Alterações morfoanatômicas foliares da cana-de-açúcar na fase de estabelecimento em condições de matocompetição

Aiming at the assessment of the production parameters and leaf tissues morph anatomical possible changes of the sugar cane RB 86 7515 variety in its establishment phase in the conditions of weed competition, a study over vases has been accomplished in the city of Dracena, São Paulo State, from April to June, 2010, at Universidade Estadual Paulista Júlio de Mesquita Filho. The species Brachiaria brizantha e Brachiaria decumbens, which are regarded as invaders, were used. It was also used the Completely Randomized Design with seven treatments and five repetitions, totalizing 35 lots or vases. The treatments ranged according to the number of Brachiaria brizantha and Brachiaria decumbens seeds, as it follows: T1 - no occurrence of weed competition; T2 - low occurrence of weed competition with Brachiaria brizantha; T3 - medium occurrence of weed competition with Brachiaria brizantha; T4 - high occurrence of weed competition with Brachiaria brizantha; T5 - low occurrence of weed competition with Brachiaria decumbens; T6 - medium occurrence of weed competition with Brachiaria decumbens, and T7 - high occurrence of weed competition with Brachiaria decumbens. There was an evaluation over the following issues after 60 days of the sugar cane plantation and the invading plants: the weight of the total dry matter of the plants, the thickness of the upper surface epidermis or adaxial, the thickness of the lower surface or abaxial, the thickness of the mesophill, the thickness of the limbo, the diameter of the xylematic vessels and the diameter of the phloem vessels. The weed competition of the species Brachiaria brizantha e Brachiaria decumbens, which are considered as invaders, provoked some reduction of the morph anatomical characteristics and of the sugar cane production. In general, the Brachiaria decumbens was the species which mostly influenced the leaf thickness of the sugar cane in negative aspects.

The Digital Divide in the University: The Appropriation of ICT in Higher Education Students from Bogota, Colombia

The growth and integration of ICTs in the global economy have created conditions that profoundly affect our society, dividing communities between those who effectively appropriate these resources and those who do not, what is called the digital divide. This exploratory study seeks to propose and validate ways of assessing this phenomenon in higher education, from the construction of a model and a comprehensive methodology that value contextual conditions, in addition to measuring access factors and motivation for use, that have been employed in previous research. To obtain indications about the behavior of this phenomenon, we developed research with students from three universities in Bogota, administering 566 surveys in four phases that would test the variables proposed in the model. The results show that the variables of the model link causally, with the strongest relations between education, attitude towards ICTs and ICT application. Although students have good access to ICTs and high levels of education, no strong relationship was found in regards to perceived impact on production. This may be explained by a superficial appropriation of ICT, due to a context that is alien to its conditions of origin (industrialism, innovation), poor quality of education and economies not centered around R&D.

Fenologia reprodutiva e distribuição espacial de Oeceoclades maculata (Lindl.) Lindl. (Orchidaceae) em Cerrado do município de Mogi Guaçu, São Paulo, Brasil

Oeceoclades aculate (Lindl.) Lindl., an invasive orchid, was analyzed as to its reproductive phenology and spatial distribution, correlation between abundance of mature and immature individuals, and verifying these with microclimate patterns in the Cerrado (savanna-like vegetation) of Mogi Guacu, Sao Paulo State, Brazil. For the reproductive phenology 100 plants were followed and the distribution pattern was identified by the Morisita Index (MI) and the Variance Ratio/Average (R) in 20 plots of 20x10m, reduced to 10x10m afterwards. The phenology presented seasonality, with flowering from November to February, fructification from February to June, and dehiscence from June to July. Mature and immature individuals aggregated and correlated to each other, indicating dependence between the ontogenetic stages. The luminosity was the preponderant microclimatic factor in the allocation of plants. Seasonal climatic changes and intensity of anthropogenic disturbances seem to be more important for the establishment of the species than microclimate.
