Authors: Capurro Leandro , Brugnoli Ernesto , Díaz-Ferguson Edgardo , Martínez Claudio
Published: April 2023

Limnoperna fortunei (golden mussel) is an invasive mollusk, native to Southeast Asia. The detection of L. fortunei, during early stages of the invasion, is an interesting strategy for its control and eradication. For these aims, traditional methods are used based on identifying the species in samples of zooplankton or benthos community. In addition, molecular methods based on the detection of DNA in different environmental samples (eDNA) have been proposed. We describe and discuss a protocol developed for the detection of L. fortunei based on mitochondrial eDNA in plankton samples from freshwater systems. Water samples were obtained during 2018-2019, from cooling systems of the hydroelectric power plant in Río Negro, Uruguay. eDNA was detected by end-time PCR and PCR products were resolved on polyacrylamide gels and silver staining. Primers specificity was determined in related limnic and brackish native species. Sensitivity was analyzed as genomic DNA concentration and number of larvae. Different methodologies were tested to remove inhibitors from samples. Finally, the eDNA PCR products were sequenced to confirm the specificity of the reaction. The results obtained by molecular techniques were more sensitive than traditional methods of species detection.

The Covid-19 pandemic has resulted in significant and far-reaching economic impacts on a global scale. This paper presents a comprehensive analysis of the effects of Covid-19 on the global financial crisis from multiple perspectives. To do so, we review the existing literature on the crisis and its impact on the global economy and present a preliminary analysis of its causes and effects. We propose a set of methods for studying the crisis in greater detail and present the results of our experiments. Our findings indicate that Covid-19 has led to macroeconomic impacts such as decreased global GDP, higher unemployment rates, and a decline in international trade. At the industry-specific level, the pandemic has had varying impacts across different sectors, with some industries, such as travel and tourism, being hit particularly hard. Government responses to the pandemic have also varied, with some countries implementing more effective policies than others. Supply chain disruptions have affected industries globally, and long-term effects of the pandemic are expected to be far-reaching. Our analysis reveals the complex and evolving impact of Covid-19 on the global financial crisis, highlighting the need for interdisciplinary perspectives to fully understand the issue. We also discuss the implications of our findings, including the potential for future research to inform policy decisions aimed at mitigating the impact of Covid-19 on the global economy. In general, our study provides a comprehensive perspective on the impact of Covid-19 on the global financial crisis, highlighting the need for continued research and collaboration across disciplines to fully understand the extent of the pandemic's economic impacts and inform effective policy responses.

Authors: Dewi Wardhani Utami , Nisa Khoirin , Usman Mustofa
Published: May 2023

In everyday life there are many complex and global problems, especially in terms of decision making. Machine learning (ML) which is built from the concepts of computer science statistics and mathematics can automatically solve problems without guidance from ordinary users. Decision tree (DT) and support vector machine (SVM) are two supervised learning methods among several classification algorithms in ML. Both algorithms are the most popular classification techniques due to their ability to change a complex decision-making process into a simple process. In this study, the accuracy of the DT and SVM algorithms is studied on classifying raisin seeds into the Besni class and the Kecimen class based on existing features. The raisin data are divided into training and testing data, and the evaluation of the two methods is done using the testing data. The results of the evaluation are compared based on the accuracy, sensitivity, specificity, and kappa levels of the DT and SVM algorithms. The results on classifying raisin seeds data show that the SVM algorithm is superior to DT, therefor the number of positive observations is more precise in the prediction.

Authors: Aini Septi Dariyatul , Subaidi Agus , Tafrilyanto Chairul Fajar
Published: May 2023

The low student learning outcomes in the measurement material can be caused by the tendency of teachers to only transfer their knowledge to students' minds so that students are passive, and not critical. One learning approach that pays attention to this situation is a realistic mathematical approach based on Madura local wisdom. Students are presented with contextual problems, namely problems related to measurements, so that they are trained to get used to solving problems in their daily lives. To support this realistic mathematics approach, a clopedimatics-based learning media will be designed as a substitute for textbooks used by students. Clopedimatics is a form of print media that is compiled based on the concept of compiling an Encyclopedia and designed to help students master the measurement material and is associated with non-standard units of measurement used by the Madurese community. This type of research is development research that uses a 4-D model but has been modified to 3-D, namely defining, designing, and developing. The conclusions of this study are development of clopedimatic learning media with a realistic mathematics approach based on Madurese local wisdom in the measurement material at SDN Barkot 1 Pamekasan meets the valid, practical, and effective criteria.

Authors: Ruchkina Marianna
Published: May 2023

The functioning of any industry is impossible without constant development and improvement, which, in turn, leads to the introduction of changes. Effective functioning of any organization is impossible without systematic and long-term development, in which the process of managing organizational changes plays the main role. Some changes directly depend on decisions made in an organization, others are related to decisions made from outside, and completely other decisions are only predicted. All changes that were planned or not planned necessarily have consequences for an educational institution. The purpose of the study is the theoretical justification of the management of an educational institution under conditions of changes, the identification of factors inhibiting the process of their implementation. The research methods used are as follows: analysis, generalization, systematization, questionnaire. It was revealed that the characteristics of change management in educational organizations are: peculiarity of educational change; differences between educational changes; components of the educational process; functions particularity of innovative management of education. The study of educational changes is carried out with the help of special methods, including: the method of groupings, the method of modeling a management system of educational innovations at different levels, the method of ranking, the method of analogy in the field of innovations in education and their management. These types of educational changes have been identified: pedagogical, technical-technological, economic, social, institutional, political-managerial. Factors inhibiting the process of implementing changes in educational institutions were studied, namely: the qualitative and quantitative composition of the teaching staff, the number of participants in the educational process, the desire of the head of an educational institution to implement changes, the level of financial support of an institution. The following factors for the effective implementation of changes in educational institutions have been determined: psychological and financial stimulation of a team, motivation of the head of an educational institution and teachers, visualization of changes, constant monitoring, analysis of the implementation of changes and formation of a collective vision. The reasons that hinder the effectiveness of implementing changes in educational institutions are: lack of experience in implementing changes, low level of competence of the head of change management and inconsistency of changes with the requests of education users, external factors that affect institution's activity as a whole.

The article focuses on the study related to linguocultural competence of future translators of the Chinese language, its structural elements and factors of its development. The concept "competence" has been analysed and clarified within the framework of training future translators of the Chinese language in high school. It has been found out that linguocultural competence is part of the spectrum made of basic competences that should be formed and developed in order to fully achieve academic success. The pedagogical phenomenon "competence" is interpreted as a quality-resultative integrated characteristic of the individual, which is identified at the end of the study through the knowledge, skills and experience accumulated in the process of profession-oriented training and the ability to use them in practical activities. It has been proved that the “criterion” is the key phenomenon of the quality assessment in education system. The author defines the criteria and indicators for assessing the linguocultural competence of students, as well as the levels of this competence proficiency in the Chinese language. The criteria for assessing the linguocultural competence of students is associated with the reflection degree of the object’s properties integrity which ensures its existence; with a criterion for evaluating activity results the content of which is revealed due to certain markers (indicators); with a feature on the basis of which an assessment is made, which is specified in indicators. The structure of the linguocultural competence of future Chinese translators has been determined. The criteria and indicators of the linguocultural competence of future Chinese translators have been presented: cultural-educational competency (with indicators: philosophical-cultural, Confucius-oriented), literary-artistic competency (with indicators: folkloric-ethnographic, lyrical-prosaic), comparative-cultural competency (with indicators: educational-cultural, national-cultural), professional-communicative competency (with indicators: linguistic-communicative, translation- and activity-oriented).

Published: May 2023

Aim. The present study was carried out to evaluate the wound healing potential of crude Hydroalcoholic fruit extracts of Grape (Vitis vinifera L.) and Pomegranate (Punica granatum L.) in experimental animals.

Material and methods. Extracts were formulated as ointments (250 mg), and their wound healing properties were determined by using two models: i.e. excision and burn models, in rabbits. Wound healing potential was assessed by measuring rate of wound contraction (percentage wound contraction) and the epithelialization period. Tukey test (HSD) test was used to analyze the obtained results. The value of p <0.05 was considered as a level of significance. The reference standard was wadded Cicatryl® ointment.

Results. The result showed that crude fruit extracts of Vitis vinifera L. and Punica granatum L. exhibited a significant (p <0.0001) rate of wound contraction and significant (p<0.0001) decrease in the period of epithelialization compared to the control (untreated) group in both the models studied.

Conclusion. Our results suggest that topical treatment of fruit extracts of Vitis vinifera L. and Punica granatum L. accelerate wound healing activity, thus our study supports their traditional use. Both extracts can be used as a potential source of wound healing therapeutics.

Liver damage is a common problem around the world, and pharmacocorrection of such disease is carried out by administration of various drugs. Natural and synthetic thio-containing compounds are important in this respect. Most of these, however, have side effects and do not always meet the criteria of evidence-based medicine. Therefore, the search for new drugs with hepatoprotective properties, characterized by high efficiency and low toxicity, is an urgent problem of current pharmacology and biochemistry. The purpose of this study was to assess the acute toxicity of new potentially bioactive S-substituted pteridinones, to select the least toxic substance, to improve the pharmaco-technological characteristics, and to study the hepatoprotective properties in an experimental model of tetrachloromethane hepatitis in rats. Herein, comparison of the hepatoprotective properties of compound 4.1 and the reference drug "Thiotriazoline" is based on biochemical studies. The research results showed that sub-stance 4.1 had a positive effect on biochemical processes by increasing the compensatory mechanisms of antioxidant systems, while reducing the infiltrative, destructive and inflamma-tory process in the liver, evoking decreases in the cytolytic process, restoring the structure of the components of the membrane of hepatocytes, stabilizing and enhancing the functional activity of the liver, restoring the liver’s protein-synthesizing function and increasing the abil-ity to restore metabolic disorders in the liver. As a result of the biochemical study of the hepa-toprotective effect of compound 4.1, it was found that the studied substance is a non-toxic compound with antioxidant properties.

Published: April 2023

Trafiken är den farligaste miljön för poliser att arbeta i, sett både till antal som förlorar sina liv i tjänsten och skador på både personer och fordon. Därför är förarutbildning en viktig del av polisutbildningen på grundnivå och fortbildningsnivå. Sådan utbildning är dock resurskrävande och vissa förmågor är därför svåra att öva på. För att skapa en effektiv, trygg och säker utbildningsmiljö testades körsimulatorer som del av förarutbildningen vid Polisprogrammet vid Malmö universitet. 83 studenter som genomgick termin två och sedan termin tre deltog i en studie där grupper som fick olika typer av undervisning och sedan samma examination jämfördes för momenten lågfartsmanövrering och landsvägskörning. Resultaten visar att det inte finns några signifikanta skillnader i hur studenterna presterar på praktisk examination beroende på om de tränat i simulator, både simulator och i polisbil eller endast i polisbil. Implikationer av resultaten och framtida forskning diskuteras.

Coal resources are inclusive (reserves are part of the resource), of which 48% is located in South Sumatra, with 70% of the deposits being brown or low-quality coal. With the high amount available, the direct use of coal has several shortcomings, one of which is that coal releases gases (CO2, N2O, NOx, SOx and Hg) which cause global warming. Coal gasification is a process for converting solid coal into a gas mixture that has a fuel value. Coal gasification will yield producer gas in the form of synthetic gas (syngas) with the main components consisting of carbon monoxide (CO), hydrogen (H2), and methane gas (CH4). By converting coal using gasification as a clean energy producer, a blower as a regulator of air flow, a cyclone as a tar separator and a gas cooler. Based on the results of testing the variation of coal used, the variation of 5515 kcal /kg coal has a rapid rise in temperature and is able to produce a flame for 115 minutes. with the composition of Syngas CO and CH4 of 12.4% an 1.2%, while the coal variation of 4640 kcal/kg produces the highest H2 of 6.9%. Coal 5515 kcal/kg produces the largest percentage of syngas conversion, carbon conversion, Low Heating Value, power output and stove efficiency, namely 13.46%, 70.397%, 2.427 MJ/kg, 18.403 kW and 31.23%.

Published: May 2023

The efficacy of public administration strategies has been gauged on how they handle pandemics and the knock-on effects that occur on the environment or society, and in this case, in the rural water supply in Mexico in times of pandemics. Water access in rural Mexico and how the government has managed the rise in demand during pandemics are explored using a systematic review into 51 documents. Mexico’s water system is below par and there is a need for more investments to be pumped into community management schemes. The involvement of the public in the development of community management schemes is necessary to find a solution to the changing demand and supply.
Time to Move On
Authors: Weir Justin
Published: April 2023

The reform of Canada’s federal electoral system was a key platform promise of the Liberal party throughout the 2015 election campaign. Justin Trudeau famously proclaimed that the 2015 federal election would be the last in Canada under a first-past-the-post (FPTP) system; but, as several years followed, there was no change, and discourse surrounding the issue has largely fizzled out (Small, 41). Canada’s FPTP system has not changed since confederation, and it remains among only four other democracies worldwide that use “this archaic electoral system” (Rebick). FPTP is considered to create two main issues in Canadian politics: distortion of votes, and heightened regionalism. Voting behaviour and outcomes are currently distorted through unequal vote weight, ‘wasted votes’, and the phenomenon of strategic voting. Regionalism leads to national division, skews which issues are considered electorally important, negatively alters party behaviour, and changes how political preferences are perceived in Canada. Together, these effects are disengaging the Canadian public from political participation. This paper will explain the ways in which vote distortion and regionalism plague Canada’s current electoral system and the health of its democracy, and demonstrate how a shift towards a mixed-member proportional representation (MMPR) electoral system can alleviate those issues. Specifically, MMPR’s provision of a broader second vote nullifies the effect of wasted votes and strategic voting, while discouraging political parties from engaging in behaviour that targets specific electoral regions and produces political polarization.
Reconciliatory Federalism
Authors: Nohr Liam
Published: April 2023

In 2015, Canada saw a Liberal government form under the young and energetic leadership of Justin Trudeau. After a Conservative government under Stephen Harper, Trudeau set out to bring a ‘fresh and exciting’ vision of Canada that prioritized reconciliation with Indigenous peoples. Thus “reconciliatory federalism” was born. Since then, discussions between Indigenous leaders and the federal government have increased exponentially, yet the undertones of Canada’s colonial history still play an evidentiary role in Canadian federalism. This paper seeks to evaluate Trudeau’s “reconciliatory federalism” in relation to the scholarly literature pertaining to Indigenous self-determination and Canadian federalism. Moreover, using definitions of Kiera Ladner’s treaty federalism and Martin Papillon’s multi-level governance as a theoretical framework, I seek to investigate if Trudeau’s vision of reconciliatory federalism can bridge the two scholarly camps together. While treaty federalism argues for a top-down approach to establish a nation-to-nation relationship between Indigenous peoples and the state, multi-level governance argues for a bottom-up approach in which Indigenous peoples find multiple avenues within the existing federalist structure to integrate into. Using the examples of the Wet’sewet’en Cree First Nation and the Manitoba Métis Federation, I seek to contextualize the implications of reconciliatory federalism in relation to the two scholarly camps.
Myositis-myasthenic overlap syndrome triggered by pembrolizumab in a melanoma patient: a case report and brief review of the literature
Authors: Carrolo Margarida , Machado Sara , Gomes Paulo , Chaves Andreia , Quintela António
Published: May 2023

Background:

In the era of precision medicine, immune checkpoint inhibitors (ICIs) have dramatically changed the therapeutic approach toward advanced cancers. Despite an undeniably therapeutic benefit, ICIs have unique and uncharted toxicities known as immune-related adverse events (irAEs).

Case Presentation:

We report a rare overlap syndrome of inflammatory and necrotizing myopathy with a superimposed myasthenia-like syndrome in a melanoma patient who had received the first dose of pembrolizumab 22 days before symptoms onset. The patient initially presented with muscle weakness and ptosis and rapidly progressed to tetraparesis, extrinsic ophthalmoplegia, dysarthria, dysphagia, and respiratory difficulty with a short-term need for non-invasive ventilation and nasogastric intubation. Transitory myocarditis was also diagnosed. One month after hospital discharge, the patient still exhibits mild dysarthria, dysphagia, and ptosis and needs walking assistance.

Conclusion:

Although rare, neuromuscular irAEs impose a notable burden on morbidity and even mortality. Early recognition of symptoms and prompt intervention are crucial for the management of immunotherapy-related toxicity.
NEUROGENIC BLADDER INDUCED BY CHRONIC ALCOHOL ABUSE: A CASE REPORT
Authors: KELEŞ Hatice , CANVER Burak , BAŞAR Halil , UYSAL TAN Funda
Published: April 2023

Long-term alcohol consumption may produce wide-ranging effects on the autonomic and peripheral nervous systems like almost all body tissues, but the pathogenesis is still under debate. We presented an extremely rare case of autonomic neurogenic bladder with bilateral hydroureteronephrosis in a male patient describing progressive abdominal distension over a year that is most significant in the last 4 months following alcohol withdrawal after a long duration of alcohol abuse. Chronic alcoholism should be considered in the differential diagnosis of a neurogenic bladder, which may be caused by autonomic dysfunction due to chronic alcohol abuse and may be precipitated by alcohol withdrawal.

Possible Worlds of Everyday Aesthetics: The Experiencing Self, Intersubjectivity and Life-World
Authors: Eugen Ratiu Dan
Published: April 2023

This paper investigates the relationship between the subjective-private and intersubjective-public dimensions of the aesthetic experience in everyday life. I claim that our everyday aesthetic life cannot be conceived of as a mere private world in absolute discontinuity to the public world, such as the “artworld” or the “life-world”, since it includes both personal and intersubjective dimensions. Likewise, although the “everyday” should not be thought of as absolutely one and the same for all, it is possible to search for the common features that emerge from the background of its multiple particularities. The intersubjective engagement is an essential element when analyzing the subject experiencing the everyday aesthetically, so we should acknowledge as well the intersubjective nature of a subject’s self-constitution and experience. Against the idea of the overall discontinuous nature of one’s aesthetic experience, in everyday context vs. artworld contexts, it is therefore important to consider everyday aesthetic experience as being both distinct and integrated into the continuous flux of one’s experiences, as well as related to one’s whole life. These claims will be supported by some insights on the experiencing self, supported by practical philosophy (Gadamer), as well as the characteristics of everyday life and life-world highlighted by phenomenology (Husserl, Simmel, Schutz). All these accounts offer powerful lines of argument in defending a consistent conception of the whole experiencing self and the structure of one’s everyday aesthetic life as well as its intersubjective dimension.

For the philosopher Jacques Rancière there is no ‘art’ without a specific identification regime that delimits it, makes it visible and makes it intelligible as such. A regime of art defines the specific ways in which a given epoch conceives of the nature and logic of artistic representation, puts certain practices in relation to specific forms of visibility and modes of intelligibility, specifies the ways in which the artistic expressions take place within society, what their functions are within social life in general and in relation to the other social activities in particular.
In this article we briefly resume the contents of the three fundamental regimes of art: the ethical, the poetic or representative, and the aesthetic taking into account that these regimes are not strictly historical, but rather ‘meta-historical’ categories, because although they may determine and define certain periods of ‘art history’, it is also possible to state that two, or even the three regimes, they can coexist in a specific time like ours, for example. To undertake this approach, we will bear in mind that Rancière's philosophical proposal has both historical and political components that aim to reformulate the traditional way of considering the aesthetic conditions of political experience and the political dimension of aesthetics.

Brand Texts and Meaning in Post-Digital Consumer Culture
Authors: Hackley Chris , Hackley Rungpaka Amy
Published: April 2023

This paper discusses the mechanisms of post-digital consumer cultural meaning-making using advertising as its point of departure. The assumption is that the post-digital is neither an era nor an epoch but a characterisation that reflects a consumer cultural world of digitised content that operates as a default for many consumers, while the analogue world hovers ghost-like, re-asserting itself where digital technologies cannot serve, where and when they cannot be accessed, or when they fail. In this post-digital world, the locus of consumer cultural meaning-making has shifted, from long-form advertising campaigns, to fragmented and polysemous intertexts that circulate kinetically via social media. In other words, the locus of consumer cultural meaning-making has shifted from the primary texts of brand marketing, to secondary or paratexts. Drawing on Gérard Genette’s theory of transtextuality, the paper discusses how this post-digital meaning-making mechanism plays out, for brands, and beyond, within a post-digital consumer culture.

Epistemological Questions for a Speculative Pragmatist
Authors: Van Gemert Ties
Published: April 2023

This essay will engage in a critical dialogue with Massumi’s concept of speculative pragmatism by reconstructing and interrogating the epistemology and metaphysics it presupposes. First, we will narrate and explicate the metaphysics embedded in the philosophy of speculative pragmatism. Secondly, we will recapitulate Massumi’s conceptualization of speculative pragmatism in his book Semblance and Event (2011). Our reading of this book will lead us to argue that speculative pragmatism can be reformulated as a philosophy of panperceptionism. The essay will end with some remarks and questions that aim to challenge the epistemology and metaphysics of speculative pragmatism. We will focus on Massumi’s synthesizing of the subject-object distinction, his theory of judgement, and his deflationary notion of truth.

The Tales of Death and Kindergarten: Becoming in Dark Encounters [COVID-19 Edition]
Authors: Mitranić Nevena
Published: April 2023

For speculative pragmatism, aesthetics is an ethical practice of becoming with the world. Considering educational practice, we might say just the same. But an educational practice is not ethico-aesthetical by its nature – the challenge is to think and live it in an ethico-aesthetical manner. Acceptance of this conclusion goes easily with stressed importance of vitality, movement and creativity of thought – but what about death? Is death even allowed in educational practice? As this paper is written during the emergence of a pandemic, the question goes even further: could education and aesthetics even be of any concern if the danger of death “do us part”? This paper was meant to unfold between memories from an ethnography research in kindergarten and resonate concepts from affect theories – but it exploded unpredictably in resonance with the COVID-19 outburst. Yet, it remained an attempt to tackle the haunting feeling left behind from ‘dark’ encounters with different appearances of death. Hopefully, an encounter with this paper might open a crack in the understanding of educational practice, as well as this moment in history, as a much-needed place for patience and rethinking of the human endeavor as a work of art.

How to Make Your Child Sleep: Designing Rhetorical Experiences
Authors: Newcomb Matthew
Published: April 2023

I might give a variety of logical reasons to help my daughter sleep: being tired from swimming, that a sore leg will feel better, or that she will need lots of energy to play with friends. Consequences can be an argument too, like the loss of a stuffed animal if there are any more non-emergency calls for parents before morning. I might even pull out some sort of shameless (and ineffective) ethos-based plea about being the parent and knowing what is best for her. Rhetorical persuasion is a concatenation of moments and forces that are experienced as a unit – a unit with a persuasive quality to it or that creates new directions for speech and action. Similarly, rhetoric can also be understood as the production or design of those experiences. The design is always partial, as no one can control an experience, but the addition, removal, arrangement, and use of elements for the purpose of creating a particular quality of experience is an important rhetorical act. This design-oriented production of rhetorical experiences is a way of focusing on the human agents within a material rhetoric context that avoids relegating the non-human and the non-linguistic to the background. This paper brings design further into the discussion of rhetoric, adds a design-based angle to new materialism, theorizes rhetoric as an experience, considers John Dewey’s notion of experience and Brian Massumi’s work on affect in light of design and material rhetoric, and (of course) to help parents set up their children for a wonderful night’s rest.   Article received: April 20, 2020; Article accepted: July 1, 2020; Published online: April 15, 2021; Original scholarly paper
Extension of Avant-Garde Practices towards New Media: Possible Theoretical Readings of Documentary Art Film Segunda Vez
Authors: Rajčinovska - Pavleska Natali
Published: April 2023

The subject of this analysis is the 94-minute documentary art film Segunda Vez (Second Time Around, 2018) by contemporary Spanish artist Dora Garcia, whose script consists of six separate sections arranged in an authentic narrative whole. The content of the film material is constructed on the basis of a complex theoretical and practical exploration of archival material and the original writings of the Argentine avant-garde theorist Oscar Masotta who devoted significant work questioning the societal and artistic context of the Happening in the 1960s, as a marginal counterpoint to the avant-garde developments that deviated from the cultural norms of Western civilization. Garcia's work represents a complex intertextual network of historical, literary, and philosophical data that encompasses the sensory aspect of the viewer's perception, creating a coherent film unit in which the author uses the mechanisms of narration to create a conceptual artwork. The main goal of this research is to provide a theoretical basis for analysis through narratology, editing as a conceptual tool, and final reading according to semiotics, in order to interpret artistic language as a possible domain for absorbing the experiences of art in extension.

The Bauhaus Viewed from the Perspective of Jacques Rancière’s Theoretical Concept of the Aesthetic Revolution
Authors: Vujović Aleksandra
Published: April 2023

The philosophical platform of the contemporary French theorist Jacques Rancière is one of the crucial interpretations of the way art is identified and acts in various social and historical conditions. Encompassing the domains of political philosophy, social history, education, and aesthetics, Rancière’s oeuvre is vitally important for recognizing the import of aesthetic experience as vital for anticipating the community of the future as well as for understanding the relationship between art and politics. The initial basis of this text comprises Rancière’s aesthetic conceptions, a constitutive element and axiom of which is the principle of equality, which he uses to illuminate the synthesis of art and social context. The text focuses on analyzing the work and creativity of the Bauhaus as an aesthetic practice from the perspective of the aesthetic revolution, as theorized by Rancière. Using analytical and historical methods, the text shows how the Bauhaus successfully used its intentions and practice to overthrow previously imposed hierarchies and conventions of art and, by analogy, social divisions as well, and became a major outcome of the aesthetic revolution as theorized by Rancière.
