Real-life Social Attention in Children with Autism Spectrum Disorders

Autism is a neuro-developmental disorder defined by atypical social behaviour, of which atypical social attention behaviours are among the earliest clinical markers (Volkmar et al., 1997). Eye tracking studies using still images and movie clips have provided a method for the precise quantification of atypical social attention in ASD. This is generally characterised by diminished viewing of the most socially pertinent regions (eyes), and increased viewing of less socially informative regions (body, background, objects) (Klin et al., 2002; Riby & Hancock, 2008, 2009). Ecological validity within eye tracking studies has become an increasingly important issue. As of yet, however, little is known about the precise nature of the atypicalities of social attention in ASD in real-life. Objectives: To capture and quantify gaze patterns for children with an ASD within a real life setting, compared to two Typically Developing (TD) comparison groups. Methods: Nine children with an ASD were compared to two age matched TD groups – a verbal (N=9) and a non-verbal (N=9) comparison group. A real-life scenario was created involving an experimenter posing as a magician, and consisted of 3 segments: a conversation segment; a magic trick segment; and a puppet segment. The first segment explored children’s attentional preferences during a real-life conversation; the magic trick segment explored children’s use of the eyes as a communicative cue, and the puppet segment explored attention capture. Finally, part of the puppet section explored children’s use of facial information in response to an unexpected event. Results: The most striking difference between the groups was the diminished viewing of the eyes by the ASD group in comparison to both control groups. This was found particularly during the conversation segment, but also during the magic trick segment, and during the puppet segment. When in conversation, participants with ASD were found to spend a greater proportion time looking off-screen, in comparison to TD participants. There was also a tendency for the ASD group to spend a greater proportion of time looking to the mouth of the experimenter. During the magic trick segment, despite the fact that the eyes were not predictive of a correct location, both TD comparison groups continued to use the eyes as a communicative cue, whereas the ASD group did not. In the puppet segment, all three groups spent a similar amount of time looking between the puppet and regions of the experimenter’s face. However, in response to an unexpected event, the ASD group were significantly slower to fixate back on the experimenter’s face. Conclusions: The results demonstrate the reduced salience of socially pertinent information for children with ASD in real life, and they provide support for the findings from previous eye tracking studies involving scene viewing. However, the results also highlight a pattern looking off-screen for both the TD and ASD groups. This eye movement behaviour is likely to be associated specifically with real-life interaction, as it has functional relevance (Doherty-Sneddon et al., 2002). However, the fact that it is significantly increased in the ASD group has implications for their understanding of real life social interactions.

Invaders, Launchpads and Hybrids: The Importance of Transmediality in British Science Fiction Film in the 1950s

With its origins in the trick films of the 1890s and early 1900s, British science fiction film has a long history. While Things to Come (1936) is often identified as significant for being written by H.G.Wells, one of the fathers of science fiction as a genre, the importance of the interactions between media in the development of British science fiction film are often set aside. This chapter examines the importance of broadcast media to film-making in Britain, focusing on the 1950s as a period often valourised in writings about American science fiction, to the detriment of other national expressions of the genre. This period is key to the development of the genre in Britain, however, with the establishment of television as a popular medium incorporating the development of domestic science fiction television alongside the import of American products, together with the spread of the very term ‘science fiction’ through books, pulps and comics as well as radio, television and cinema. It was also the time of a backlash against the perceived threat of American soft cultural power embodied in the attractive shine of science fiction with its promise of a bright technological future. In particular, this chapter examines the significance of the relationship between the BBC television and radio services and the film production company Hammer, which was responsible for multiple adaptations of BBC properties, including a number of science fiction texts. The Hammer adaptation of the television serial The Quatermass Experiment proved to be the first major success for the company, moving it towards its most famous identity as producer of horror texts, though often horror with an underlying scientific element, as with their successful series of Frankenstein films. This chapter thus argues that the interaction between film and broadcast media in relation to science fiction was crucial at this historical juncture, not only in helping promote the identities of filmmakers like Hammer, but also in supporting the identity of the BBC and its properties, and in acting as a nexus for the then current debates on taste and national identity.

Relação homem e atmosfera sob a objectiva de novas tecnologias

Os métodos volumétricos de recolha de amostras de ar constituem os métodos dominantes atualmente para a monitorização de aeroalergenos, sendo a metodologia “Hírst” a dominante para a monitorização do pólen atmosférico. Recentemente têm surgido alguns avanços metodológicos nesta área combinando tecnologias bioquímicas e imunológicas pelo que se empreendeu este estudo a fim de comparar uma tecnologia “Ciclone”, desenvolvida no âmbito de um projeto europeu do programa LIFE (LIFE05 ENV/F/000068), com o referido método padrão quanto à eficiência de captação do pólen atmosférico e à deteção de aeroalergenos polínicos. Métodos: Foram efetuadas amostragens do conteúdo polínico atmosférico dos períodos de polinização dos anos 2006 e 2007 mediante um coletor tipo “Hirst” (Burkard® Seven Day Recording Volumetric Spore Trap®) e um coletor tipo “Ciclone” (AeoluS®, Coriolis ® da Bertin Technologies), colocados lado a lado. Foram instalados sobre uma plataforma meteorológica situada no centro da cidade de Évora, 17m acima do nível do solo. As amostras foram analisadas de acordo com os protocolos estabelecidos para cada método. De forma complementar foi realizada uma correlação dos dados obtidos com os registos de inquéritos sintomatológicos efetuados por voluntários das consultas externas de Imunoalergologia do hospital do Espírito Santo em Évora. Todos aqueles que apresentaram queixas respiratórias durante 0 período primaveril efetuaram testes cutâneos em “Prick” modificado aos aeroalergenos mais frequentes na região, a fim de se determinar o respetivo Perl de sensibilidades. Resultados: Esperou-se com este estudo testar a eficácia de uma nova metodologia para deteção e análise de bioaerossóis, comparativamente com a metodologia padrão e com a sua relação sintomatologia atópica respiratória. /ABSTRACT - Nowadays volumetric methods for bioaerosols sampling constitute the main methods to monitor the aeroallergens whereas “Hirst" methodology is the most dominant method to monitor airborne pollen. Recently some methodological advances have been introduced in this area matching biochemical and immunological technologies and so a study was accomplished in order to compare a "Cyclone” technology, developed under the scope of a European project - the LFE program -, with the mentioned standard method in terms of efficiency of airborne pollen sampling and detection of aeroallergens. Methods: Air samples from the outdoor environment were collected during the pollination period, along the year 2006 and 2007 with a "Hirst"-t3pe collector (Burkard® Seven Day Recording Volumetric Spore Trap®) and a "Cyclone"-type collector (Aeolus®, Coriolis® Bertin Technologies), placed side by side. They were installed on a meteorological platform situated at the center of Évora, 17m above ground level. Samples were analyzed according to the established protocols by each method. In a complementary way a data correlation was done between the symptomatologic inquiries fiom volunteers of the Immunoallergology external consultations at the Hospital Espírito Santo, in Évora. Everyone declaring breathing complaints during the spring season had done modified skin 'Trick" tests to the most usual aeroallergens of the region Results: It is waited from this study to test the efficiency of a new methodology for detection and analysis of bioaerossols, comparatively with the standard methodology and and its relation with the atopic simptomatologic breathing

Various Joyful Encounters with the Dystopias of Affective Capitalism

This article contends that what appear to be the dystopic conditions of affective capitalism are just as likely to be felt in various joyful encounters as they are in atmospheres of fear associated with post 9/11 securitization. Moreover, rather than grasping these joyful encounters with capitalism as an ideological trick working directly on cognitive systems of belief, they are approached here by way of a repressive affective relation a population establishes between politicized sensory environments and what Deleuze and Guattari (1994) call a brain-becoming-subject. This is a radical relationality (Protevi, 2010) understood in this context as a mostly nonconscious brain-somatic process of subjectification occurring in contagious sensory environments populations become politically situated in. The joyful encounter is not therefore merely an ideological manipulation of belief, but following Gabriel Tarde (as developed in Sampson, 2012), belief is always the object of desire. The discussion starts by comparing recent efforts by Facebook to manipulate mass emotional contagion to a Huxleyesque control through appeals to joy. Attention is then turned toward further manifestations of affective capitalism; beginning with the so-called emotional turn in the neurosciences, which has greatly influenced marketing strategies intended to unconsciously influence consumer mood (and choice), and ending with a further comparison between encounters with Nazi joy in the 1930s (Protevi, 2010) and the recent spreading of right wing populism similarly loaded with political affect. Indeed, the dystopian presence of a repressive political affect in all of these examples prompts an initial question concerning what can be done to a brain so that it involuntarily conforms to the joyful encounter. That is to say, what can affect theory say about an apparent brain-somatic vulnerability to affective suggestibility and a tendency toward mass repression? However, the paper goes on to frame a second (and perhaps more significant) question concerning what can a brain do. Through the work of John Protevi (in Hauptmann and Neidich (eds.), 2010: 168-183), Catherine Malabou (2009) and Christian Borch (2005), the article discusses how affect theory can conceive of a brain-somatic relation to sensory environments that might be freed from its coincidence with capitalism. This second question not only leads to a different kind of illusion to that understood as a product of an ideological trick, but also abnegates a model of the brain which limits subjectivity in the making to a phenomenological inner self or Being in the world.

Le cinéma d'animation : avènement d'une institution et naissance d'une industrie

Les premiers comptes rendus de l’histoire du cinéma ont souvent considéré les premiers dessins animés, ou vues de dessins animés, comme des productions différentes des films en prise de vue réelle. Les dessins animés tirent en effet leurs sources d’inspiration d’une gamme relativement différente d’influences, dont les plus importantes sont la lanterne magique, les jouets optiques, la féérie, les récits en images et les comics. Le dessin animé n’en demeure pas moins fondamentalement cinématographique. Les vues de dessins animés de la décennie 1900 ne se distinguent ainsi guère des scènes à trucs sur le plan de la technique et du style. D’abord le fait de pionniers issus de l’illustration comique et du croquis vivant comme Émile Cohl, James Stuart Blackton et Winsor McCay, le dessin animé s’industrialise au cours de la décennie 1910 sous l’impulsion de créateurs venant du monde des comics, dont John Randolph Bray, Earl Hurd, Paul Terry et Max Fleisher. Le processus d’institutionnalisation par lequel le dessin animé en viendra à être considéré comme une catégorie de film à part entière dépend en grande partie de cette industrialisation. Les studios de dessins animés développent des techniques et pratiques managériales spécifiquement dédiées à la production à grande échelle de films d’animation. Le dessin animé se crée ainsi sa propre niche au sein d’une industrie cinématographique dont il dépend toutefois toujours entièrement. Ce phénomène d’individuation repose sur des formules narratives et des personnages récurrents conçus à partir de modèles issus des comics des années 1910.

On Space-Time Trade-Off for Montgomery Multipliers over Finite Fields

La multiplication dans le corps de Galois à 2^m éléments (i.e. GF(2^m)) est une opérations très importante pour les applications de la théorie des correcteurs et de la cryptographie. Dans ce mémoire, nous nous intéressons aux réalisations parallèles de multiplicateurs dans GF(2^m) lorsque ce dernier est généré par des trinômes irréductibles. Notre point de départ est le multiplicateur de Montgomery qui calcule A(x)B(x)x^(-u) efficacement, étant donné A(x), B(x) in GF(2^m) pour u choisi judicieusement. Nous étudions ensuite l'algorithme diviser pour régner PCHS qui permet de partitionner les multiplicandes d'un produit dans GF(2^m) lorsque m est impair. Nous l'appliquons pour la partitionnement de A(x) et de B(x) dans la multiplication de Montgomery A(x)B(x)x^(-u) pour GF(2^m) même si m est pair. Basé sur cette nouvelle approche, nous construisons un multiplicateur dans GF(2^m) généré par des trinôme irréductibles. Une nouvelle astuce de réutilisation des résultats intermédiaires nous permet d'éliminer plusieurs portes XOR redondantes. Les complexités de temps (i.e. le délais) et d'espace (i.e. le nombre de portes logiques) du nouveau multiplicateur sont ensuite analysées: 1. Le nouveau multiplicateur demande environ 25% moins de portes logiques que les multiplicateurs de Montgomery et de Mastrovito lorsque GF(2^m) est généré par des trinômes irréductible et m est suffisamment grand. Le nombre de portes du nouveau multiplicateur est presque identique à celui du multiplicateur de Karatsuba proposé par Elia. 2. Le délai de calcul du nouveau multiplicateur excède celui des meilleurs multiplicateurs d'au plus deux évaluations de portes XOR. 3. Nous determinons le délai et le nombre de portes logiques du nouveau multiplicateur sur les deux corps de Galois recommandés par le National Institute of Standards and Technology (NIST). Nous montrons que notre multiplicateurs contient 15% moins de portes logiques que les multiplicateurs de Montgomery et de Mastrovito au coût d'un délai d'au plus une porte XOR supplémentaire. De plus, notre multiplicateur a un délai d'une porte XOR moindre que celui du multiplicateur d'Elia au coût d'une augmentation de moins de 1% du nombre total de portes logiques.

Factores asociados a la aparición de mediastinitis en revascularizacion miocárdica

Objetivos: La mediastinitis se presenta hasta en el 4% de los pacientes sometidos a revascularización miocárdica, con un mortalidad hospitalaria reportada del 14 al 47%, generando aumento en los costos de atención, deterioro de la calidad de vida y la sobrevida a largo plazo del enfermo; su etiología es multifactorial. El objetivo de este estudio fue determinar cuáles antecedentes clínicos del paciente y factores relacionados con el procedimiento quirúrgico se asocian con la aparición mediastinitis. Métodos: Diseño de casos y controles anidado en una cohorte histórica de pacientes sometidos a revascularización miocárdica en el periodo de enero de 2005 a julio de 2011. Los pacientes con mediastinitis se compararon con un grupo control sin mediastinitis tomados del mismo grupo de riesgo en una relación 1:4, y pareados por fecha de cirugía. El diagnóstico de mediastinitis se hizo con criterios clínicos, de laboratorio y hallazgos quirúrgicos. Resultados: Se identificaron 30 casos en ese periodo. Los factores asociados a la aparición del evento fueron: Diabetes Mellitus OR 2,3 (1.1- 4,9), uso de circulación extracorpórea OR 2,4 (1,1 -5.5), tiempo de perfusión OR 1,1 (1,1 – 1.3) y pacientes mayores de 70 años OR 1.1 (1,2-1-4). Conclusiones: La mediastinitis sigue siendo una complicación de baja prevalencia con consecuencias devastadoras. El impacto clínico y económico de esta complicación debe obligar a los grupos quirúrgicos a crear estrategias de prevención con base en el conocimiento de los factores de riesgo de su población.

The cytoprotective effect of alpha-tocopherol and daidzein against d-galactosamine-induced oxidative damage in the rat liver

We hypothesized that the hepatotoxicity that develops after the induction of oxidative stress (induced by d-galactosamine [GalN]) can be ameliorated by alpha-tocopherol (ATC) and the soy isoflavone daidzein. To test this, we ranked and assigned male Wistar rats into 6 groups, which involved pretreatment (ATC or daidzein) for 1 hour followed by treatment (GalN) for 23 hours. Histopathologic analysis showed that GalN administration induced marked necrosis (P < .001), steatosis (P < .001), both lobular and portal inflammations (P < .001), overall histopathologic score (P < .001), and activation of caspase-3 in the liver (P < .001). Immunohistochemical staining of malondialdehyde-protein adducts, a measure of oxidative stress, was increased in response to GalN (P < .001). Paradoxically, there were increases in total (P < .05) and cytosolic superoxide dismutase (P < .001) activities after GalN administration, indicative of an up-regulation of antioxidant defenses. The concentration of total protein (P < .001), albumin (P < .01), and globulin fractions (P < .001) in the plasma, as well as the activity of aspartate aminotransferase (P < .001), was significantly perturbed after GalN treatment, reflective of overall acute hepatic injury. Administration of daidzein showed a significant amelioration of the Ga1N-induced increase in malondialdehyde-protein adducts (P < .01) and cytosolic superoxide dismutase activities (P < .01) in the liver. However, all other variables were not significantly altered in response to daidzein. In response to ATC pretreatment, the total histopathologic score (P < .05), degree of necrosis (P < .05), and both lobular (P < .05) and portal (P = .05) inflammations were significantly ameliorated. To conclude, both daidzein and ATC protect the liver against oxidative damage possibly via different pathways.

QoS evaluation of bandwidth schedulersin IPTV networks offered SRD fluidvideo traffic: a simulation study

IPTV is now offered by several operators in Europe, US and Asia using broadcast video over private IP networks that are isolated from Internet. IPTV services rely ontransmission of live (real-time) video and/or stored video. Video on Demand (VoD)and Time-shifted TV are implemented by IP unicast and Broadcast TV (BTV) and Near video on demand are implemented by IP multicast. IPTV services require QoS guarantees and can tolerate no more than 10-6 packet loss probability, 200 ms delay, and 50 ms jitter. Low delay is essential for satisfactory trick mode performance(pause, resume,fast forward) for VoD, and fast channel change time for BTV. Internet Traffic Engineering (TE) is defined in RFC 3272 and involves both capacity management and traffic management. Capacity management includes capacityplanning, routing control, and resource management. Traffic management includes (1)nodal traffic control functions such as traffic conditioning, queue management, scheduling, and (2) other functions that regulate traffic flow through the network orthat arbitrate access to network resources. An IPTV network architecture includes multiple networks (core network, metronetwork, access network and home network) that connects devices (super head-end, video hub office, video serving office, home gateway, set-top box). Each IP router in the core and metro networks implements some queueing and packet scheduling mechanism at the output link controller. Popular schedulers in IP networks include Priority Queueing (PQ), Class-Based Weighted Fair Queueing (CBWFQ), and Low Latency Queueing (LLQ) which combines PQ and CBWFQ.The thesis analyzes several Packet Scheduling algorithms that can optimize the tradeoff between system capacity and end user performance for the traffic classes. Before in the simulator FIFO,PQ,GPS queueing methods were implemented inside. This thesis aims to implement the LLQ scheduler inside the simulator and to evaluate the performance of these packet schedulers. The simulator is provided by ErnstNordström and Simulator was built in Visual C++ 2008 environmentand tested and analyzed in MatLab 7.0 under windows VISTA.
