Using ancillary statistics in on-line learning algorithms

Neural networks are usually curved statistical models. They do not have finite dimensional sufficient statistics, so on-line learning on the model itself inevitably loses information. In this paper we propose a new scheme for training curved models, inspired by the ideas of ancillary statistics and adaptive critics. At each point estimate an auxiliary flat model (exponential family) is built to locally accommodate both the usual statistic (tangent to the model) and an ancillary statistic (normal to the model). The auxiliary model plays a role in determining credit assignment analogous to that played by an adaptive critic in solving temporal problems. The method is illustrated with the Cauchy model and the algorithm is proved to be asymptotically efficient.

La generación del silencio (II). El éxodo del Mariel, 25 años después:un acercamiento a los escritores e intelectuales que abandonaron la Isla para ejercer la creación artística y la libertad de expresión

El éxodo del Mariel, 25 años después: Aunque el público y la crítica de EE UU no fueron muy receptivos con la obra literaria de los marielitos, esa situación no frenó sus ambiciones. The Mariel boatlift, 25 years later: Although the public and critics of the U.S. were not very receptive to the literary work of Mariel, that situation did not stop his ambitions.

The individual and society in the GDR under Honecker : orthodoxy, dissidence and internal debate.

The thesis offers a comparative interdisciplinary approach to the examination of the intellectual debates about the relationship between individual and society in the GDR under Honecker. It shows that there was not only a continuum of debate between the academic disciplines, but also from the radical critics of the GDR leadership such as Robert Havemann, Rudolf Bahro and Stefan Heym through the social scientists, literary critics and legal theorists working in the academic institutions to theorists close to the GDR leadership. It also shows that the official line and policy of the ruling party itself on the question of the individual and society was not static over the period, but changed in response to internal and external pressures. Over the period 1971 - 1989 greater emphasis was placed by many intellectuals on the individual, his needs and interests. It was increasingly recognised that conflicts could exist between the individual and society in GDR socialism. Whereas the radical critics argued that these conflicts were due to features of GDR society, such as the hierarchical system of labour functions and bureaucracy, and extrapolated from this a general conflict between the political leadership and population, orthodox critics argued that conflicts existed between a specific individual and society and were largely due to external and historical factors. The internal critics also pointed to the social phenomena which were detrimental to the individual's development in the GDR, but they put forward less radical solutions. With the exception of a few radical young writers, all theorists studied in this thesis gave precedence to social interests over individual interests and so did not advocate a return to `individualistic' positions. The continuity of sometimes quite controversial discussions in the GDR academic journals and the flexibility of the official line and policy suggests that it is inappropriate to refer to GDR society under Honecker simply as totalitarian, although it did have some totalitarian features. What the thesis demonstrates is the existence of `Teiloffentlichkeiten' in which critical discussion is conducted even as the official, orthodox line is given out for public consumption in the high-circulation media.

Reacting and responding in TESOL Quarterly:a generic analysis of procedure and purpose in intertextual critical exchanges

A key feature of ‘TESOL Quarterly’, a leading journal in the world of TESOL/applied linguistics, is its ‘Forum’ section which invites ‘responses and rebuttals’ from readers to any of its articles. These ‘responses or rebuttals’ form the focus of this research. In the interchanges between readers reacting to earlier research articles in TESOL Quarterly and authors responding to the said reaction I – examine the texts for evidence of genre-driven structure, whether shared between both ‘reaction’ and ‘response’ sections, or peculiar to each section, and attempt to determine the precise nature of the intended communicative purpose in particular and the implications for academic debate in general. The intended contribution of this thesis is to provide an analysis of how authors of research articles and their critics pursue their efforts beyond the research article which precipitated these exchanges in order to be recognized by their discourse community as, in the terminology of Swales (1981:51), ‘Primary Knowers’. Awareness of any principled generic process identified in this thesis may be of significance to practitioners in the applied linguistics community in their quest to establish academic reputation and in their pursuit of professional development. These findings may also be of use in triggering productive community discussion as a result of the questions they raise concerning the present nature of academic debate. Looking beyond the construction and status of the texts themselves, I inquire into the kind of ideational and social organization such exchanges keep in place and examine an alternative view of interaction. This study breaks new ground in two major ways. To the best of my knowledge, it is the first exploration of a bipartite, intertextual structure laying claim to genre status. Secondly, in its recourse to the comments of the writers’ themselves rather than relying exclusively on the evidence of their texts, as is the case with most studies of genre, this thesis offers an expanded opportunity to discuss perhaps the most interesting aspects of genre analysis – the light it throws on social ends and the role of genre in determining the nature of current academic debate as it here emerges.

Androiden und (Anti)feminismus in The Stepford Wives

Since the early days of cinema the creation of artificial life with its various implications has been a popular topic on screen. Amongst the large number of films that deal with the theme of androids Bryan Forbes’ "The Stepford Wives" (1975) is noticeable for its focus on questions of gender and the relationship between the sexes. The film is set in a contemporary small suburban town where frustrated husbands have found a special way of dealing with their emancipated wives by replacing them with docile life-like robots. Mixing elements of the thriller and horror genres with farce and comedy "The Stepford Wives" was the first American mainstream film to deal explicitly with Women’s Lib. Unlike Ira Levin in his much more ambivalent novel that the film was based on, Forbes and his actors deliberately set out to make a feminist satire, and according to some critics succeeded in producing an important document of second wave feminism which soon acquired cult status. However, it also provoked a number of negative reactions from feminists who were very uncomfortable with a film in which men get away with murdering the female population of an entire town. A closer inspection reveals that the satirical element of the film is indeed not prominent and frequently counteracted, at times facilitating a misogynist rather than a feminist interpretation. This is mainly due to the ending of the film which implies the murderous elimination of the female protagonist. Unlike all other cinematic and literary works that feature androids "The Stepford Wives" shows the successful creation of artificial life which does not backfire. In addition, the film which clearly categorises itself as a thriller and horror movie, and specifically alludes to the tradition of threatened yet strong female characters in these genres, at the same time defies this convention in favour of a seemingly misogynist ending. Thus the way in which "The Stepford Wives" refuses to comply with the traditions of both the android theme and the horror genre, involuntarily serves to undermine its intention as a feminist social satire.

Introduction: the media, animal conservation and environmental education

Natural History filmmaking has a long history but the generic boundaries between it and environmental and conservation filmmaking are blurred. Nature, environment and animal imagery has been a mainstay of television, campaigning organisations and conservation bodies from Greenpeace to the Sierra Club, with vibrant images being used effectively on posters, leaflets and postcards, and in coffee table books, media releases, short films and viral emails to educate and inform the general public. However, critics suggest that wildlife film and photography frequently convey a false image of the state of the world’s flora and fauna. The environmental educator David Orr once remarked that all education is environmental education, and it is possible to see all image-based communication in the same way. The Media, Animal Conservation and Environmental Education has contributions from filmmakers, photographers, researchers and academics from across the globe. It explores the various ways in which film, television and video are, and can be, used by conservationists and educators to encourage both a greater awareness of environmental and conservation issues, and practical action designed to help endangered species. This book is based on a special issue of the journal Environmental Education Research.

Public participation by appeal - insights from empirical evaluation in Finland

Environmental law increasingly provides for participatory rights, including appeal rights, to ensure informed, legitimate decision-making. Despite consensus around the general need for participatory rights, including strong ones such as a right to appeal, public participation in environmental decision-making is often criticised. The critics' main argument is that the negative side effects resulting particularly from the use of strong participatory rights outweigh their benefits. Recent regulatory trends arising from better regulation policy to make environmental decision-making more cost-efficient tend to pay special attention to such arguments despite limited empirical evidence. This article provides evidence using material-concerning appeals against pollution permits in Finland and suggests that judicial review is a necessary and effective process for both protecting citizens' rights and improving the quality of environmental protection. © The Author [2008].

Variation in the length of an undergraduate degree:participation and outcomes

Recent policy in England has advocated the introduction of fast-track degrees to provide an alternative, shorter route to a bachelor's degree. It has been argued that this will widen participation in higher education and increase labour market flexibility by providing an option in which undergraduates spend one fewer years out of the labour market. Critics have suggested that the outcomes from this new undergraduate option will be worse than those for students following the standard length of undergraduate degree (which is three years for most subjects studied at universities in England). This criticism is based on a belief that students on the shorter degrees will be encouraged to 'cram', having less opportunity for reflection that will foster a deep understanding. These arguments are evaluated using data which compare students following two and three year degrees in the same subjects at the same university. © 2012 Copyright Society for Research into Higher Education.

The fevered novel from Balzac to Bernanos:frenetic Catholicism in crisis, delirium and revolution

Book Review: The Fevered Novel from Balzac to Bernanos: Frenetic Catholicism in Crisis, Delirium and Revolution. By Francesco Manzini. (IGRS Books). London: Institute of Germanic and Romance Studies, 2011. 264 pp. Full text: This monograph is an important and compelling account of a novelistic tradition that stretches from Georges Bernanos back to Balzac, by way of Léon Bloy, Joris-Karl Huysmans, and Barbey d'Aurevilly. Depending on a master plot that evokes Maistrean themes of blood, sacrifice, and redemption, working in a feverish female body, this canon combines Romantic freneticism and anti-Enlightenment religion to create a compound that Francesco Manzini calls ‘frenetic Catholicism’. The theme of fever, Manzini tells us, was commented on by Huysmans in writing about Barbey d'Aurevilly. When André Gide read Bernanos's Sous le soleil de Satan, he dismissed it as a rehash of Bloy and Barbey. In this present work Manzini aims to make us aware once more of the gradually intensifying themacity of fever in writings more usually classed in theologo-literary categories. His analysis encompasses (though is not restricted to) Balzac's Ursule Mirouët, Barbey d'Aurevilly's Un prêtre marié, Huysmans's En rade, Bloy's Le Désespéré and La Femme pauvre, and Bernanos's Nouvelle histoire de Mouchette. Thus, as Manzini argues in his conclusion, between the freneticism of the Romantics and that of the surrealists this corpus represents an intermediary wave of freneticism, foregrounding fever, hyperconsciousness, dreamlike episodes, and female automatism. Manzini's knowledge of, and ease amidst, the sources is constantly impressive. Much like Richard Griffiths before him (The Reactionary Revolution: The Catholic Revival in French Literature, 1870–1914 (London: Constable, 1966)), he has read both the bad novels and the good ones. For that we are in his debt. His commentary thrives on the oddities of his subjects. He points quite rightly to the peculiar hubris of writers whose contempt for the secular excesses of scientism leads them down a cul-de-sac of primitive medical quackery. Likewise, he underlines how Zola's attempt to unwrite Barbey — exorcising the former's anti-Romantic animus, as much as scratching his anticlerical itch — leads him to recapitulate Barbey's religious authoritarianism in the secular vernacular of patriarchy. Les espèces qui se rapprochent se mangent, to paraphrase Bernanos (Les Grands Cimetières sous la lune). In spite of all Manzini's tightly organized analysis, however, this reader wonders whether the fevered novel ‘best allowed contemporaries — and now […] literary critics and historians — to imagine the issues at stake in the amorphous scientistic, religious, and political debates’ of the period (p. 17). Below the ideological clashes of nineteenth-century science and religion, the two contending dynamics of anthropocentrism and theocentrism are attested and, it can be argued, even more perfectly dramatized in other Catholic literature (Charles Péguy's poetry, for example). In these terms, what distinguishes the Catholic frenetics from their Romantic or surrealist counterparts is that their fevered subject represents an attempt to build a road out of what Canadian philosopher Charles Taylor calls ‘buffered’ individuality, and back towards the theocentric porous subject who is open to divine influence. By way of minor corrections, nuns do not take holy orders (p. 94) but make religious profession by taking vows. Also, the last Eucharistic host is not extreme unction (p. 119) but viaticum.

Partnership and organizing:an empirical assessment of two contrasting approaches to union revitalization in the UK

The Trades Union Congress (TUC) in Britain has been advocating two contrasting approaches to union revitalization namely: ‘labour—management partnership’ and ‘union organizing’. Using a case study of a public services union this article examines empirically the prospects of union revival offered by these two contrasting approaches. Public services with relatively high union density should offer better prospects for union revival through partnership. However, the authors’ findings indicate that even in public services, partnership was not associated with management’s support for union recruitment, better facility time provisions for union representatives, lower worker grievances or union membership gains. Rank-and-file organizing, on the other hand, was associated with lower worker grievances, greater worker satisfaction with the union, higher worker involvement in union activities and union membership gains. Overall, the findings question the ‘mutual gains’ assertions of partnership advocates and lend support to the critics of partnership who propose an alternative organizing approach to union revitalization.
