decision to interrupt their formative process, according to purely numerical criteria, would imply in ignoring the function of educational institutions and the real causes/reasons stemming from the social and relational demand of students' passage on educational institutions. For this reason, problematizing some of the recurring issues and incidents generated by certain investigations seems instigating and challenging. If in on the one hand, the attitude of understanding the conceptualization, the investigative tendencies and the characteristics of the studies give rise to certain criticisms that put in check the complexity of the object in question, on the other, it can stimulate the construction of other tendencies, new pathways, other possible ways of overcoming the gaps identified in the studies about School Evasion in Brazil

Handling Time and Bite Mass Mechanisms in Large Herbivores: Contrasts between Sward Structure and Grazing Methods

Grazing is a time-dependent process where jaw movements of prehension, handling and chewing compete with them (Laca et al. 1994; Ungar et al. 2006). The grazing efficiency is dependent of bite mass and time per bite. Bite mass has been related to sward structure by forage height, structural components (Cangiano et al. 2002). In rotational stocking this effect becomes more pronounced, especially under high grazing down levels. Consequently, there is a progressive reduction in short-term intake rate (Fonseca et al. in press). New management targets should be proposed based on the predominant influence of sward structure in short-term intake rate by grazing animals (Carvalho et al. 2007). We hypothesise that intake potential of animals grazing tropical pastures will be reduced due to higher constraints in bite formation when compared to temperate pastures. This study aimed to investigate the intake process of heifers under the influence of different sward heights and grazing down levels in two contrasting - tropical and temperate - forage species

A Strategic Location Model of Stationary Production Units: A Case study in the Albacora Leste field

The imminent interest in issues related to the oil and gas sector has always proved to be a profitable source of investment and research, with incremental gains and innovations in the various sectors of the offshore industry. Particularly in the context of resource localization, the adoption of mathematical models presents itself as a challenging theme. In this context, the research has the purpose of proposing a localization model of Stationary Production Units (SPU) of an oilfield located in the Campos Basin, Rio de Janeiro (Brazil). The computational tests were conducted using the Lingo software, based on data from the Albacora Leste field. The results of the proposed model demonstrated a reduction of approximately 12% in the configuration costs, compared to the current location

Proposal of a virtual collaborative news environment: an interdisciplinary study

The main objective of this work is to demonstrate the advances made by the CATI research group with regard to the proposal to create a virtual collaborative news environment (AVNC) , to be initially implemented at the Northern Fluminense Darcy Ribeiro State University(UENF) through the Postgraduate Program in Cognition and Language. This interdisciplinary environment involves concepts from the area of communication, administration and information technology and seeks to meet the demands of generation, storage, retrieval, processing and transmission of information in this digital age. The AVNC involves three research fronts: rethinking the logic of news production, structuring a platform that is collaborative and defining what a business and management model should be that can give sustainability to this environment. In today\u27s world, it is important to consider the reader\u27s increasingly active participation in journalism, through information and communication technologies, thanks to the social changes that come with them. In times of cyberspace and cyberculture, it is necessary to rethink the dynamics of journalistic production. For this, authors like Pierre Lévy, Lúcia Santaella, Henry Jenkins, Caio Túlio Costa, among others were searched. In an era in which forms of collaborative ownership prevail, the platform being considered in this research follows the 3C collaboration model, according to Michalsky, Mamani, and Gerosa. A global platform where individuals interact, communicate, collaborate and gather information requires a business model and management that assists in managing the collaborative virtual news environment. For this, we used authors such as Alex Osterwalder, Eric Flamholtz, Siqueira and Crispim, Campos, among others. With this, an increasingly intelligent and collaborative environment is expected, with the active participation of all the agents involved. That is, what is proposed is the total interaction of the Internet user-reader
