La ballerine illettrée:transformations of the feminine in Mallarmé's sance writings

Stéphane Mallarmé's texts on dance criticism occupy a prominent place in dance literature. They have also been of major interest to the Mallarme specialists who have seen in them the key to a greater understanding of the whole of his work. In this article I determine how his dance writings can be interpreted in the context of the whole of the œuvre, including for example the women's magazine he wrote and produced, La Dernière Mode. I establish to what extent the female presence in Mallarmé's poetry tends towards metaphors, women's bodies absent or negated by the gaze of the poet. As the poet responds to the stimulus of the dance, he divests the female dancer of her womanly characteristics, recasting her in his own imagination both as feminine principle and incarnation of 'l'Idée', and also as mythical being, 'au-delà de toute vie possible', a composite of other female characters inhabiting his œuvre, constantly poised between presence and absence, stillness and movement, a locus for a precarious balance which is endlessly re-enacted in h.is own writing practice.

Shining in the center:central gaze cascade effect on product choice

Consumers' tendency to choose the option in the center of an array and the process underlying this effect is explored. Findings from two eye-tracking studies suggest that brands in the horizontal center receive more visual attention. They are more likely to be chosen. Investigation of the attention process revealed an initial central fixation bias, a tendency to look first at the central option, and a central gaze cascade effect, progressively increasing attention focused on the central option right prior to decision. Only the central gaze cascade effect was related to choice. An offline study with tangible products demonstrated that the centrally located item within a product category is chosen more often, even when it is not placed in the center of the visual field. Despite widespread use, memory-based attention measures were not correlated with eye-tracking measures. They did not capture visual attention and were not related to choice. © 2012 by JOURNAL OF CONSUMER RESEARCH, Inc.

Pathological changes in the primary visual cortex (Area V1) in Creutzfeldt-Jakob syndrome

About 10% of patients with Creutzfeldt-Jakob syndrome (disease) (CJD) exhibit visual symptoms at presentation and approximately 50% during the course of the disease. The objectives of the present study were to determine, in two subtypes of CJD, viz., sporadic CJD (sCJD) and variant CJD (vCJD), the degree of pathological change in the primary visual cortex (area V1) and the extent to which pathology in V1 may influence visual function. The vacuolation (‘spongiform change’), surviving neurons, glial cell nuclei, and deposits of prion protein (PrP) were quantified in V1 obtained post-mortem in nine cases of sCJD and eleven cases of vCJD. In sCJD, the vacuoles and PrP deposits were regularly distributed along the cortex parallel to the pia mater in clusters with a mean dimension from 450 to 1000 µm. Across the cortex, the vacuolation was most severe in laminae II/III and the glial cell reaction in laminae V/VI. Surviving neurons were most abundant in laminae II/III while PrP deposition either affected all laminae equally or was maximal in lamina II/III. In vCJD, the vacuoles and diffuse PrP deposits were distributed relatively uniformly parallel to the pia mater while the florid deposits were consistently distributed in regular clusters. Across V1, the vacuoles either exhibited a bimodal distribution or were uniformly distributed. The diffuse PrP deposits occurred most frequently in laminae II/III while the florid deposits were more generally distributed. The data suggest that in both sCJD and vCJD, pathological changes in area V1 may affect the processing of visual information in laminae II/III and its transmission from V1 to V2 and to subcortical visual areas. In addition, the data suggest an association in sCJD between the developing pathology and the functional domains of V1 while in vCJD the pathology is more uniformly distributed. These changes could be a factor in the development of poor visual acuity, visual field defects, cortical blindness, diplopia, and vertical gaze palsy that have been observed in Creutzfeldt-Jakob syndrome.

Characteristics of visual function in Asperger’s syndrome and the autism spectrum

Autism is a pervasive developmental disorder and Asperger’s syndrome is part of the spectrum of autism disorders. This thesis aims to: • Review and investigate current theories concerning visual function in individuals with Asperger’s syndrome and high functioning autism spectrum disorder and to translate the findings into clinical practice by developing a specific protocol for the eye examination of individuals of this population. • Investigate whether those with Asperger’s syndrome are more likely to suffer from Meares-Irlen syndrome and/or dyslexia. • Assess the integrity of the M-cell pathway in Asperger’s syndrome using perimetric tests available in optometric practice to investigate and also to describe the nature of any defects. • Evaluate eye movement strategies in Asperger’s whilst viewing both text and images. Also to evaluate the most appropriate methodology for investigating eye movements; namely optical digital eye tracking and electrophysiology methodologies. Findings of the investigations include • Eye examinations for individuals with Asperger’s syndrome should contain the same testing methods as for the general population, with special consideration for clear communication. • There is a depression of M-pathway visual field sensitivity in 57% (8/14) of people with Asperger’s syndrome, supporting previous evidence for an M-cell deficit in some individuals. • There is a raised prevalence of dyslexia in Asperger’s syndrome (26% of a sample of 31) but not necessarily of Meares-Irlen syndrome. • Gaze strategies are abnormal in Asperger’s syndrome, for both reading and viewing of images. With increased saccadic movement and decreased viewing of faces in comparison to background detail.

The vision strategy of golf putting

Golfers, coaches and researchers alike, have all keyed in on golf putting as an important aspect of overall golf performance. Of the three principle putting tasks (green reading, alignment and the putting action phase), the putting action phase has attracted the most attention from coaches, players and researchers alike. This phase includes the alignment of the club with the ball, the swing, and ball contact. A significant amount of research in this area has focused on measuring golfer’s vision strategies with eye tracking equipment. Unfortunately this research suffers from a number of shortcomings, which limit its usefulness. The purpose of this thesis was to address some of these shortcomings. The primary objective of this thesis was to re-evaluate golfer’s putting vision strategies using binocular eye tracking equipment and to define a new, optimal putting vision strategy which was associated with both higher skill and success. In order to facilitate this research, bespoke computer software was developed and validated, and new gaze behaviour criteria were defined. Additionally, the effects of training (habitual) and competition conditions on the putting vision strategy were examined, as was the effect of ocular dominance. Finally, methods for improving golfer’s binocular vision strategies are discussed, and a clinical plan for the optometric management of the golfer’s vision is presented. The clinical management plan includes the correction of fundamental aspects of golfers’ vision, including monocular refractive errors and binocular vision defects, as well as enhancement of their putting vision strategy, with the overall aim of improving performance on the golf course. This research has been undertaken in order to gain a better understanding of the human visual system and how it relates to the sport performance of golfers specifically. Ultimately, the analysis techniques and methods developed are applicable to the assessment of visual performance in all sports.

Eye movement problems and differential diagnosis of the parkinsonian syndromes

Differential clinical diagnosis of the parkinsonian syndromes, viz., Parkinson’s disease (PD), progressive supranuclear palsy (PSP), dementia with Lewy bodies (DLB), and multiple system atrophy (MSA) can be difficult. Eye movement problems, however, are a chronic complication of many of these disorders and may be a useful aid to diagnosis. Hence, the presence in PSP of vertical supranuclear gaze palsy, fixation instability, lid retraction, blepharospasm, and apraxia of eyelid opening and closing is useful in separating PD from PSP. Moreover, atypical features of PSP include slowing of upward saccades, moderate slowing of downward saccades, the presence of a full range of voluntary vertical eye movements, a curved trajectory of oblique saccades, and absence of square-wave jerks. Downgaze palsy is probably the most useful diagnostic clinical symptom of PSP. By contrast, DLB patients are specifically impaired in both reflexive and saccadic execution and in the performance of more complex saccadic eye movement tasks. Problems in convergence in DLB are also followed by akinesia and rigidity. Abnormal ocular fixation may occur in a significant proportion of MSA patients along with excessive square-wave jerks, a mild supranuclear gaze palsy, a gaze-evoked nystagmus, a positioning down-beat nystagmus, mild-moderate saccadic hypometria, impaired smooth pursuit movements, and reduced vestibulo-ocular reflex (VOR) suppression. There may be considerable overlap between the eye movement problems characteristic of the various parkinsonian disorders, but taken together with other signs and symptoms, can be a useful aid in differential diagnosis, especially in the separation of PD and PSP.

Empowering, degrading or a 'mutually exploitative' exchange For women?: Characterising the power relations of the strip club

This paper seeks to characterise the gendered and sexualised power relations of both female and male strip clubs, and to signal what this means for establishing positive definitions of female desire. It is argued that while it is not useful to present female strippers, or female patrons of male strip clubs as purely passive victims of male heterosexism within these venues, it is equally damaging to assume that these venues represent a whole-scale challenge to conventional oppressive gender and sexual relations for women. Some research has even suggested that both strippers and their patrons are engaged in a 'mutually exploitative' power relationship. Moreover, further empirical research documents key points where female dancers have perhaps wielded 'more' power over patrons at certain moments, and female dancers have highlighted feelings of empowerment and highlighted potential for gender and sexual relations which position women as passive to be subverted within stripping. However, such feelings are often temporally specific and are not applicable to all women in the strip industry. It may be particularly hard for these to manifest in women concentrated in the least economically-rewarding areas of the industry who have less 'power' to resist compromising their bodily boundaries. Furthermore, it is argued that women watching male strippers does little to reverse the 'male gaze', and nor does this male occupation carry as much negative social stigma with it as female stripping suffers. It is thus argued that the overwhelming picture, stemming largely from accounts of former dancers and from empirical studies of individual clubs, suggests these venues in fact do very little to challenge normative hetero-oppressive sexual scripts.

Center of shelf attention:understanding the role of visual attention on product choice

Two eye-tracking studies and an offline experiment explored the effect of central shelf location on attention and choice. Investigation of the attention process revealed that the central gaze cascade effect, progressively increasing attention focused on the central option predicted choice.

Comparison of fitting stability of the different soft toric contact lenses

Purpose: To compare lens orientation and rotational recovery of five currently available soft toric lenses. Methods: Twenty subjects were recruited and trialed with each of the study lenses in a random order. Study lenses were PureVision® Toric (B&L), Air Optix® for Astigmatism (Alcon), Biofinity® Toric (CooperVision), Acuvue® Advance for Astigmatism (Vistakon), and Proclear® Toric (CooperVision). Lens orientation in primary position to determine the lens rotation form the vertical position and rotational recovery to primary gaze orientation following a 45° manual misorientation for the different lenses was compared. Results: The Biofinity Toric showed the lowest rotation from the vertical position and the Proclear Toric the highest. Also, the highest and the lowest reorientation speed were related to the Biofinity Toric and the Acuvue Advance for Astigmatism, respectively. The Repeated Measures ANOVA showed a significant difference in the lens rotation (P=. 0.004) and rotational recovery (P<. 0.001) among different contact lenses and the performed multiple comparisons indicated differences in rotation and also in reorientation speed were only seen between the Biofinity Toric when compared to four other lenses (P<. 0.05). Conclusion: Although there was appropriate fitting, based upon lens orientation and reorientation speed, with each of the study lenses it would appear that the optimized ballast technique used in the design of the Biofinity Toric helps reduce lens rotation and improve rotational recovery compared to others.

Foveation time measure in Congenital Nystagmus through second order approximation of the slow phases

Congenital Nystagmus (CN) is an ocular-motor disorder characterised by involuntary, conjugated ocular oscillations, and its pathogenesis is still unknown. The pathology is de fined as "congenital" from the onset time of its arise which could be at birth or in the first months of life. Visual acuity in CN subjects is often diminished due to nystagmus continuous oscillations, mainly on the horizontal plane, which disturb image fixation on the retina. However, during short periods in which eye velocity slows down while the target image is placed onto the fovea (called foveation intervals) the image of a given target can still be stable, allowing a subject to reach a higher visual acuity. In CN subjects, visual acuity is usually assessed both using typical measurement techniques (e.g. Landolt C test) and with eye movement recording in different gaze positions. The offline study of eye movement recordings allows physicians to analyse nystagmus main features such as waveform shape, amplitude and frequency and to compute estimated visual acuity predictors. This analytical functions estimates the best corrected visual acuity using foveation time and foveation position variability, hence a reliable estimation of this two parameters is a fundamental factor in assessing visual acuity. This work aims to enhance the foveation time estimation in CN eye movement recording, computing a second order approximation of the slow phase components of nystag-mus oscillations. About 19 infraredoculographic eye-movement recordings from 10 CN subjects were acquired and the visual acuity assessed with an acuity predictor was compared to the one measured in primary position. Results suggest that visual acuity measurements based on foveation time estimation obtained from interpolated data are closer to value obtained during Landolt C tests. © 2010 IEEE.
