Stereoscope

Wheatstone’s stereoscope placed two mirrors on either side that were mounted at a right angle in order to view the two dissimilar drawings presented (Hankins 148). There are two identical monocular tubes that allow each eye to view the images (Hankins 148). Each eye views the image it was intended to see. The two eyes see slightly different images through this binocular vision (Hankins 148). The combination of the two images creates this illusion of depth and solidarity through their superimposition (Hankins 154). In order to view these images, the eyes were covered from all external light (Clay 152). The stereoscope was first seen as a philosophical toy along with other inventions such as the zoetrope, providing entertainment as well as scientific insight (Hankins 148). The stereoscope above is more similar to the “Holmes Stereoscope”, which transformed Wheatstone’s stereoscope into a handheld version that could be put on a stand (Hawkins 155). He replaced the retina of the eye with a sensitive plate; therefore, the lenses acted as the eyes (Silverman 738). In the video, an embellishment adorns the bottom of the stand that holds up the binocular lens and the images. The lenses are in a wooden frame that has an attached stand that holds the slides of images. There also is a knob on the side of the device that can adjust the lens on the two monocular tubes (Bokander 485).

Smashing the Mirror of Yamato: Sakaguchi Ango, Decadence & a Postmetaphysical Buddhist Critique of Culture

This article focuses on several key philosophical themes in the criticism of Sakaguchi Ango (1906–1955), one of postwar Japan’s most influential and controversial writers. Associated with the underground Kasutori culture as well as the Burai-ha of Tamura Taijirō (1911–1983), Oda Sakunosuke (1913–1947) and Dazai Osamu (1909–1948), Ango gained fame for two provocative essays on the theme of daraku or “decadence”—Darakuron and Zoku darakuron—pubished in 1946, in the wake of Japan’s traumatic defeat and the beginnings of the Allied Occupation. Less well-known is the fact that Ango spent his student years studying classical Buddhist texts in Sanskrit, Pali and Tibetan, and that he at at one time aspired to the priesthood. The article analyses the concept of daraku in the two essays noted above, particularly as it relates to Ango’s vision of a refashioned morality based on an interpretation of human subjectivity vis-à-vis the themes of illusion and disillusion. It argues that, despite the radical and modernist flavor of Ango’s essays, his “decadence” is best understood in terms of Mahāyāna and Zen Buddhist concepts. Moreover, when the two essays on decadence are read in tandem with Ango’s wartime essay on Japanese culture (Nihon bunka shikan, 1942), they form the foundation for a “postmetaphysical Buddhist critique of culture,” one that is pragmatic, humanistic, and non-reductively physicalist.

The sense of the body in individuals with spinal cord injury

Increasing evidence suggests that the basic foundations of the self lie in the brain systems that represent the body. Specific sensorimotor stimulation has been shown to alter the bodily self. However, little is known about how disconnection of the brain from the body affects the phenomenological sense of the body and the self. Spinal cord injury (SCI) patients who exhibit massively reduced somatomotor processes below the lesion in the absence of brain damage are suitable for testing the influence of body signals on two important components of the self-the sense of disembodiment and body ownership. We recruited 30 SCI patients and 16 healthy participants, and evaluated the following parameters: (i) depersonalization symptoms, using the Cambridge Depersonalization Scale (CDS), and (ii) measures of body ownership, as quantified by the rubber hand illusion (RHI) paradigm. We found higher CDS scores in SCI patients, which show increased detachment from their body and internal bodily sensations and decreasing global body ownership with higher lesion level. The RHI paradigm reveals no alterations in the illusory ownership of the hand between SCI patients and controls. Yet, there was no typical proprioceptive drift in SCI patients with intact tactile sensation on the hand, which might be related to cortical reorganization in these patients. These results suggest that disconnection of somatomotor inputs to the brain due to spinal cord lesions resulted in a disturbed sense of an embodied self. Furthermore, plasticity-related cortical changes might influence the dynamics of the bodily self.

The Representation of Motherhood in Polish Cinema

The project aimed to analyse representations of motherhood in Polish cinema as a special case of a more general system within the representation of women. It concentrated on the image of the Polish Mother created during the 19th century in Polish culture under the influence of specific political, social and religious factors. Ms. Ostrowska's initial hypothesis was that this symbolic image became one of the most stable elements in Polish cinema and as her research revealed, it was valuable for the preservation of national identity but nevertheless a fiercely constraining model for Polish femininity. In order to fully understand the nature of this persistent image it was initially necessary to related it to broader contexts and issues in representation. These included the image of the Polish Mother within general mythological structures (using the notion of myth in the Barthesian sense). Following her initial research Ms. Ostrowska felt that it was most appropriate to view the myth of the Polish Mother as a dominant ideological structure in the discourse of motherhood within Polish culture. An analysis of the myth of the Polish Mother can provide an insight into how Polish society sees itself at different periods in time and how a national identity was constructed in relation to particular ideological demands stemming from concrete historical and political situations. The analysis of the film version of this myth also revealed some aspects of the national character of Polish cinema. There the image of woman has become enshrined as the "eternal feminine", with virtues which are inevitably derived directly from Catholicism, particularly in relation to the networks of meanings around the central figure of Mary, Mother of God. In 19th century Poland these were linked with patriotic values and images of woman became part of the defence of the very idea of Poland and Polishness. After World War Two, this religious-political image system was adapted to the demands of the new communist ideology. The possibility of manipulating the ideological dimensions of the myth of the Polish Mother is due to the very nature of the image, which as a symbol of civil religion had been able to function independently of any particular state or church institution. Although in communist ideology the stress was on the patriotic aspect of the myth, its pronounced religious aspect was also transmitted, consciously or not, in the denotation process, this being of great significance in the viewer's response to the female character. This appropriation of elements derived from the national patriotic tradition into the discourse of communist ideology was a very efficient strategy to establish the illusion of continuity in national existence, which was supposed to convince society of the rightness of the new political situation. The analysis of films made in the post-war period showed the persistence of this discourse on motherhood in a range of cinematic texts regardless of the changing political situation. Ms. Ostrowska claims that the stability of this discursive formation is to a certain extent the result of the mythological aspect of the mother figure. This mythological structure also belongs to the ideology of Romanticism which in general continues to prevail in Polish cultural discourse as a meta-language of national community. The analysis of the films confirmed the hypothesis of the Polish Mother as a myth-sign whose signifier is stable whereas the signified depends on the specific historical conditions in which it is set. Therefore in the famous propaganda documentary Kobiety naszych dni (Women of Our Days, 1951) by Jan Zelnik, and in other films made after the October 1956 "thaw" it functions as an "empty sign. She concludes that it would be difficult to deny that the myth of the Polish Mother has offered Polish women a special role in national life, granting them a high moral position in the social, hierarchy. However the processes of idealisation involved have resulted in a deprivation of her subjectivity and the right to decide about her own life. This idealisation also served to strengthen traditional patriarchal structures through this set of female obligations to the mother land. In Polish ideology it is not a man who demands sacrifice from a woman but the motherland, which, deprived of the institutions of male power for nearly 150 years, had functioned as a feminine structure. That is why oppressive aspects of the myth have been obscured for so long. While Polish women were doubtless able to accept the constrictions because of their sense of national duty and any misgivings were overridden by the argument of the cause, it is important to recognise that the strength of these constructions, compounded by the ways in which they spoke of and continue to speak of a certain perfection, make them persist into contemporary Poland. Poland is however no longer embattled and the signs that made these meanings are potentially empty. This space for meaning will be and is already being contested and increasingly colonised by current western models of femininity. Ms. Ostrowska's final question is whether this will help to prevent a possible resentful victimisation of the silent and noble Polish Mother.

Traditionen, Utopien, Dekonstruktionen - die Sozialstaatskonzepte des 'Ostblocks' (1945-1990)

The welfare state concepts in Eastern Europe under state socialism (1945-1990) were based on the conviction that only the state was responsible for solving all social problems. The 'bourgeois' manners of individual care were substituted by general measures in the field of labour- and family politics, as well as urban development. The experience showed however that this way of substitution was an illusion, because certain target groups were still in need of help (for example ill or handicapped children and adults, elderly people etc). Nevertheless, most of the Eastern European countries - with the exception of Yugoslavia - decided to abolish the existing forms of professional social work and the training for social workers. Instead, they invented 'surrogate structures' to manage the care for the 'needy': Various institutions and occupational groups (schools, hospitals and ambulances, employees groups etc.) took over the tasks of social workers and were trained to fulfil this as a kind of 'social practice'. Therefore, it is wrong to claim that social work was completely abolished under state socialism, But: as social work 'as such' did not exist any longer, it is more reasonable to speak of welfare state concepts, including social policy on one hand, and non- or paraprofessional social practice on the other. To characterize the effect of these welfare state concepts three parameter of interpretation seem to be useful: 'traditions', 'visions', and 'deconstructions' - embedded in a system of repression as well as incentives. Traditions: The huge 'social laboratory' that was installed was not a totally new one - it still carried on the heritage of the bygone: some bourgeois traces as well as elements out of the fascist heritage and -last but not least - the traditions of their own socialist movement. Visions: The socialist traditions included visions of social justice, the creation of a 'new mankind', a classless society, the end of exploitation and a peaceful living together of all people. Although the 'real existing socialism' has destroyed most of these visions, the power of these utopian ideas has outshined a lot of the every day’s misfortune and injustice for quite a long time. Deconstructions: The term of 'deconstruction' has a threefold meaning: the deconstruction of professional welfare, the deconstruction - in the sense of reinterpretation - of the socialist ideals such as social justice and social security, making an instrument of inclusion and exclusion out of it. And the deconstruction that is necessary to free the history of social work under state socialism from the prejudices and distorting practices, from both sides, the east and the west. In the contribution these three parameter of interpretation are applied on the following issues: The gaps in the 'overall system' of social security; working morale and education for work; mass organisations as an instrument of egalitarianism and general prevention; de-professionalisation by 'surrogating' social work; the 'transparent client'; church as refuge or 'state organ'; women’s politics as bio-politics.

Subsecond changes of global brain state in illusory multistable motion perception

This study explored transient changes in EEG microstates and spatial Omega complexity associated with changes in multistable perception. 21-channel EEG was recorded from 13 healthy subjects viewing an alternating dot pattern that induced illusory motion with ambiguous direction. Baseline epochs with stable motion direction were compared to epochs immediately preceding stimuli that were perceived with changed motion direction ('reference stimuli'). About 750 ms before reference stimuli, Omega complexity decreased as compared to baseline, and two of four classes of EEG microstates changed their probability of occurrence. About 300 ms before reference stimuli, Omega complexity increased and the previous deviations of EEG microstates were reversed. Given earlier results on Omega complexity and microstates, these sub-second EEG changes might parallel longer-lasting fluctuations in vigilance. Assumedly, the discontinuities of illusory motion thus occur during sub-second dips in arousal, and the following reconstruction of the illusion coincides with a state of relative over-arousal.

Real Walking through Virtual Environments by Redirection Techniques

We present redirection techniques that support exploration of large-scale virtual environments (VEs) by means of real walking. We quantify to what degree users can unknowingly be redirected in order to guide them through VEs in which virtual paths differ from the physical paths. We further introduce the concept of dynamic passive haptics by which any number of virtual objects can be mapped to real physical proxy props having similar haptic properties (i. e., size, shape, and surface structure), such that the user can sense these virtual objects by touching their real world counterparts. Dynamic passive haptics provides the user with the illusion of interacting with a desired virtual object by redirecting her to the corresponding proxy prop. We describe the concepts of generic redirected walking and dynamic passive haptics and present experiments in which we have evaluated these concepts. Furthermore, we discuss implications that have been derived from a user study, and we present approaches that derive physical paths which may vary from the virtual counterparts.

Dutch boundaries

In many schools of architecture the 1970s have been an important watershed for the way in which architecture was taught. For example, recent studies have stressed the importance of Aldo Rossi for the changes in the teaching of architec-ture at the ETH in Zürich that before was based on orthodox modern principles. A similar struggle between an orthodox conception of modernity and its criticism took place at the architectural faculty of Delft, in the Netherlands. Although Delft is an important European school of architecture, the theoretical work produced during this period is not largely known outside the Netherlands. This is perhaps due to the fact that most studies were published in Dutch. With this article, I intend to make the architectural theory developed during this period known to a larger public. The article describes the intellectual journey made by Dutch stu-dents of architecture in the 1970s and 1980s. This was the quest to receive recognition for the intellectual substance of architecture: the insight architecture could be a discourse and a form of knowledge and not only a method of building. Specifically, the work of the architectural theoretician Wim Nijenhuis is highlight-ed. However, as I point out in this article, the results of this journey also had its problematic sides. This becomes clear from the following sentence taken from the dissertation of Wim Nijenhuis: "The search for metaphysical fiction and the tendency towards a technological informed absolute through fully transparent and simultaneous information, should be contested by a fantasy dimension, that does not wish to 'overcome' a given situation and that does not rely on 'creativi-ty' (that would still be historical and humanistic)." Texts like this have a hermet-ic quality that is not easy to comprehend for an architectural public. Even more, there is an important debate looming behind these sentences. As an important outcome of their quest the architectural students in Delft asked themselves: how do we give form to architectural theory once its claim to truth is exposed as an illusion? For Nijenhuis, the discourse about architecture is a mere 'artful game with words': a fiction, besides other forms of fiction like poetry or literature. The question is then if we have not entered the realm of total subjectivity and relativ-ism with this position. From what can the discourse of architecture derive its authority after the death of God?

"Coaching soccer is a man’s job!" – The influence of gender stereotypes on structures for recruiting female coaches in soccer clubs

Statistics published by the German Football Association indicate that women are significantly under-represented amongst soccer coaches, especially in the amateur leagues. In this paper we analyse how gender stereotypes influence the structural conditions surrounding the recruitment of coaches to soccer clubs that contribute to the exclusion of women from coaching positions. A qualitative study of five selected soccer clubs which are members of a German regional soccer association reveals that informal and personal decision-making practices still play a fundamental role in the recruitment of coaches. These practices undermine formal guidelines and give disproportionate weight to stereotyped preferences in the recruitment of soccer coaches. In this context, decision-makers' (functionaries') professed support of women largely serves a symbolic purpose and creates an illusion of equality concerning decisions that have already been taken at an informal level.

The Neural Substrates of Multisensory Speech Perception

Comprehending speech is one of the most important human behaviors, but we are only beginning to understand how the brain accomplishes this difficult task. One key to speech perception seems to be that the brain integrates the independent sources of information available in the auditory and visual modalities in a process known as multisensory integration. This allows speech perception to be accurate, even in environments in which one modality or the other is ambiguous in the context of noise. Previous electrophysiological and functional magnetic resonance imaging (fMRI) experiments have implicated the posterior superior temporal sulcus (STS) in auditory-visual integration of both speech and non-speech stimuli. While evidence from prior imaging studies have found increases in STS activity for audiovisual speech compared with unisensory auditory or visual speech, these studies do not provide a clear mechanism as to how the STS communicates with early sensory areas to integrate the two streams of information into a coherent audiovisual percept. Furthermore, it is currently unknown if the activity within the STS is directly correlated with strength of audiovisual perception. In order to better understand the cortical mechanisms that underlie audiovisual speech perception, we first studied the STS activity and connectivity during the perception of speech with auditory and visual components of varying intelligibility. By studying fMRI activity during these noisy audiovisual speech stimuli, we found that STS connectivity with auditory and visual cortical areas mirrored perception; when the information from one modality is unreliable and noisy, the STS interacts less with the cortex processing that modality and more with the cortex processing the reliable information. We next characterized the role of STS activity during a striking audiovisual speech illusion, the McGurk effect, to determine if activity within the STS predicts how strongly a person integrates auditory and visual speech information. Subjects with greater susceptibility to the McGurk effect exhibited stronger fMRI activation of the STS during perception of McGurk syllables, implying a direct correlation between strength of audiovisual integration of speech and activity within an the multisensory STS.

Virtual reality and the role of the prefrontal cortex in adults and children

In this review, the neural underpinnings of the experience of presence are outlined. Firstly, it is shown that presence is associated with activation of a distributed network, which includes the dorsal and ventral visual stream, the parietal cortex, the premotor cortex, mesial temporal areas, the brainstem and the thalamus. Secondly, the dorsolateral prefrontal cortex (DLPFC) is identified as a key node of the network as it modulates the activity of the network and the associated experience of presence. Thirdly, children lack the strong modulatory influence of the DLPFC on the network due to their unmatured frontal cortex. Fourthly, it is shown that presence-related measures are influenced by manipulating the activation in the DLPFC using transcranial direct current stimulation (tDCS) while participants are exposed to the virtual roller coaster ride. Finally, the findings are discussed in the context of current models explaining the experience of presence, the rubber hand illusion, and out-of-body experiences.

Performing ‘Readings’: The Interplay of Theatre And Digital Comics In Tezuka

The article investigates the intriguing interplay of digital comics and live-action elements in a detailed performance analysis of TeZukA (2011) by choreographer Sidi Larbi Cherkaoui. This dance theatre production enacts the life story of Osamu Tezuka and some of his famous manga characters, interweaving performers and musicians with large-scale projections of the mangaka’s digitised comics. During the show, the dancers perform different ‘readings’ of the projected manga imagery: e.g. they swipe panels as if using portable touchscreen displays, move synchronously to animated speed lines, and create the illusion of being drawn into the stories depicted on the screen. The main argument is that TeZukA makes visible, demonstrates and reflects upon different ways of delivering, reading and interacting with digital comics. In order to verify this argument, the paper uses ideas developed in comics and theatre studies to draw more specifically on the use of digital comics in this particular performance.
