Tony Blair's 'Media' Speech: The Commentators

Tony Blair's speech challenged the media over its standards in his valedictory lecture. Many of his charges about the absence of balance, attacks on motive and a pack mentality stand up, even if some are exaggerated and also applied well before his arrival in 10 Downing Street. Mr Blair's solutions did ot match his critique. What is required is a more self‐questioning media, being held to account on the internet and on specialist blogging sites. Vigorous criticism, requiring justification, is a more credible rout than tighter regulation. Tony Blair's speech on the changing pressures on the media is both interesting and convincing in its diagnosis (although generally reported in ways that did not reveal this). It is less convincing in suggestions for change: the fact that on‐line media will fall under Of‐com, and so under its minimal ‘content regulation’ will have little impact. Effective change could begin with other types of (self or other regulation). Some steps towards change might include minimal requirements for journalists and editors to accept elementary forms of accountability, such as disclosing conflicts of interest and payments made for ‘stories’. The scale of media coverage may be crucial in determining the allocation of aid, yet the attention the media pays to particular causes is arbitrary. Many serious disasters are not reported and as a consequence do not receive adequate aid, so that the victims of the crisis will lose out. Chronic long term problems, like famine, are ignored in favour of ‘sudden emergencies’. Reporting seeks sensation and simple stories which influences the way that aid agencies respond to the media. The complex background to a faraway disaster is often overlooked and not properly reported. Tony Blair's speech describing some of the news media as ‘feral beasts’ contained one paragraph which contained an insight into his views on new media. It was known that the outgoing Prime Minister was uncomfortable with some aspects of new technology but his remarks reveal a wider disappointment with how new media has failed to deliver changes which he had hoped for in political communications.This paper records Mr Blair's problems with new media and argues that by focusing on how the new technologies might provide a better way for politicians to by‐pass the traditional media he has missed the point of their wider benefits.     

Guest editor's introduction

In 1933 the army of the nascent Iraqi state launched an exterminatory attack on members of the Assyrian community who had fled to Iraq during the First World War. 'The Assyrian affair' which at the time sent shock-waves around the world has now been largely forgotten. But an examination of its origins and causation reveals much about the nature and pattern of modern genocide. Levene argues that typecasting genocide as the outcome of prejudice, racism or even xenophobia, while these may be significant ingredients, proves to be insufficient as a comprehensive explanation. Rather, these factors need to be analysed within the context of an emerging international system of nation-states. This itself may be a factor in helping to catalyse the most extreme and radically ideological responses, especially from new and untried national elites seeking to overcome perceived obstacles to their state's development and genuine independence.     

Ethnic and religious variations in the reporting of racist victimization in Britain: 2000 and 2008/2009

The role of victimization in the generation of ethnic inequalities is increasingly acknowledged yet its impact on the lives of people with different religious affiliations remains underexplored. This is despite evidence of the importance of religion for forms of group identification and social mobilization. An exploration of the particular impact of religion as a focus for experiences of victimization may be particularly pertinent given the increasingly negative treatment of Muslim people since the riots in Britain of 2001, the terrorist incidents of 2001, 2004 and 2005 and the political and military responses to them. Cross-sectional analyses of data collected in 2000 and 2008/2009 explore whether there is evidence that the ethnic/religious patterning of reports of different forms of victimization have varied over time, after adjusting for the impact of age, gender, migration and socioeconomic differences between the groups. In 2000 Muslim people with different ethnic backgrounds were less likely, but by 2008/2009 were more likely, to report experiences of victimization than Caribbean Christians. However, the ethnic/religious patterning of perceptions of Britain as a ‘racist society’ were more consistent over time. This may suggest that, despite their increased exposure to victimization over the period, Muslim people in the United Kingdom have yet to experience the racialization characteristic of the treatment of Caribbean Christians, which requires a more prolonged exposure to racist negative attitudes. But this may be only a matter of time. The persistent expectation of poor treatment described by Caribbean Christians is testament to the difficulties of addressing these negative perceptions once racialized identities are embedded. Immediate action must be taken to prevent this occurring among other ethnic/religious minorities.     

The Strange Career of British Democracy: John Milton to Gordon Brown

Political debate in modern Britain has been structured by four narratives or traditions, called here ‘Whig imperialist’, ‘Tory nationalist’, ‘democratic collectivist’ and ‘democratic republican’. The Whig imperialist tradition goes back to Edmund Burke; it is a tradition of responsive evolution, flexible statecraft, genial optimism and abhorrence of dogmatic absolutes. It prevailed for most of the nineteenth century, for most of the interwar period and for most of the 1950s and early‐1960s. Its Tory nationalist counterpart is tense, rebarbative and often shrill. At its core lies a primal fear of the dissolution of authority and a collapse of the social order. Its most notable exponents include Lord Salisbury, Enoch Powell and Margaret Thatcher. The democratic collectivist tradition stresses ineluctable progress towards a just and rational society, to be achieved by a strong, essentially technocratic central state, with the power and will to replace the wasteful, unjust chaos of the market place by planned co‐ordination. Formative influences on it were the great Fabian socialists, George Bernard Shaw and Sidney and Beatrice Webb; it achieved its apotheosis under the Attlee Government of 1945‐51. The democratic republican tradition is much more inchoate: its exponents have been the awkward squad of British democracy. The most glittering stars in the democratic republican firmament were probably John Milton, John Stuart Mill and R.H. Tawney. It stresses active self‐government and republican self respect, embodied in a vigorous civil society and strong local authorities. During the ninety‐odd years since Britain belatedly acquired a more‐or‐less democratic suffrage, the first three traditions have all been tested, almost to destruction. But though the fourth has had great influence on social movements of all kinds, governments at the centre have done little more than toy with it, usually for brief periods. The great question now is whether Britain is about to experience a democratic republican moment.     

The Sacred,Social Creativity and the State

Abstract

This paper explores the specific contribution of a strand of contemporary French social theory founded by Cornelius Castoriadis and Claude Lefort to the under standing of human power. It formulates a conception of power that transcends its definitions in terms of physical coercion or institutionalised violence to reveal the way power is creative and institutes the social. Its reflection on the cultural nature of political power and it role in society is shown to extend the pioneering reflection of Durkheim's sociology, especially as regards the homology that exists between religion and politics. The social role performed by the state explored by Durkheim prefigures Gauchet's theory of the state, which builds on Lefort's work. Gauchet's theory can be said to elaborate a critical synthesis of the two stands of Durkheim's work: the sociology of religion and the sociology of the modern state. This synthesis raises questions on the role played by the European state in the development of individualism, in both its political and economic manifestations.     

The Role of the Maternal in Diasporic Cultural Reproduction−Australia,Canada and Greece

Cultural reproduction is examined in this paper, not in the sense of replication, but as the creation of something new. Women's work in such cultural reproduction is explored through the experiences of Greek-identified women who live in Canada and Australia, or who have lived in these countries and now reside in Greece. These women are the daughters of immigrants who are now rearing the so-called third generation. Of particular interest is the way these women contrast their role in cultural reproduction to that of their own mothers. The argument is made that these women play a key role in the staging of Greek origin through the family and that, in the diaspora, this is a complex, dynamic and critical process that lies at the heart of new understandings of cultural identifications.     

The Language of Race

The 1991 Census form for households in Great Britain included, for the first time, a question about ethnic group. The question had nine boxes, eight for named ethnic groups and one for 'any other'. One box had to be ticked for each member of the household. Brian Klug discusses his own reaction to the (so-called) ethnic question, and explains why, as a Jew of European extraction, he did not tick the box marked White. He examines several issues raised by the ethnic question, including the following: why this question is different from other questions on the form; the definition and use of the words 'racial' and 'ethnic'; the vocabulary of colour ('black', 'white' etc.) in the language of race; the idea that 'white' is an ethnic category; the claim that the ethnic question is an instrument for combatting racism; one proposal for improving the question by removing the 'racial' components in the categories.     

Trustworthiness: the Commentators

Mark Thompson deplores the decline in the public trust of government and of public service institutions such as the BBC. But there has also been a decline in another form of trust: government's trust in the ability of professionals such as doctors and teachers to deliver high quality public services. And, unlike Thompson's type of trust, this decline was inevitable, because it was based on untenable assumptions concerning professional motivation. The author discusses the importance of trust in an unwritten constitution, including trust in the use made of public resources, trust that appointments are being made on merit, trust that the civil service is ‘speaking truth unto power’ behind the scenes and ultimately trust that it retains the ability to serve future governments. In a world where trust in institutions is diminishing, there are still surprising levels of trust in the world of private philanthropy. The public are only too ready to give donations without seeking to question, especially in the wake of major disasters. Yet the nature of aid agencies has changed dramatically in the past thirty years into major global enterprises with sophisticated media and marketing operations. In this case a greater degree of scepticism from those who donate and paradoxically less trust might actually result in better outcomes from aid and better use of funding. Trust is critical to the mission of the FCO. The public needs to trust the competence and sound judgment of the professional diplomats. The diplomats themselves need to be able to rely on the commonsense of their fellow colleagues. Ministers and diplomats need to trust each other. And other governments need to have confidence in the discretion of their British counterparts. This is an increasing challenge in the world of instant news. Trust can be quickly lost by indiscreet or self‐serving revelations. But the key is to be as open and transparent as possible about the processes of diplomacy. A new survey commissioned by the British Journalism Review demonstrates that public confidence in journalism has collapsed over the last five years. This is particularly true for the commercial broadcasters ITV and Channel 4, whose journalism has traditionally commanded as much public esteem as the BBC. Trust in the BBC and print journalists has also declined, and journalism suffered more than any of the other 16 occupational groups being assessed. This is partly due to the cumulative effect of various “fakery” scandals that have afflicted broadcasters over the last 18 months and partly down to a more widespread cynicism directed at those in authority.     

Last Thoughts on <Emphasis Type="Italic">The Last Intellectuals</Emphasis>

Over twenty years ago my book The Last Intellectuals put into circulation the phrase “public intellectual.” The term unexpectedly enjoyed great success. It encapsulated a new division between a professional or academic intellectual focused on his or her specialty and an intellectual orientated to a larger public. The former tend to disappear into the university, while they latter write for the educated public. In the twenty years since its publication, my book has been sharply challenged. Moreover the emergence of African-American and women intellectuals, and well as new developments such as Internet, have possibly undermined my thesis. Yet these phenomena amount to revisions, not refutations, of my thesis. Moreover the role of intellectuals in France and Germany suggest that the same process of academization is taking place in other advanced industrial nations. What is called for is not nostalgia or its opposite, a celebration of everything that happens, but a consideration of the real shifts that affect the lives and work of intellectuals.

Emerging regional security co‐operation in Europe and the Asia Pacific

European and Asian‐Pacific policymakers need to shift from policies based on competition to those based on co‐operation. If European and Asian‐Pacific states are successful in implementing and strengthening new security institutions on the basis of co‐operative behaviour designed to realize absolute gains, then conflict in these two regions may decrease and regional hegemonic competition may not materialize. It is argued that three key factors will determine the viability of any regional security framework. These are reciprocity in security relations, great power support for the security arrangements and reassurance. In this study's comparative evaluation of Europe and the Asia Pacific, the pursuit of absolute gains through a security regime appears to be a better alternative to relative gains strategies which serve to intensify security dilemmas.

In Europe, rules and norms for state behaviour are being extended throughout the continent through the gradual extension of the West European security institutions to Central and East European states. The NACC and the PfP offer to combine the stability of the North Atlantic Alliance with the principles of co‐operative security at a pan‐European level. In the Asia Pacific, the ASEAN Regional Forum represents a positive initial step towards greater security co‐operation among the ASEAN states and their neighbours, and the United States and China need to give the ARF their full support. The difference between the ARF and NACC and the PfP is that the former does not have a history of successful military collaboration behind it, nor a developed security agenda or structure similar to that now supporting the latter two.     

'Shovelling out your paupers': The British State and Irish Famine Migration 1846-50

Gray considers the determinants of British policy towards emigration (and particularly towards state-assisted 'colonization') from Ireland during the Great Famine of 184-50. He surveys the idea of 'colonization' as advocated by Charles Buller in 1843, and its varying appeal (changing over time) in Ireland, Britain and the settlement colonies of the British empire. He also considers the issue in the light of pro- and anti-Malthusian interpretations of Irish population pressure, and the emergence of the alternative idea of 'internal colonization'. Gray argues that the failure of the state to adopt an emigration policy in 1846-50 as part of its response to the Famine was the consequence of a combination of anti-Irish prejudice in Britain and the colonies (which was sharpened by the arrival of large numbers of economic refugees in 1847 and the political conspiracies of 1848), and the prevalence of an economic doctrine that prioritized the need for Irish self-help and moral transformation over state assistance. He traces the debate over colonization within the Whig government headed by Lord John Russell, and concludes that some form of assisted emigration was a feasible policy measure, and that its rejection had adverse consequences in terms of additional famine mortality.
