Comunicação corporativa na comunicação pública: estudo de notícias de assessorias de imprensa de universidades públicas paulistas

The purpose of this experimental project was to characterize the reports by the press offices of three public universities in São Paulo higher education, two state and one federal, evaluating what prerogatives of corporate communication are present in the public communication made by them. From the perspective of the content analysis proposed by Laurence Bardin and; based on the concepts involved in the definition of public communication by Pierre Zémor and Corporate Communications by Jorge Duarte, it was made an analysis of the method of construction of news from the three universities. It was used a methodology in which interspersed of quantitative analysis procedures with qualitative analysis procedures

Lei de Meios argentina: entre o velho e o novo na disputa pelo direito à comunicação

A pesquisa analisa o novo marco regulatório da comunicação da Argentina, a Lei n° 26.522/2009 de Serviços de Comunicação e Audiovisual (LSCA). O texto é referência reguladora emblemática e contemporânea para os campos de estudos da Comunicação, das Políticas Públicas e da Economia Política da Comunicação na América Latina. O caráter original dessa legislação reside na aproximação de uma concepção inovadora do direito à comunicação e na atribuição de um novo papel regulador reservado ao Estado. A criação de uma nova arquitetura institucional para o desenho das políticas de comunicação, o estabelecimento de limites de propriedade para empresas e grupos da radiodifusão e a divisão do espectro radioelétrico em partes iguais para operadores privados, estatais e privados sem fins de lucro são objetos de especial atenção. Nesse sentido, são analisadas as premissas normativas da LSCA e os obstáculos à sua implantação. O processo de elaboração e implantação dessa nova legislação é inseparável do momento político e da correlação de forças políticas do país e de um fenômeno comum na América Latina desde a redemocratização: a emergência da sociedade civil e a luta pela difusão dos direitos de cidadania. A pesquisa aponta tensões entre politicas públicas progressistas e velhos costumes impregnados no Estado, como o fortalecimento de grupos de mídia próximos ao governo de turno e o uso oficialista dos canais de comunicação estatais. Assim, a LSCA revela baixo grau de materialização, a despeito de representar um avanço normativo, institucional e político chave para o país e a região na perspectiva da democratização da comunicação

Comunicação pública e acesso à informação: análise da atuação da SABESP em plataformas virtuais

This undergraduate research final paper analyzed the communication process carried out by the São Paulo State Water and Sanitation Company - Sabesp from the perspective of public communication, social capital and right to information theories. By monitoring Sabesp's institutional fanpage and website from 24 to 30 August 2015, it sought to assess the performance of Sabesp in disclosing public information on the context of the water supply crisis in São Paulo, concerning the fulfillment of requirements of the Right to Information Law (12.527/2011) and the need for interaction and dialogue between the institution and its stakeholders, taken as principles of public communication. The results suggest that digital media can enhance information flow and contribute to foster public relations and civic participation, but there are opportunities for Sabesp to improve communication and reach greater transparency

GRAMMAR and COMMUNICATION IN PORTUGUESE AS A FOREIGN LANGUAGE A Study in the Context of Teletandem Interactions

This paper presents a study about the role of grammar in on-line interactions conducted in Portuguese and in English, between Brazilian and English-speaking interactants, with the aim of teaching Portuguese as a foreign language (PFL). The interactions occurred by means of chat and the MSN Messenger, and generated audio and video data for language analysis. Grammar is dealt with from two perspectives, an inductive and a deductive approach, so as to investigate the relevance of systematization of grammar rules in the process of learning PFL in teletandem interactions.

Breastfeeding knowledge and practice of health professionals in public health care services

Objetivou-se avaliar conhecimentos e práticas sobre aleitamento materno de profissionais que atendem lactentes em unidades de atenção básica, ou maternidades públicas, de município do interior paulista, Brasil. É estudo epidemiológico, sendo a população composta por 89 enfermeiros e médicos. Suas respostas a um questionário estruturado foram analisadas no total e segundo o local de trabalho, aplicando-se o teste de diferença de proporções (qui-quadrado), considerando-se p<0,05 como nível crítico. Como parâmetros de acertos foram consideradas as recomendações do Ministério da Saúde. As diferenças significativas para conhecimentos e práticas, segundo o local de trabalho, foram restritas a alguns aspectos, com resultados discretamente melhores dos escores médios de acertos dos profissionais das unidades de atenção básica. Independente do local de trabalho, verificou-se desempenho regular e ruim em diferentes aspectos estudados, indicando que possíveis intervenções para a capacitação nessa temática deverão incluir profissionais de todos os níveis de atenção à saúde.

Visual and acoustic communication in the Brazilian torrent frog, Hylodes asper (Anura : Leptodactylidae)

We studied the signaling, territorial, and courtship behaviors of the diurnal frog Hylodes asper. Visual and acoustic communication were used during intraspecific interactions involving males, females. and subadults. Hylodes aspcr has a complex visual communication system, of which foot-flagging is the most distinctive display observed in the repertoire of visual signals. The splash zone produced by the waterfalls and torrents creates a high, nearly constant, humidity near the streams, reducing the risk of desiccation which enables the diurnal activity of H. asper. Although the ambient sound pressure levels (SPL), measured at the calling sites, are similar to the SPL of the advertisement calls, the high-pitched calls of H, asper, are spectrally different from the noise produced by the water current. Thus. The ambient noise produced by the water current may not interfere significantly with the acoustic communication of this species. The noise and the nearly constant and high humidity produced by the torrents and waterfalls, along with the availability of Light, probably favored the evolution of contrasting colors and visual communication in H. asper: Males of H, aspcr excavate underwater chambers that are probably used to shelter the eggs and to prevent the clutch from being drifted downstream.

Modulation of intercellular communication in macrophages: possible interactions between GAP junctions and P2 receptors

Gap junctions are connexin-formed channels that play an important role in intercellular communication in most cell types. In the immune system, specifically in macrophages, the expression of connexins and the establishment of functional gap junctions are still controversial issues. Macrophages express P2X(7) receptors that, once activated by the binding of extracellular ATP, lead to the opening of transmembrane pores permeable to molecules of up to 900 Da. There is evidence suggesting an interplay between gap junctions and P2 receptors in different cell systems. Thus, we used ATP-sensitive and -insensitive J774.G8 macrophage cell lines to investigate this interplay. To study junctional communication in J774-macrophage-like cells, we assessed cell-to-cell communication by microinjecting Lucifer Yellow. Confluent cultures of ATP-sensitive J774 cells (ATP-s cells) are coupled, whereas ATP-insensitive J774 cells (ATP-i cells), derived by overexposing J774 cells to extracellular ATP until they do not display the phenomenon of ATP-induced permeabilization, are essentially uncoupled. Western-blot and reverse-transcription polymerase chain reaction assays revealed that ATP-s and ATP-i cells express connexin43 (Cx43), whereas only ATP-s cells express the P2X(7) receptor. Accordingly, ATP-i cells did not display any detectable ATP-induced current under whole-cell patch-clamp recordings. Using immunofluorescence microscopy, Cx43 reactivity was found at the cell surface and in regions of cell-cell contact of ATP-s cells, whereas, in ATP-i cells, Cx43 immunoreactivity was only present in cytosolic compartments. Using confocal microscopy, it is shown here that, in ATP-s cells as well as in peritoneal macrophages, Cx43 and P2X(7) receptors are co-localized to the membrane of ATP-s cells and peritoneal macrophages.

Visual communication in Brazilian species of anurans from the Atlantic forest

Visual communication is widespread among several anuran families, but seems to be more common than currently thought. We investigated and compared visual communication in six species of an anuran community in the Brazilian Atlantic forest. Four are nocturnal species: Hyalinobatrachium uranoscopum (Centrolenidae), Hyla albomarginata, Hyla sp. (aff. ehrhardti), and Scinax eurydice (Hylidae), and two are diurnal species: Hylodes phyllodes and Hylodes asper ( Leptodactylidae). For H. uranoscopum, H. albomarginata, S. eurydice, and H. phyllodes, this is the first record of visual communication. Observations were made at Nucleo Picinguaba, Parque Estadual da Serra do Mar, in the Municipality of Ubatuba, State of São Paulo, Brazil. Descriptions of behaviour were based on individuals observed in the field, using sequence sampling with continuous tape recording for behavioural observations. Eight new behaviours are described: body wiping, face wiping, jump display, leg kicking, limb lifting, mouth opening, toe flagging, and vocal sac display. of the 42 anuran species known from Nucleo Picinguaba, at least six ( approximately 14%) display visual communication. The evolution of visual signals in these species may be related to the availability of ambient light, the structural complexity of the habitat, and/or the ambient noise. They may also have evolved to aid in the location of the individual, to avoid physical combat, and/or may be a by-product of seismic communication.

Chemical communication in Apis mellifera: Temporal modulation of alarm behaviors

The effect of pheromones and their chemical analogues in honeybee alarm behaviors was studied in observation boxes. Defensive behaviors, as follows: a) attraction to scent source, b) elevation of wings in 'V', c) abdomen elevation, d) abdomen elevation and pumping and e) first leg pair elevation had been temporarily registered when the following compounds were presented: isoamyl alcohol, octyl alcohol, benzyl alcohol, n-butyl acetate, n-octyl acetate, isopentyl acetate, benzyl acetate and 2-heptanone. The results were as follows: 1. the bees elicited some characteristic behaviors when chemical alarm messages were presented, 2. agression (stinging) was not completed with any compound tested, probably because there was not a target (visual stimulus), 3. in all situations the attraction to scent source was low, 4. all the behaviors were elicited in a temporarily different way, 5. the compounds that elicited stronger responses and a greater number of the investigated behaviors were: isopentyl acetate, 2-heptanone, octyl acetate and n-octyl alcohol. In all situations, the first behavior response (and the most intense one) was the elevation and pumping the abdomen. This suggests that the chemical message was promptly recognized and then transmitted to each worker. So, the results obtained in the present work, suggest that chemical alarm messages may be recognized by different mechanisms of neural integration.

Short Communication: In vitro evaluation of the abrasiveness of acidic dentifrices.

AIM: This in vitro study evaluated the abrasiveness of acidic fluoride (F) dentifrices with different F concentrations on bovine enamel. METHODS: Enamel blocks (4.0 x 4.0 mm2, n=120) were selected according to their surface microhardness and divided into 12 groups. Slurries of dentifrices were used containing 0 (placebo), 275, 412, 550 and 1,100 ppm F (pH 4.5 or 7.0), as well as testing two commercial dentifrices (Crest, positive control, 1,100 ppm F and Colgate Baby, 500 ppm F). Enamel blocks were partially protected with an adhesive tape (control area) and then brushed by an automated toothbrushing machine (16,000 strokes). During this process, 0.4 ml of the slurries were injected every 2 mins on the enamel blocks. After toothbrushing, enamel wear was determined by profilometry. STATISTICS: Results were analyzed by ANOVA and Tukey's test (p<0.05). RESULTS: The mean values for pH in the suspensions during treatment were 6.93, 4.32, 7.56 and 8.19 for neutral experimental dentifrices, acidic experimental dentifrices, Crest and Colgate baby, respectively. The abrasiveness of the acidic dentifrices was similar (p<0.05) to the neutral ones, whereas commercial dentifrices yielded lower abrasion (p<0.05). CONCLUSION: It was concluded that a reduction of the pH of dentifrices does not increase their abrasiveness.

Fluoride concentration in public water supply: 72 months of analysis

Known as one of the ten most important advances on Public Health in the 20th century, fluoridation of public water supply is a measure of wide population coverage, which is effective on caries control. The city of Araçatuba, in the Northwest region of the São Paulo state, Brazil, started public water supply fluoridation in 1972 and, based on the average annual highest temperature, has kept the fluoride concentration between 0.6 to 0.8 mgF/L. The purpose of this study was to analyze monthly the fluoride concentration in public water supply in the city of Araçatuba during 72 months. Water samples were collected monthly on weekdays, directly from the water distribution network, on pre-established locations and analyzed in duplicate between November 2004 and October 2010 at the Research Laboratory of the Nucleus for Public Health (NEPESCO) of the Public Health Graduate Program from Araçatuba Dental School/UNESP, Brazil, using an fluoride-specific electrode connected to an ion analyzer. From the total of samples (n=591), 67.2% (n=397) presented fluoride concentration between 0.6 and 0.8 mgF/L; 20.6% (n=122) below 0.6 mgF/L; 11.5% (n=68) between 0.8 and 1.2 mgF/L and 0.7% (n=4) above 1.2 mgF/L. Most samples showed fluoride levels within the recommended parameters. Minimal variation was observed among the analyzed collection locations, showing that the city has been able to control the fluoride levels in the public water supply and reinforcing the importance of surveillance and constant monitoring to assure the quality of the water delivered to the population.
