The objective of this work was to evaluate the possibility of mapping adsorbed phosphorus through soil color and magnetic susceptibility. The experiment was done in a 380-ha sugarcane area, which included four types of Oxisols, with different texture and natural fertility. Two hundred and forty-one soil samples were collected at 0.00-0.25-m depth. The soil redness index was calculated from sample values of hue, value, and chroma, obtained with diffuse reflectance spectroscopy. Regression models were adjusted between adsorbed phosphorus and soil magnetic susceptibility or redness index. Data spatial dependence was evaluated with geostatistics. Magnetic susceptibility is significantly correlated to adsorbed phosphorus, which allows it to be used as a component in pedotransfer functions for indirect quantification of soil adsorbed phosphorus. The redness index and the magnetic susceptibility show spatial dependency with adsorbed phosphorus. Soil magnetic susceptibility and redness index, evaluated with diffuse reflectance spectroscopy, can aid in the mapping and identification of areas with different phosphorus adsorption potential.

Apresentando uma síntese histórico-sociológica do panorama rural brasileiro, da constituição do ensino técnico, e do desenvolvimento do ensino técnico agrícola, este artigo defende que as escolas técnicas agrícolas sofrem uma dupla marginalização, por um lado proveniente de sua natureza profissionalizante e, por outro, dada sua vinculação com o meio rural brasileiro.

This essay sketches some principles according to which a research project called “Mapping of math teacher education and practice in Brazil” is been conducted by a group of researchers with the objective of understanding the way policies related to teacher education and practice are effectively implemented in different regions of the country. The main objective of this article is, therefore, to discuss the pressupositions of this project, its foundation, the basic beliefs in which it is rooted. In order to emphasize such principles, some remarks on theorization, methodology, teacher education, narratives and on the concept of mobilization/apropriation are done. The essay is based on a metaphor built on cartographical practices.

This article has the objective to describe the importance of management knowledge. And, for that, we have done a study upon a case, based on the mapping of the process of classes distribution in the Escolas Técnicas do Centro Paula Souza. The management of knowledge is a way to provide it to the people, considering that knowledge becomes a fundamental and necessary resource to the development of the privante or public organizations. The use of knowledge maps becomes a crucial factor in this process of transformation of tacit knowledge into explicit, because having a high knowledge level, and socialize it, is as essential and important as all the other resources that exist within the institutions.

The quantitative research conducted on communication in organizations from bauruenses has served as inspiration for: the development of applied research regarding Brazilian organizational reality, to the communication courses and on the improvements in the communication aspect of the organizations in the region. The goal is to provide information related t the role of organizational communication and the public relations role in this process, measuring the empowerment of this community. The mapping methodology is based on structured questionnaires in order to capture ordinary factors, active and retroactive, from the communication processes such as: relationship types, channels and media, degree of interaction and interdependence between the parties; types of public involved in the process and the expectations of the organization in relation to goals, objectives, actions, events and activities programmed in communication. For the delineation of a reflective proposal from the data, we chose to work on analyzing three dimensions: the strategic communication, linked to the business model and information technologies; the internal communication, linked to culture, to the organizational structure and management that implies the new paradigms of relationship; and lastly, the intention to materialize the collected data on indicators and scales from attributes caused or inhibited from the excellent communication, including evaluation of the practice of Public Relations. This article presents the main results related to micro companies in Bauru, São Paulo.

The study took place in a sewage treatment plant located at the actual Department of Water and Sewer in Bauru, city of Sao Paulo state. This treatment plant has an average entrance flow of 4.8 l. s-1 made by upflow anaerobic filter, followed by wetland systems constructed in parallel. . As objective of this study we evaluate the effectiveness of three systems of constructed wetlands, with three different types of plants (Lily pond, Giant papyrus and Cattail),quantify, and qualify the effluents at various stages of treatment to monitor their effectiveness and the possibility of reuse in agriculture. There was a satisfactory removal of organic matter, with a mean concentration of 36 and 39mg.l-1 at the , phases 1 and 2 of the operation, respectively. The constructed wetlands effluent nitrogen and phosphate concentrations were high throughout all the system and the removal efficiency of ammonia nitrogen was much lower than expected, then the system is functioning as secondary treatment and not as tertiary treatment. The concentrations of micro-organisms found in the final effluent were also high. Therefore, it is concluded that the results of removal efficiency of organic matter, of constructed wetland systems, meet the parameters required by legislation for effluent discharges but do not attend the parameters required for nitrogen and micro organisms. This way, these analyzed plants effluents are suitable for reuse in agriculture restricted irrigation

This article aims to identify patterns in the organization of innovation network by mapping the network inventors of a cosmetics company and identifying ways to promote innovation capacity through interconnectivity. The research was conducted through case study methods, and, for this, inventors mappings were made, based on the records of patents previously surveyed, taking into consideration the linkage (internal or external) of each inventor with the company and also the amount of patent citations. It was identified higher hierarchy in networks with the presence of collaborators externals to the company as well as a possible higher technological content, since the amount of citations was higher compared to other networks. It is verified, finally, that inventors mappings (although a patent is not the only measuring factor of innovation) can identify key features to help a better management of innovation.
