Outros espaços nas artes visuais
Authors: Fabbrini Ricardo

O artigo caracteriza, inicialmente, a concepção de temporalidade que vigorou no imaginário das vanguardas artística dos anos 1910 aos anos 1930: a ideia de um tempo linear, sucessivo, cumulativo, homogêneo e “vazio”, porque para ser conquistado. Foi esta concepção de tempo prospectivo, teleológico, no qual o télos é a Utopia, que orientou as vanguardas construtivas até a Segunda Guerra Mundial. Depois do Holocausto (ou das bombas de Hiroxima e Nagasaki), as ideias de progresso, ou de aperfeiçoamento, próprias dessa concepção prospectiva do tempo, ruíram. O futuro deixou de ser considerado o reino da esperança, da projeção do desejo, para tornar-se sombrio ou ameaçador. Desde então, vigora no imaginário artístico-cultural a noção de distopia, ou utopia negativa, entendida como a figuração de uma sociedade opressiva projetada no futuro próximo ou distante, à qual se chegará se não forem alterados os rumos da história. É o que verificamos nas obras visuais do alemão Harun Farocki, do chinês Ai Weiwei e do espanhol Antoni Muntadas, realizadas nas três últimas décadas, nas quais a distopia é apresentada como sociedade de controle. Por fim, acentuamos que diversos críticos de arte vêm mobilizando desde os anos 1990 a noção de heterotopia de Michel Foucault para caracterizar o poder de negatividade de certa arte contemporânea. Recordamos que as heterotopias são, para o autor, “contraposicionamentos em lugares reais”, “lugares efetivos”; ou seja, “lugares” que, em aparente paradoxo, “estão fora de todos os lugares, embora sejam efetivamente localizáveis”, como ocorreria, a nosso ver, nas instalações de Rirkrit Tiravanija (ou, mais remotamente, em Lygia Clark, e Hélio Oiticica).

Tell me Still, Angola the False Thing that is Dystopia
Authors: Luis Solange 
Published: May 2021

José Luis Mendonça’s book Angola, me diz ainda brings together poems from the 1980s to 2016, unveiling a constellation of images that express the unfulfilled utopian Angolan dream. Although his poems gravitate around his personal experiences, they reflect a collective past. They can be understood as what Walter Benjamin referred to as monads, as historical objects (c.f. Benjamin) based on the poet’s own experiences, full of meaning, emotions, feelings, and dreams. Through these monadic poems, his poetry establishes a dialogue with the past. The poet´s dystopic present is that of an Angola distanced from the dream manifested in the insubmissive poetry of Agostinho Neto and of the Message Generation, which incited decolonization through a liberation struggle and projected a utopian new nation. Mendonça revisits Neto’s Message Generation and its appeal to discover Angola: unveiling a nation with a broken dream and a dystopic present, denouncing a future that is still to come. The poet’s monads do not dwell on dystopia but wrestle conformism, fanning the spark of hope (c.f. Benjamin). They expose the false thing (c.f. Adorno), inciting the longing for something true: reminding the reader that transformation is inevitable.
On Market Concentration and Disclosure
Authors: Cheynel Edwige , Ziv Amir 
Published: May 2021

ABSTRACT
Verrecchia (1983, 1990) introduced the proprietary cost hypothesis in which exogenous disclosure costs are a reduced-form interpretation of lost competitive advantage in product markets. We develop a micro-foundation for this disclosure cost in a Cournot game and explicitly derive the cost as a function of market structure. When the market is sufficiently competitive, this model has a reduced-form representation similar to a standard voluntary disclosure game with a partial disclosure equilibrium. Proprietary costs are increasing in the number of competitors, the degree of product substitution, overall uncertainty, and production costs. The analysis also offers new empirical predictions on the interaction between disclosure choice, managerial horizon, and entry.

Abstract
Pollen characteristics are very important for Iris interspecific hybridisation. In this study, the pollen viability and male meiosis were studied in yellow-flowered Iris dichotoma (Y2), I. domestica (S3) and their hybrids F1, F2 and BC1 (BC1-Y and BC1-S). The BC1-Y hybrids showed higher pollen viability than that of F1, F2 and BC1-S hybrids, which were between I. dichotoma (26.1%) and I. domestica (35.1%). Two sterile hybrids, F2-1 and BC1-S-1, exhibited more meiotic abnormalities (57.3% and 58.7%) than other individuals. During the first meiotic division, a diffuse diplotene stage was observed for the first time in the genus Iris. The meiotic abnormalities included non-congressed chromosomes, chromosome bridges, lagging chromosomes, unequal division, abnormally oriented spindle fibres, nonsynchronous division and polyad, and resulted in reduced pollen fertility. The relatively high frequency of 2n pollen grains was found in hybrids of BC1-Y-2, BC1-Y-1, BC1-S-2, BC1-S-3 and BC1-S-4. Our research provides a new resource for meiotic behaviour and pollen fertility of the genus Iris.
Determinantes prosódicos em mudança sintática
Authors: Kato Mary Aizawa , Duarte Maria Eugenia Lammoglia 
Published: May 2021

O presente trabalho relata uma trajetória de estudos das presentes autoras sobre a mudança no Português Brasileiro (PB), no que diz respeito ao Parâmetro do Sujeito Nulo. Na fase em que esse Parâmetro incluía a inversão livre como uma de suas propriedades, verificou-se que a inversão românica, ou inversão do predicado no PB, era uma regra prosódica, aparentemente independente da perda parcial do sujeito nulo. Verificou-se que, embora a inversão tenha passado a ser restrita no PB, um elemento dêitico ou locativo pré-verbal favorecia a inversão. Além disso, assumindo o sujeito nulo referencial como resultante de elipse do pronome, verificou-se que o apagamento era favorecido quando o verbo era precedido de algum elemento leve. Propomos aqui, então, que a ocorrência parcial do sujeito nulo no PB pode ter a ver com uma demanda prosódica parcial, de rejeição a um padrão prosódico sentencial V1, demanda essa não existente no século XIX. Nossa proposta é que, na interface com PF, as línguas têm filtros em relação ao seu ritmo. Para dar conta da preferência de certas formas nesse estágio da mudança, em curso no PB, uma condição do tipo “Evite V1” está sendo proposta.
Rare Presentation of Concomitant Alopecia Areata and Vitiligo in a Teenager
Authors: Jimenez Antonio Roberto , Hoyer Paige , Ross Lindy 
Published: May 2021

Introduction: Alopecia areata (AA) and vitiligo are two chronic, autoimmune skin diseases. While these two conditions are common, their co-existence is rare.
Case Presentation: A 13-year-old Caucasian female presented to the dermatology clinic with a 1-2-month history of hair loss on her occipital scalp. The patient was diagnosed with AA and prescribed topical mometasone 1% lotion twice daily and pulse-dose prednisolone solution 12 mL 1 day per month for 3 months. At her 3-month follow-up, the patient reported new-onset hair depigmentation. On physical examination, the patient’s occipital scalp and right eyelash demonstrated a depigmented patch of hair, concerning for vitiligo. The patient was diagnosed with concomitant disease and topical tofacitinib was added to her treatment regimen.
Discussion/Conclusion: The colocalization of AA and vitiligo is rare, and the presentation suggests an underlying pathogenic link between the two skin diseases. While the definitive immunologic pathway remains unknown, researchers have narrowed down inflammatory markers involved in the development of both conditions, including CD8+ cytotoxic T-cells, interferon gamma (IFN-ɣ), and IFN-ɣ-induced chemokines. We present a 13-year-old female patient who presented to the clinic with scalp alopecia and later developed overlying scalp and eyelash vitiligo. The rare nature of the patient’s presentation makes concomitant disease a therapeutic challenge and can impose significant psychological distress to a pediatric patient.
Utility of the spinal instability neoplastic score to identify patients with Gorham-Stout disease requiring spine surgery
Authors: Gui Chloe , Rocos Brett , Lohkamp Laura-Nanna , Cheung Angela , Bleakney Robert , Massicotte Eric 
Published: May 2021

Background:
Gorham-Stout disease (GSD) is a rare syndrome presenting with progressive osteolysis which in the spine can lead to cord injury, instability, and deformity. Here, the early spine surgery may prevent catastrophic outcomes.

Case Description:
A 25-year-old male with GSD involving the T2 to T6 levels presented with acute traumatic kyphoscoliosis at T3 and T4 and left lower extremity paraparesis. The CT scan 4 weeks before this showed progressing osteolysis versus the CT 5 years ago. Unfortunately, the patient underwent delayed treatment resulting in permanent neurological sequelae. Surgery included a laminectomy and vertebrectomy of T3/T4 with instrumented fusion from T1-10. The use of the spinal instability neoplastic score (SINS) is a useful tool to prompt early referral to spine surgeons.

Conclusion:
We recommend using the SINS score in GSD patients who develop spinal lesions to prompt early referral for consideration of surgery.

Published: May 2021

Lemongrass traditionally can be used as a mixture of water bath for rheumatic patients, antiseptic medicine, headache reducer, unbend the leech bite and overcome insect bite, but, the bioactivity potential of citronella lemongrass still remains unknown. The content of citronella lemongrass is known to have secondary metabolites such as flavanoid, phenolic, and terpenoid. The aim of this study is to determine the LC50 value (Lethality Concentration 50) in the root, stem, and leaves part of citronella lemongrass. Citronella lemongrass is extracted with maceration method using 96% ethanol solvent. Rendement value of leaf extract is greater than the value of stem and root extract, which is equal to 8.69% for stem extract, 3.73% for root extract and 9.70% for leaves extract. A toxicity test was performed by using the BSLT method, shrimp larvae were inserted into the test solution with each different solution concentration. LC50 values were obtained based on the calculation of percent mortality of shrimp larvae by using probit analysis. LC50 ethanol extract 96% of citronella lemongrass leaf is 67.841 μg/ml, citronella lemongrass stem is 31.604 μg/ml and citronella lemongrass root is 10.489 μg/ml. LC50 value shows that ethanol extract 96% of root, stem, and leaf of citronella lemongrass have no bioactivity potential due to the value of LC50 is greater than 1000 μg/ml.

The purpose of the article is to study the history of creation and the ideological content of the mosaic by Mykola Andriyovych Storozhenko (1928–2015) "Lviv Stavropegic Brotherhood of the 16th – 18th centuries." in the interiors of N.N. Bogolyubov ITF of the National Academy of Sciences of Ukraine in Feofaniya (1969) in the context of the heritage of Ukrainian and world monumental art. Methodology.The study uses historical and cultural, comparative, iconographic and iconological methods. We rely on the hermeneutics of Hans-Georg Gadamer and the theory of "big time" by M.M. Bakhtin, which allows us to consider the mosaics of M.A. Storozhenko in the context of the heritage of world art. Main results. In the mosaic "Lexicon”, the greatness of the word is affirmed by means of monumental art. Storozhenko restores its sacred meaning, forgotten in the days of atheism. The master showed the importance of the printed word for the formation of Ukrainian culture. The ideological content of the monumental composition “Stauropegia. Lexicon": the educational value of words and art. Combining the interiors of the printing house and art workshop with the architectural space of the city, the master creates the image of Lviv as a cultural and educational center of Orthodoxy in Western Ukraine. The use of comparative analysis showed that M. Storozhenko synthesizes the artistic heritage of the ancient world (Tripoli, Egypt), Kievan Rus (monumental art and miniature), Renaissance, Rococo, Cubism, abstractionism and others. Polystylism, characteristic of art of the XX–XXI centures, became the basis for the formation of the individual artistic style of one of the leading artists of our time. Scientific novelty. The cultural-historical and artistic meaning of the monumental mosaic of M.A. Storozhenko has been studied in connection with the problems of national self-identification and polystylism of art of the twentieth century. Practical significance. The results of the study are necessary for the creation of a modern history of monumental and decorative art of Ukraine.
