Human figure segmentation using independent component analysis

In this paper, we present a Statistical Shape Model for Human Figure Segmentation in gait sequences. Point Distribution Models (PDM) generally use Principal Component analysis (PCA) to describe the main directions of variation in the training set. However, PCA assumes a number of restrictions on the data that do not always hold. In this work, we explore the potential of Independent Component Analysis (ICA) as an alternative shape decomposition to the PDM-based Human Figure Segmentation. The shape model obtained enables accurate estimation of human figures despite segmentation errors in the input silhouettes and has really good convergence qualities.

Parent Issues: How Life on Mars Negotiates a Television Generation Gap

In defining what he termed 'Television's Second Golden Age', Robert J.Thompson refers to characteristics such as being 'not regular TV', internal continuity, mixed genres but an aspiration towards 'realism', complex writing, self-consciousness and intertextuality. Such characteristics are displayed by the BBC series Life on Mars (2006-2007) which intermingles the Seventies tough cop show with psychological fantasy. This chapter examines the way that the series can be understood as a dramatisation of the negotiation that the creators undertook with their Seventies source material to update it for the values and qualities of contemporary television drama. It will emphasise the importance of television in the generation of the imagined 1973 and its characters, but also as an ongoing connection between the real and the imagined within the programme, including forming a breach of the boundaries between the two. Sam's actions within his Seventies world to remake it to include his own ideas of justice and due process while retaining the passion and freedom of action that the milieu provides will also be be examined in relation to the series' creators' needs to remake the Seventies tough-cop show in the light of modern social and media mores. The paper will also consider how Sam has to come to terms with his father's crimes, as the series' creators had to come to terms with the 'crimes' of taste, morality and approach of their 'parent' programmes from the Seventies' Golden Age.

Narrative on the Net:Bill and his hyper- lives, loves and texts

Narrative, by its very nature, is changing as a consequence of internet developments. Hypertexts are, for example, changing not just the way in which we disseminate information, but also the ways in which we write, speak and think. In this paper a narrative approach is taken to assess a case study of a person’s extensive home site on the web. Bill maintains an extensive web site documenting his life with Parkinson’s Disease, his love for running and all matters relating to the island of Montserrat in the Eastern Caribbean. Bill’s Parkinson’s Disease hypertext diary forms the focus of this case study of a life spent on-line. Though set up just as a diary about this progressively degenerative disease, because of its hypertextual qualities, this paper argues that it is through the diary that Bill comes to produce and sustain - to narrate - his identity. This paper thus contributes to the position that though hypertext encourages the construction of fragmented and false identity narratives, it is also a medium for sustaining linear and coherent representations of self-identity.

Additional Accommodation Church of St George and St Thomas

A vibrant inner city parish needed space for meetings, language classes, children’s play and other support accommodation as well as a clearer link between the interior of the listed church and the space outside.

The project builds itself about the entrance to the church. The form is manipulated such that the intervention recedes from those entering the church, drawing them into the plan before becoming readable as an addition. The resultant poché between this entrance sequence and the fabric of the church is hollowed out to provide the required accommodation. These rooms are insulated and lined in cork to allow for their use separate to the main body of the church. With budget at a premium the construction methodology was developed from an analysis of traditional Irish boat building techniques, which allowed the use of the solid timber to act as the primary structure with no additional material support.

Constructed in solid walnut the intervention reads with the existing brick interior and yet is clearly identifiable as a contemporary addition.

Aims / Objectives Questions

1 To accommodate new space inside an existing protected structure.
2 To form a new threshold between interior and exterior.
3 To develop an affordable means of construction that would be durable and rapid to erect.
4 To make a contemporary addition in sympathy with the qualities of the existing protect structure, in line with best conservation practice and research.
5 Traditional forms of construction as a model for contemporary technologies.

A study of the relational aspects of the culture of academic medicine

PURPOSE: The impact of medical school culture on medical students has been well studied, but little documentation exists regarding how medical faculty experience the culture in which they work. In an ongoing project, the National Initiative on Gender, Culture and Leadership in Medicine, the authors are investigating how the existing culture of academic medical institutions supports all faculty members' ability to function at their highest potential. METHOD: The authors conducted a qualitative study of faculty in five disparate U.S. medical schools. Faculty in different career stages and diverse specialties were interviewed regarding their perceptions and experiences in academic medicine. Analysis was inductive and data driven. RESULTS: Relational aspects of the culture emerged as a central theme for both genders across all career categories. Positive relationships were most evident with patients and learners. Negative relational attributes among faculty and leadership included disconnection, competitive individualism, undervaluing of humanistic qualities, deprecation, disrespect, and the erosion of trust. CONCLUSIONS: The data suggest that serious problems exist in the relational culture and that such problems may affect medical faculty vitality, professionalism, and general productivity and are linked to retention. Efforts to create and support trusting relationships in medical schools might enhance all faculty members' efforts to optimally contribute to the clinical, education, and research missions of academic medicine. Future work will document the outcomes of a five-school collaboration to facilitate change in the culture to support the productivity of all medical faculty. © 2009 Association of American Medical Colleges.

Spin-Based Diagnostic of Nanostructure in Copper Phthalocyanine-C-60 Solar Cell Blends

Nanostructure and molecular orientation play a crucial role in determining the functionality of organic thin films. In practical devices, such as organic solar cells consisting of donor-acceptor mixtures, crystallinity is poor and these qualities cannot be readily determined by conventional diffraction techniques, while common microscopy only reveals surface morphology. Using a simple nondestructive technique, namely, continuous-wave electron paramagnetic resonance spectroscopy, which exploits the well-understood angular dependence of the g-factor and hyperfine tensors, we show that in the solar cell blend of C-60 and copper phthalocyanine (CuPc)-for which X-ray diffraction gives no information-the CuPc, and by implication the C-60, molecules form nanoclusters, with the planes of the CuPc molecules oriented perpendicular to the film surface. This information demonstrates that the current nanostructure in CuPc:C-60 solar cells is far from optimal and suggests that their efficiency could be considerably increased by alternative film growth algorithms.

Pain expression in neonates:facial action and cry

Pain expression in neonates instigated by heel-lance for blood sampling purposes was systematically described using measures of facial expression and cry and compared across sleep/waking states and sex. From gate-control theory it was hypothesized that pain behavior would vary with the ongoing functional state of the infant, rather than solely reflecting tissue insult. Awake-alert but inactive infants responded with the most facial activity, consistent with current views that infants in this state are most receptive to environmental stimulation. Infants in quiet sleep showed the least facial reaction and the longest latency to cry. Fundamental frequency of cry was not related to sleep/waking state. This suggested that findings from the cry literature on qualities of pain cry as a reflection of nervous system 'stress', in unwell newborns, do not generalize directly to healthy infants as a function of state. Sex differences were apparent in speed of response, with boys showing shorter time to cry and to display facial action following heel-lance. The findings of facial action variation across sleep/waking state were interpreted as indicating that the biological and behavioral context of pain events affects behavioral expression, even at the earliest time developmentally, before the opportunity for learned response patterns occurs. Issues raised by the study include the importance of using measurement techniques which are independent of preconceived categories of affective response.

Life-Cycle Energy Analysis of a Modular/Off-Site Building School

This paper is concerned with assessing the building’s the energy efficiency and qualities of a modular design for the education industry, in order assess the long economic benefits. The research includes a life-cycle energy and cost analysis of the school building design, predicting the impact on the operational cost of the building as a result of the addition of photovoltaic panels. The paper also includes a comparative study between the ECO Modular Solutions building, and a current standard prefabricated school building, quantifying the savings in CO2 emissions and savings in cost.

Cast Offs (Touchstones in Practice)

The working process of an architect is not often shown publicly, as the finished buildings, more particularly images and publications on them tend to dominate how architecture is communicated. In this there is something lost. The experience of the building, which is its most valuable aspect, is only possible by being there physically. Photography and other means of representation of architecture can tend to an overly perfected and artificial read of both the building and how the design was produced. In truth the design process for a building is a complex one, full of chance discoveries, multiple abandoned ideas, and refinement which is lateral as well as rational.

When we were asked to exhibit it struck us that we should address this deficit in some small way. These are models made as part of the design process for four projects (an arts centre, a womens refuge, a villa and four artists studios). An important part of our work method is to try to explore the material qualities of the buildings we are working on. To advance this we commonly make models to allow us to make discoveries and to advance the project so that the finished building is imbued with material and spatial character. These models are not made to show the final design of the building but to highlight an aspect that we are interested in exploring, in some cases this is about a space, in others about texture and its relationship to form. We chose these four models as all in some way allowed us to make discoveries about the project being explored. This discovery, once made, is what we value. The model itself serves only to produce this, and once made we can cast off the model and move on. We show them, not as architecture, but as touchstones for ideas out of which architecture may come.

Sounds of the City

“Sounds of the City” is a large-scale community project and exhibition commissioned by the Metropolitan Arts Centre (MAC) and led by artists from the Sonic Arts Research Centre (SARC), Queen’s University Belfast. Over a four-month period, the artists worked together with two intergenerational groups in Belfast with the aim of addressing specific sound qualities of places, events and stories. Themes that surfaced from this process constitute the basis for the exhibition which promotes listening as a form of intersecting daily life, identity and memory. Five installations address aural contexts ranging from Belfast’s industrial heritage to the local family home. These are shaped by present and past experiences of workshop participants at Dee Street Community Centre in East Belfast and Tar Isteach in North Belfast. The themes and contents of these installations center upon the relationship between sound and memory, sound and place, and the documentation of everyday personal auditory experience.
All materials exhibited have emerged through workshops, interviews and field-recording sessions. Workshops acted as a basis from which to inform each group about the project’s aims, methods of listening, methods of documenting sound and the wider areas of soundscape studies and acoustic ecology. They also provided a central point allowing participants to organize outside activities and share material for exhibition.
“Sounds of the City” explores the relationship between sound and community through everyday life and presents a dynamic and ever-changing soundscape that shapes Belfast’s identity.

Sounds of the City has been exhibited at the MAC, Belfast 2012 and at Espaço Ecco, Brasilia 2013.

An analysis of the masking of speech by competing speech using self-report data (L)

Many of the items in the “Speech, Spatial, and Qualities of Hearing” scale questionnaire [S. Gatehouse and W. Noble, Int. J. Audiol.43, 85–99 (2004)] are concerned with speech understanding in a variety of backgrounds, both speech and nonspeech. To study if this self-report data reflected informational masking, previously collected data on 414 people were analyzed. The lowest scores (greatest difficulties) were found for the two items in which there were two speech targets, with successively higher scores for competing speech (six items), energetic masking (one item), and no masking (three items). The results suggest significant masking by competing speech in everyday listening situations.

Environmental Aspects of Underground Construction and Exploration of Underground Structure – State of the Art

An underground work (such as a tunnel or a cavern) has many, well known, environmental qualities such as: no physical barriers crossing the land, less maintenance costs than an analogous surface structure, less expenses for heating and conditioning; a localized emission of noise, gas, dust during operation and, finally, a better protection against seismic actions.
It cannot be forgotten, anyway, that some negative environmental features are present such as, for example, : perturbation, pollution and drainage of the groundwater; settlements; disposal of waste rock.
In the paper the above mentioned concepts are discussed and analysed to give a global overview of all this aspects.

K-Contagion: Sound, Space and Speed in Psy's 'Gangnam Style'

Park Jae-Sang’s (otherwise known as PSY) bewilderingly successful pop contagion ‘Gangnam Style’ needs no introduction. As of January 2013, it has become the most watched video in YouTube’s history and has garnered over 1.23 billion hits since. ‘Gangnam Style’ has also become a rapid global pop phenomenon with multiple parodic reproductions, imitations and adaptations; Rapper PSY himself has become an international name and styled as the ‘anti-hero’ of the glamour-driven K-pop scene. His fame has transcended the social sphere and permeated the political stratosphere with politicians such as Barrack Obama and David Cameron being among the many whom PSY has exchanged pleasantries with. Apart from breaking ground and creating social and media history in many ways, ‘Gangnam Style’ has even been purported by UN Secretary-General Ban Ki Moon to be a “force for world peace” – cultural barriers are demolished as the world dances. Underlying this sentiment is the video’s almost universal appeal that assumes a supracultural yet equally paradoxical translatability: Korea’s neoteric ‘K-Wave’ phenomenon is at once local yet global, and where the latter is predicated on the former quality. The paper’s concern is thus two-fold. It will consider the dromological aspects of this musical contagion as it exemplifies and performs quite literally Paul Virilio’s thesis that the modern condition is driven by speed yet arrested to a dictatorship of movement. While many theories have been put forward for this astounding pop peculiarity, this paper would also examine the intercultural currents that advocate such a global (pop) cultural response. Through an analysis of sonic qualities – digital techno-beat rhythms, synth-based musicality, cyclical lyrics, horse-galloping movements – and acoustic receptions, it will consider the simultaneous and dichotomous currents of glocalisation and globalisation as it relates to the ways in which sonic ‘hyper-links’ establish new concepts of global-cultural identities even as these seem to be interrogated in the borderless worlds of hyper-mediatised realities and cultural technologies.

Fleuve glauque : les départements de la Seine, banlieue des romans « Spécial Police » de Frédéric Dard

This paper studies the representation of suburbs as a place of anguish in the “Special Police” novels (Fleuve Noir publisher, Paris) by Frédéric Dard. This anxiety, it is argued, is what lends this collection of 25 novels some of their essential qualities, their unhealthy climate and absolute darkness. Dard’s suburbs fit into the traditions of realism; but the atmosphere, characters and plots owe to the American hardboiled school and like in film noir, space is stylized and dramatized, and often used to express a judgment of moral nature. Spatial representations in these novels are part of a critique of civilization and constitute a comment on the social modernization and public intervention in the development of the French territory in the postwar period. The novels written by Frédéric Dard from the mid-1950s to mid-1960s offer a profoundly original representation of suburban angst and what was not yet known at the time as the suburban malaise. Avoiding clichés and excessively connoted referential spaces, Dard anchor these noir novels he called “novels of the night” in landscapes that are both biographical and intertextual. The West Suburbs of Paris and what was
to become the Yvelines department are at the centre of Dard’s novelistic geography, turning into a mythical and deadly space in which is negotiated an acculturation in France of the evil and ruined world described in American noir.

Mundane Mobilities in ‘Post-Socialist’ Sofia: Making Urban Borders Visible

This article reflects on an on-going research project which aims to expand the understanding of the production and transformation of urban borders in the Eastern European cities of the ex ‘communist bloc’, starting from the case of Sofia. It explores the proposition that there has been a prolific process of wall making in this city associated with ‘vanishing public spaces’, ‘rescaling of enclosure’, and ‘corrosion of the collective urban realm’ (Hirt, 2012). The paper seeks to understand the social and political effects of this process by delving into the sensorial, emotional and embodied experiences associated with the mundane mobilities of urban residents. Using participants’ self-directed photography and videos from ‘walk-along’ interviews it explores the ways in which borders are made visible and are produced, challenged or resisted through mobility, and delves into the associated senses of deepening social and spatial differentiation in the city.
