Comunicação, cultura e linguagem

Os artigos apresentados neste volume da coleção “Desafios Contemporâneos” têm como objetivo refletir sobre os problemas atuais que marcam o diálogo com o campo acadêmico e científico da Comunicação. Os 18 artigos reunidos aqui contemplam a área de Comunicação e envolvem diferentes linhas de pesquisa. A iniciativa teve como fim expor não apenas as discussões gerais sobre o campo, mas também a experiência singular e atuante dos pesquisadores da Unesp dedicados ao estudo da Comunicação. Três eixos nortearam a organização dos artigos. O primeiro, “Múltiplas formas de linguagem e produção de sentido”, reúne textos que investigam o campo da produção, da circulação e do funcionamento e das estruturas da linguagem nas diversas mídias e nas suas tipologias textuais. “Políticas e estratégias da Comunicação” trata dos processos e fluxos de comunicação no mundo atual e sua relação com a política na sociedade. Já o terceiro eixo, “Relações socioculturais e suas manifestações na esfera da indústria cultural e das mídias digitais”, analisa as dimensões dos processos, da difusão e da recepção dos produtos midiáticos em sua relação sociocultural. Entre os temas abordados estão a comparação entre as linguagens jornalística e publicitária, a censura judicial à liberdade de imprensa, o desafio teórico-metodológico na aplicação da antropologia interpretativa ao campo da comunicação, conjunturas e desafios da educação superior em comunicação no Brasil, a focalização da vida operária no cinema de Leon Hirszman pelo filme Eles não usam black-tie, entre outros.

Available nitrogen and responses to nitrogen fertilizer in brazilian eucalypt plantations on soils of contrasting texture

Eucalyptus plantations have seldom responded to N fertilization in tropical and subtropical regions of Brazil. This implies that rates of N mineralization have been adequate to supply tree needs. However, subsequent crop rotations with low N fertilization may result in declining concentrations of organic and potentially mineralizable N (N-0), and consequent loss of wood productivity. This study investigated (a) in situ N mineralization and N-0 in soils of eucalypt plantations in Sao Paulo state, Brazil; (b) tree growth responses to N fertilizer applied 6-18 months after planting; and (c) the relationships between N-0,N- other soil attributes and tree growth. We established eleven N fertilizer trials (maximum 240 kg ha(-1) of N) in E. grandis and E. grandis x urophylla plantations. The soil types at most sites were Oxisols and Quartzipsamments, with a range of organic matter (18 to 55 g kg(-1)) and clay contents (8% to 67%) in the 0-20 cm layer. Concentrations of N-0 were measured using anaerobic incubation on soil samples collected every three months (different seasons). The samples collected in spring and summer had N-0 140-400 kg ha(-1) (10%-19% total soil N), which were best correlated with soil texture and organic matter content. Rates of in situ net N mineralization (0-20 cm) ranged from 100 to 200 kg ha(-1) year(-1) and were not correlated with clay, total N, or N-0. These high N mineralization rates resulted in a low response to N fertilizer application during the early ages of stand growth, which were highest on sandy soils. At the end of the crop rotation, the response to N fertilizer was negligible and non-significant at all sites.

Structure of copper complexes adsorbed on a silica gel surface chemically modified with benzimidazole

Silica gel having a particle size between 0.2 and 0.05 mm and a specific surface area, S BET = 473 m 2 g -1, was chemically modified with benzimidazole. Adsorption isotherms of CuX 2 (X = Cl, Br or ClO 4) from ethanol and acetone solutions were studied at 298 K. The metal is bonded to the surface through the free nitrogen atom of the attached benzimidazole. The average number of ligands co-ordinated to the central metal ion was shown to depend on the solid surface loading by the solute. At low loading the electronic and ESR spectral parameters indicated that the copper ion is in a distorted-tetragonal symmetry field.

Composições contendo o isolado jab 68 do fungo entomopatogênico metarhizium anisopliae e uso das composições

Essa invenção se refere ao desenvolvimento de composições com o isolado jab 68 do fungo entomopatogânico metarhizium anisopliae, em peletes de alginato de sádio, e em óleo emulsionável e pó molhável. As composições propostas são usadas no controle da mosca-dos-chifres. As composições em óleo emulsionável e pó molhável também podem ser usadas para o controle do carrapato de bovinos rhipicephalus (boophilus) microplus ou do carrapato de cães rhipicephalus sanguineus e para controle da cigarrinha da folha (mahanarva posticata) e da raiz (mahanarva fimbriolata) da cana-de-açúcar e das pastagens (deois flavopicta).

Problemas ergonômicos enfrentados por profissionais de enfermagem em ambientes hospitalares: aspectos da interface trabalhadores x equipamentos

The ergonomic design seeks to establish parameters to improve the interface between the technologies (products, systems and environments) and between man (users). Among the many factors involved, there are the activities performed in hospital settings, both by patients and by clinical staff. Accordingly, efforts have been demonstrated biomechanical with a leading occupational problem, especially regarding the transfer of patients.

Efeito de diferentes herbicidas, doses e volume de calda na dessecação de milheto [Pennisetum glaucum (L. Leek)]

The objective of this work was to evaluate the efficacy of different herbicides applied in post-emergence in the desiccation of pearl millet with different doses and spray volumes. For the desiccation, doses at 0, 25, 50 and 100% of the herbicide glyphosate (1,440 g ha-1) were used in 3 formulations (Original Round up, Round up Transorb and Round up WG), paraquat + diuron (500 + 250 g ha-1) and glufosinateammonium (800 g ha-1). In all treatments, 2 spray volumes (200 and 400 l ha-1) were used, and there was 1 treatment (control) without the application of herbicides. The treatment effects were evaluated visually at 3, 7, 14, 21 and 28 days after application (DAA). At the end of the evaluations, the dry mass of the plants was determined. The field trial was carried out in randomized block design. At the end of the study, at 28 DAA, all treatments presented total control of plant pearl millet, regardless of the dose and spray volume, except the treatments with paraquat + diuron and glufosinate-ammonium at the lower dose (25%), in 2 spray volumes, which nevertheless showed good and very good control, these two herbicides presenting an effect of volume, in which the control was higher with the use of smaller volume.

Behavior problems and prevalence of asthma symptoms among Brazilian children

Objective: Asthma is the most common chronic disease in childhood and has been designated a public health problem due to the increase in its prevalence in recent decades, the amount of health service expenditure it absorbs and an absence of consensus about its etiology. The relationships among psychosocial factors and the occurrence, symptomatology, and severity of asthma have recently been considered. There is still controversy about the association between asthma and a child`s mental health, since the pathways through which this relationship is established are complex and not well researched. This study aims to investigate whether behavior problems are associated with the prevalence of asthma symptoms in a large urban center in Latin America. Methods: It is a cross-section study of 869 children between 6 and 12 years old, residents of Salvador, Brazil. The International Study of Allergy and Asthma in Childhood (ISAAC) instrument was used to evaluate prevalence of asthma symptoms. The Child Behavior Checklist (CBCL) was employed to evaluate behavioral problems. Results: 19.26% (n = 212) of the children presented symptoms of asthma. 35% were classified as having clinical behavioral problems. Poisson`s robust regression model demonstrated a statistically significant association between the presence of behavioral problems and asthma symptoms occurrence (PR: 1.43; 95% Cl: 1.10-1.85). Conclusion: These results suggest an association between behavioral problems and pediatric asthma, and support the inclusion of mental health care in the provision of services for asthma morbidity.
