Background:

A synchronized involuntary movement of the tongue to the same side as voluntary movements of the eyes, termed the oculoglossal phenomenon, has been observed. A description of the hypothesized pathway of this phenomenon could guide the development of a rapid clinical evaluation of the long segment of the brainstem and help facilitate further studies to establish a new reflex, if possible. The aim of this study is to describe and propose the simple concept of this pathway/phenomenon, the oculoglossal phenomenon.

Methods:

This is an observational study. Of a newly observe brainstem phenomenon evaluated on a subject at the National Neuroscience Institute in king Fahad Medical City (KFMC), Riyadh, Saudi Arabia. After being observed incidentally in a single patient, 60 participants were tested between January and March 2020 to confirm the presence of the phenomenon. Each subject was instructed to protrude the tongue and then move their eyes horizontally to the side. If the tongue simultaneously and involuntarily moved to the same side as the eyes, the test was deemed confirmatory. A literature review was performed, and possible anatomical pathway was proposed.

Results:

The oculoglossal reflex was present in most (50/60, 83.3%) of the subjects. Our proposed pathway begins at the frontal cortex, followed by a projection to the paramedian pontine reticular formation, then to the contralateral medial longitudinal fasciculus and bilaterally to the hypoglossal nuclei.

Conclusion:

An accurate description of this phenomenon could lead to additional studies and possibly establishing it as a legitimate reflex, thus conceivably adding a new tool in the neurological examination to evaluate the brainstem’s integrity.

Horseshoe-shaped retinal tear leads to rhegmatogenous retinal detachment (RRD) in 61-83% of cases. Vitreoretinal traсtion is the main factor in the development of horseshoe tears and RRD. In this aspect, YAG-laser retinotomy is promising, which makes it possible to eliminate the traction component by excision area of the horseshoe tear with vitreoretinal adhesion (VRA). Purpose. To analyze the results of YAG-laser retinotomy in the treatment of patients with complicated horseshoe tears and rhegmatogenous retinal detachment. Material and methods. The study included 97 patients (100 eyes). Of these, 54 patients (57 eyes) with complicated horseshoe retinal tears and 43 patients (43 eyes) with local RRD. Patients with complicated horseshoe tears underwent YAG-laser retinotomy at the base of the horseshoe tear. Patients with local RRD underwent a combined laser-surgical technology, which included YAG-laser retinotomy of the horseshoe tear area with vitreoretinal adhesion, pneumatic retinopexy and barrier laser photocoagulation. Results. In the group of patients with complicated horseshoe tears, complete retinal attachment was achieved in 15 eyes (58%), partial retinal attachment - in 7 eyes (27%). In the group of patients with local RRD complete retinal attachment was achieved in 40 patients (93%). There was a stable anatomical result and no changes in functional parameters. Conclusion. YAG-laser retinotomy eliminates vitreoretinal traction in the area of horseshoe tear and prevents the development of rhegmatogenous retinal detachment. Application of YAG-laser retinotomy as the first step of a microinvasive combined laser-surgical technology for the treatment of RRD makes it possible to obtain a high anatomical result, reduce the risk of retinal redetachment, and also preserve the initially high visual functions of patients.

Purpose. To evaluate the efficiency of Aflibercept in patients with various vas-cular and neovascular diseases of the retina. Material and methods. 43 patients (55 eyes) with various ophthalmic patholo-gies were treated: wet form of age-related macular degeneration of the retina (AMD), myopic CNV, diabetic macular edema (DME) and macular edema due to occlusion of the retinal veins. Among them, 17 (39.5%) men and 26 (60.5%) women aged 38 to 84 years (62±1.9 years). All patients underwent a compre-hensive ophthalmological examination. A total of 158 intravitreal injections (IVI) of Aflibercept were performed. The observation period was 6 months. The efficiency of treatment was assessed according to the data of visual acuity, OCT, as well as subjective feelings and changes in the area of central scotoma. Results. Visual acuity among all patients after three loading injections increased by an average of 2.8 lines. Subjective improvement in visual functions was noted in 38 (89%) patients. The greatest increase in visual functions was observed in the exudative form of wet AMD, which manifests itself mainly in the form of detachment and / or edema of the neuroepithelium. The smallest in-crease in visual acuity was observed in patients with exudative-hemorrhagic form of wet AMD with detachment of the pigmented epithelium and neuroepi-thelium, as well as in myopic CNV. Over the next three months after the course of loading injections, visual acuity increased by an average of 5-7%. The thick-ness of the retina in the fovea decreased by an average of 156.8 ± 52 µm (from 45 to 290 µm), while the greatest decrease in the thickness was observed in pa-tients with DMO and exudative form of wet AMD, manifested as detachment of neuro- and pigmented epithelium, and the least expressed was in myopic CNV. Conclusion. The use of IVV Aflibercept is effective in various vascular and ne-ovascular diseases of the retina. The highest functional result is observed in pa-tients with an exudative form of wet AMD, manifested by detachment and / or edema of the neuroepithelium.

Purpose. To study the effectiveness of micropulse laser cyclophotocoagulation (CPC) use in the treatment of hemophthalmos with ophthalmic hypertension. Materials and methods. Examination and treatment of 11 patients (11 eyes) with fresh hemophthalmos with secondary uncompensated ophthalmic hypertension were carried out. Antiglaucoma surgery was considered inappropriate due to the high threat of serious hemorrhagic complications. To normalize intraocular pressure (IOP), patients underwent micropulse laser CPС. Results. After microimpulse CPС, all patients on the first day showed a decrease in IOP to an average of 26.6 mm Hg, after 7 days - up to 20.1 mm Hg. After 1 month, 7 patients (7 eyes), against the background of conservative treatment of hemophthalmos with a normalized IOP level (15-20 mm Hg), showed positive dynamics: the hemophthalmos was practically resorbed, an increase in visual acuity was achieved (from 0.3 to 0.8). In 4 patients (4 eyes) there was a decrease in the IOP level to 18-25 mm Hg. All patients underwent a successful vitrectomy with a high functional result, visual acuity ranged from 0.4 to 0.8. Conclusion. The use of micropulse laser CPС is pathogenetically justified and safe in patients with hemophthalmos in combination with high IOP. The use of this approach made it possible to achieve stable normalization of ophthalmotonus, increase the effectiveness of conservative therapy for hemophthalmos, and achieve restoration of visual functions in the examined patients.

Disorders of hemostasis occupy an important place in the structure of vascular diseases and are one of the most frequent pathological conditions encountered in practical medicine. The hemostasis system is naturally the most vulnerable system of the body. Violations of its balance are found in a wide variety of physiological and pathological conditions of the body. It is not uncommon for the first debut of decompensation to lead to an ophthalmologist. In the practice of an ophthalmologist, there are diseases when it is necessary to pay close attention to thrombophilic conditions. Changes in the hemostatic system, affect a wide range of vascular diseases of the eyeball. Recognition of the type of thrombophilia and its timely laboratory diagnosis in patients with vascular diseases of the retina and optic nerve are important in achieving the best treatment results. Multidisciplinary approach to the treatment of vascular diseases of the eyeball and modern diagnostics, including the study of hemostasis, is necessary and relevant to achieve the best clinical and functional treatment result. Timely and correct orientation of patients in vascular pathology is extremely important due to the fact that concomitant systemic pathology can aggravate the course of the disease, therefore, the choice of treatment tactics for this category of patients should be carried out in conjunction with a therapist, cardiologist, hematologist and endocrinologist.

Retinal vein occlusions are believed to have a more favorable prognosis in young patients (<50 years old) due to spontaneous regression. However, 20% of patients have a poor outcome with severe neovascular complications. The causal relationship of occlusion in this age group is still unclear in most cases. There are reports of the development of a clinical picture of retinal vein occlusion in patients with COVID-19, the formation of which is most likely due to hypercoagulation syndrome. Purpose. To present a clinical case of post thrombotic retinopathy in a young patient after COVID-19. Material and methods. A clinical example of post thrombotic retinopathy in a young patient with retinal vein occlusion. Conclusion. Management of patients with retinal vein occlusion, especially at a young age, requires a comprehensive diagnostic approach with an assessment of systemic risk factors and mandatory assessment of the initial degree of retinal ischemia according to fluorescein angiography or Optical coherence tomography angiography. The clinical criteria for the increase in retinal ischemia are a decrease in central visual acuity, macular edema, ischemic area increase, and at the later stages - retinal neovascularization and / or of the anterior segment of the eye. COVID-19 did not affect significantly the change in the parameters of the coagulogram indices. However, its effect as an aggravating factor in a patient with a genetic predisposition to vascular and microvascular diseases cannot be excluded.

Purpose. To compare the parameters of a light sensitivity (LS) of the central zone of a retina after vitrectomy due to reghmatogenous retinal detachment (RRD) with a silicone oil tamponade (SOT) and gas tamponade (GT). Material and methods. The study included 20 eyes after pars plana vitrectomy due to macula-off rhegmatogenous retinal detachment (RRD) by 25G. All patients were divided in 2 groups depending on the choice of the tamponade. The group I (10 eyes) included cases with the silicone oil tamponade (SOT) (1300 cSt), in the group II (10 eyes) – the gas tamponade (GT) (C2F6). The control group included contralateral eyes without ophthalmic pathology. All patients underwent standard ophthalmological examination and fundus- microperimetry (FMP) on the 30th day after removal of the SOT for the group I, or on the 30th day after the C2F6 tamponade for the group II. Results. According to FMP data, the parameter of average light sensitivity (LS) in the group I was significantly reduced, both in comparison with the group II (p=0.007) and the control group (p=0.003). Differentiation by zones in the group I revealed a decrease in each analyzed parameter in comparison with the control group (p<0.05) and a decrease in the 2nd zone (p=0.031) and the 4th zone (p=0.038) in comparison with the group II. In the 1st zone of the group I the formation of a relative scotoma was revealed in 4 cases out of 10 (40%). The parameters of light sensitivity (LS) in comparison with the control in the group II were significantly reduced when analyzed in each zone (p<0.05). A strong positive correlation was found between the Best Corrected Visual Acuity (BCVA) and the average LS in the group II (r=0.87). Conclusion. There is a decrease in the functional parameters of the retina with SOT compared with GT in the form of a decrease in the LS parameter in the 10° zone according to FMP data. Key words: retinal detachment, photosensitivity, microperimetry, silicone tamponade.

Purpose. To study the results of surgical treatment of patients with large diameter idiopathic macular breaks by the proposed method of closing the defect with inverted petals of the internal limiting membrane with incisions. Material and methods. There were analyzed clinical results of surgical treatment of idiopathic macular breaks (IMB) by closing the defect with inverted lobes of the internal limiting membrane with incisions in 25 patients (25 eyes) between 45 and 63 years old. Men – 11 (44%), women – 14 (56%). Terms of treatment in the hospital since the appearance of changes in visual functions: 6 patients after 1.5-2 years, 19 patients after 6-8 months. Visual acuity at admission was: 0.01 in 4 patients; 0.02 in 5; 0.03 in 5; 0.06-0.09 in 6; 0.1-0.3 in 5. Macular ruptures were stage III, diameter from 450 to 730 microns (on average, 594.52± 114.06 microns). The follow-up period is 3 years. Results. In 25 patients underwent 25G endovitreal intervention with closing of the macular hole with the petals of internal limiting membrane. The visual acuity improvement was observed in 23 patients: up to 0,1 – 0,6 – in 20; up to 0,09 – in 3. In 2 patients visual acuity was 0.01-0.02, this may be due to incomplete closure of the macular opening and the duration of the disease. After 3 years of visual function remained stable. Conclusion. The use of inverted petals of internal limiting membrane in the treatment of large diameter IMB contributes to the closure of the macular breaks and restoration of the anatomical profile of the macular in 92% of cases. The increase of visual acuity up to 0.1 – 0.6 in 80% of cases. The stability of clinical results up to 3 years allows us to recommend this method of treatment in practice.

Objective. To present the clinical and functional results of combined treatment of the complications of long-term silicone oil tamponade in a patient with retinopathy of premature. Materials and methods. A 24-year-old patient diagnosed with stage 4b retinopathy of premature in a single seeing right eye. Between 2011 and 2020 underwent 5 microinvasive revisions of the vitreous cavity with replacement of silicone oil and median duration of silicone oil tamponade of 19+25.5 months over this entire period. Because of the constant migration of emulsified silicone oil to anterior chamber due to weakness of iridolenticular ligaments, band keratopathy developed in the right eye, opacity of the IOL due to the adhesion of precipitates on its anterior and posterior surfaces, pupillary membrane, and aggravation of the proliferative membrane on the ocular surface. UCVA was proectio incerta and IOP was 17 mmHg. The median thickness of the cornea was 853 μm, the average thickness of the corneal calcifications is 57 μm. The patient underwent revision of the vitreous cavity with removal of the pupillary membrane, the next steps were to install bandage sutures in the anterior chamber parallel to iris in two mutually perpendicular surfaces to create additional barriers to silicone oil migration. Then we used 27 mg of K3-EDTA to produce 0.1% chelating solution and to remove corneal calcium deposits. Final stage was YAG – laser discision of precipitates from the IOL surfaces. Results. Postoperatively UCVA of the right eye in 1-month was 0.05, IOP was 17 mmHg and endothelial cell density was 1200 cells / mm2. According to OCT data the median corneal thickness was 640 μm, the thickness of the epithelial layer was 39 μm. Biomicroscopically, cornea was transparent, a single silicone oil vesicle in the lower segment of anterior chamver, the bandage sutures are consistent, the IOL is centered with a transparent optical zone, silicone oil visualized on the fundus, epi- and subretinal proliferates were delimited by laser coagulates, epiretinal membrane was in the macular region.

Construction of third-order schemes using Lagrange-Burmann expansions for the numerical integration of inviscid gas equations
Authors: Ворожцов Е.В.
Published: August 2021

Предлагается строить явные разностные схемы третьего порядка точности для гиперболических законов сохранения с применением разложений сеточных функций в ряды Лагранжа--Бюрмана. Результаты тестовых расчетов для случаев одномерного уравнения переноса и многомерных уравнений Эйлера невязкого сжимаемого газа подтверждают третий порядок точности построенных схем. Получены квазимонотонные профили численных решений.

It is proposed to construct several explicit third-order difference schemes for the hyperbolic conservation laws using the expansions of grid functions in Lagrange-Burmann series. The results of test computations for the one-dimensional advection equation and multidimensional Euler equations governing the inviscid compressible gas flows confirm the third order of accuracy of the constructed schemes. The quasi-monotonous profiles of numerical solutions are obtained.

Published: August 2021

Рассмотрен численно-аналитический метод решения систем обыкновенных дифференциальных уравнений,
разрешенных относительно производных от искомых функций. Метод основан на приближенном представлении решения и его производной в виде частичных сумм смещенных рядов Чебышёва. Коэффициенты рядов определяются с помощью итераций с применением квадратурной формулы Маркова. Метод может быть использован для интегрирования обыкновенных дифференциальных уравнений с более высокой точностью и с более крупным шагом дискретизации по сравнению с традиционными численными методами типа Рунге-Кутта и Адамса.

An approximate analytical method of solving the systems of ordinary differential equations resolved with respect to the derivatives of unknown functions is considered. This method is based on the approximation of the solution to the Cauchy
problem and its derivatives by partial sums of shifted Chebyshev series. The coefficients of the series are determined by an iterative process with the use of Markov's quadrature formulas. This approach can be used to solve ordinary differential equations with a higher accuracy and with a larger discretization step compared to the known Runge-Kutta and Adams methods.

Background: To evaluate the usefulness of gasless laparoscopic surgery using a Subcutaneous Abdominal Wall Lifting method (SAWL) for gynecological tumors. Methods: 5309 patients underwent gasless surgery with SAWL in our hospital between April 1993 and December 2015. Patient background as well as the number of annual cases, operation time, estimated blood loss, number of ports, blood transfusion, and shift to laparotomy were examined. With regards to Laparoscopic Cystectomy (LC), Laparoscopic Myomectomy (LM) and Laparoscopic Tubectomy (LT), we divided their cases into two stages-the first stage (FS) that we performed surgery with double-operated ports (1993-2005), and the second stage (SS) after a single-operated port surgery introduction (2008-2015) for comparison. Results: LC was the most frequently performed (2068 patients), followed by LM (1738 patients) and LT (510 patients). A single-operated port laparoscopic surgery, which we called a Gasless Reduced Port Surgery (GRPS), was introduced in 2005, and by 2008 it had accounted for almost 90% of gasless laparoscopic surgeries overall except for total laparoscopic hysterectomy. The mean operation time was significantly shorter in SS than FS for LC and LT, and it was no significant difference between two stages for LM. The estimated blood loss significantly decreased in SS compared to FS for LM and LT, and no significant difference for LC. The conversion rate in SS was 0.07%. Conclusion: GRPS is an operative procedure that is superior to the rate of conversion to laparotomy and is aesthetically superior in addition to having advantages of the conventional gasless method.
¿Arte?, ¿Documento?, ¿Política? La construcción de memoria en el cortometraje alrededor del 68 mexicano
Authors: Cossalter Javier
Published: August 2021

El cortometraje moderno latinoamericano participó de forma activa en las transformaciones del campo cultural regional entre las décadas del 50 y del 70, caracterizado por la experimentación estética, la intermedialidad y la efervescencia social. La imbricación entre arte y política suscita una serie de reflexiones en torno al film breve alrededor del 68 mexicano, objeto de estudio del presente artículo. En este sentido, el trabajo aborda los cortometrajes Comunicados cinematográficos del Consejo Nacional de Huelga (Paul Leduc y Rafael ‎Castanedo, 1968) y Mural efímero (Raúl Kamffer, 1968-1973) con el propósito de analizar su estatuto de obra estética, agente de la historia y documento social. En este caso, el registro (audio)visual de una movilización y de un acto artístico performático no solo evidencia la voluntad comunicacional de la instancia de producción en un período cercano al de su concepción, sino que vislumbra el anhelo por construir una memoria del presente. Asimismo, la eficacia de la imagen visual en tanto documento histórico –y, por ende, su carácter mnemónico– se manifiestan en la conformación de una tradición visual y en la recuperación y puesta en valor patrimonial de estas obras, desde entonces hasta la actualidad. Por tal motivo, el artículo examina también un film mexicano contemporáneo que retoma las imágenes acerca del movimiento estudiantil, con la intención de confirmar tales premisas.
El diario La Nación versus el sindicalismo argentino La construcción de un enemigo "subversivo" de la democracia (1983-1987)
Authors: Díaz César Luis , Giménez Mario Jorge
Published: August 2021

En este artículo se examina la posición editorial del diario La Nación sobre el comportamiento del sindicalismo durante el Gobierno de Raúl Alfonsín, entre los años 1983 y 1987. Considerando al diario como actor político, se examinarán sus estrategias discursivas, se identificará al o a los destinatarios a los cuales dirigía su mensaje y la utilización de los recursos retóricos de los cuales se valía para enunciar el accionar sindical. El diario, exponente del pensamiento liberal, cuestionó las políticas estatistas del peronismo, como también la sindicalización masiva de trabajadores ocurrida a partir de 1945. Uno de los motivos por los cuales contribuyó con el golpe cívico-militar de 1976 estuvo relacionado con la restauración del “orden”. Dado que consideraba al movimiento obrero responsable de su pérdida, avaló las medidas punitorias ejecutadas por la dictadura que, inspiradas en la doctrina de la seguridad nacional, tuvieron como resultado la intervención a los gremios, la desaparición, el presidio y el exilio de numerosos dirigentes sindicales. Después de la derrota en la guerra de Malvinas, destinaría una importante cantidad de editoriales para oponerse a las medidas de fuerza ejecutadas por las entidades representativas de los trabajadores, acusándolas de atentar contra la democratización y la convivencia social. Una vez asumidas las autoridades elegidas por el pueblo, seguiría fustigando el comportamiento de gremialistas, descalificando su metodología de lucha por considerarla contraria a la estabilidad de la democracia y el régimen representativo y republicano. Por esa razón, no dudó en reputar como subversiva la actitud del sindicalismo argentino.
Simplificación de la políticaRepercusión mediática de las sesiones de control al Gobierno de España en informativos de TVE y Telecinco
Authors: Gil-Torres Alicia , Martinez de la Huerta Elena , San José-de la Rosa Cristina
Published: August 2021

Este trabajo se propone estudiar la simplificación de la política en los informativos, mediante un análisis sobre la repercusión mediática de las cinco primeras sesiones de control al Gobierno de España en su XIV Legislatura en los telediarios de las 21 horas de TVE (canal público) y Telecinco (líder de audiencia en esa franja horaria y de carácter privado). A través de una plantilla de análisis de carácter cualitativo ad hoc, se recogieron datos de las sesiones de control y de las piezas de los noticieros de las dos cadenas. Así, se pretende descubrir diferencias en las informaciones emitidas y si, además, estas cadenas buscan contar la información más relevante de estos mecanismos de control o si optan por la anécdota. Los resultados arrojan diferencias significativas que ponen de manifiesto una marcada simplificación de la política en nuestros días, tales como el tiempo dedicado en los informativos, el número de preguntas o respuestas mostradas, la atención a la figura política más controvertida –aunque no sea relevante– y dar más importancia al cómo que al qué se dice. Esto último se refleja en la primacía del cara a cara entre diputados por su efectismo en los telediarios. TVE prefiere mostrar la parte más formal de las sesiones plenarias de manera más relajada que Telecinco, que opta principalmente por la emisión de imágenes de “acción” en el hemiciclo. De esta manera, a través de un análisis cualitativo que toma como ejemplo uno de los mecanismos más importantes de control al Gobierno y su repercusión en los informativos, se demuestra cómo la simplificación de la política es una realidad y se cubre, así, un vacío académico en España.
Los deportes electrónicos en la Argentina. Entre industrialización incipiente y espíritu de época
Authors: Kohan Adrián Enrique
Published: August 2021

Los deportes electrónicos son un fenómeno mediático-cultural cuya insipiencia, no solo a nivel global, sino particularmente a nivel local, nos permite abordar el desarrollo de procesos de industrialización, mediatización e intermediación de nuevos productos de consumo cultural. Con esta perspectiva como punto de partida, y desde una estrategia metodológica cualitativa, examinamos paralelismos entre este y otros fenómenos, en particular con el fenómeno youtuber/influencer, que lo precede casi genealógicamente. Este examen arroja luz sobre ciertos anclajes del proceso en cuestiones que hacen a la cultura empresarial y emprendedora, a la centralidad de las estructuralidades y la idea de orden y jerarquía y a modelos de liderazgo que se alejan de lo carismático para dar hacer lugar a lo legal. Con esto entendemos a los procesos de industrialización de los deportes electrónicos como una posible evidencia de –o al menos invitación a la reflexión sobre– un regreso a formas de hacer industria cultural más propias de lo moderno que de lo posmoderno, e incluso, quizás, reflejo de un nuevo espíritu de época.
From Standing Rock to flint and beyond
Authors: Harrison Faye V.
Published: August 2021

Protests against the Dakota Access Pipeline led by water protectors from the Standing Rock Sioux Tribe in North Dakota have brought human rights violations related to Indigenous sovereignty, environmental justice, and sustainable development into the foreground of political debate in the United States. The struggle at Standing Rock has been strengthened by a coalition formed with activists from other Indigenous Nations, including representatives from the Amazon Basin, and from non-Indigenous movements and political organizations such as the Green Party and #BlackLivesMatter. This article reflects upon the centrality of Indigenous Sovereignty within the broader struggle for human rights and democracy in their most inclusive and substantive senses, especially in societies whose development has been built upon the violence of colonial expansion, white supremacy, and heteropatriarchy. The article also situates Indigenous rights within regimes of multiple articulated alterities in which the subjugation and dispossession of Indigenous and Afro-descendant peoples have been historically differentiated yet intertwined in the Americas. The article offers a multi-sited framework for understanding the convergent and divergent points of reference in the logics of Indigenous and Afro-descendant identity, the relationship with the State and Market, and connections to the material and spiritual resources of land. Attention is directed to cases in the United States, Honduras, and Suriname (including those of communities that define themselves as “Afro-Indigenous”) in which some notion of common ground, affinity, or alliance with past or present-day Indigenous peoples has been mobilized in Afro-descendants’ collective claims on rights to land, development, and cultural resources.
Movimento ambientalista na China contemporânea:
Authors: Barbieri Mariana Delgado
Published: August 2021

Este artigo busca apresentar uma reconstrução histórica do desenvolvimento do movimento ambientalista, a partir da compreensão da estruturação e funcionamento das ONGs ambientalistas. Apresentamos um breve panorama da questão ambiental na China e das políticas ambientais governamentais. A partir desses elementos é possível refletir sobre o papel das ONGs na contemporaneidade, sua posição de diálogo com o Estado e sociedade, exemplificados a partir dos protestos ambientalistas e da atuação pública em dois casos distintos de construção de hidrelétricas. É observável uma mudança na postura do governo chinês com relação ao movimento ambientalista nas últimas três décadas, evidenciando uma maior incorporação de suas reivindicações, sendo possível considerar as ONGs como um novo ator social ativo na política ambiental chinesa. Utiliza-se a noção de sociedade de risco e governança ambiental multiator como princípio teórico para se analisar o objeto de estudo deste artigo, a partir do uso de fontes primárias e secundárias.
