Atributos químicos e matéria orgânica em complexos florestais periodicamente inundados na restinga da marambaia - RJ

This study aimed to evaluate and characterize the chemical properties of soil organic matter under two periodically flooded forest formations on the island of Marambaia, Rio de Janeiro. These formations differ on the degree of soil water saturation, caused by the influence of water table, and in the (F1) formation presents the water table nearer the surface compared to the (F2) formation. Samples were collected in layers from 0.00 to 0.05, 0.05-0.10 and 0.10-0.20 m. The soil properties evaluated were: pH, H+ + Al+ 3, Ca+2, Mg+2, Na+, K+, P, N, total organic carbon (TOC) and base saturation (V%), humin carbon fraction (C-HUM), carbon of humic acid fraction (HAF-C) and fulvic acid fraction carbon (FAF-C). Statistically higher pH values were observed for F1. In F2 there are higher values of Mg+2, P, N and V% value. Correlation was found between the concentrations of Mg+2, N, humic acid and fulvic acid with water table in F1, and water table in F2 with Na+ and K+. Fraction C-HUM was more representative of the total organic carbon, followed by C-HAF and C-FAF. The TOC levels were higher in F1. The C /N ratio was lower in F2, with values ranging between 9 and 12, and F1 were found higher values of this relationship, ranging from 9 to 15. Among the pathways of formation of organic soils in both areas it appears that the major route for organic matter accumulation is the inheritance route.

O processo de formação de conceitos na perspectiva vigotskiana

In his work on human knowledge, Vygotsky reveals the second human nature, the one which is historical and cultural, due to people´s learning throughout life, through the mediation of others and the concrete conditions of life and education. In this eminently social process, the child grows into the intellectual life having the adult as a peer and learns human skills from this adult-child interaction. This means that, for working with abstract formulation, it is necessary understanding it as a complex, dynamic and functional act that is built by the insertion of individual performance into culture that is mediated by interaction with others. In this setting, each individual reaches knowledge through formal and non-formal learning that help on the formulation of scientific and everyday concepts. To make studies on the process of concept formation, Vygotsky adopted an experimental methodology based on the philosophical assumptions of Marxist theory of how mental processes occur, once he perceived these processes in a constantly changing and moving. Thus, the method called “Instrumental, Cultural and Historical” differed from conventional experimental studies focused on the performance of the task itself. The method adopted by Vygotsky was concerned with the process of concept formation and not only with fragmentary cutouts of cognitive processes. According to our study, the formation of the social nature of man develops from processes of appropriation and objectification of knowledge, which makes individual the historically constructed achievements by mankind, as, for example, types of sophisticated thinking, which requires the discussion of concept formation.

Influência de procedimentos educativos sobre os conceitos de berçários

The duality care-education is an aspect to be considered in the routine of childhood education institutions that have a nursery. The concepts of professionals who work in the nursery interfere with the developed practice, and require great concern regarding the continuing education. The objective of this study was to verify the effects of educational procedures on the concepts related to functions and benefi ts of the nursery for the child – from the professionals who work in a childhood education institution. These professionals were teachers and development assistants from municipal nurseries of Marília, interviewed four times – initially, after each of the two rearing procedures, and six months after the procedures. These procedures consisted of educational workshops, once a week, for one month, and 15 hours of supervised practices in the nursery. Both practices focused on the activities and their benefi ts to the child’s development. We found that the educators’ knowledge comes from common sense, and that educational workshops provided changes on their information levels, which were strengthened by supervised practice. The analysis indicates that the initial and continuing education of professionals need to consider specifi c aspects of child development, so more adequate concepts are built.

Rede de coautoria institucional em Ciência da Informação: uma comparação entre indicadores de rede e os conceitos CAPES

The objective of this is study is to point inter-institutional partnerships in Information Science formed through co-authorship network. More specifically, we calculate indicators of centrality degree, betweenness centrality and closeness centrality, and analyze the relationships between the grades attributed by CAPES - Coordination for the Improvement of Higher Education Personnel - to the institutions and the indicators on the network, checking whether there is proximity and similarity between network indicators and CAPES's grades. Our corpus consisted of all articles published in the four journals in the field of Information Science in Brazil, with regular publications, based in SciVerse Scopus, for the 2010- 2012 period. We retrieved 237 articles, 58 co-authored, with 117 participant institutions. We conducted the analysis of relations between institutions with greater grades by CAPES and the network through centrality indicators. It was concluded that these network indicators and CAPES concepts are articulated, harmonizing these two categories of indicators.

As organizações e a ISO 26000: revisão dos conceitos, dos motivadores e das barreiras de implementação

ISO 26000, published in 2010, focuses on corporate social responsibility. This study presents a systematic review conducted in ISI Web of Knowledge (Web of Science) and Elsevier's Scopus databases to answer the following question: What are the barriers and motivators affecting the adoption of ISO 26000 by organizations? The articles were selected using filters that applied two inclusion criteria. The data were summarized in a table covering the concepts of ISO 26000, the motivators, and the barriers. The motivators were globalization or competition in international markets, congruence with management systems, reputation or image, relationship with employees and improvement of the organizational environment, improvement in the relationship with external stakeholders, competitive advantage and strategy, guide to corporate social responsibility (CSR), and reduction of business risks. The barriers were lack of alignment between CSR and organizational strategy; business (national and international); unfamiliarity with ISO 26000; lack of communication, tools and sensitivity to the subject; short-term focus; knowledge management; fear of not fulfilling the standard; and financial resources. Finally, an agenda for future studies was prepared.

Síntese e atividade biológica de complexos de metais de transição com hidrolisados proteicos da clara do ovo

Trabalho trata da síntese e caracterização de quelatos inéditos de prata, paládio e platina contendo proteínas hidrolisadas da clara de ovo. A ideia consiste em preparar e utilizar quelatos metálicos contendo ligantes de origem natural, como metalofármacos. A pesquisa realizada pode ser dividida em três etapas. A primeira, referente à hidrólise e análise do hidrolisado proteico da clara de ovo. Diversos métodos e condições experimentais foram testadas a fim de se encontrar as condições de hidrólise mais adequadas (natureza da enzima, tempo, pH, temperatura, relação enzima:substrato) para a obtenção de aminoácidos livres e/ou pequenos peptídeos. A segunda parte consistiu na obtenção de compostos de coordenação de platina, prata e paládio contendo o hidrolisado proteico. Nessa etapa, diferentes rotas sintéticas e condições experimentais também foram utilizadas. Além disso, a espectroscopia vibracional no infravermelho foi utilizada nessa etapa para investigar as características estruturais (particularmente, os grupos funcionais presentes) dos compostos metálicos obtidos bem como da matéria prima utilizada (clara de ovo). Após inúmeras tentativas de síntese, três amostras promissoras, do ponto de vista da Química de Coordenação, foram obtidas, a saber, CO-Pd2, CO-Pd9 e CO-Ag3. Ensaios biológicos preliminares, que consistiu na terceira e última parte deste trabalho, foram realizados no sentido de avaliar a capacidade inibitória de crescimento das bactérias S. aureus e E. coli, através da determinação da Concentração Inibitória Mínima (CIM) dos compostos metálicos obtidos.
