Growth of Chrysanthemum grandiflorum in different peats and change of peat properties during cultivation

Marketable chrysanthemums were produced in several different peat types. Only the plants in one of the dredged frozen black peats and one of the milled white peats had a significant lower shoot dry weight than those in one of the sod and milled white peats, respectively. As the N-contents of the fertilized peats show neither deficiency nor excess in nutrient supply, possibly they are not the reason for the differences in shoot dry weight. The air capacity, which is extremely low in both dredged frozen black peats and dropped further during the cultivation period due to decomposition, also cannot explain the differences in shoot dry weight sufficiently (R2=0.44*; n=12). A close linear negative correlation (R2=0.77** n=12) was found between the CAT (VDLUFA) soluble Fe and the shoot dry weight. Therefore, the Fecontents might be a quality factor of peat to be used as a growing medium.

Intraspecific variation and emendation of Hannaella kunmingensis

In order to investigate the intraspecific variability in Hannaella kunmingensis, 11 isolates, including the type strain, were analyzed for their morphological and biochemical traits. The combined internal transcribed spacer region (ITS), D1/D2 domains of the large subunit rDNA (LSU), and cytochrome b gene were examined using phylogenetic and parsimony network analyses. Our investigations revealed differences in colony morphology as well as differences in 31 out of 64 phenotypic characteristics examined, including growth in lactose, vitamin free medium, xylitol, L-arabinitol, and nitrite. Growth in the presence of 0. 1 % cycloheximide was also highlighted in H. kunmingensis. All the 11 strains were conspecific in the LSU; however, variations of about 2. 5 % were found in the ITS while isolate CBS 8356 exhibited a 27. 3 % divergence from the other strains in the cytochrome b gene. Parsimony network analysis revealed the existence of three haplotypes among the H. kunmingensis strains studied but excluded CBS 8356 from the network connecting these haplotypes. This study contributes to the knowledge of the intraspecific diversity of H. kunmingensis. To accommodate such intraspecific variations, an emendation of the species diagnosis is proposed. © 2012 German Mycological Society and Springer.

Um estudo sintático-semântico das preposições em complementos verbais de webjornais paulistas

The main goal of this work is to evaluate the realization of the linguistic phenomenon of preposition and also to investigate how current normative pressures influence the production and the perception of processes of variation and change in Brazilian Portuguese. We analyze the use of prepositions a and para in verbal complementation contexts in contemporary journalistic texts from São Paulo’s press – the web newspapers. The contexts considered are constructions with complements of direction, movement with transference, material transference, and verbal/perceptual predicators (Berlinck, 1996; Corrêa, Cançado, 2006). Because written texts tend to be more conservative (i.e. more normative) this research provides an important linguistic investigation that contributes to the sociolinguistic knowledge of the language. However, the newspapers also tend to reflect the use, so they constitute a privileged place for us to understand the conflicting relationship between ‘norm’ and ‘use’. Besides this, the research is relevant for General Linguistics for considering linguistic and extralinguistic factors which determine the use and frequency of the prepositions, like syntactic-semantic relations between the preposition, the verb, the complement, and the text genre. We collected data from web newspapers from Araraquara, with small and medium circulation. Based on previous results, we have ascertained the predominance of the use of the preposition a in the newspapers from São Paulo in the 20th century. However, we have also ascertained representative records of variation... (Complete abstract click electronic access below)

Preposições em textos do gênero notícia na imprensa paulista: norma e uso no ínicio do século XX

This paper proposes a reflection on processes of variation and change that occurred with the portuguese prepositions a, ate, em and para, taken as a parameter for answers in a broader context, the confrontation between the norm and use and between standard and linguistic variation. We conducted the study based on a corpus composed of all occurrences of the prepositions in question removed news of the newspaper O Combate and O Estado de Sao Paulo. Whereas the main objective of the study is to present and describe the use of these particles in newspaper articles of the Imprensa Paulista, data were collected and quantified by using the statistical package GOLDVARB, and interpretation of results relied (i) assumptions regarding the process variation in the use of prepositions and prepositions replace weak, as the preposition to, for strong prepositions (para, em, até), (ii) in comparison with the grammatical rule in effect at the time, (iii) and in the search for the existence of some historical factor that justifies the selection of a preposition rather than another. Among the hypotheses, we investigate the relationship between these prepositions and whose kind of preachers they introduce supplements: the direction of motion (abstract or concrete) or transfer (material and verbal / perceptual). This theoretical perspective was the Labovian sociolinguistics (Labov, 1972, 1994), which defines the linguistic variable as a representation of two or more different ways to convey a certain information content, being necessary to define it the following criteria set exact number of variants to establish all the multiplicity of contexts in which it appears; develop a quantitative index for measuring the values of variables

Como o ensino vê a variação?

Thinking about the correlations between linguistic variation and education is both necessary and urgent if we wish to make language teaching more appropriate, fairer and more meaningful. I take, on one hand, already well-established concepts derived from research on language: the variable nature of language (in space, time, situations) and the intrinsic relationship between this variation and social structure, the communicative needs of speakers, the needs and desires that speakers have to build their social identity. On the other hand, we found out that the teaching of Portuguese language has usually been based on a vision that assumes the language as a static reality. I propose to contrast the two components of this issue, to reveal where, and if, any relationship has been established, and where it is to be built. In the first instance, I seek to evaluate the bond – how one speaks about change when this issue comes to be focused; in the second, I seek the reasons for absence - ignorance or indifference?

Variação e mudança linguística: panorama e perspectivas da sociolinguística variacionista no Brasil

Since the 1970s many research groups have emerged in Brazil in the area of Sociolinguistics, seeking to investigate language in relation to social factors that distinguish different speech communities to deconstruct the idea of linguistic homogeneity. Many of the works have been based on variationist sociolinguistics (LABOV, 2008 [1972]), for which variation and change are inherent to languages, i.e., heterogeneous structures are part of the speakers’ linguistic competence, as a cultural phenomenon motivated by linguistic and extralinguistic factors. Our aim, in this article, is to address the paths of Sociolinguistics since its beginning as a science, focusing mainly on the variationist strand, by recalling its key-concepts and methodology, and to present an overview of the research works conducted in Brazil in this field nowadays.
