Published: June 2019

Since the 90s, quiet areas have commonly been considered as places to be acoustically preserved or where acoustic interventions should be implemented to reduce noise levels. With the enforcement of the Environmental Noise Directive in 2002, a formal definition of a ‘quiet area in agglomeration’ and a ‘quiet area in open country’ was established. However, many Member States complained about the absence of guidelines regarding the identification and management of quiet areas. The LIFE QUiet Areas Definition and Management in Action Plans (QUADMAP) project started in 2011 to contribute to the Directive’s incomplete requirements for quiet areas. The project’s main result has been the introduction of a flexible methodology for the selection, analysis and management of quiet areas in agglomeration in which both acoustic and nonacoustic parameters are evaluated. The current paper illustrates the analyses carried out on the data collected during the application of the selection, analysis and management phases of the developed methodology in the different pilot cases selected during the Project. Mentioned analysis are aimed at verifying the benefits of the proposed complementary selection criteria (‘relative quiet urban areas’ identification criteria and ‘homogeneous urban areas’ subdivision criteria), at defining the measurement periods most representative of the areas and the acoustic and nonacoustic parameters to be considered as the most significant.
Performance Characteristic Modeling for 2D Compressor Cascades
Authors: Fei Teng , Ji Lucheng , Yi Weilin
Published: June 2019

The flow field in a compressor cascade is very complex owing to the highly 3D, turbulent, and viscous properties. However, in the through-flow analysis method, the viscosity effects are taken into account using empirical models. These models were based on experimental results for early blades. However, the blade types in modern compressors are quite different from those in older compressors. Therefore, it is not possible to predict the performance of modern compressors using the old empirical models. In this study, several multiple circular-arc (MCA) blades commonly used in modern compressors were simulated. After the simulations, a database of the cascade performance was built. Based on this database, some new models were established to predict the performance of modern cascades using regression analysis methods and an artificial neural network (ANN) method. The accuracy of all these new models is high enough for use in engineering applications.
Series: Cardiovascular outcome trials for diabetes drugs Saxagliptin and SAVOR-TIMI 53
Authors: Fisher Miles
Published: June 2019

SAVOR-TIMI 53 was the first FDA-mandated cardiovascular outcome trial to be presented and published. It compared saxagliptin and placebo in 16,492 patients with type 2 diabetes. SAVOR-TIMI 53 demonstrated non-inferiority for major cardiovascular events (cardiovascular death, myocardial infarction, stroke) but not superiority. An unexpected statistically significant increase in adjudicated hospitalisation for heart failure was seen in the saxagliptin group. Post hoc analysis demonstrated that subjects at greatest risk for hospitalisation for heart failure had previous heart failure, an estimated glomerular filtration rate <60 mL/min, or elevated baseline levels of N-terminal pro-B type natriuretic peptide. As other dipeptidyl peptidase 4 (DPP-4) inhibitors are available which have not been associated with an increased risk of hospitalisation for heart failure, saxagliptin should be avoided in patients with heart failure or a reduced estimated glomerular filtration rate.

Published: June 2019

Foot infections are the commonest complication of diabetes mellitus requiring hospitalisation. Despite local osteomyelitis being the most frequent sequel of a diabetic foot infection, there is emerging evidence to suggest that local disease may lead to distant infections. In this report we present a case of recurrent thoracic spine spondylodiscitis due to left hallux osteomyelitis in a man with type 2 diabetes. This case illustrates the importance of considering spondylodiscitis as a differential diagnosis in patients presenting with diabetic foot infection and complaining of acute severe back pain.

Estradiol is a key factor for tumorigenesis and prognosis of hormone receptor-positive breast cancer. Adipocytes are one source of estradiol in patients with breast cancer. Recent studies have shown that phosphorylated ribosomal protein S6 kinase-1 plays a critical role in adipogenesis. Therefore, estrogen depletion therapy might have beneficial effects in phosphorylated ribosomal protein S6 kinase-1-positive breast cancer. This study was conducted to evaluate the value of phosphorylated ribosomal protein S6 kinase-1 as a marker for gonadotropin-releasing hormone agonist treatment, a form of estrogen depletion therapy, for premenopausal patients with HR-positive, human epidermal growth factor receptor 2-negative breast cancer. We reviewed the medical records of 296 premenopausal patients with hormone receptor-positive, human epidermal growth factor receptor 2-negative primary invasive breast cancer treated between 2008 and 2015. Phosphorylated ribosomal protein S6 kinase-1 positivity was defined by immunohistochemical staining scores of 1+, 2+ and 3+, whereas a score of 0 was considered negative. Phosphorylated ribosomal protein S6 kinase-1-positive tumors were found in 74.0% of the patients. In the phosphorylated ribosomal protein S6 kinase-1-positive group, disease-free survival of patients treated with a gonadotropin-releasing hormone agonist was significantly longer than that of patients treated without a gonadotropin-releasing hormone agonist (mean 106.7 months vs mean 91.1 months, P = 0.018). Phosphorylated ribosomal protein S6 kinase-1 is a potential biomarker for predicting the efficacy of gonadotropin-releasing hormone agonist therapy in premenopausal patients with hormone receptor-positive, human epidermal growth factor receptor 2-negative breast cancer.
Skeletal effects of nongenomic thyroid hormone receptor beta signaling
Authors: Lindsey Richard C , Godwin Catrina , Mohan Subburaman
Published: June 2019

Thyroid hormone (TH) levels increase rapidly during the prepubertal growth period in mice, and this change is necessary for endochondral ossification of the epiphyses. This effect of TH on epiphyseal chondrocyte hypertrophy is mediated via TRβ1. In addition to its traditional genomic signaling role as a transcription factor, TRβ1 can also exert nongenomic effects by interacting with other signaling molecules such as PI3K. To investigate the role of nongenomic TRβ1 signaling in endochondral ossification, we evaluated the skeletal phenotype of TRβ147F mutant mice which exhibit a normal genomic response of TRβ1 to TH, but the nongenomic response through the PI3K pathway is impaired. Using microCT, we found that 13-week-old TRβ147F mice had significantly less trabecular bone mass at three sites. Histomorphometric analyses revealed that mineralizing surface to bone surface and BFR/BS were reduced in the mutant mice. Mechanistically, we found that activation of TRβ increased Alp and Osx expression in control but not TRβ147F osteoblasts. Since canonical β-catenin signaling has been implicated in mediating nongenomic TRβ–PI3K signaling, we evaluated the effect of TRβ1 activation on β-catenin target gene expression in MC3T3-E1 pre-osteoblasts. We found that β-catenin target genes were increased, suggesting that nongenomic TRβ1–PI3K pathway modulation of β-catenin signaling may mediate TRβ1 effects on osteoblast differentiation. Together, these results suggest that TH acting through TRβ1 regulates endochondral ossification in part via nongenomic signaling in mice. Further investigation of this nongenomic mechanism of TRβ1 signaling could lead to novel therapeutic targets for treatment and prevention of osteoporosis.
Un jardín de lluvia para la remoción de nitrógeno de la escorrentía en ciudades tropicales
Authors: Fajardo-Herrera Reinaldo J. , Valdelamar-Villegas Juan C. , Mouthon Bello Javier
Published: June 2019

Los jardines de lluvia son depresiones del suelo cubiertas con plantas, ubicados estratégicamente en ciudades, para capturar el agua proveniente de la escorrentía pluvial, evitando así la entrada de contaminantes y de nutrientes en exceso a los ecosistemas acuáticos. A pesar de su importancia, la implementación de este tipo de tecnología en ciudades costeras tropicales es escasa; debido a esto se construyó un jardín de lluvia a escala, en las instalaciones de la Universidad de Cartagena, Colombia, para determinar las tasas de eliminación de compuestos nitrogenados (nitritos, nitratos, TKN, amoniaco y nitrógeno (N) total) presentes en la escorrentía pluvial simulada, con una concentración de 25 mg de N/L de agua. Los resultados muestran que el modelo de jardín de lluvia propuesto, puede reducir exitosamente los niveles de nitrógeno siempre que la escorrentía que ingresa al sistema no supere 0.91 L/min/m2, por lo anterior este diseño representa una alternativa para el manejo de la escorrentía pluvial cargada de compuestos nitrogenados en ciudades tropicales.
The effect of artificial forest plantations on the thermophysical properties of chernozems
Authors: Gorban V. A.
Published: June 2019

As a result of a study of the effect of artificial forest plantations formed by Robinia pseudoacacia L. and Quercus robur L., on the thermophysical features of the chernozems of the Komissarovsky reserve (Pyatykhatsky district, Dnepropetrovsk region, Ukraine), it was found that the stand of robinia reduced air temperature by 4, 5 °С, oak – by 9.4 °С in comparison with the open area. The maximum temperature of the soil surface is found in ordinary chernozem. The effect of robinia plantation manifested itself in the form of a decrease in the temperature of the soil surface by 5.4 °C, and the oak surface by 8.0 °C. The maximum soil temperature at a depth of 50 cm is also found in ordinary chernozem. At the same depth, the soil under robinia plantation turned out to be 7.6 °C, under oak – 6.9 °C colder. According to the average temperature of the 50-centimeter layer of all the studied soils, ordinary chernozem is distinguished, the soils under the plantations almost do not differ according to this indicator. The smallest difference between the air temperature and the average temperature of the soil layer 0–50 cm was in the soil under oak plantation, the largest – in the soil under robinia plantation. The smallest difference between the temperature of the soil surface and at a depth of 50 cm was found in the soil under oak plantation, and the greatest difference in the soil under robinia plantations. Based on the analysis of the results obtained, an assumption was made about the thermal features of the upper horizons, which fall within the interval of 0–50 cm, of each of the three studied soils. The soil under robinia plantation is characterized by maximum values of thermal diffusivity, and ordinary chernozem – minimal. The soil under the oak plantation occupies an intermediate value for this indicator. Ordinary chernozem is characterized by maximum values of heat capacity, slightly smaller values are characteristic of soil for robinia plantations. The minimum values of heat capacity are characteristic of oak plantation soil. The soil under robinia plantation is sharply distinguished by the maximum values of thermal conductivity compared to ordinary chernozem and the soil under oak planting. The actual study of thermophysical properties confirmed the correctness of the assumption in only one of the three indicators for each of the studied soils. This indicates a significant limitation of predicting the thermophysical indicators of soils, based only on measuring their temperature. The influence of robinia plantation on the thermal physical properties of ordinary chernozems is manifested in an increase in their thermal diffusivity and thermal conductivity, as well as in a certain decrease in heat capacity. The influence of oak stands is characterized by an increase in thermal diffusivity and heat capacity, as well as a decrease in thermal conductivity of ordinary chernozem.

Abstract. Three new species of the genus Lepanthes from the Alto de Ventanas ecoregion in the central Andes of Antioquia, Colombia, are described and illustrated. Lepanthes sabinadaleyana is similar to L. lycocephala but it is distinguished by the narrowly ovate leaves and the lip with oblong-obovate blades with an ovoid, obtuse appendix. Lepanthes cissyana is similar to L. ballatrix, but it differs by its purple lip with elliptical blades and a semicircular, concave body with two long, pubescent appendices in the sinus. Lepanthes dougdarlingii is similar to L. hortensis but can be distinguished by the prolific habit and the appendix of the lip lingulate to oblong, pubescent, with a concave depression in the middle, an apical glandlike structure and a tuft of hairs on the abaxial surface near the apex.
Orthogonal Turbine for Free Rivers and Channels
Authors: Lyatkher V. M.
Published: June 2019

The paper discusses the problem of using the energy of rivers without creating the dams and flooding vast areas and notes that there is a progress in the implementation and development of the ideas of patent in 1931 (the speed of the workers turbine blades is higher than flow rate). The paper gives the diagrams of the new turbines of this type, for example a balanced 6-tier single-blade turbine, turbine-spiral, a balanced twoblades turbine. Moreover, the paper deals with the features free-threaded orthogonal turbines in the streams of the limited width and depth. The most important characteristic of a turbine is the turbine's power factor that is equal to the ratio of the energy of the rotating turbine to the kinetic energy of the flow in the current tube passing through the turbine circuit. There is a possibility of a significant increase in the power of the turbine in comparison with the conditions of use unlimited streams. The increase in turbine power in a straitened flow is associated with an increase in the flow velocity in the turbine on the approach to the rear section of the blades’ track. It is set the requirements of the turbine parameters for maximum power at a given water flow and the permissible level rise in the river. These requirements relate to the certain rules for selecting the number of blades (and solidity) of the turbine, taking into account the permissible increasing in the water level (backup) in front of the turbine. The paper notes the turbines instability at low speed of rotation, describes a turbine design modification that eliminates this drawback. Modification of the high-speed orthogonal turbines is the use of accelerating blades with a cup-shaped cross-section, placed on the route within a diameter 2 times smaller than the diameter of the main (working) blades of the smoothly streamlined profile. It is concluded that all considered variants of turbines for streams with limited cross-section, the design of the blade system may be made rigid, which eliminates the single central shaft (axle), replacing it with a reference semi-shafts.

Published: June 2019

The diversity of endomycorrhizal fungi in the rhizosphere of Crocus
sativus has been studied at five sites in the Taliouine region
(Tinfat), located in Taroudant Province (Morocco), according to the number of
years of soil exploitation by Saffron cultivation. In all sites, the roots of
Crocus sativus carry structures of endomycorrhizal fungi.
Root mycorrhizal frequencies are very high in site 1 (93.33%); site 2 (96.67%);
site 4 (90%) and in site 6 (93.33%). In these sites, the spore density is,
respectively, 39, 58, 138, 99 spores / 100 g of soil. The frequency of root
mycorrhization is lower at the site (76.66%) which also exhibited a spore
density of 27 spores / 100 g of soil.

The identification of isolated spores made it possible to note the presence of 36
species belonging to 6 genera: Glomus (15 species),
Acaulospora (10 species), Scutellospora (6
species), Gigaspora (2 species), Pacispora (2
species), Entrophospora (1 species). Species such as
Glomus clarum, G. etunicatum, G.
aggregatum, G. intraradices, Acaulospora
laevis, Scutellospora coralloidea, were present in
all studied sites.

The greatest richness of MA fungi was registers in the site at four successive
years of exploitation by Saffron (24 species), with a Shannon diversity index H
‘= 2.82 which is the highest among all studied sites, followed by the site at
six years of occupation by Saffron (21 species), with H ‘= 2.61, while the
lowest number of species was recorded in sites of two, three and ten years of
exploitation of sol by Saffron, with H ‘= 1.77, respectively; 2.12 and 2.44.

This decrease in endomycorrhizal species richness confirms that Crocus
sativus residues are probably the cause. In fact, the prolonged
occupation of plots with safrana has an allelopathic effect on mycoflora and on
the yield of Saffron.
The comparison of probiotic monocultures influence on organochlorine pesticides changes in fermented beverages from cow and goat milk during cold storage
Authors: Agata Witczak Agata , Mituniewicz-Małek Anna
Published: June 2019

The effect of selected probiotic monocultures addition as a method of organochlorine pesticides (OCP) residues reduction in fermented beverages manufactured from cow and goat milk during cold storage was examined. Supplementation of traditional yogurt starter by single monoculture or a mixture of two monocultures has resulted in a decrease of OCPs in products during cold storage. Extension of the cold storage period up to 14 days resulted in further losses in the content of the analysed compounds. Regardless of the milk type used for beverage production, beverages prepared from the mixture of two monocultures (Lb.
acidophilus LA-5 and Bifidobacterium BB-12) showed significantly greater decrease of pesticides content in comparison to beverages containing only LA-5. The maximum decrease (from 5.39 % to 20.7 %) in OCP was determined during the 14-day cold storage, and was few percent higher in beverages manufactured from goat milk.

Authors: Altuntas Seda , Korukluoglu Mihriban
Published: June 2019

The selection of proper probiotic culture is essential for maintaining adequate numbers of viable cells until consumption since potential adverse interaction between selected strain and starter culture. This study examined the suitability of Cacık as a potential probiotic carrier
including Lactobacillus acidophilus 74-2, Lactobacillus rhamnosus Howaru HN001TM and Bifidobacterium longum BB536 in different combinations. The presence of three probiotic strains caused higher post
acidification and shorter fermentation time associated to higher counts
of L. bulgaricus. Except for certain combinations containing B. longum BB536, the counts of individual probiotic bacteria were higher than 6 log g-1 for all probiotic supplemented Cacık samples. Results showed that bacterial interaction was decisive for survival over 21 days of storage. Probiotic products containing only B. longum BB536 or B. longum
BB536 with L. acidophilus 74-2 did not accomplish in terms of the technological point, since the viable cell counts decerased for 2.45 log
and 1.95 log per g, respecitevly, throughout the storage period. In three of totally four combinations included L. rhamnosus Howaru HN001TM alone or combined with other probiotic bacteria, the viable cell counts of L. rhamnosus Howaru HN001TM remained at the inoculated level, while the counts significantly increased in co-culture with L. acidophilus 74-2. Considering the overall sensorial attributes and survival of probiotics, Cacık supplemented with L. rhamnosus Howaru HN001TM alone, combinations of B. longum BB536 and L. rhamnosus Howaru HN001TM or L. acidophilus 74-2 and L. rhamnosus Howaru HN001TM or by all of the three tested probiotics, were suggested as suitable for further production.

Trajetória da formação em relações públicas no Brasil
Authors: Grohs Ana Cristina Da Costa Piletti
Published: June 2019

O reduzido número de obras e autores dedicados à pesquisa da educação superior das Relações Públicas no Brasil dificulta o entendimento sobre a formação universitária destes profissionais. Com o objetivo de conhecer o estado da arte do processo ensino-aprendizagem das Relações Públicas, foi realizada uma revisão da literatura especializada e um balanço dos artigos publicados nos principais periódicos e anais de eventos da área no decorrer de 15 anos. Verificou-se que o tema ensino-aprendizagem das Relações Públicas ainda é pouco explorado como objeto de pesquisas acadêmico-científicas. Concluiu-se que a histórica busca pela legitimidade da profissão e pelo reconhecimento do valor estratégico das atividades de Relações Públicas nas organizações permanece. Alia-se a isso o distanciamento entre teoria e prática. Tal realidade é agravada pela contínua diminuição no número de cursos de graduação no Brasil e a crise de identidade que ainda preocupam acadêmicos e profissionais da área.
Socialt rum og symbolsk magt

Published: June 2019

Jeg vil, inden for rammerne af en forelæsning, forsøge at præsentere de teoretiske principper, som ligger bag den undersøgelse, hvis resultater præsenteres i La Distinction (Bourdieu, 1979), og trække visse af de teoretiske implikationer frem, som med størst sandsynlighed vil forvirre læseren, især her i USA på grund af forskellene i vore kulturelle traditioner. Hvis jeg skulle karakterisere mit arbejde i få ord, dvs., som det så ofte gøres nu om dage, sætte en etiket på det, vil jeg tale om konstruktivistisk strukturalisme eller om strukturalistisk konstruktivisme, hvor ordet strukturalist skal tages i en ganske anden betydning end i Ferdinand de Saussures eller Claude Levi-Strauss'tradition. Med strukturalisme eller strukturalist mener jeg, at der i selve den sociale verden, og ikke kun i symbolske systemer, såsom sprog, myter etc., eksisterer objektive strukturer, som er uafhængige af agenternes bevidsthed og ønsker og er i stand til at lede eller tvinge deres praktikker eller deres repræsentationer. Med konstruktivisme mener jeg, at der finder en social genese sted: På den ene side af de opfattelses-, tænke- og handlemønstre, som konstituerer det jeg kalder habitus, og på den anden side af de sociale strukturer, og i særdeleshed af det, jeg kalder felter og grupper, og som almindeligvis kaldes sociale klasser.
Compacted Brazilian soil hydraulic behaviour during the percolation of petroleum-produced water
Authors: Lima Fernando A L V , Machado Sandro Lemos
Published: June 2019

This paper analyses the results of column tests performed on samples of compacted soils permeated by petroleum-produced water from onshore areas in north-east Brazil. It is shown that in almost all of the tested samples, the soil hydraulic conductivity decreased over time. Bioclogging and biofilm formation, as well as clay dispersion and filtration, are analysed; clay dispersion is indicated as the probable main cause of the observed behaviour. Furthermore, particle dispersion seems to be dependent on the changes in soil porosimetry (lower fraction of macropores), which is caused by higher compaction energy. Breakthrough curves obtained for magnesium (Mg) and calcium (Ca) suggest that bivalent cations were replaced by sodium (Na) cations during the tests. Furthermore, for longer test times, a noticeable amount of solid-particle sediment was observed at the bottom of the fluid collection jars. The authors confirmed that bioclogging did not significantly influence the reduction in soil hydraulic conductivity, as this reduction occurred before the start of any microbial activity.

How does the interaction of macroprudential and monetary policies affect cross-border bank lending?
Authors: Takats Elod , Temesvary Judit
Published: June 2019

We combine a rarely accessed BIS database on bilateral cross-border lending flows with cross-country data on macroprudential regulations. We study the interaction between the monetary policy of major international currency issuers (USD, EUR and JPY) and macroprudential policies enacted in source (home) lending banking systems. We find significant interactions. Tighter macroprudential policy in a home country mitigates the impact on lending of monetary policy of a currency issuer. For instance, macroprudential tightening in the UK mitigates the negative impact of US monetary tightening on USD-denominated cross-border bank lending outflows from UK banks. Vice-versa, easier macroprudential policy amplifies impacts. The results are economically significant.
Educación Intercultural Bilingüe en Ecuador: Una revisión conceptual
Authors: Vernimmen Aguirre Guadalupe María
Published: June 2019

El artículo explora los desafíos de la Educación Intercultural Bilingüe en Ecuador. Para ello, revisa brevemente la historia de las luchas y resistencias de los movimientos indígenas por educarse en una lengua ancestral desde sus inicios hasta llegar a la institucionalización del Sistema de Educación Intercultural Bilingüe (SEIB) en el año 1988. En este sentido, destaca en distintos momentos, la participación de organismos religiosos, así como la cooperación de organismos internacionales. Posteriormente, el análisis hace énfasis en el gobierno del eco. Rafael correa delgado (2007-2017), además de la legislación y literatura académica correspondiente al tema, el trabajo demuestra que el anterior Gobierno de la República del Ecuador, supuso el impulso de políticas públicas al reconocer los derechos de las trece nacionalidades legítimas, y de todas ellas, las lenguas más extendidas: kichwa y shuar, no obstante, en la práctica es compleja la aplicación de políticas públicas en pro de la educación intercultural, incluyendo la educación en lengua ancestral y en español, con ello se logra verificar que se avala una educación más multicultural que intercultural. Finalmente, se revisa el concepto de interculturalidad, y se ofrecen recomendaciones para la implementación de políticas públicas culturales que avalen la interculturalidad y el bilingüismo como proyecto político y epistémico para el desarrollo social en Ecuador.
Экономический кризис и оценка эффективности власти: кто несет ответственность за ухудшение уровня жизни в России?
Authors: Сироткина Елена Викторовна , Семенов Андрей Владимирович
Published: June 2019

Винить или не винить власть за последствия экономического кризиса? Если обвинять, то кого граждане считают ответственным за проблемы в экономике в первую очередь? Мы предполагаем, что кризис и оценка эффективности работы органов власти связаны логикой атрибуции ответственности, то есть способностью людей определять центры принятия решений и устанавливать связь между политическим курсом и изменениями в реальности. На основе материалов всероссийского опроса общественного мнения и фокус-групповых дискуссий мы устанавливаем, что логика атрибуции ответственности по-разному проявляется в оценках эффективности работы президента, правительства и думы. Результаты нашего исследования показывают, что коллективные органы с непопулярными политиками – Государственная дума и правительство – наделяются наибольшей ответственностью за ухудшение уровня жизни. Эти институты «принимают удар» на себя и становятся символическимвиновником неэффективной политики и ее последствий. На фоне высокого уровня фрустрации и недовольства работой думы и правительства, фигура президента остается вне критики граждан. Результаты его работы либо редко, либо вообще не связывают с кризисом. Анализ фокус-групповых дискуссий показал, что недостаток когнитивных ресурсов, институциальная непрозрачность и низкое качество политически релевантной информации ограничивают возможности людей адекватно оценивать работу органов власти и наделять ответственностью за политический курс. Проблемы с адекватной атрибуцией ответственности, в свою очередь, имеют серьезные следствия с точки зрения подотчетности и изменения политического курса. Не представляя кто несет ответственность за политические решения, люди не могут определить необходимые изменения в направлении политических действий. В таком случае не только «институциальная ясность» в распределении полномочий будет играть важную роль, но и качество медийной среды, выступающей основным проводником сведений о политике.
Идентичность заводского рабочего в постсоветском контексте: этнографическое кейс-стади района Уралмаш
Authors: Полухина Елизавета Валерьевна , Ваньке Александрина Владимировна
Published: June 2019

Статья обращена к изучению идентичности представителей рабочего класса. Исследование основано на концепции культурологического анализа классов и подходе генетического структурализма Пьера Бурдье, согласно которому классовый габитус представляет собой систему устойчивых диспозиций, порождающих социальные практики и встроенных в социальные отношения. Эмпирическим объектом исследования выступают рабочие Уралмашзавода – одного из крупнейших заводов СССР, который продолжает функционировать и сегодня. Исследование проходило на территории района Уралмаш, построенного в 1920-е гг. в городе Свердловск (ныне Екатеринбург). Полевое исследование выполнено в жанре этнографического кейс-стади. Во время сбора данных, в мае-июне 2017 г., коллектив исследователей во главе с авторами статьи стали временными жителями района Уралмаш. На примере уральского кейса показано, что современный заводчанин на постсоветском пространстве является носителем множественной и фрагментарной идентичности, в которой объединяются «советские» и «постсоветские» практики и ценности. Рабочие описывают себя в категориях «простые люди», «хороший человек», через личные качества и ценности такие, как «честность», «трудолюбие», «общительность», «достоинство», «простота», а также идентичности частной жизни, вне сферы труда (семьянин, пенсионер, садовод). Многие представители старшего поколения осознают себя как люди, «живущие в прошлом», «советские» люди. Таким образом, для старшего поколения заводчан советское прошлое по-прежнему остается главным ресурсом и универсальной опорой, которая поддерживает их самовосприятие. Смыслообразующим ресурсом для идентичности уралмашевцев является «районный» патриотизм. Однако, как показывают данные наших наблюдений и интервью, рабочие в постсоветское время становятся все более «невидимой» группой в районе и, в силу сложившихся привычек, отказываются перенимать новые стили жизни, предлагаемые пришедшими в район новыми акторами (застройщики, культурные деятели, представители инфраструктуры развлечений). Кроме того, работник завода в постсоветском времени утрачивает классовую идентичность, характерную для советского периода. В результате рабочие воспроизводят или заново присваивают иные идентификационные типы, но сохраняют при этом память о советском прошлом и пытаются найти основания для идентичности вне сферы труда, в приватной, непубличной жизни.
The Media’s Construction of LGBT Pride Parades in Russia
Authors: Семыкина Ксения Сергеевна
Published: June 2019

This article analyses media representations of LGBT social movements, taking the case of Saint Petersburg LGBT pride parades. The analysis is developed through the use of framing theory, which views the media as an arena where interest groups promote their own interpretations of particular issues. Frames juxtapose elements of the text in such a way as to provide the audience with a scheme within which to perceive the message. Social movements are viewed as interest groups that introduce new frames in public debate. Two types of frames can be distinguished: collective action frames and status quo frames. In this study, the usage of two collective action frames (equality frame and victim frame), and two status quo frames (morality frame and propaganda promoting homosexuality frame) were examined. Additionally, the sources of quotes used in news stories were analyzed. The study focuses on articles dedicated to Saint Petersburg LGBT pride marches in the years 2010–2017 in the most popular local Internet websites. The analysis shows that the coverage of LGBT pride marches can be divided into two distinct periods: 2010–2013 and 2014–2017. In the first period, LGBT activists dominated the coverage, quoted about twice as much as government officials. Equality and victim frames were prevalent. In the second period, activists were cited significantly less often, with the propaganda promoting homosexuality frame dominating the discourse. However, contrary to findings of previous studies on social movement representation, across the whole period under consideration, LGBT activists were quoted more often than government representatives. This finding calls for a further exploration of the conditions which allowed for such coverage in the context of political heterosexism and homophobia.
