Using sub-word-level information for confidence estimation with conditional random field models

The task of word-level confidence estimation (CE) for automatic speech recognition (ASR) systems stands to benefit from the combination of suitably defined input features from multiple information sources. However, the information sources of interest may not necessarily operate at the same level of granularity as the underlying ASR system. The research described here builds on previous work on confidence estimation for ASR systems using features extracted from word-level recognition lattices, by incorporating information at the sub-word level. Furthermore, the use of Conditional Random Fields (CRFs) with hidden states is investigated as a technique to combine information for word-level CE. Performance improvements are shown using the sub-word-level information in linear-chain CRFs with appropriately engineered feature functions, as well as when applying the hidden-state CRF model at the word level.

Genteel revolutionaries: the lives of Anna and Thomas Haslam

The lives of Thomas and Anna Haslam were dedicated to the attainment of women's equality. They were feminists before the word was coined. In an era when respectable women were not supposed to know of the existence of prostitutes, Anna became empowered to do the unthinkable, not only to speak in public but to discuss openly matters sexual and to attack the double standard of sexuality which was enshrined in the official treatment of prostitutes. Their life-long commitment to the cause of women's suffrage never faltered, despite the repeated discouragement of the fate of bills defeated in the House of Commons. The Haslams represented an Ireland which did not survive them. While they were dedicated to the union with Westminster, they worked happily with those who applied themselves to its destruction. Although in many ways they exemplified the virtues of their Quaker backgrounds, they did not subscribe to any organised religion. Despite living in straitened circumstances, they were part of an urban intellectual elite and participated in the social and cultural life of Dublin for over fifty years. It is tempting to speculate how the Haslams would have fared in post independence Ireland. Hanna Sheehy Skeffington who had impeccable nationalist credentials, was effectively marginalised. It is likely that they would have protested against discriminatory legislation in their usual law abiding manner but, in a country which quickly developed an overwhelmingly Roman Catholic ethos, would they have had a voice or a constituency? Ironically, Thomas's teaching on chastity would have found favour with the hierarchy; his message was disseminated in a simple and more pious manner in numerous Catholic Truth Society pamphlets. The Protestant minority never sought to subvert the institutions of the state, was careful not to criticise and kept its collective head down. Dáil Éireann was not bombarded with petitions for the restoration of divorce facilities or the unbanning of birth control. Those who sought such amenities obtained them quietly 'in another jurisdiction.' Fifty years were to pass before the condom wielding 'comely maidens' erupted on to the front pages of the Sunday papers. They were, one imagines, the spiritual descendants of the militant rather than the constitutional suffrage movement. "Once and for all we need to commit ourselves to the concept that women's rights are not factional or sectional privileges, bestowed on the few at the whim of the many. They are human rights. In a society in which the rights and potential of women are constrained no man can be truly free." These words spoken by Mary Robinson as President of Ireland are an echo of the principles to which the Haslams dedicated their lives and are, perhaps, a tribute to their efforts.

The Cliché as Critique and Complaint

The cliché is a peripheral term in our critical vocabulary. Reviewers, critics, and editors speak of clichés, but dictionaries of critical terms rarely provide entries on the word. This paper asks whether pointing out clichés represents a form of critique or whether it is just quibbling, and how we draw the line between scrutiny and pedantry.

Mathematical notation in formal specification: Too difficult for the masses? [Correspondence]

The phrase “not much mathematics required” can imply a variety of skill levels. When this phrase is applied to computer scientists, software engineers, and clients in the area of formal specification, the word “much” can be widely misinterpreted with disastrous consequences. A small experiment in reading specifications revealed that students already trained in discrete mathematics and the specification notation performed very poorly; much worse than could reasonably be expected if formal methods proponents are to be believed.

Reconsidering Respect: Its Role in the British Prison Service

This article examines the meaning of respect in the interpersonal relationships within Her Majesty’s Prison Service. It is argued that respect-as-esteem and respect-asconsideration are often confused and unequally emphasised in modern society. This confusion is especially evident within the prison context where, due to the prison service’s ‘decency agenda’, the respectful treatment of inmates has become a topical issue. What does respect mean in prison? Why is it important? How can respectful relationships be established between staff and inmates? This article discusses these questions and proposes that there are different forms of respect possible between people. It is argued that there needs to be a recognition of the nuances of meaning when we use the word respect and that ‘respect-as-consideration’ may be the form of respect most consistently achievable, at the present time, within interpersonal relationships in English and Welsh prisons.

Judicial Rehabilitation and the ‘Clean Bill of Health’ in Criminal Justice.

Drawing on an important survey of European and Australian policies toward ‘judicial rehabilitation,’ this article makes the following arguments. First, the rehabilitation movement should return to the origins of the word ‘rehabilitation’ and focus at least as much on efforts to remove and relieve ex-prisoner stigma as on treatment and reform efforts. There will be no ‘rehabilitation revolution’ without this. Second, these efforts should involve active, not passive redemption. Rehabilitation processes that require almost a decade or more of ‘crime-free’ behaviour before forgiving an individual for his or her crimes are just and fair, but they miss the point of rehabilitation. Policies should encourage, support and facilitate good behaviour and not just reward it in retrospect. Third, rehabilitation should not just be done, but be ‘seen to be done,’ ideally in a ritualised format. This sends an important message to the individual and wider society. Finally, I argue that it may be better to forgive than forget past crimes. That is, rather than burying past crimes as if they never happened, states should instead acknowledge and formally recognise that people can change, that good people can do bad things, and that all individuals should be able to move on from past convictions.

Beyond the Sign. Henri Meschonnic's Poetics of Rhythm and Continuum. Towards an Anthropological Theory of Language

Basing the conception of language on the sign represents also an obstacle to the awareness of certain elements of human life, especially to a full understanding of what language or art do, Henri Meschonnic’s poetics of the continuum and of rhythm criticizes the sign based on Benveniste’s terms of rhythm and discourse, developing an anthropology of language. Rhythm, for Meschonnic, is no formal metrical but a semantic principle, each time unique and unforeseeable. As for Humboldt, his starting point is not the word but the ensemble of speech; language is not ergon but energeia. The poem then is not a literary form but a process of transformation that Meschonnic defines as the invention of a form of life by a form of language and vice versa. Thus a poem is a way of thinking and rhythm is form in movement. The particular subject of art and literature is consequently not the author but a process of subjectivation – this is the contrary of the conception of the sign. By demonstrating the limits of the sign, Meschonnic’s poetics attempts to thematize the intelligibility of presence. Art and literature raise our awareness of this element of human life we cannot grasp conceptually. This poetical thinking is a necessary counterforce against all institutionalization.

In the Shadows of the Old Town: Thomas Anna and 19th-century Glasgow

In 1858, a volume entitled Midnight Scenes and Social Photographs – being sketches of life in the streets, wynds and dens of the city of Glasgow was published under the pseudonym of ‘Shadow’ by Alexander Brown, a Glaswegian flâneur and reformer. Its frontispiece is an etching which depicts a theatre-like proscenium arch whose curtains have been withdrawn to reveal to the audience all the poverty, destitution and disorder that one was likely to find after dark in the insalubrious quarters of the city. At the extreme left-hand side, partly obscured by the curtain a silhouetted figure stands behind an unwieldy camera perched on a tripod. Distinctly unaffected by the mêlée, an arm is calmly raised and a finger precisely arched in the moment before the shutter is clicked and the scene committed to record. The volume, however, relies exclusively on textual descriptions to evoke the underside of the city and contains no photographs at all. Instead, the use of the word photograph in the title can be understood as a metaphor for detached scientific objectivity, a quality much celebrated by nineteenth-century reformers and investigators of social ills. As it happened, a decade after Shadow disappeared into the labyrinthine back-lands of Old Town Glasgow, he was followed there by a real photographer. In 1868, Thomas Annan was commissioned by the City Improvements Trust to take photographs of the Old Town in its last moments of existence before it was pulled down under a series of legislative acts. But perhaps paradoxically, given Shadow’s faith in the analytical properties of photography, Annan’s work seems to refute much of the material contained in Midnight Scenes and other similar tracts. Instead of the dens, shebeens, labyrinths and rowdy crowds described by Shadow, Annan’s depictions of the Old Town convey a static, calm environment, one which is often sparsely inhabited by a curious but apparently orderly population.

Taking account of the sensational tendencies of many reformists’ texts, this paper investigates the discrepancies between the two representations, focussing in particular on the constraints which operated on Annan during his commission. It argues that Annan’s compositions – which became very influential on other 19th century photographers of everyday life such as John Thomson or Jacob Riis – far from being dispassionate analytical works, emerged as a result of a matrix of factors which included: photographic and artistic precedents; Annan’s own predilections as a photographer; technological limitations; the nature of the commission from the City Improvements Trust and political climate in which it was given; the medieval urban fabric in which he had to operate; and, perhaps, most importantly, the identity of the Old Towns inhabitants themselves.

Designing Bare Essentials: Aldi, Lidle and the architectures of cheapness

They’re cheap. They’re in every settlement of significance in Britain, Ireland and elsewhere. We all use them but perhaps do not always admit to it. Especially, if we are architects.
Over the past decades Aldi/Lidl low cost supermarkets have escaped from middle Europe to take over large tracts of the English speaking world remaking them according to a formula of mass-produced sheds, buff-coloured cobble-lock car parks, logos in primary colours, bare-shelves and eclectic special offers. Response within architectural discourse to this phenomenon has been largely one of indifference and such places remain, perhaps reiterating Pevsner’s controversial insights into the bicycle shed, on the peripheries of what we might term architecture. This paper seeks to explore the spatial complexities of the discount supermarket and in doing so open up a discussion on the architecture of cheapness. As a road-map, it takes former managing director Dieter Brandes’ treatise on the Aldi formula, Bare Essentials: the Aldi Way to Retailing, and investigates the strategies through which economic exigencies manifest themselves in a series of spatial tactics which involve building. Central to this is the idea of architecture as system rather than form and, in Aldi/Lidl’s case, the result of a spatial network of flows. To understand the architecture of the supermarket, then, it is necessary to measure the times and spaces of supply across the scales of intersection between global and local.
Evaluating the energy, economy and precision of such systems challenges the liminal position of the commercial, the placeless and especially the cheap within architectural discourse. As is well known, architectures of mass-production and prefabrication and their origins exercised modernist thinkers such as Sigfried Giedion and Walter Gropius in the early twentieth century and has undergone a resurgence in recent times. Meanwhile, the mapping of the hitherto overlooked forms and iconography of commerce in Learning from Las Vegas (1971) was extended by Rem Koolhaas et al into an investigation of the technologies, systems and precedents of retail in the Harvard Design School Guide to Shopping, thirty years later in 2001. While obviously always a criteria for building, to find writings on architecture which explicitly celebrate cheapness as a design virtue or, indeed, even iterate the word cheap is more difficult. Walter Gropius’ essay ‘How can we build cheaper, better, more attractive houses?’ (1927), however, situates the cheap within the discussions – articulated, amongst others, by Karl Teige and Bruno Taut – surrounding the minimal dwelling and the moral benefits of absence of the 1920s and 30s.
In our contemporary age of heightened consumption, it is perhaps fitting that an architecture of bare essentials is defined in retail rather than in housing, a commercial existenzminimum where the Miesian paradox of ‘less is more’ is resold as a paradigm of ‘more for less’ in the ubiquitous yet overlooked architectures of the discount supermarket.

Search filters: mapping the literature using a novel form of content analysis.

Background: Search filters are combinations of words and phrases designed to retrieve an optimal set of records on a particular topic (subject filters) or study design (methodological filters). Information specialists are increasingly turning to reusable filters to focus their searches. However, the extent of the academic literature on search filters is unknown. We provide a broad overview to the academic literature on search filters.
Objectives: To map the academic literature on search filters from 2004 to 2015 using a novel form of content analysis.
Methods: We conducted a comprehensive search for literature between 2004 and 2015 across eight databases using a subjectively derived search strategy. We identified key words from titles, grouped them into categories, and examined their frequency and co-occurrences.
Results: The majority of records were housed in Embase (n = 178) and MEDLINE (n = 154). Over the last decade, both databases appeared to exhibit a bimodal distribution with the number of publications on search filters rising until 2006, before dipping in 2007, and steadily increasing until 2012. Few articles appeared in social science databases over the same time frame (e.g. Social Services Abstracts, n = 3).
Unsurprisingly, the term ‘search’ appeared in most titles, and quite often, was used as a noun adjunct for the word 'filter' and ‘strategy’. Across the papers, the purpose of searches as a means of 'identifying' information and gathering ‘evidence’ from 'databases' emerged quite strongly. Other terms relating to the methodological assessment of search filters, such as precision and validation, also appeared albeit less frequently.
Conclusions: Our findings show surprising commonality across the papers with regard to the literature on search filters. Much of the literature seems to be focused on developing search filters to identify and retrieve information, as opposed to testing or validating such filters. Furthermore, the literature is mostly housed in health-related databases, namely MEDLINE, CINAHL, and Embase, implying that it is medically driven. Relatively few papers focus on the use of search filters in the social sciences.

O exercício profissional e a educação contábil : o caso do Conselho Federal de Contabilidade do Brasil

Esta tese analisa a preocupação do Conselho Federal de Contabilidade (CFC) com a formação do profissional e com a educação contábil ao longo da sua história, mas também explora o seu panorama atual, principalmente no que se refere à utilização do exame de suficiência como ferramenta de fiscalização preventiva dos profissionais e os fatores explicativos da taxa de aprovação. Para responder a este objetivo geral, a tese desenvolve-se em dois estudos complementares. No primeiro, estuda a criação do CFC e o processo de regulamentação da profissão, usando uma perspectiva interpretativa, fundamentada na sociologia das profissões, com base em dados documentais e gravações recolhidas no arquivo do Conselho. Daí conclui-se que o Sistema CFC/CRCs foi criado em consequência do forte desejo dos profissionais atuantes na área, do surgimento simultâneo do bacharelado em Ciências Contábeis no Brasil e da intervenção do governo corporativista de Getúlio Vargas num contexto de desenvolvimento econômico. O projeto profissional que surgiu nesta ocasião viria “acomodar” todos os rivais, o que fez com que o nível de homogeneização dos membros fosse mínimo, já que incluía aqueles que só tinham experiência prática e uma grande percentagem com diploma do ensino médio. A evidência empírica recolhida permite concluir que a manutenção desta categoria, por um tão longo período, acabou por desprestigiar a profissão. Apenas recentemente, no contexto da adoção das Normas Internacionais de Contabilidade (IFRS, na sigla em inglês), a profissão haveria de obter o credenciamento ao nível universitário. A esta altura, o CFC ganhou não só o direito ao credenciamento a nível universitário, como também o de selecionar os melhores candidatos através de um exame. Apesar dessa evolução positiva, a preocupação deste organismo profissional com a formação dos seus membros continua a ser grande, em função do baixo progresso da “base cognitiva” da profissão, observando-se um número reduzido de mestres e doutores em Contabilidade no Brasil, embora tenha havido, nos últimos anos, uma proliferação de Instituições de Educação Superior (IES) e de cursos de Ciências Contábeis que não foi acompanhada de uma evolução qualitativa.Na segunda parte da tese, desenvolve-se um estudo quantitativo de índole positivista, para tentar explicar as razões dos maus resultados no Exame do CFC. Usando dados recolhidos no Conselho Federal de Contabilidade, os resultados da pesquisa revelam que a taxa de aprovação nas edições do Exame de Suficiência não difere, significativamente, entre as regiões e estados do Brasil, sendo cada vez mais baixo ao longo dos anos. Apesar de uma análise de correlações demonstrar que a formação ao nível da pós-graduação dos docentes estar correlacionada positivamente com a taxa de aprovação no Exame do CFC, numa análise abrangente essas variáveis perderam força, devido, talvez, ao fato de estarem incorporadas em outras variáveis que se mostraram significativas, como o Índice Geral de Cursos e o Conceito de Curso. Além dessas variáveis que se revelaram positivamente relacionadas com a taxa de aprovação, também os resultados do exame Enade, o gênero e a idade se mostraram significativos. O baixo resultado do Enade é particularmente importante, já que reforça as preocupações do CFC sobre a proliferação de IES e de cursos, e o baixo desempenho que algumas IES apresentam, nomeadamente, por possuírem um nível reduzido de mestres e de doutores e, por outro lado, um número elevado de professores “horistas” e um investimento em pesquisa muito baixo.

Can the Revised UK Code Direct Practice?

The Nursing and Midwifery Council, the United Kingdom regulator of nursing and midwifery has recently revised its professional code of practice. This paper begins by arguing that a professional code must be capable of sustaining close reading and of action guidance. Using four exemplar clauses it is argued that the new revised code does not met this purpose. First, I show that in setting out requirements for consent and documentation, the meaning of the relevant clause has changed significantly during the editing process so that a literal reading of the final document bears little relation to established professional practice. Second, I argue that the clause concerning the nature of professional relationships has also been altered during the editing process so that it is inconsistent with other professional groups and established accounts of the professional nurse-patient relationship. Third, I argue that the clause concerning disclosure of confidential information, which survived revision and editing with its meaning intact is nevertheless factually incorrect and inconsistent with UK law and authoritative guidance. Finally, fourth, I argue that use of the word ‘inappropriate’ is inappropriate as it amounts to meaningless circularity, discussed in relation to a clause on expressing personal beliefs. Taken together, these examples demonstrate that the Code is seriously flawed and does not fulfil its purpose. One way that simple prescriptive clauses in the Code can be usefully understood is through the provision of detailed guidance. I argue that the NMC has changed its position on its view of the value of guidance and has significantly reduced the amount of written guidance and advice is provides. The paper concludes by arguing that in order to meet its action directing function, further clarifying revision and the provision of detailed guidance is required.

Heidegger on the way of thinking

This thesis attempts to clarify what Heidegger meant by the term "thinking" (Denken), where this ^'meanr is submitted in the double sense: firstly, in the sense of what Heidegger intended by the use and exposition of this term that we find in his lecture series. Was Heisst Denken?, where Heidegger quickly makes it clear that this intention is to actually bring thinking on the way, viz. making provision for the leap into thinking, and where this intention was carried out with the employment of a specific guiding phrase. In the second sense, it is an attempt at clarifying the meaning of the term. But this is not to say that we are here simply out to see how Heidegger defines the word '*thinking." It is in fact precisely within such definitive discourse that thought dies out. It is not merely be a case of defining a word, because this enterprise would be just as shallow as much as it would be unworkable. It is for this reason that Heidegger decided to establish for himself the task, not merely of explaining thinking as something to be beheld at a distance, but rather of bringing thinking underway by means of his lecture, proclaiming that, "Only the leap into the river tells us what is swimming. The question 'What is called thinking?' can never be answered by proposing a definition of the concept thinking, and then diligently explaining what is contained in that definition." (WCT, 21) This being Heidegger's intention, in order to understand Heidegger in his treatment of the term thinking, it is clear that we must also undergo an experience with thinking. It is in this spirit that the present work was written so as to collaborate the two senses of what Heidegger meant by "thinking."
