The world-wide news agencies: development organization, competition, markets and product. A study of Agence France Presse, Associated Press, Reuters and United Press, to 1975

The thesis argues that in their development, organization and news services, the major western-based global news agencies have responded and continue to respond primarily to the requirements of western markets. In particular, their domestic markets are shown to be especially important to them, and much of their early development is explained by their struggle to secure monopolistic or oligopolistic control of these markets. The struggle to, achieve security in the domestic markets greatly tempered early international competition between the agencies in a way that still has consequences for their relative market positions in certain world regions, and which has hindered their penetration of one another's domestic markets. Nevertheless, growing international competition, general difficulties in traditional domestic newspaper markets and the evolution of new client requirements have combined to stimulate considerable market diversification in recent decades, both inside and outside media client groups. Within their traditional overseas markets, the global agencies, in their organization of news-gathering and news-distribution, have made considerable use of the national news agencies. The global agencies have stimulated the development of many such agencies, entering into relationships of unequal exchange with them, while only marginally threatened by the attempts of some national agencies to upset the dominant market position of their global partners. The thesis provides evidence of contemporary agency organization, news-gathering practices and news-service content in order to support the argument that there continues to exist a structural imbalance in agency operations which favours western market interests, and to further explore the underlying significance of their organizational priorities

As agências nacionais de notícias na turbulenta era da internet

Escrevendo recentemente, em 2000  (Boyd-Barrett, 2000), em continuidade a uma apresentação, em 1999, em Atenas, para a Aliança Europeia de Associações de Imprensa (mais tarde renomeada Aliança Europeia de Agências de Notícias), assinalei razões para uma preocupação sobre o papel e o futuro das agências de notícias.  [M1]Esta menção pode sair já que há a referência do escrito recente

Media Theory, Public Relevance and the Propaganda Model

Since its initial formulation in 1988, the Herman-Chomsky Propaganda Model (PM) has become one of the most widely tested models of media performance in the social sciences. This is largely due to the combined efforts of a loose group of international scholars as well as an increasing number of students who have produced studies in the US, UK, Canadian, Australian, Japanese, Chinese, German, and Dutch contexts, amongst others. Yet, the PM has also been marginalised in media and communication scholarship, largely due to the fact that the PM‟s radical scholarly outlook challenges the liberal and conservative underpinnings of mainstream schools of thought in capitalist democracies. This paper brings together, for the first time, leading scholars to discuss important questions pertaining to the PM‟s origins, public relevance, connections to other approaches within Communication Studies and Cultural Studies, applicability in the social media age, as well as impact and influence. The paper aligns with the 30th anniversary of the PM and the publication of the collected volume, The Propaganda Model Today, and highlights the PM‟s continued relevance at a time of unprecedented corporate consolidation of the media, extreme levels of inequality and class conflict as well as emergence of new forms of authoritarianism

Comments on the Sanef media audit: a new news culture is facing the media and journalism educators: the time to act is now!

This omnibus article deals with some of the comments received by the authors of the Sanef media audit (see p. 11) of the edition of Ecquid Novi). As Mark Deuze, one of the commentators puts it: The threats and challenges to contemporary journalism have caused scholars, publics, journalists, and thus journalism educators, to reconsider their approaches, definitions, roles, and function in community and society. Widely recognized as the four main changes or challenges facing education programmes in journalism are: the multicultural society; the rise and establishment of infotainment genres; the convergence of existing and new media technologies (cf. multimedia); and the internationalization or ‘glocalization’ of the media and journalism playing field. The four mentioned challenges and developments could be seen as reflected in the 2002 Sanef audit. The report particularly stresses the ‘new culture’ within which journalists are expected to do their work. This is a culture determined by fragmented audiences; a widening gap between journalists and their publics; and an increased need for quality information. It is also a culture of enhanced interactivity and media accountability; intercultural communication; recognition of cultural diversity; and dealing with ‘nonhierarchical’ management styles. Journalism education, in other words, is gearing up to face a tough challenge: keeping the best practices of the teaching context and practical skills courses on the one hand, and including cultural and critical reflective didactics on the other. This is not the traditional theory versus skills debate of old—this is definitely something ‘new’—as is clearly shown in the Sanef audit. In this respect the Sanef audit stands out for its discourse of emphasizing changes in journalism and news culture, rather than simply advocating more or less theory- or skills-based curricula

First observations of separated atmospheric nu_mu and bar{nu-mu} events in the MINOS detector

The complete 5.4 kton MINOS far detector has been taking data since the beginning of August 2003 at a depth of 2070 meters water-equivalent in the Soudan mine, Minnesota. This paper presents the first MINOS observations of nuµ and [overline nu ]µ charged-current atmospheric neutrino interactions based on an exposure of 418 days. The ratio of upward- to downward-going events in the data is compared to the Monte Carlo expectation in the absence of neutrino oscillations, giving Rup/downdata/Rup/downMC=0.62-0.14+0.19(stat.)±0.02(sys.). An extended maximum likelihood analysis of the observed L/E distributions excludes the null hypothesis of no neutrino oscillations at the 98% confidence level. Using the curvature of the observed muons in the 1.3 T MINOS magnetic field nuµ and [overline nu ]µ interactions are separated. The ratio of [overline nu ]µ to nuµ events in the data is compared to the Monte Carlo expectation assuming neutrinos and antineutrinos oscillate in the same manner, giving R[overline nu ][sub mu]/nu[sub mu]data/R[overline nu ][sub mu]/nu[sub mu]MC=0.96-0.27+0.38(stat.)±0.15(sys.), where the errors are the statistical and systematic uncertainties. Although the statistics are limited, this is the first direct observation of atmospheric neutrino interactions separately for nuµ and [overline nu ]µ

A brief explanation and overview of constitutivism

Philosophy of action

The philosophical study of human action begins with Plato and Aristotle. Their influence in late antiquity and the Middle Ages yielded sophisticated theories of action and motivation, notably in the works of Augustine and Aquinas.1 But the ideas that were dominant in 1945 have their roots in the early modern period, when advances in physics and mathematics reshaped philosophy

The impact of viral mutations on recognition by SARS-CoV-2 specific T cells.

We identify amino acid variants within dominant SARS-CoV-2 T cell epitopes by interrogating global sequence data. Several variants within nucleocapsid and ORF3a epitopes have arisen independently in multiple lineages and result in loss of recognition by epitope-specific T cells assessed by IFN-γ and cytotoxic killing assays. Complete loss of T cell responsiveness was seen due to Q213K in the A∗01:01-restricted CD8+ ORF3a epitope FTSDYYQLY207-215; due to P13L, P13S, and P13T in the B∗27:05-restricted CD8+ nucleocapsid epitope QRNAPRITF9-17; and due to T362I and P365S in the A∗03:01/A∗11:01-restricted CD8+ nucleocapsid epitope KTFPPTEPK361-369. CD8+ T cell lines unable to recognize variant epitopes have diverse T cell receptor repertoires. These data demonstrate the potential for T cell evasion and highlight the need for ongoing surveillance for variants capable of escaping T cell as well as humoral immunity.This work is supported by the UK Medical Research Council (MRC); Chinese Academy of Medical Sciences(CAMS) Innovation Fund for Medical Sciences (CIFMS), China; National Institute for Health Research (NIHR)Oxford Biomedical Research Centre, and UK Researchand Innovation (UKRI)/NIHR through the UK Coro-navirus Immunology Consortium (UK-CIC).
