Context

Pheochromocytomas and paragangliomas (PPGLs) are neuroendocrine tumors explained by germline or somatic mutations in about 70% of cases. Patients with SDHB mutations are at high risk of developing metastatic disease, yet no reliable tumor biomarkers are available to predict tumor aggressiveness.

Objective

We aimed at identifying long noncoding RNAs (lncRNAs) specific for PPGL molecular groups and metastatic progression.

Design and Methods

To analyze the expression of lncRNAs, we used a mining approach of transcriptome data from a well-characterized series of 187 tumor tissues. Clustering consensus analysis was performed to determine a lncRNA-based classification, and informative transcripts were validated in an independent series of 51 PPGLs. The expression of metastasis-related lncRNAs was confirmed by RT-qPCR. Receiver operating characteristic (ROC) curve analysis was used to estimate the predictive accuracy of potential markers.

Main Outcome Measure

Univariate/multivariate and metastasis-free survival (MFS) analyses were carried out for the assessment of risk factors and clinical outcomes.

Results

Four lncRNA-based subtypes strongly correlated with mRNA expression clusters (chi-square P-values from 1.38 × 10–32 to 1.07 × 10–67). We identified one putative lncRNA (GenBank: BC063866) that accurately discriminates metastatic from benign tumors in patients with SDHx mutations (area under the curve 0.95; P = 4.59 × 10–05). Moreover, this transcript appeared as an independent risk factor associated with poor clinical outcome of SDHx carriers (log-rank test P = 2.29 × 10–05).

Conclusion

Our findings extend the spectrum of transcriptional dysregulations in PPGL to lncRNAs and provide a novel biomarker that could be useful to identify potentially metastatic tumors in patients carrying SDHx mutations.

Published: November 2019

Our environment is filled with chemicals that pollute the air, water, soil and food, the need to find solutions to the pollution problem. In this study, owing to the research niches like waste beneficiation, macadamia nutshell activated carbon (MAC) was investigated for its potential usage as an adsorbent for chlorinated phenols: 3-chlorophenol, 2,4,6-Trichlorophenol, 4-chloro-3-methylphenol, 2,4-Dichlorophenol removal, and its activity compared with grafted macadamia nutshell activated carbon (GMAC). The adsorbent was characterized using FTIR, SEM, and TGA. Parameters like pH, temperature, contact time, concentration and adsorbent were examined. The PFO and PSO kinetic models were employed to investigate the experimental data. The PSO displayed the best fitting for the kinetic studies for MAC adsorption. The kinetics studies confirmed the adsorption system by pseudo-second-order kinetics model. The negative values of ΔG confirmed a spontaneous process, thereby, supporting the physisorption mechanisms of interactions between the chlorinated phenols and the adsorbents

Published: November 2019

Halda River (HR), the lone natural carp breeding ground in Bangladesh as well as in Southeast Asia is an economically important river and its water quality is deteriorating due to unplanned industrialization and various anthropogenic activities. The present research work has been conducted to assess the characteristics of HR water. Eighteen water quality parameters were studied including pH, temperature, Dissolved Oxygen (DO), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Dissolved Solids, Electrical Conductivity, Hardness, Turbidity, Total Alkalinity, SO42-, PO43-, NO3-, Cl-, NH4+, Cr (VI), Mn (II) and Arsenic. This study shows that water in HR is regularly alkaline and its pH lies between 7.08-7.65. The DO value varies from 5.9-8.4 mgL-1, BOD ranged from 0.3-2.8 mgL-1 and COD from 24-96 mgL-1. According to the Water Quality Index study, the river is being intensely polluted due to the unscrupulous industrial wastes discharge into the HR through various canals.
Complex of Tris(Phenanthroline)Cobalt(II)Trifluoroacetate: Characterisation and Powder XRD Analysis
Authors: Louise Isana Supiah Yosephine , Nabila Savetsilla , Sugiyarto Kristian Handoyo
Published: November 2019

The powder complex of tris(phenanthroline)cobalt(II) trifluoroacetate (TFA) has been prepared by interaction of cobalt(II) nitrate, phenanthroline (phen) in aqueous solution with drops of ethanol, and an excess of saturated aqueous solution of sodium trifluoroacetate, whereupon the yellowish powder was produced. AAS measurment for the metal content, equivalent conductance (1:2), and TGA-DTA of the powder suggest the corresponding formula of [Co(phen)3](TFA)2.5H2O. The efffective magnetic moment of 4.9 BM indicates the high-spin nature of this complex which corresponds to three unpaired electrons in the electronic configuration of Co(II) with significantly higher than the spin only value due to the orbital contribution. UV-Vis spectrum of the complex reveals the d-d spin-allowed transition bands as well as the MLCT and intraligand band. The estimating transition energy ratio of 2.04 for ν2/ν1, is clearly in the range for octahedral configuration. The infrared spectral property indicates the main mode of vibrations for the functional groups of ligand phen and TFA, and thus supports strongly the formula proposed for this complex. The corresponding powder XRD was then refined using Rietica-Le Bail method and found to be fit as triclinic crystal system with space group of PĪ.
Effect of Modified Kiln Dust and a Cationic Surfactant on the Removal of Aromatic and Heavy Metal Compounds from Fuels
Authors: Mehbad Noura Yahya El
Published: November 2019

This paper aims to investigate removal of aromatic and heavy metals compounds from fuels using cement kiln dust, and a cationic surfactant. The effect of a cationic surfactant and the composition of kiln dust on the stability of fuel was studied. The optimum conditions of adsorption were investigated. The stability of fuels was improved after adsorption because of the absorption of heavy metals, which act as catalysts. The concentrations of kiln dust and additives are effective for the absorption of heteroatoms of polar and nonpolar molecules. The addition of different concentrations of the cationic surfactant to kiln dust enhances the removal of polar molecules in fuel. The relation between the efficiency of the cationic surfactant and the enhanced removal of polar molecules was established. This study suggests a new mechanism to remove polar molecules according to the structure of the additive. Several parameters that affect the performance of the removal process were investigated under all optimum conditions. A complete chemical analysis of the fuels before and after treatment was performed, and the stability of the fuel was evaluated at different conditions. The prepared additive could enhance the oil quality and is environmentally safe. The adsorption behaviour of kiln dust was investigated to find a new mechanism of its efficiency. The results confirm the role of the cationic surfactant in the purification of fuels and the effectiveness of kiln dust in improving the stability of fuels, which depend on the concentration of the cationic surfactant and the nature of the kiln dust.

The montmorillonite (MMT) nanoparticles as patchouli oil bleaching has been prepared from the isolated MMT of Aceh Tamiang bentonite. MMT in bentonite powder was isolated through a top-down isolation method by ultrasonication, sedimentation and high energy milling process. As many as 14% of MMT was successfully isolated and characterized via XRF and XRD. XRF analysis on the composition of isolated MMT indicated that the major composition of MMT are Si (24.76%) and Al (16.37%). From XRD pattern, the two theta (2θ) peak of MMT are about 19.85°, 20.30° , 26.62 and 50.15° that was identified as MMT (empirical formula (Si7.80Al1.72Cs0.16Fe0.20Mg0.28O20.00)), indicating the success of the isolation process. Furthermore, based on the results calculated using XRD with Scherer’s equation, the size of MMT was 0.42 nm and the derived lattice constant was 4.20 Å. Moreover, the MMT nanoparticles exhibited as a good Patchouli Oil Bleaching material to reduce colors in oil.

Authors: A Haydar , Salim Mohammad- , Abdallah Hassan H
Published: November 2019

This study presents the intramolecular [2+2] cycloaddition reaction of ketenes to form cyclobutanones using B3LYP-D3/6-311++G(d,p) level of approximation. The concerted mechanism path was studied in detail. The structures of all intermediates and transition states were located using same level of theory. The influences of the substituents (-H, -CH3, -NH2, -F, -OH and –CN) were also discussed. The analysis of stationary points and the energetic parameters indicates that the substituted ketene with –CN group has the highest activation energy; however, ketene with –NH2 group has the lowest one. Conversely, in-tramolecular [2+2] cycloaddition records the highest degree of asynchronicity with –NH2 group and lowest with –CN group. The calculated thermodynamic parameters at room temperature have been listed and analyzed. The global and local properties of reactants involved in the intramolecular [2+2] cycloaddition reactions and the Fukui functions for an electrophilicity and local electrophilicity were also elucidated for carbon centers of each reactant.
Evaluation of Wheat Bran as a Biosorbent for Potential Mitigation of Dye Pollution in Industrial Waste Waters
Authors: Das Sujata , Singh Shalini , Garg Shashank
Published: November 2019

Crystal Violet (CV) is a basic dye that is extensively used for various industrial uses, ranging from, antimicrobial agent, paints, printing ink, biological stains, to textile dyes. Despite its many uses, it has been associated with environment pollution and toxicity, just like other chemical based industrial dyes, if not kept in check. In the current study, wheat bran (WB), an agro-industrial waste reside, was tested for its adsorptive potential for removal/decrease of CV from industrial waste waters. Under optimized conditions of incubation (pH 8, temperature 30° C, adsorbent concentration 10gm/L, time 180 mins & adsorbate concentration 100mg/L), the adsorbent removed around 88% of CV from its aqueous solution, fitting appropriately adsorption model (Langmuir isotherm) with maximum adsorption capability (qm) value of 25.66 mg/gm, and following pseudo first-order kinetic model. Alkali treatment of adsorbent, though, showed around 4% increase in dye decolorization, but unmodified bran was preferred for further work to justify the need for cheap and environment friendly adsorbent to remediate industrial dye waste waters.

The aim of this study was to identify the chemical structure of anthocyanins in the fruits of Ficus Aurata. The anthocyanin was detected and characterized using the liquid chromatography system with UV-VIS detection tandem triple quadrupole mass spectrometer. After UV-VIS detection, the characterization of anthocyanin was subjected to a triple quadrupole system of mass spectrometer. The precursor ions of anthocyanidins (cyanidin, delphinidin, malvidin, pelargonidin, petunidin, and peonidin) were scanned to identify the distinctive particular anthocyanin. Then, the detected anthocyanins was further confirmed and their isomers such as glycosides and galactosides forms were distinguished by the fragmentation pattern on product-ion analysis scan after comparison with mass spectroscopy online databases. For the first time, it had characterized that in the fruits of Ficus Aurata contains at least seven kinds of anthocyanins with all possible combinations of three anthocyanidins.

Authors: Khanna Charu , Singh Shalini , Vyas Manish , Das Sujata
Published: November 2019

The efforts for prevention of food borne illness and infections draw great attention, worldwide. Different methods, both physical as well as chemical, are commonly used for improving shelf life of food, but limited efficiency of physical methods, and potential health hazards associated with chemical methods, have brought biological processes in the limelight. One such natural, environment friendly, highly effective natural food preservants are, bacteriocins. Thus, there is a continuous need for better bacteriocin producers in the search for more effective bacteriocins than what are already available in the market. In the current study, food samples were collected from local market of Jalandhar, Punjab, and evaluated for bacteriocin producing Lactic acid bacteria. Enterococcus sp. YT3 was found to be the most efficient bacteriocin producer among the isolates, with higher bacteriocin activity exhibited by the given strain under optimized cultural conditions. The partially purified bacteriocin have molecular weight between 35kDa & 48kDa, possess pH (2-10) and thermal stability (even at 121o C for 20 minutes), and exhibit biological potential against different bacteria (E. coli, P. aeruginosa, L. monocytogenes, S. aureus and B. subtilis). Future studies will focus on checking different food samples for real time evaluation of shelf life improvement.
Solvent Free Green Protocol for the Synthesis of Anti-Bacterial Schiff Base Dimers
Authors: Meenakshisundaram Sangeetha , Manickam Manoj
Published: November 2019

A novel series of Schiff base dimers have been designed and synthesized from phthalaldehydes and various amines including aliphatic, aromatic and heterocycles by grinding at room temperature. This solvent free green protocol approach is superior to the classical approach which uses ethanol as solvent. The advantage of this new method is that wide substrates can be incorporated, very simple to carry out the reaction, easy workup with high product yield. Compounds obtained have been screened for anti-bacterial activity against nine different strains (six Gram-negative and three Gram-positive) which include E.coli, Proteus mirabilis, Klebsiella pneumonia, Proteus vulgaris, Morganella morgana, Salmonella typhi, Staphylococcus aureus, Methicillin-resistant Staphylococcus aureus, Enterococci faecalis. Among them, the heterocyclic groups in the side chain of the Schiff base showed better activity than the aromatic and aliphatic groups. Particularly the thiophene substituted 1,4-isomer of the Schiff base dimer showed good antibacterial activity against seven strains. Interestingly, the 1,3 isomer of the Schiff base dimer with thiophene substituent exhibited a potent antibacterial activity. An effective Structure-Activity Relationship have also been established for the Schiff base dimers to find novel and potent anti-bacterial agents.
Social work as revolutionary praxis? The contribution to critical practice of Cornelius Castoriadis’s political philosophy
Authors: Ablett Phillip , Morley Christine
Published: November 2019

Social work is a contested tradition, torn between the demands of social governance and autonomy. Today, this struggle is reflected in the division between the dominant, neoliberal agenda of service provision and the resistance offered by various critical perspectives employed by disparate groups of practitioners serving diverse communities. Critical social work challenges oppressive conditions and discourses, in addition to addressing their consequences in individuals’ lives. However, very few recent critical theorists informing critical social work have advocated revolution. A challenging exception can be found in the work of Cornelius Castoriadis (1922–97), whose explication of ontological underdetermination and creation evades the pitfalls of both structural determinism and post-structural relativism, enabling an understanding of society as the contested creation of collective imaginaries in action and a politics of radical transformation. On this basis, we argue that Castoriadis’s radical-democratic revisioning of revolutionary praxis can help in reimagining critical social work’s emancipatory potential.
Territoriality and ancestral governance: the case of the Puel Nahuelbuta Mapuche Indigenous Development Area of Chile
Authors: Calbucura Jorge , Almonacid Milton
Published: November 2019

The main objective of this article is to introduce the case of the Puel Nahuelbuta Indigenous Development Area (Mapuche, Chile) as a design practice that fosters local autonomy and, at the same time, contributes to the debate on radical alternative imaginaries towards post-patriarchal and post-capitalist social and cultural relations. In this context, the Az Mapu (knowledge of the natural order of the territory) rationality is important as a concept in the right way round indigenous territory and its governance. A second factor that stabilises the design practice of local autonomy is Kimün (ancestral philosophy or wisdom). Ixtrofil Mogen (living in biodiversity) and Küme Mogen (living well/good living), being the ability to reflect according to the experiences, knowledge and circumstances faced by a person or group, are central. The questioning of these notions highlights the controversy between social justice, indigenous social work and indigenous traditional knowledge.
Queering the stitch: Fashion, masculinity and the postsocialist subject
Authors: Roberts Graham H.
Published: November 2019

In my article, I analyse some of the ways in which Gosha Rubchinskiy, Demna Gvasalia and Lotta Volkova might be said to ‘queer’ masculinity. I draw parallels between their work and the modernist, utopian, Constructivist project of Soviet fashion designers of the 1920s such as Varvara Stepanova and Lyubov’ Popova. Most importantly, both groups of artists share a desire to organize their fashion practice within a broader ideological project. At the heart of their respective projects is a fundamental challenge to conventional notions of gender in fashion, and in the fashion industry. In both cases, the ‘queering’ of gender norms, distinctions and hierarchies, both on and off the catwalk, is designed to produce a radical transformation of the relationship between the fashioned object and the fashionable, consuming subject. As far as today’s post-Soviet fashion designers are concerned, by the way in which they either queer masculinity or perform their own, queer brand of masculinity, they produce a new, utopian subject. Far from being the antithesis of the Constructivist project, then, this post-socialist utopian body can be seen as constituting perhaps its most spectacular realization to date.
Gen-Y men and ‘Fast Fashion’: Who values it?
Authors: Sung Jihyun , Woo Hongjoo
Published: November 2019

Fast fashion refers to the clothing that follows the latest fashion trends at affordable prices. Although fast fashion could cause environmental, social and ethical issues, it has been widely consumed by young consumers because of its various styles with inexpensive prices. Thus, the current study investigated how Gen-Y males’ varied decision-making styles influence their perceptions towards fast fashion differently. The results of an online survey collected from 335 Gen-Y males showed that there are two different decision-making groups: indifferent realists and conscious fashionistas, which were dissimilar in their ethnic distribution. Further, their varied decision-making dimensions influenced their perceptions towards fast fashion differently. These results contribute towards the existing literature related to fast fashion and provide insightful perceptions for fast fashion marketers in targeting Gen-Y male consumers.

Nordic noir vs. spies in the cold: The reception of Scandinavian TV and film adaptations in Germany
Authors: Hindersmann Jost
Published: November 2019

Scandinavian crime novels and their adaptations as TV dramas and films, commonly known as Nordic noir, are very popular in Germany. Nordic noir often has a political content and when spies appear, they are usually portrayed negatively. Scandinavian spy novels and their adaptations, on the other hand – with the exception of Guillou’s Coq Rouge series – never reached wide audiences in Germany.
M.I.A.: Actors, acting and Swedish superspy Carl Hamilton
Authors: Holmlund Chris
Published: November 2019

Carl Gustaf Gilbert Hamilton is the best-known of Swedish fictional spies – in Scandinavia at least. The brain child of novelist Jan Guillou, Hamilton is Sweden’s James Bond or Dirty Harry. Five prominent Swedish actors – Stellan Skarsgård, Peter Haber, Stefan Sauk, Peter Stormare and Mikael Persbrandt – have played the spy on-screen, yet unlike Sean Connery and Daniel Craig as Bond or Clint Eastwood as Harry, their performances have been largely unnoticed, even in Sweden. This article studies their acting with two goals in mind: (1) to show how actors have shaped Sweden’s best-known secret agent on film and for TV, and (2) to elucidate how their acting decisions respond to genre customs and constraints. In conclusion I comment on why the screen Hamiltons have not found audiences outside Scandinavia and indicate ways that transnational action genres have helped reshape Swedish culture, transforming one of its national icons, Hamilton, in the process.
Stereotyping Scandinavia in popular spy films: The image of the female
Authors: Stankevičiūtė Kristina
Published: November 2019

Stereotyping, though considered ‘politically incorrect’, is viewed by some as a culturally economical choice that helps us save energy by simplifying the process of perceiving the world and its people. Spy films, in turn, are often constructed from certain clichés that some viewers expect, while more sophisticated spectators find them discrediting. Yet intentional use of clichés, including national and cultural stereotypes, may serve the purpose of conscious criticism or cultural irony, as is often the case in spy film parodies or spoofs. Referring to the widespread spy narrative character typology embodied in James Bond films, the article considers the popular stereotype of the Scandinavian woman observed in twenty-first-century espionage films for wide audiences, focusing on the Hamilton and Kingsman series to examine the effects that serious or ironic use of the stereotype has on the representation of female characters.
A Casablanca of the North? Stockholm as imagined transnational setting in the British spy thriller Dark Journey
Authors: Hochscherf Tobias
Published: November 2019

The article examines the largely forgotten British émigré film Dark Journey, its Swedish setting and Scandinavian release. The spy drama, which tells the story of German and French secret agents in Stockholm during World War I by mixing thriller elements with romance, raises a number of questions regarding the representation of spies in a Scandinavian context, Sweden as a contested film market in the later 1930s and the transnational production strategy of films made at the Denham studios in Britain. It is one of the films that helped the profession of secret agents to change its image from a dingy and unchivalrous activity to an adventurous, illustrious and cosmopolitan enterprise. Interestingly, the film offers a very positive portrayal of its German protagonist, played by Conrad Veidt, that is at odds with other Anglo-American spy films but not at all uncommon for Swedish spy fiction.
German surveillance of the Swedish film market during World War II
Authors: Stjernholm Emil
Published: November 2019

This article approaches the subject of German film policy in Sweden during World War II from a new perspective. While several film scholars have mapped the connections between the German and Swedish film industries in the past, less is known about the German surveillance of Swedish film criticism, Swedish cinema audiences and Allied newsreel competitors. Drawing on previously overlooked archival material from the German film company Ufa’s Swedish subsidiary, digital newspaper archives and previous research on German film strategies abroad, this article offers new insights into the ways Ufa monitored the film market in neutral Sweden.
“Todo mundo quer ser perfeito mesmo” Significados da vivência escolar e reforço para uma adolescente
Authors: Rodrigues Marina Lara
Published: November 2019

Neste trabalho são apresentados e analisados alguns dos significados de uma estudante do ensino fundamental para a experiência escolar vivenciada, a partir de uma demanda de reforço escolar realizado pela aluna. Esta atividade é parte constante da vida diária de muitas crianças e adolescentes no Brasil, e observa-se que pode ter conotações tanto positivas (quando auxilia o jovem em um processo de descoberta e desenvolvimento) quanto negativas (quando se torna uma forma de estigma e exclusão) para a vida dos estudantes, enquadrando e dando novos significados à experiência escolar de uma forma geral. Para o levantamento de dados foi realizada uma entrevista semiestruturada com uma adolescente de 10 anos, com posterior transcrição e análise dos dados utilizando o método da Análise de Conteúdo de Bardin (2016). A análise é complementada com o apoio de autores e teorias das áreas de Educação e Psicologia. Os resultados e a conclusão sugerem que professores, pais e profissionais da educação precisam de subsídios para ressignificar o reforço escolar e sua relação com a experiência escolar como um todo, transmitindo por sua vez, uma imagem mais positiva desse processo aos jovens e adolescentes, para que seja considerado como uma oportunidade de desenvolvimento ao invés de ser visto como forma de punição ou causa de exclusão.
Introduction: Haunting in the Land of the Untraumatized
Authors: Dziuban Zuzanna
Published: November 2019

The introduction interpretively explores the »spectral turn« unfolding in the Polish post-Holocaust imaginaire: it examines the emergence and proliferation of the figure of the Jewish ghost across the realms of cultural production, art, popular imaginings, and academic culture, and provides a frame for the contributions collected in the volume. Establishing the aesthetic and affective politics of the ghostly as a subject of multiperspective and multidisciplinary inquiry, it asks about the position of Jewish ghosts in shifting cultural attitudes towards the Holocaust and the »Polish-Jewish past« and present. Attentive to a particular type of ghost, the Jewish ghost in post-Holocaust Poland, it argues that ghosts are dense social and political figures. Moreover, this introduction is organized so as to reflect shifting trajectories in the production of, and interpretive involvement with, Jewish ghosts in Poland: from engagements with the representational, aesthetic, and affective politics of ghosts to their particular political positioning; from readings locating ghosts in the broader horizon of Holocaust art, literature, and theory to theorizations developed from within the empirical and material reality of haunting. This organization works along a specific analytical directionality - towards an understanding of ghosts that disentangles them from questions of memory and trauma and entangles them directly with questions of order, power, and hegemony.
Konstellationen von Körper, Medien und Selbst
Authors: Rode Daniel , Stern Martin
Published: November 2019

Der einleitende Beitrag diskutiert die Programmatik eines »Denkens in Konstellationen« als einen Fluchtpunkt für Ansätze, die Phänomene wie Self-Tracking, Selfies und Tinder betrachten und sich dabei kritisch mit Konzepten von »Körper«, »Medien« und »Selbst« auseinandersetzen. Die Ausgangsthese ist, dass diese Phänomene zeitgenössische Räume darstellen, in denen sich die Teilnehmer*innen spielerisch ins Spiel einer sich wandelnden Gesellschaft bringen. In einem ersten Schritt wird diese These ausgeführt. Daran knüpft im zweiten Schritt die Spezifikation der Perspektive des angesprochenen »Denkens in Konstellationen« an, mit der im dritten Schritt Konsequenzen für und kritische Nachfragen an »Körper«, »Medien« und »Selbst« formuliert werden. Der Beitrag schließt mit einem Überblick über die Struktur des Buches.
Körper - Medien - Selbst in neuen Sportpraktiken
Authors: Stern Martin
Published: November 2019

Der Beitrag diskutiert den Medieneinsatz in zeitgenössischen, informellen Bewegungskulturen als konstitutiven Bestandteil dieser Spiel- und Sportpraktiken. An Beispielen aus dem Trendsport zeigt er, wie die Teilnehmer*innen als Akteur*innen, Zuschauer*innen und Medienproduzent*innen in Personalunion auftreten und wie die medialen Perspektivierungen der Bewegungspraxis in die Ausgestaltung und Formierung von Idealvorstellungen (ideelle Bewegungsbilder) sowie die Bewegungsbearbeitung bis in die mikro-gestischen Details der Körper- und Bewegungsorganisation hineinwirken. Diese ästhetische Bearbeitung sportlicher Bewegungen und ihre sozial-räumliche Ausweitung auf alltägliche Kontexte werden schließlich als eine Arbeit am Selbst gedeutet.
Selbst-Bildung im und durch Self-Tracking
Authors: Rode Daniel
Published: November 2019

Der Beitrag folgt der These, dass Praktiken der Selbstvermessung als »Spielräume« betrachtet werden können, in denen sich Menschen spielerisch ins Spiel einer sich wandelnden Gesellschaft bringen. Um diese Prozesse auf systematische Weise subjektivierungsanalytisch untersuchen zu können, entwickelt der Beitrag ein integratives, praxistheoretisches Analysemodell. Dieses erlaubt es, bestehende Befunde einzuordnen und weitere Forschung anzuleiten. In einem ersten Schritt wird der subjektivierungsanalytische Zugang ausgehend von einer Heuristik des Spiels konturiert. Im zweiten Schritt wird dieser Zugang in das angesprochene Analysemodell einer Subjektivierung im und durch Self-Tracking überführt und die einzelnen Kategorien des Modells werden näher erläutert. Der Beitrag schließt mit einem kurzen Fazit zu Digitaler Selbstvermessung als Ort zeitgenössischer Selbst-Bildungsdynamiken.

Sie sensibilisiert auch dafür, die Aneignung von und den Umgang mit gesellschaftlichen Körperbildern in deren Brüchigkeit, Unbestimmtheit und Unsicherheit ernst zu nehmen, und akzentuiert das darin enthaltene Potential zur Veränderung und Subversion.
Zur Rekonstruktion kollektiver Orientierungen in Bezug auf Körper, Medien und Selbst
Authors: Zander Benjamin
Published: November 2019

Im Beitrag wird aus einem Forschungsprojekt berichtet, das sport- und körperbezogene Orientierungen von Jugendlichen über den Einsatz eines erweiterten Gruppendiskussionsverfahrens untersucht. Anders als beim Einsatz von ausschließlich verbal ausgerichteten Erhebungsverfahren erstellen die befragten Jugendlichen im Rahmen der Gruppendiskussion auch gemeinsam eine Collage aus Zeitschriftenfotos und ein Gruppen-Selfie. Diese Erweiterungen werden im vorliegenden Beitrag methodologisch begründet und als ein dreiteiliger Gruppenwerkprozess (Diskussion, Collage, Selfie) beschrieben. Anhand zweier ausgewählter Fallbeispiele stehen methodische Überlegungen zur Durchführung und Auswertung (in Anlehnung an die Dokumentarische Methode) des Gruppenwerkprozesses im Mittelpunkt. In diesem Zusammenhang sollen durch die Auswahl des empirischen Materials im Rückgriff auf eine wissenssoziologische Perspektive kollektive Orientierungen in Bezug auf Körper, Medien und Selbst und ihre Konstellationen untersucht werden.
»Geben Sie Gedankenfreiheit!« Verbindlichkeit und Freiheit (in) der Literatur
Authors: Neuhaus Stefan
Published: November 2019

Wenn wir mit Christian Bermes von Verbindlichkeit als einer schwachen Normativität ausgehen, dann müssen wir zunächst nach dem Verhältnis von Verbindlichkeit und Normen fragen. Dass Normen nicht verbindlich sein müssen, scheint ein paradoxer Gedanke, und in der Tat beginnt die Geschichte einer schwachen Normativität im deutschsprachigen Raum erst mit der Moderne im 18. Jahrhundert. In der Postmoderne, der »liquid modernity« (Zygmunt Bauman), werden dann auch noch die übrigen Normen »verflüssigt«, die unhinterfragte Geltung beanspruchten. Alle Normen kommen, zumindest in unserem Kulturkreis, auf den Prüfstand, und der Ausdifferenzierungsprozess der westeuropäischen Gesellschaften beginnt. Die neuere deutschsprachige Literatur entsteht parallel dazu, und sie fördert die skizzierte Entwicklung, indem sie sich für eine moderne und später postmoderne Auffassung von Verbindlichkeit einsetzt oder sie im Medium der Literatur überhaupt erst erschafft. Fiktive Handlungen um Figuren wie Götz von Berlichingen, Marquis Posa oder Wilhelm Tell stellen in der Deutung durch die Leser*innen Wahlmöglichkeiten bereit und zeigen damit die Potenziale einer schwachen Normativität auch für die Realität. Das ist das utopische Potential der Literatur.
Der Auftritt in der Rechtswissenschaft
Authors: Rakebrand Johanna
Published: November 2019

Nach einer Anekdote zu Beginn (A.) gelangt der Aufsatz von der Fragestellung, was ein Rechtswissenschaftler tun müsse, um als Rechtswissenschaftler zu gelten, in bester wissenschaftlicher Manier zur Problematisierung eben dieser Fragestellung, wer überhaupt Rechtswissenschaftler sei und was unter Performanz zu verstehen sei (B.). Nach sorgsam absichernden Hinweisen zum Forschungsstand (C.) erlangt der Leser schließlich Einblick in den Raum »Hinter die Bühne«, d.h. in die juristische Ausbildung und Sozialisation (D.). Unter (E.) schließlich findet der Leser eine informierte Spekulation zum »Auftritt in der Rechtswissenschaft«, die Sprache, Gestik, Mimik, Homepage, Witz, Kleidung und den bildungsbürgerlichen Kanon der Rechtswissenschaftler betrachtet und interpretiert.
Requisit und Symbol wissenschaftlichen Auftritts
Authors: Janecke Christian
Published: November 2019

Wie zum Theater die Bühne und Requisiten, gehört zum Auftritt der Wissenschaft das Rednerpult. Es schützt den Vortragenden vor Blicken auf unerwünschte Partien; es erhöht und exponiert ihn qua Anlage und Stellung im Raum. Der Vorlesung wird es zum Streitwagen ohne Räder - und zur zivilisierenden, da voreiliger Verbrüderung aller Anwesenden wehrenden Mittelbarkeit. Doch in dem Maße, als der Veranstaltungstyp »Vorlesung« unter Beschuss geriet, begann man auch Hörsäle »niederschwelliger« einzurichten. Infolgedessen entschärfte man auch die Rednerpulte zu Multifunktionsmöbeln für Powerpoint-Präsentationen, oder man ebnete sie ein zu Flachpodien. Diese betrübliche Entwicklung ist aufschlussreich als Gradmesser einer Enttheatralisierung und mithin Verarmung wissenschaftlichen Sprechens überhaupt.
Theatralität der Existenz
Authors: Ralfs Sarah
Published: November 2019

Entlang Christoph Schlingensiefs künstlerischer Auseinandersetzung mit Leben und Sterben erforscht Sarah Ralfs die Genealogien des Theaters, der Oper, des Films, der bildenden Kunst und der Installation in seinem Werk. Im Fokus stehen hierbei die kunsthistorischen Bezüge sowie die strukturellen und diskursgeschichtlichen Analogien zu Leben und Tod. Damit wird eine der außergewöhnlichsten künstlerischen Positionen am Beginn des 21. Jahrhunderts in den Blick genommen und nach deren historischer Verankerung gefragt, deren Gegenwartsbezüge diskutiert sowie Visionen einer ästhetischen Erfahrung des Miteinanderseins im Theater der Existenz beleuchtet.
Alleinerziehende Mutterschaft
Authors: Kasten Anna
Published: November 2019

Alleinerziehend sind nach wie vor hauptsächlich die Mütter, die - zumindest im Kontext des Rechts - als auf die Geldzahlungen der Kindesväter Wartende konstruiert werden. Wie genau denkt das Recht also diese Form der Mutterschaft und welches Familienbild liegt hier zugrunde? Um diesen Fragen nachzugehen, betrachtet Anna Kastens transdisziplinäre Studie die Mitwirkung der alleinerziehenden Mütter bei der Feststellung der Vaterschaft im Unterhaltsvorschussgesetz in Deutschland und im Gesetz über Familienleistungen in Polen. Alleinerziehende Mutterschaft erweist sich hierbei als Technologie einer heteronormativen Familienordnung.
Multikulturalismus im Diskurs
Authors: Boldt Thea D.
Published: November 2019

Die deutsche Identitätspolitik hat durch die Auseinandersetzung mit muslimischen Migranten eine neue Wendung erlangt. Thea D. Boldt analysiert diesen Übergang im Zeitraum von 2000 bis 2011 mit besonderem Fokus auf das Konzept des Multikulturalismus. Dabei zeichnet sie die Transformation Deutschlands von einer Nation des ius sanguinis zu einer multikulturellen Gesellschaft in einem diskursiven Spannungsfeld zwischen staatlichen und nicht-staatlichen Akteuren - darunter Vertreter muslimischer Verbände - nach. Vor diesem Hintergrund erscheint die deutsche Debatte um den »Multikulti«-Begriff als Vorreiter einer neuen europäischen Identität und einer neuen europäischen Migrationsagenda.
Die Regierung der Elternzeit
Authors: Neumann Benjamin
Published: November 2019

Mehr Kinder, mehr Arbeit, mehr Wirtschaftswachstum? Die Novellierung des Bundeselterngeld- und Elternzeitgesetzes 2007 gilt als wichtige familienpolitische Zäsur: Mehr Erwerbsanreize, eine verkürzte Bezugsdauer des Elterngeldes und »Partnermonate« stellten wichtige Veränderungen dar. Mit den Familienberichten der Bundesregierung und Interviewmaterial einer Studie zu Vätern in Elternzeit fragt Benjamin Neumann mit geschlechtertheoretisch-gouvernementalem Blick nach Verschiebungen familienpolitischer Rationalität und damit verbundenen Subjektivationsprozessen. Dabei wird deutlich, wie Vereinbarkeitsdiskurse bis in die elterlichen Selbstverhältnisse hineinreichen.
Das Humboldt Lab
Authors: Di Blasi Johanna
Published: November 2019

Das Humboldt Lab Dahlem (2012-2015) gilt als die »Probebühne« des Berliner Humboldt Forums. Transdisziplinäre Teams entwickelten hier innovative Präsentations- und Vermittlungsmodelle für ethnografische Sammlungen. Zeitgleich begann ein großer Szenografie-Dienstleister mit der Gestaltung der Museumsflächen nach dem Muster erlebnisorientierter Themenparks. Daraus erwachsen Fragen zur mehrdeutigen Rolle des Lab im Gestaltungsprozess des Humboldt Forums und der Einbeziehung zeitgenössischer Künstler als »Agents of Change«. Johanna Di Blasi beleuchtet Folgen der wenig beachteten Tatsache, dass kolonial geprägte Museen und ihre wissenschaftlichen Kuratoren von zwei Seiten unter Druck geraten sind: durch die Notwendigkeit postkolonialer Revisionen und durch den Machtzuwachs der Szenografie- und Marketingdomäne.
Pina Bausch und das Tanztheater
Authors: Klein Gabriele
Published: November 2019

Gabriele Klein präsentiert eine neue Sichtweise auf die Arbeit des Tanztheaters Wuppertal: Die Entwicklung und Aufführung der Stücke, die Weitergabe von choreografischem Material und die Reaktionen der Öffentlichkeit werden als komplexe, voneinander abhängige und wechselseitige Übersetzungsprozesse dargestellt. Das Buch rückt zum ersten Mal die künstlerische Forschung vor allem bei den internationalen Koproduktionen des weltweit bekannten Ensembles in den Fokus und bietet umfangreiches empirisches Material in Form von Interviews mit Tänzer*innen, Mitarbeiter*innen und Publikum sowie ethnografische Studien an den koproduzierenden Orten. Eine Praxeologie des kulturellen und ästhetischen Übersetzens wird als tragfähiges Schlüsselkonzept für die Erforschung von Tanz und Kunst eingeführt.
Semantiken des Wandels
Authors: Klymenko Iryna
Published: November 2019

Wandel ist die Meistererzählung der Moderne. Iryna Klymenko untersucht anhand von sechs Fallstudien, wie Wandel vom ausgehenden Mittelalter bis in die Moderne semantisch modelliert wurde und geht den Funktionen dieser Modellierungen ideenhistorisch (Reinhart Koselleck) und gesellschaftstheoretisch (Niklas Luhmann) nach. So entfaltet sie eine neue Perspektive auf die Prominenz und Plausibilität von Wandel als einer modernen Grundformel gesellschaftlicher (Selbst-)Beschreibungen - und damit auf die Moderne und ihre Fundamente selbst.
Tinkering with Political Utopias and Dystopias in DEMOCRACY 3. An Educational Perspective
Authors: Czauderna André
Published: November 2019

The article looks at the possibility of tinkering with political utopias and dystopias in the turn-based political simulation DEMOCRACY 3. Political utopias are understood as coherent sets of political ideas and/or policies following a particular theory of justice, such as political philosophies, political ideologies, or manifestos from political parties. Political dystopias refer to political utopias that do not suit the player's ideological standpoint or that went objectively wrong in the practice of playing. In this sense, playing DEMOCRACY 3 is read as applied political philosophy which might be utilized in political education. The contribution reconstructs the game's implicit learning possibilities and exemplifies observable learning processes, which become visible in »affinity spaces« around the game, for example, on platforms such as YouTube, when players present and discuss their own realizations of utopian or dystopian policies in Let's Play videos.
"Everything is true; nothing is permitted". Utopia, Religion and Conspiracy in ASSASSIN'S CREED
Authors: Wildt Lars de
Published: November 2019

This chapter analyses the Assassin's Creed series, which frames religion as a power play between two opposing utopian-dystopian conspiratorial societies throughout history: the Assassins and Templars. It starts with a review of the relevant literature on Utopia, religion and conspiracy, and then proceed in two sections. The first section argues that the series' original premise monopolizes the Assassins' project as utopian. The Utopia of the Assassins' secularized secret society tries to create space for its »not-place« (Utopia) in the Holy Land of Jerusalem in the year 1191. This secular Utopia is set against the outside invasion of the Catholic dystopian Templar crusaders. The second section of the paper will trace the development of the series' characters, settings and stories between the first game in 2007 and its most recent release (at time of writing) in 2018 to argue that the idea of Utopia comes increasingly to overlap with the dystopia of the other. That is, that the Assassins' dystopia is the Templar's Utopia and vice versa. Cynically put, both sides are equally legitimate in their striving toward contrasting Utopia, by vying for full control over historical societies: everything is true. Nothing is permitted.
Designing Rituals Instead of Ceremonies. The Meaningful Performance of Violence in Video Games
Authors: Brandis Rüdiger , Boccia Alex
Published: November 2019

The research of violence in video games has been mainly centered around the question of whether playing video games makes players more aggressive. Within this question, two major approaches remain the most prominent: on one hand, the focus on the content of media itself, and on the other hand, the user as the constitutive agent. Instead, we propose a perspective on violence in video games as part of an interactive process, in which both the player and the game system are actively involved as part of a performance through which meaning is created. We analyze these processes as ceremonies and rituals, which enables us to distinguish between two very different approaches to designing and experiencing violence in video games. The difference between the two lies in what they convey. While a ceremony indicates a status, a ritual transforms an agent from one state into another passing through a liminal phase. Using these classifications enables us to distinguish those mechanics that utilize violence to signify the status of players and their skills (ceremony) from those that use a system to tell the player something about the significance and meaning of the action while also offering a choice (ritual). Both approaches have their merit, depending on what a designer wants to achieve. As game genres and their mechanics are manifold, our analysis focuses on close quarters combat in Action-Adventures/RPGs. Through examination of the macro elements of fights in Dark Souls and Gothic, we analyze violence as part of a social drama.
