Unveiling and Revealing the Mirror: Mobile Reverberations in Patrick Bokanowski’s Animated Films

The principal focus of this article is to provide an analysis of some of the most significant works by the independent filmmaker Patrick Bokanowski and the methodology he uses to create those animated films. It addresses Bokanowski’s technique of filming on various kinds of reflective surfaces as a strategy for transforming the image through optical deformation and thereby expressing his subjective vision in films and animation. He explores the practical application of creating reverberation as visual echoes, as well as the use of unusual reflections that appear in mirrors and other more unstable reflective surfaces, such as liquid mercury, and the refraction occurring in sculpted lenses, glass or water. The aim of this strategy is the pure expression of subjective experience, with the director using a camera as if it were an entirely free-moving paintbrush that inspires creativity and breaks loose from automatic camera movements. Accordingly, this study examines the dynamic, expressive potential of the language of catoptrics, taking as paradigmatic examples two of Bokanowski’s short films: La Plage (1992) and Au bord du lac (1994). The authors’ analyses of these films are aimed at demonstrating how the artist manages to bring about qualitative, transformative changes of forms and space by reflecting images on mirrors, ripples in mercury and movements of water, and by combining these elements. The system developed by Bokanowski successfully transports us to an ever-changing, poetic universe and breaks new ground in the field of animation.

Ictal High-Frequency Oscillation for Lateralizing Patients With Suspected Bitemporal Epilepsy Using Wavelet Transform and Granger Causality Analysis.

Identifying lateralization of bilateral temporal lobe epilepsy (TLE) is a challenging issue; scalp electroencephalography (EEG) and routine band electrocorticography (ECoG) fail to reveal the epileptogenic focus for further temporal lobectomy treatment. High-frequency oscillations (HFOs) can be utilized as a biomarker for lateralizing the onset zone in suspected bitemporal epilepsy. Except subjective vision detect the HFOs, objective verification should be performed to raise the accuracy. In the present research, we prospectively studied 10 patients with refractory temporal seizures and who underwent ECoG with wide-band frequency amplifiers (2,048 Hz); all patients had a class I outcome after temporal resection. Pre- and ictal HFOs will be analyzed by wavelet transform (WT) and Granger causality (GC) to objectively verify lateralization of the seizure onset zone (SOZ). WT analysis showed ictal HFOs in 10 patients mainly covered from 80 to 115 Hz (average, 92.59 ± 10.23 Hz), and there was distinct bandpass boundary between pre-ictal HFOs and ictal HFOs. GC analysis showed five patients (2, 4, 5, 6, and 7), no matter the pre-ictal or ictal state, had the highest GC degree in SOZ itself. The remaining patients (1, 3, 8, 9, and 10) had the highest GC degree in SOZ with its adjacent regions in the pre-ictal and ictal stages. GC analysis further confirmed the result of the WT and suggested HFOs are initiated and propagated in the local brain region mainly, afterward, transmitting to adjacent brain regions. These results indicated that the combination of WT and GC analyses significantly contributes to accurate lateralization in patients with suspected bitemporal epilepsy.

Young Disabled Adults Facing Developmental Tasks and Life Choices – In Search of Daily Life Quality

Emerging adulthood, in numerous individual biographies, also in the case of disabled people, is the time of permanent need for self-actualisation and time of verifying one’s subjective vision of “being an adult,” i.e. being responsible for one’s own decisions, pursuing professional and economic independence. Due to developmental acceleration, sociological shift in terms of undertaken roles and realized developmental tasks as well as their moratoriumlinked delays, it is also the time conducive to educational activity. This psychological time of a young person, its course and specificity depend, to a large extent, on numerous (micro-, mezo- and macro-) conditions of family life and social life in today’s world which is more competitive and less predictable than it used to be for generation of the late 1990s. All of these factors contribute to the fact that maturing to adulthood seems to be a state which is harder to achieve nowadays. It is displayed in the form of delaying the moment of taking up a job or other important decisions in family and relationship contexts.The study aims to present the selected aspects of daily life of disabled young adults, described in the context of developmental tasks of this period and considering the perspective of investment in relationships, development of one’s own resources, pursuing education and entering the job market which are all, from a temporal perspective, a chance of complementing one’s own identity.

PHOTODYNAMIC THERAPY FOR SYMPTOMATIC SUBFOVEAL RETINAL PIGMENT EPITHELIAL DETACHMENT IN CENTRAL SEROUS CHORIORETINOPATHY: Outcomes and Prognostic Factors.

To report the clinical outcomes of reduced-fluence photodynamic therapy (PDT) for symptomatic subfoveal retinal pigment epithelial detachment (RPED) in central serous chorioretinopathy and identify prognostic factors affecting treatment outcome. This retrospective interventional study included 35 eyes of 35 patients with serous subfoveal RPED with choroidal hyperpermeability. Cases with evidence of age-related macular degeneration were excluded from the study. Reduced-fluence PDT was applied to each patient. Best-corrected visual acuity, anatomical resolution of RPED, subjective symptom improvement, and complications were analyzed. One month after reduced-fluence PDT, 28 eyes (80.0%) manifested complete resolution of subfoveal RPED. Among the patients whose eyes manifested complete resolution, 19 (67.9%) reported subjective vision improvement. This subjective improvement was significantly associated with the presence of dysmorphopsia at baseline. Logarithm of the minimal angle of resolution visual acuity improved from 0.15 (Snellen equivalent of 20/28) to 0.09 (20/25) between baseline and 3 months after PDT (P = 0.008). Older age and increased RPED height were independent risk factors of poor resolution of RPED after PDT. The mean follow-up period after treatment was 10.4 ± 13.6 months; recurrence of RPED did not occur in any case. Subfoveal RPED in central serous chorioretinopathy responded well to reduced-fluence PDT, especially in younger patients with less RPED. Dysmorphopsia, rather than decreased visual acuity, is a main symptomatic presentation in subfoveal RPED.

Social Quality Measurement and Perceived Social Quality

This study investigates the difference between the maps of social quality and perceived social quality. Using survey data collected from Peshawar, a prominent city in Pakistan, we compare the general and the perceived maps of social quality drawn from survey respondents based on their stands of income, education, age, and gender. With this comparison, the study conducts the regression analysis about the data to reveal the relations between these factors and draw some policy implications. The analysis contrasting objective and subjective visions of the social quality map may support a constructionist view on social quality and, more essentially, bring our view into the diversity of the perceived maps of social quality in reference to the interests of different social groups in society.

Endovascular stenting for idiopathic intracranial hypertension with venous sinus stenosis.

ObjectivesIdiopathic intracranial hypertension (IIH) is characterized by elevated intracranial pressure of unknown etiology and venous sinus stenting may be an optional treatment. We aimed to evaluate the effects of venous sinus stenting on visual function, intracranial pressure, and trans‐stenotic pressure gradient of the patients with IIH and to determine effects of baseline BMI or weight changes on subjective vision outcome and intracranial pressure.MethodsFrom July 2009 to Aug 2016, 88 eligible patients with IIH and venous sinus stenosis who underwent stenting were retrospectively studied.ResultsIn this study, 67 women and 21 men were included with an average age of 39.01 (18–60) years. The average BMI was 26.75 kg/m2. Here, 66 (75.9%) patients had papilledema, 39 had impaired vision before stenting; 57 patients were followed‐up, 48 (84.2%) showed significant subjective improvement or recovery in visual acuity, 4 (7.0%) patients reported no significant change in visual functions, and 5 (8.8%) suffered permanent vision loss. The cerebrospinal fluid opening pressure and trans‐stenotic pressure gradient were significantly decreased postoperatively. Baseline BMI was associated with pre‐and postoperative trans‐stenotic pressure gradients, as well as changes in cerebrospinal fluid opening pressure. However, baseline BMI and body weight changes during follow‐up were not necessarily associated with subjective visual outcomes after stenting. Stenting efficacy was limited in patients with severe preoperative optic symptoms.ConclusionsVenous sinus stenting represented an effective treatment for resolving visual dysfunction and intracranial pressure associated with venous sinus stenosis. BMI seemed to be associated with intracranial pressure but not subjective visual outcomes after stenting.

The Relationship between Visual Acuity, Subjective Vision, and Willingness to Purchase Simultaneous-image Contact Lenses.

This study reports that subjective vision ratings are better indicators of willingness to purchase simultaneous-image contact lenses than visual acuities and are more valuable in evaluating contact lens performance. The purpose of this study was to investigate the relationship between visual acuities, subjective vision ratings, and willingness to purchase simultaneous-image contact lenses in presbyopes. A retrospective analysis of visual acuities, subjective vision ratings, and willingness to purchase from final visits of two masked, crossover clinical trials of nine prototype and four commercially available simultaneous-image contact lenses in 141 presbyopes was performed. Pearson correlation and area under the receiver operating characteristic curve determined correlations between variables. Most subjective vision ratings were weakly correlated (r < 0.3) with visual acuity at all distances and illumination. Moderate correlations (r, 95% confidence intervals) were found between overall vision satisfaction ratings with visual acuity at 40 (-0.34, -0.28 to -0.40) and 50 cm (-0.33, -0.27 to -0.39), near-vision ratings (daytime) with visual acuity at 40 (-0.48, -0.43 to -0.53) and 50 cm (-0.46; -0.41 to -0.51), and intermediate-vision ratings (daytime) with visual acuity at 40 (-0.39, -0.33 to -0.45) and 50 cm (-0.41, -0.35 to -0.46). Highest discrimination for willingness to purchase was with overall vision satisfaction (area under curve, 0.93) and vision stability (daytime; area under curve, 0.77). Ratings from 4 to 9 for vision satisfaction showed a linear increase in willingness to purchase: a 1-unit increase in vision satisfaction increased willingness to purchase by 20%. Ratings lower than 4 had 0% willingness to purchase. Other subjective ratings showed similar relationships, albeit only 10 to 15% increase in willingness to purchase per unit increase for ratings higher than 4. Subjective vision ratings are a better indicator of simultaneous-image contact lens performance than visual acuity. Overall vision satisfaction and vision stability are key predictors of willingness to purchase. Subjective vision ratings should be used to evaluate performance rather than visual acuity alone.

Image Shadow Removal Using End-To-End Deep Convolutional Neural Networks

Image degradation caused by shadows is likely to cause technological issues in image segmentation and target recognition. In view of the existing shadow removal methods, there are problems such as small and trivial shadow processing, the scarcity of end-to-end automatic methods, the neglecting of light, and high-level semantic information such as materials. An end-to-end deep convolutional neural network is proposed to further improve the image shadow removal effect. The network mainly consists of two network models, an encoder–decoder network and a small refinement network. The former predicts the alpha shadow scale factor, and the latter refines to obtain sharper edge information. In addition, a new image database (remove shadow database, RSDB) is constructed; and qualitative and quantitative evaluations are made on databases such as UIUC, UCF and newly-created databases (RSDB) with various real images. Using the peak signal-to-noise ratio (PSNR) and the structural similarity (SSIM) for quantitative analysis, the algorithm has a big improvement on the PSNR and the SSIM as opposed to other methods. In terms of qualitative comparisons, the network shadow has a clearer and shadow-free image that is consistent with the original image color and texture, and the detail processing effect is much better. The experimental results show that the proposed algorithm is superior to other algorithms, and it is more robust in subjective vision and objective quantization.

Estimation of atmospheric light based on gaussian distribution

Existing defogging algorithms use a small number of sample points to estimate the atmospheric light, which leads to poor defogging effect. To solve this problem, a novel Gaussian distribution based algorithm for atmospheric light estimation is proposed. The algorithm has the following features: it uses a brightness threshold to select the candidate points to increase the number of initial samples; it uses clustering algorithms to merge the point clusters for increasing the samples included in the candidate point cluster; it uses a proportional threshold to filter out unreasonable point clusters; it regards each candidate point cluster as a single light source and calculates their influence on surrounding pixels with a Gaussian-distribution-based model; and it uses an atmospheric light map (instead of a constant value) to restore the image. The experimental results suggest that the defogging results produced by the proposed algorithm look more natural than the original algorithm under subjective vision and the objective image quality evaluation indicators are also excellent.

Psychophysical Evaluation of Visual Functions of Ex-Alcoholic Subjects After Prolonged Abstinence.

Chronic alcohol abuse can lead to a brain damages, and the health status of alcoholics even after a long-term alcohol abstinence is a public health concern. The present study investigated the color vision and spatial luminance contrast sensitivity of a group of 17 ex-alcoholics (46.3 ± 6.7 years old) in long-term alcohol abstinence after having been previously under alcohol dependence for many years. We also investigated the association of impaired psychophysical performance in different tests we applied. The mean time of alcohol consumption was 16.9 ± 5.1 years and the mean abstinence period was 12.4 ± 8.5 years. Achromatic vision of all subjects was evaluated using spatial luminance contrast sensitivity function (CSF) test and color vision was evaluated using Mollon–Reffin color discrimination test (MR) and the Farnsworth–Munsell 100 hue arrangement test (FM100). Relative to controls, the spatial luminance contrast sensitivity was lower in 10/17 of the ex-alcoholic subjects. In the color vision tests, 11/16 ex-alcoholic subjects had impaired results compared to controls in the FM100 test and 13/14 subjects had color vision deficits measured in the MR test. Fourteen subjects performed all visual tests, three subjects had impaired results for all tests, seven subjects had impaired results in two tests, three subjects had visual deficit in one test, and one had normal results for all tests. The results showed the existence of functional deficits in achromatic and chromatic vision of subjects with history of chronic alcoholism after long abstinence. Most subjects had altered result in more than one test, especially in the color vision tests. The present investigation suggests that the damage in visual functions produced by abusive alcohol consumption is not reversed after long term alcohol abstinence.

Patient-reported vision-related quality of life after bilateral wavefront-guided laser in situ keratomileusis

To evaluate functional vision and quality-of-life outcomes after bilateral wavefront-guided laser insitu keratomileusis (LASIK). Byers Eye Institute, Stanford University School of Medicine, Palo Alto, California, USA. Prospective case series. Visual acuity, refractive error, and aberrometric measurements were obtained preoperatively and 1, 6, and 12months after bilateral wavefront-guided LASIK. The Refractive Status and Vision Profile questionnaire scores were completed at each timepoint and compared with baseline scores. The study comprised 84 eyes of 42 patients (aged 24 to 47years). At 1year, 76 eyes (90.5%) had an uncorrected distance visual acuity of 20/20 or better and 88.1% of patients were satisfied with their vision without correction. Total refractive status and vision profile scores improved significantly from a mean of 30.9 points at baseline to 20.7 points 1year postoperatively (P<.001). The visual function, perceptions, and problems with corrective lenses subscales statistically significantly improved from preoperatively to postoperatively (all P<.001). In contrast, the driving (P=.286) and visual symptoms subscales (P=.199) did not show significant changes from baseline to 1year. Wavefront-guided LASIK not only afforded clinically measurable improvements in vision but also significant improvements in subjective functional vision and vision-related quality of life 1year after surgery.

Enhancement of hyperspectral remote sensing images based on improved fuzzy contrast in nonsubsampled shearlet transform domain

In order to deal with the pseudo-Gibbs phenomenon in the process of hyperspectral remote sensing image enhancement, a novel image enhancement method based on nonsubsampled shearlet transform (NSST) is proposed in this paper. The main motivation of this study is to adjust the coefficient of remote sensing image enhancement as a pattern recognition task. Firstly, the input image is decomposed into a low-frequency component and some high-frequency components by NSST decomposition; Secondly, the guided filter is applied to process the low-frequency component to improve the contrast, and the improved fuzzy contrast is used to suppress the noise of the high-frequency components; Thirdly, the processed coefficients of low-frequency and high-frequency are reconstructed by inverse nonsubsampled shearlet transform (INSST), and the final enhanced image is obtained. The experimental results demonstrate that the proposed approach has obvious advantages in terms of objective data and subjective vision.

Sex Determination of Three-Dimensional Skull Based on Improved Backpropagation Neural Network.

Sex determination from skeletons is a significant step in the analysis of forensic anthropology. Previous skeletal sex assessments were analyzed by anthropologists' subjective vision and sexually dimorphic features. In this paper, we proposed an improved backpropagation neural network (BPNN) to determine gender from skull. It adds the momentum term to improve the convergence speed and avoids falling into local minimum. The regularization operator is used to ensure the stability of the algorithm, and the Adaboost integration algorithm is used to improve the generalization ability of the model. 267 skulls were used in the experiment, of which 153 were females and 114 were males. Six characteristics of the skull measured by computer-aided measurement are used as the network inputs. There are two structures of BPNN for experiment, namely, [6; 6; 2] and [6; 12; 2], of which the [6; 12; 2] model has better average accuracy. While η = 0.5 and α = 0.9, the classification accuracy is the best. The accuracy rate of the training stage is 97.232%, and the mean squared error (MSE) is 0.01; the accuracy rate of the testing stage is 96.764%, and the MSE is 1.016. Compared with traditional methods, it has stronger learning ability, faster convergence speed, and higher classification accuracy.

Results of Vitreous Floaters Treatment Using a Yag-Laser Device with a Coaxial Light Splitter

Purpose: to evaluate the efficiency of vitreous floaters removal using the Nd: YAG-laser DIXION LPULSA SYL-9000 with a coaxial light splitter. Patients and Methods. The study involved 24 patients (24 eyes) with Weiss ring-type floating vitreous opacities. All patients underwent laser vitreolysis on a Nd: YAG-laser DIXION LPULSA SYL-9000 with a coaxial light splitter. Laser procedures were performed at OPTIMED Laser Recovery Center. The age of the patients was from 47 to 81 years (average 58.3 ± 8.9 years). Among the patients 15 (62.5 %) were women and 9 (37.5 %) — men. Before procedure, a complete ophthalmological examination including registration of best corrected visual acuity (BCVA), autorefractometry, pneumotonometry, biomicroscopy, fundus examination, ultrasonic biometry, ultrasound B-scan was performed. Statistical processing was performed using Statistica v.10.0.0 (StatSoft®, Inc.) and Excel (Microsoft Office Professional 2016) software. The patients were observed for three months before the procedure. Follow-up examination was performed one day after the procedure. Results. After laser vitreolysis procedure all patients had a subjective vision quality improvement. In 18 (75 %) patients, floating “flies” completely disappeared. The remaining patients noted the disappearance of a large floating spot. Conclusion. The laser vitreolysis on the Nd: YAG-laser with a coaxial light splitter allows to improve the quality and visual acuity in patients with vitreous floater. The obtained results demonstrated that Nd: YAG-laser DIXION LPULSA SYL-9000 is effective and could be recommended for treatment of symptomatic vitreous floaters.

Enactive Phenomenological Approach to the Trier Social Stress Test: A Mixed Methods Point of View.

The single Trier Social Stress Test (TSST) and the TSST for groups (TSST-G) are the most used protocols to experimentally induce psychosocial stress. These tests are based on uncontrollability and social-evaluative threat, inducing psychological and physiological consequences (e.g., anxiety, emotional states, salivary cortisol increases). Many quantitative experimental studies have investigated these stress inducers and these consequences. But, as far as we know, this study is the first to provide a qualitative analysis to access the participants' voices so as to understand the dynamics of their experience throughout the TSST and the TSST-G. This paper outlines a mixed methods approach to the TSST. This approach can help to maximize the information that can be gained from the TSST, which researchers often use without looking more closely at what is qualitatively happening psychologically for participants during the stressor itself. In this way, this protocol is an example of mixed methods, showing the added value of using the enactive phenomenological approach to analyze experimental protocols more deeply. This kind of mixed methods is helpful to access the experience, to understand the actor's point of view, and to analyze in-depth the dynamics of cognitive processes like intentions, perceptions, enacted knowledge, and emotion. The discussion section shows the different uses of a mixed methods protocol, exploiting the enactive phenomenological approach to analyze a protocol or to give a cross vision of the same research subject. This section deals with different existing applications, pointing out some critical steps in this mixed methods approach.

The Topographical Effect of Optical Zone Diameter in Orthokeratology Contact Lenses in High Myopes.

Purpose To evaluate the effect of the optical zone diameter (OZ) in orthokeratology contact lenses regarding the topographical profile in patients with high myopia (−4.00 D to −7.00 D) and to study its effect over the visual quality. Materials and Methods Twelve patients (18 eyes) were fitted with overnight orthokeratology (OrthoK) with a randomized 6 mm or 5 mm OZ lens worn for 2 weeks, followed by a 2-week washout period, between both designs. Keratometry (K) readings, optical zone treatment diameter (OZT), peripheral ring width (PRW), higher-order aberrations (HOA), high (HC) and low contrast (LC) visual acuity, and subjective vision and comfort were measured at baseline and after 2 weeks of OrthoK lens wear of each contact lens. Results No significant differences were found between any measurements for the same subject at both baselines (p value > 0.05). There was no difference between OZ lens designs found in refraction, subjective vision or comfort, and HC and LC visual acuity. Contrast sensitivity was decreased in the 5 mm OZ lens design compared with 6 mm OZ design (p-value < 0.05). 5 mm OZ design provoked a greater flattening, more powerful midperipheral ring and 4th-order corneal and total spherical aberration than the 6 mm OZ design, being statistically significant after 7 days, for corneal aberration, and 15 days, for corneal and total, of wearing the lens (p-value < 0.05). The OZT obtained were 2.8 ± 0.2 mm and 3.1 ± 0.1 mm for 5 mm and 6 mm OZ design, respectively (p-value < 0.05). Regarding PRW, the 5 mm OZ design had a wider ring width in both the nasal and temporal zones (p-value < 0.05). Conclusions A smaller diameter optical zone (5 mm) in orthokeratology lenses produces a smaller treatment area and a larger and more powerful midperipheral ring, increasing the 4th-order spherical aberration that affects only the contrast sensitivity but without differences in visual acuity and subjective vision compared with a larger OZ diameter (6 mm).

KAMRA Inlay Implantation for Presbyopia Compensation: A Retrospective Evaluation of Patient Satisfaction and Subjective Vision 12-Month Postoperative.

PURPOSE:The aim of the study is to evaluate patients' satisfaction and subjective vision 12 months after monocular KAMRA corneal inlay implantation for the surgical compensation of presbyopia.SUBJECTS AND METHODS:Medical records of patients who underwent corneal inlay implantation in the nondominant eye between 2013 and 2014 were retrospectively reviewed. Data were collected from several centers in Lebanon. Patients with hyperopia or myopia with presbyopia between 45 and 70 years not suffering from any other ocular pathology were eligible for inclusion. Twelve-month postoperative satisfaction score was evaluated in all patients as well as the subjective vision score for near, intermediate, and distant tasks.RESULTS:This study included 73 patients. Almost 95% (69/73) of patients were satisfied or very satisfied with their vision and 93% (68/73) never or almost never used reading glasses while performing daily tasks. Subjective vision scores were found to be higher for distant and intermediate tasks performed during the day than for those performed during the night (P < 0.001). The average subjective vision score for reading a book or a newspaper in dim light was the lowest among all average subjective vision scores. No difference in satisfaction was found between patients with myopia or hyperopia or between males and females.CONCLUSION:The implant of a small-aperture corneal inlay resulted in a substantial improvement in patients' distant, intermediate, and near subjective vision, better in normal light than in dim light, and most patients became spectacles independent.

Multi-Regularization-Constrained Blur Kernel Estimation Method for Blind Motion Deblurring

Blur kernel (BK) estimation is the crucial technique to guarantee the success of blind image deblurring. In this paper, we propose a multi-regularization-constrained method to estimate an accurate BK from a single motion-blurred image. First, in order to generate sharp and reliable intermediate latent results, we propose a model which combines the spatial scale, ${L} _{0}$ norm, and the dark channel prior. Second, in order to preserve the continuity and the sparsity, and to remove the flaw in the BK, a dual-constrained regularization model, which combines the ${L} _{0}$ -regularized intensity prior and the ${L} _{2}$ -regularized gradient prior, is proposed for accurate BK estimation. The proposed model can not only preserve the continuity and the sparsity of the BK very well but also can remove the flaw thoroughly. Finally, we propose an efficient optimization strategy which can solve the proposed model efficiently. Extensive experiments compared with the state-of-the-art methods demonstrate that our method estimates more accurate BKs and obtains higher quality deblurring images in terms of both subjective vision and quantitative metrics.

Afro-Brazilian Women and Gendered Performance in the teatro de revista in the Long 1920s

This article focuses on two Afro-Brazilian women, Rosa Negra and Déo Costa, who performed in the first Brazilian popular theatrical companies that consciously identified as Afro-descendant, the Companhia Negra de Revistas (1926–27) and the Ba-ta-clan Preta (1926–27). It draws on press coverage and the reception of performances by these women, situating them within the wider context of representations of Afro-Brazilian female subjectivity on the popular stage in Brazil since the turn of the century and in relation to transnational Afro-descendant performers such as Josephine Baker and Florence Mills, who enjoyed considerable success in the USA and abroad. In addition to press sources, this article analyses a small number of extant revue scripts, including song lyrics and stage directions, to illuminate the engagement of these theatrical companies, and their black female performers, with transnational performance trends and modernist aesthetics in the long 1920s. Furthermore, it seeks to illustrate the assertive cosmopolitanism strategically adopted by these women. It addresses the following questions: How do we interpret the fact that these women felt obliged to position themselves in relation to a global or imported blackness? And how did they interpret and internalize the politics of their situation and self-presentation? Furthermore, what can these Brazilian examples contribute to discussions of the global political consequences of a transnationalized black performance culture in the inter-war period? This article illustrates how, in addition to participating in and contributing to the performative celebration of modern, racialized womanhood, Rosa Negra and Déo Costa also put this new vision of black female subjectivity into practice in their everyday lives, defiantly challenging social, gender, and class hierarchies, debating the issue of intellectual property, in Costa’s case, and race relations, in the case of Rosa Negra. It argues that they demonstrate an astute awareness of intersectionality avant la lettre.
