Impacto da adubação orgânica sobre a incidência de tripes em cebola.

Analisou-se a relação entre adubação orgânica e a incidência de Thrips tabaci Lind. em cebola (Allium cepa L), na EE de Ituporanga,entre agosto e dezembro de 1998. Os tratamentos foram determinados de acordo com a necessidade de N para a cultura pela análise de solo. Empregou-se como fonte orgânica diversos adubos fornecendo 75 Kg/ha de N (esterco suíno; adubo Barriga Verde proveniente de esterco de aves; composto orgânico; esterco de peru; húmus); 37,5 Kg/ha de N (metade da dose normal com esterco de suíno); as testemunhas foram adubação mineral fornecendo 30-120-60 kg/ha de N-P2O5-K2O e o dobro da dose (60-240-120 kg/ha de N-P2O5-K2O); e testemunha sem adubação. Nenhum tratamento apresentou incidência de T. tabaci superior à testemunha sem adubo. A adubação mineral em relação à orgânica não favoreceu significativamente a incidência de T. tabaci . O processo de conversão do manejo do solo da área experimental de convencional para orgânico pode ter favorecido a infestação similar do inseto entre tratamentos. No período de maior incidência de T. tabaci, a relação com nutrientes foi descrita por um modelo envolvendo K/Zn, B e N de maneira positiva. A correlação entre nutrientes e T. tabaci não foi linear na maioria das avaliações. A adubação orgânica pode substituir a adubação mineral na cultura da cebola, pois foi possível atingir níveis de produtividade similares para ambos tratamentos

That's not a narrative; this is a narrative: NAPLAN and pedagogies of storytelling

For the past eight years, Australian school students in Years 3, 5, 7 and 9 have engaged in the National Assessment Program - Literacy and Numeracy (NAPLAN) writing test, with a one-in-two chance they will be tasked with producing a 'narrative' genre. This paper examines the way in which the very notion of storytelling and narrative is conceptualised in the NAPLAN supporting documentation, and its potential negative consequences. The paper begins by providing a review of the literature on storytelling, paying particular attention to research which has established the 'Complication- Resolution' narrative as one type of storytelling. It then provides an account of how story and narrative are typically characterised and defined in the official NAPLAN documentation, that is, as the 'Complication-Resolution' narrative exclusively. The final section of the paper presents a genre analysis of eight student writing samples and the related comments and gradings from the NAPLAN narrative marking guide. The analysis found a number of student texts in the marking guide that were effectively structured stories, but which had been marked down for Text Structure because they did not comply with the specific structure of the 'Complication-Resolution' narrative. The analysis also found a number of texts that scored highly with respect to the Text Structure criterion, even though they were not instances of the Complication-Resolution narrative sub-type. Drawing on these findings, the paper argues that various inconsistencies and points of apparent confusion in these comments and gradings can be taken as evidence that other sub-types of storytelling are being inappropriately devalued, and that ultimately, there is a lack of understanding in the nature of storytelling in the NAPLAN documentation. By way of conclusion, the paper reflects on some of the negative consequences that may flow from storytelling being defined in this limited way, including the implications for how storytelling is taught by teachers and caregivers, the potential misdirection of students as to what constitutes a 'good' story, as well as the cultural implications of limiting stories to one specific type.Toby Freeman, Hailay Abrha Gesesew, Clare Bambra, Heather Brown, Shahid Ullah, Jennie Popay, and Fran Bau

Investigating evaluation and news values in news items that are shared through social media

The sharing of news through social media platforms is now a significant part of mainstream online media use and is an increasingly important consideration in journalism practice and production. This paper analyses the linguistic characteristics of online news sharing on Facebook, with a focus on evaluation and news values in a corpus of the 100 ‘most shared’ news items from ‘heritage’ English-language news media organisations. Analyses combine corpus linguistic techniques (semantic tagging, frequency analysis, concordancing) with manual, computer-aided annotation. The main focus is on discursive news values analysis (DNVA), which examines how news values are established through semiotic resources, enabling new empirical insights into shared news and adding a specific linguistic focus to the emerging literature on news sharing. Results suggest that all ‘traditional’ news values appear to be construed in the shared news corpus and that there is variety in terms of the items that are widely shared. At the same time, the news values of Eliteness, Superlativeness, Unexpectedness, Negativity and Timeliness seem especially important in the corpus. The findings also indicate that ‘unexpected’ and ‘affective’ news items may be shared more, and that Negativity is a more important news value than Positivity

The Trial of the Expert Witness: Negotiating Credibility in Child Abuse Correspondence

This article reports on forensic letters written by physicians specializing in identifying children who have experienced maltreatment. These writers face an extraordinary exigence in that they must provide an opinion as to whether a child has experienced abuse without specifically diagnosing abuse and thus crossing into a legal domain. Their credibility was also at issue because, in this jurisdiction, child abuse identification was not recognized as a medical subspecialty and because the status of expert witnesses is currently being challenged. Through an analysis of 72 forensic letters combined with interview data from six letter writers and five letter readers, we determined that these writers used linguistic and rhetorical strategies that allowed these letters to function as boundary objects or objects that traverse several communities of practice. The most salient strategy was the use of evaluative lexis—adjectives and adverbs which allowed for a range of interpretations and constrained those interpretations at the same time
