Somos quem podemos ser - agonística e identidade do jornalista contemporâneo.

Journalist O Jornalismo como atividade social produtiva é atingido, na contemporaneidade, por crises de sentido, em um cenário de conflitos e questionamentos da identidade profissional. A tese defendida neste estudo é a de que identidade profissional do jornalista compõe, atualmente, um ethos agônico, pressionado por crises estruturais e conjunturais de desinstitucionalização e deslegitimação. Em relação ao passado recente de afirmação essencialista e profissionalização, a identidade do jornalista se produz de encontro a demandas externas, no encontro com a heteroidentidade. Problematiza-se a relação entre o fator agônico estrutural da identidade do jornalista e processos de deslegitimação e de não reconhecimento, perguntando em que medida o agonismo mantém aberta a profissão. A abordagem é cartográfica, estudando os vetores críticos e (des)legitimantes operantes nas enunciações sobre a identidade do jornalista em dados coletados a partir de João Pessoa (PB). Para efeito de análise, o campo empírico foi abordado por gerações profissionais, tomando como fontes informadoras jornalistas que adentraram a profissão nos últimos quarenta anos, da década de 1970 até 2012. Além da colaboração de jornalistas em questionários autoaplicados, coletamos dados junto aos presidentes do Sindicato dos Jornalistas Profissionais do Estado da Paraíba e do Sindicato Patronal, a partir de entrevistas não estruturadas. Para refletir sobre a questão proposta na pesquisa, são referenciados pensadores que analisaram conceitos de crise e conflito, teorias da identidade e sociologia das profissões, visando uma síntese de agonismos da profissão, no sentido de localizar ordens estruturais e conjunturais de legitimação e deslegitimação, valores e relações que constituem a identidade profissional do jornalista.Journalism as social productive activity is reached, in contemporaneity, by crises of meaning, in a scenario of conflicts and questions of professional identity. The thesis defended in this study is that professional identity consists journalist, at present, a agonal ethos, pressured by structural and conjunctural crises of deinstitutionalization and delegitimization. In connexion with the recent past essentialist affirmation and professionalism, the identity of the journalist is produced against external demands, the encounter with heteroidentity. Problematizes the relationship between the structural factor agonal identity of the journalist and processes of delegitimization and nonrecognition, wondering to what extent agonism holds open the profession. The approach is cartographic, studying the critical and (de)legitimizing vectors the operating in utterances about the identity of the journalist on data collected from João Pessoa (PB). For purposes of analysis, the empirical field was approached by professionals generations, taking as informants sources journalists that entered the profession in the last forty years, from the 1970s until 2012. Further the collaboration of professionals in selfadministered questionnaires, we collect data from the presidents of the Sindicato of dos Jornalistas Profissionais do Estado da Paraíba and Patronal Syndicate, per unstructured interviews. To reflect on the question posed in the research, are referenced thinkers that analyzed concepts of crisis and conflict, theories of identity and sociology of professions, aiming at a synthesis of profession’s agonisms, in order to locate structural and conjunctural orders of legitimation and delegitimation are referenced, values and relationships that constitute the professional identity of the journalist

Safety and efficacy of the ChAdOx1 nCoV-19 vaccine (AZD1222) against SARS-CoV-2: an interim analysis of four randomised controlled trials in Brazil, South Africa, and the UK.

BACKGROUND: A safe and efficacious vaccine against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), if deployed with high coverage, could contribute to the control of the COVID-19 pandemic. We evaluated the safety and efficacy of the ChAdOx1 nCoV-19 vaccine in a pooled interim analysis of four trials. METHODS: This analysis includes data from four ongoing blinded, randomised, controlled trials done across the UK, Brazil, and South Africa. Participants aged 18 years and older were randomly assigned (1:1) to ChAdOx1 nCoV-19 vaccine or control (meningococcal group A, C, W, and Y conjugate vaccine or saline). Participants in the ChAdOx1 nCoV-19 group received two doses containing 5 × 1010 viral particles (standard dose; SD/SD cohort); a subset in the UK trial received a half dose as their first dose (low dose) and a standard dose as their second dose (LD/SD cohort). The primary efficacy analysis included symptomatic COVID-19 in seronegative participants with a nucleic acid amplification test-positive swab more than 14 days after a second dose of vaccine. Participants were analysed according to treatment received, with data cutoff on Nov 4, 2020. Vaccine efficacy was calculated as 1 - relative risk derived from a robust Poisson regression model adjusted for age. Studies are registered at ISRCTN89951424 and ClinicalTrials.gov, NCT04324606, NCT04400838, and NCT04444674. FINDINGS: Between April 23 and Nov 4, 2020, 23 848 participants were enrolled and 11 636 participants (7548 in the UK, 4088 in Brazil) were included in the interim primary efficacy analysis. In participants who received two standard doses, vaccine efficacy was 62·1% (95% CI 41·0-75·7; 27 [0·6%] of 4440 in the ChAdOx1 nCoV-19 group vs71 [1·6%] of 4455 in the control group) and in participants who received a low dose followed by a standard dose, efficacy was 90·0% (67·4-97·0; three [0·2%] of 1367 vs 30 [2·2%] of 1374; pinteraction=0·010). Overall vaccine efficacy across both groups was 70·4% (95·8% CI 54·8-80·6; 30 [0·5%] of 5807 vs 101 [1·7%] of 5829). From 21 days after the first dose, there were ten cases hospitalised for COVID-19, all in the control arm; two were classified as severe COVID-19, including one death. There were 74 341 person-months of safety follow-up (median 3·4 months, IQR 1·3-4·8): 175 severe adverse events occurred in 168 participants, 84 events in the ChAdOx1 nCoV-19 group and 91 in the control group. Three events were classified as possibly related to a vaccine: one in the ChAdOx1 nCoV-19 group, one in the control group, and one in a participant who remains masked to group allocation. INTERPRETATION: ChAdOx1 nCoV-19 has an acceptable safety profile and has been found to be efficacious against symptomatic COVID-19 in this interim analysis of ongoing clinical trials.

Telejornalismo em plataformas interativas

No mundo em rede, analisar possibilidades de práticas de telejornalismo digital em plataformas interativas se constitui numa tentativa de revisitar as práticas, funções e identidades profissionais em contexto de convergência midiática. No foco colaborativo da interação, emergem práticas jornalísticas com marcas open-source, demandando revisões nos modos de endereçamento a partir de novas plataformas que torna cada vez mais complexa a práxis cotidiana. Assim, o telejornalismo evolui deixando os ensaios transpositivos em função de exercícios de deslocamentos que se dão através de processos de hibridação, incorporando as características dos meios digitais interativos e da cultura das redes
