The uphill challenge
(2017)
TO INCREASE THE INFORMATION SECURITY AWARENESS AMONG THEIR WORKFORCE AND TO ACHIEVE SECURE INFORMATION SYSTEMS, DECISION-MAKERS EMPLOY MEASURES OF INFORMATION SECURITY, SUCH AS SECURITY POLICIES OR ASSOCIATED TRAINING AND EDUCATIONAL PROGRAMS. HOWEVER, THESE MEASURES MIGHT STRESS EMPLOYEES. THIS IS TRUE IF, FOR INSTANCE, INFORMATION SECURITY MEASURES ARE PERCEIVED AS DIFFICULT TO UNDERSTAND, AS AN INVASION OF PRIVACY, OR IF THEY GIVE RISE TO CONFLICTS OF INTEREST. CONSEQUENTLY, A MULTI-FACETED PERSPECTIVE ON EMPLOYEES' STRUGGLE WITH INFORMATION SECURITY IS DISCUSSED.
PRO-CYCLICALITY OF COLLATERAL HAIRCUTS AND MARGINS HAS BECOME A WIDELY PROCLAIMED BEHAVIOUR BUT EMPIRICAL EVIDENCE ON THIS TOPIC IS QUITE SPARSE AND THE DISCUSSIONS ARE PRIMARILY DRIVEN BY INSIGHTS DERIVED FROM THEORETICAL MODELS. BASED ON A UNIQUE DATA SET, WE CONSTRUCT A MEASURE OF SYSTEMIC ILLIQUIDITY OF BOND COLLATERALS AND APPLY BUBBLE DETECTION TECHNIQUES TO IDENTIFY IRRATIONAL BEHAVIOUR AND PRO-CYCLICAL TENDENCIES. FINALLY, WE PROPOSE A QUANTITATIVE TRIGGER AND DESIGN FOR MACROPRUDENTIAL HAIRCUT ADD-ONS.
TechQuartier to boost the start-up scene in Frankfurt am Main : interview with Sebastian Schäfer
(2017)
Interview with Sebastian Schäfer, Managing Director TechQuartier, Frankfurt
ROBO-ADVICE HAS THE POTENTIAL TO DISRUPT THE MARKET FOR FINANCIAL ADVICE. ALGORITHMS ALREADY DELIVER LOW-COST, AUTOMATIC, AND STANDARDIZED INVESTMENT GUIDANCE TO CLIENTS FROM ALL WEALTH LEVELS AND ESPECIALLY TO THOSE PREVIOUSLY EXCLUDED FROM PERSONAL FACE-TO-FACE ADVICE. TODAY’S OFFERINGS CONCENTRATE ON CONVENIENCE AND COMPLEXITY REDUCTION, COUPLED WITH PASSIVE INVESTMENTS. THE NEXT STEP WILL ADVANCE ALGORITHMS TO DELIVER TAILOR-MADE DECISION SUPPORT FOR THE GROWING NUMBER OF SELF-DIRECTED INVESTORS. THIS ARTICLE PRESENTS REAL-LIFE EMPIRICAL RESULTS ON THE INTRODUCTION OF A PORTFOLIO OPTIMIZATION TOOL THAT GUIDES BROKERAGE CLIENTS TOWARDS INDIVIDUAL OPTIMAL PORTFOLIOS.
IN COMPARISON TO TRADITIONAL IT PARADIGMS, CLOUD COMPUTING ENABLES TO OBTAIN DESIRED COMPUTING RESOURCES ON-DEMAND WITHOUT REQUIRING LARGE, UPFRONT INVESTMENTS AND TO DYNAMICALLY ADAPT AND SCALE THESE RESOURCES TO VARYING BUSINESS REQUIREMENTS. HOWEVER, CLOUD COMPUTING IS NOT A PANACEA. THIS DRIVES THE NEED TO EXAMINE THE SPECIFIC REASONS AND REQUIREMENTS FOR CLOUD ADOPTION IN PRACTICE. HERE, WE FOLLOW AN ANALYTICAL APPROACH TO EXAMINE CLOUD ADOPTION BY CONDUCTING A LITERATURE SURVEY AND AN EMPIRICAL STUDY.
THE RECENT EVOLUTION OF SMART CONTRACTS AND THEIR FAST ADOPTION ALLOW TO RETHINK PROCESSES AND TO CHALLENGE TRADITIONAL STRUCTURES. THEREFORE, WE INTRODUCE THE UNDERLYING TECHNOLOGY AND RECENT IMPROVEMENTS. FURTHER, WE PROVIDE AN OVERVIEW OF HOW THE INSURANCE SECTOR MAY BE AFFECTED BY BLOCKCHAIN TECHNOLOGY AND SMART CONTRACTS. WE SHOW AN EXEMPLARY USE CASE AND EMPHASIZE CURRENT CHALLENGES AND LIMITATIONS IN THIS AREA.
Mutualistic interactions between plants and animals can affect both plant and animal communities, and potentially leave imprints on plant demography. Yet, no study has simultaneously tested how trait variation in plant resources shapes the diversity of animal consumers, and how these interactions influence seedling recruitment. Here, we analyzed whether (i) phylogenetic diversity and functional diversity of fruiting plants were correlated with the corresponding diversity of frugivorous birds, and (ii) whether phylogenetic diversity and functional identity of plant and bird communities influenced the corresponding diversity and identity of seedling communities. We recorded mutualistic interactions between fleshy-fruited plants and frugivorous birds and seedling communities in 10 plots along an elevational gradient in the Colombian Andes. We built a phylogeny for plants/seedlings and birds and measured relevant morphological plant and bird traits that influence plant-bird interactions and seedling recruitment. We found that phylogenetic diversity and functional diversity of frugivorous birds were positively associated with the corresponding diversities of fruiting plants, consistent with a bottom-up effect of plants on birds. Moreover, the phylogenetic diversity of seedlings was related to the phylogenetic diversity of plants, but was unrelated to the phylogenetic diversity of frugivorous birds, suggesting that top-down effects of animals on seedlings were weak. Mean seed mass of seedling communities was positively associated with the mean fruit mass of plants, but was not associated with the mean avian body mass in the frugivore communities. Our study shows that variation in the traits of fleshy-fruited plants was associated with the diversity of frugivorous birds and affected the future trajectory of seedling recruitment, whereas the morphological traits of animal seed dispersers were unrelated to the phylogenetic and functional structure of seedling communities. These findings suggest that bottom-up effects are more important than top-down effects for seed-dispersal interactions and seedling recruitment in diverse tropical communities.
Este artigo visa discutir os modelos de síntese pressupostos pela dialética negativa de Adorno através de aproximações de temáticas maiores da filosofia de Karl Marx. Isto nos permitirá qualificar melhor a natureza materialista da dialética negativa adorniana, abordando inclusive o impacto político de certas elaborações conceituais.
La risa es uno de los temas menos estudiados en la obra de Walter Benjamin; sin embargo, constituye una de las claves para la comprensión de lo que el crítico alemán consideró que podría ser una politización del arte. En este artículo tratamos de desgranar el lugar de la risa en la teoría estética y política de Benjamin a partir de su conferencia «El autor como productor». Desde ese punto nos proponemos introducir su lectura de Bertolt Brecht, así como su polémica con Theodor W. Adorno.
O Objetivo deste artigo consiste em apresentar fundamentos da proposta epistemológica de Jürgen Habermas, identificados em obras precedentes à sua Teoria do agir comunicativo. A partir de Teoria analítica da ciência e dialética será explorada a proposta do autor, tendo percorrido antecipadamente pela querela entre Popper e Adorno; posteriormente busca-se analisar como Habermas, em debate com seus contemporâneos, retrata sua proposta em Técnica e ciência como ideologia, considerado um marco para a Escola de Frankfurt.
Este escrito reconstruye la problematización que Wellmer hace del planteamiento adorniano sobre el hundimiento de la metafísica y su articulación con una eventual alternativa estética para, inmediatamente, explorar la propuesta integral de la tercera Escuela de Frankfurt en torno a la eticidad democrática, sustentable desde los planteamientos de Dubiel, Honneth y Wellmer, como alternativa para una superación de las aporías que Adorno y la primera Escuela de Frankfurt no logran superar, categoría que nos remite en Habermas a su noción del patriotismo constitucional donde adquiere toda su proyección política postconvencional la eticidad democrática y que concurre en la figura de una opinión pública contestataria, que tanto Habermas como Nancy Fraser han querido fundamentar, como opción contra hegemónica y potencialmente emancipatoria en las sociedades en conflicto, para finalmente articular lo anterior con el talante cosmopolita del republicanismo que enfatiza, desde Nussbaum, Bohman y de nuevo Fraser, la perspectiva transnacional que las aspiraciones emancipatorias pueden tener en un mundo global, cuyas sinergias confluyen y concretan no solo estrategias de convivencia democrática nacionales e internacionales sino además, a través de las mismas, la superación concreta —no meramente ética o estética— de fenómenos de autoritarismo político y alienación social, en tanto mediación idónea, aunque parcial, de reconciliación en las sociedades complejas.
Теорія напівосвіти Адорно була вперше представлена як доповідь на З’їзді німецьких соціологів (1959). В ній розглядаються тенденції, що відбуваються у сучасній освіті і обумовлюють її кризу, яка загострюється у соціокультурних контекстах пізнього капіталізму. Теорія напівосвіти переосмислює і актуалізує концептуалізації освіти та культури у німецькій класичній філософії, марксизмі і фройдизмі, розкриваючи діалектику просвітництва через діагностику спотворень і деформацій освіти в опціях відчуженого духа, що криє у собі небезпеку ліквідації культури, яка перетворюється на масову, і руйнації людського буття через інструменталізацію свідомості та примусову адаптацію. Напівосвіта паразитує на ідеї освіти, яка є внутрішньо суперечливою через поєднання настанов на автономію та адаптацію. Подолання цієї суперечності можливе через негативну діалектику, яка комплементарно поєднує критику суспільства і критику освіти, відкриваючи для них нові горизонти
Theodor W. Adorno publicou o ensaio “Teoria da semiformação” (Theorie der Halbbildung) em 1959. A partir da publicação deste texto, observou-se sua relevância, sobretudo para que se pudesse compreender a maneira como a indústria cultural determinava a produção de prejuízos significativos no processo formativo. Desde então, a conquista do espírito feita pelo caráter fetichista dos produtos da indústria cultural, sendo esta uma das definições de Adorno sobre o conceito de Halbbildung, impulsionou a realização de muitas pesquisas sobre os danos decorrentes desta conquista na formação. Porém, investigar as atuais características do processo semiformativo não resulta na aplicação direta dos conceitos propostos por Adorno no final da década de 1950. Sendo assim, é preciso que tais conceitos sejam revitalizados por meio da análise das atuais mediações históricas. Seguindo essa linha de raciocínio, o principal objetivo deste artigo é argumentar que a reflexão crítica sobre o modo como a semiformação se renova, na atual sociedade da chamada cultura digital, torna-se fundamental para que se possam elaborar considerações sobre o renascimento da formação (Bildung).
To imitate all that is hidden. The place of mimesis in Adorno’s theory of musical performance
(2017)
The article examines the use of the concept of mimesis in Adorno’s notes towards a theory of musical performance. In trying to idiosyncratically define the latter as “reproduction”, Adorno relied on a framework elaborating on concepts introduced by Arnold Schoenberg, Hugo Riemann and Walter Benjamin – a framework that the article discusses insofar as it deals with the problem of mimesis. Specific attention is devoted to the relation between Benjamin’s essays on language and translation and Adorno’s theory of notation, that soon became the crucial aspect of his theory of reproduction. Given the shortcomings of Adorno’s theory, which in the end did not achieve its goals, the article proposes to capitalize on his terminology while at the same time rethinking his framework in the light of recent musicological paradigms for the study of musical performance. On the whole, the article shows that it was Adorno’s philosophical assumptions – in particular the theses of music’s non-intentionality and of its non-similarity to language – that prevented him from convincingly theorizing musical performance, and suggests an alternative framework for future research.
Examina-se aqui um estudo realizado por Theodor Adorno acerca das locuções radiofônicas do ativista político de extrema direita nos EUA, o pastor Martin Luther Thomas, à década de 30. Detendo-se nestes discursos por meio do método da análise de conteúdo, Adorno buscava entender os motivos que levaram os indivíduos a perpetuarem as mesmas relações econômicas que suas forças haviam superado, em vez de substituí-los por uma forma de organização social superior e mais racional. Passados mais de 70 anos, este estudo é, sem dúvidas, um instrumental precípuo para compreendermos o atual cenário social, principalmente o político.
Este artigo tem como objetivo principal analisar a relação entre utopia negativa e catástrofe na Estética de Adorno. O filósofo argumenta que a arte moderna é associada a um tipo de utopia que não é uma representação positiva do que a sociedade deveria ser. A utopia negativa apenas mostra o que a sociedade não deveria ser. A obra de arte está então carregada de contradições de uma sociedade não reconciliada. Tal explica por que a arte moderna e nova é tão recorrentemente caracterizada pelo feio, o repulsivo, o negro e o catastrófico. Na formulação de Adorno, a obra de arte se constitui como negação determinada da sociedade administrada. Como tal, a obra de arte é também negação determinada da cultura administrada, isto é, sua constituição é dada pela negação determinada dos padrões da Indústria Cultural e da tradição artística.
Com o advento da modernidade a filosofia passou a exigir que a religião prestasse contas à razão. A filosofia da religião de Kant é um exemplo desse tipo de iniciativa. Kant propôs julgar a religião no tribunal da razão. Mais de 200 anos depois, Habermas buscou renovar o projeto kantiano. Nosso trabalho visa esclarecer o modo como cada autor realiza o julgamento da religião no tribunal da razão. Além disso, discutiremos a relevância desse tipo de abordagem proposta por ambos os filósofos.
O presente trabalho aborda o problema da compreensão e justificação do conceito habermasiano de tolerância (Toleranz) nas sociedades marcadas por diferentes e incompatíveis (conflitantes) imagens de mundo (verschiedene und unverträgliche Weltbildern), onde se elaboram e articulam os contextos da justificação (Kontexte der Rechtfertigung) e o contexto da tolerância (Kontext der Toleranz). A meu ver, Habermas estabelece uma distinção ambivalente entre tolerância e não discriminação, baseada em uma dissonância cognitiva (kognitive Uneinheitlichkeit) aplicável às imagens de mundo (Weltbildern) concorrentes e mutuamente excludentes, resultando em uma diferenciação das expectativas normativas referente à resolução de dilemas que envolvem formas de vida culturalmente diferenciadas. Nas situações em que as objeções a crenças e práticas de uma forma de vida particular não se encontram baseadas em razões públicas (öffentliche Gründe), não caberia falar em tolerância, mas na luta pela igualdade de direitos de cidadania e reconhecimento de direitos culturais. A dificuldade consiste em declarar quais crenças e práticas seriam “eticamente objetáveis ou erradas”, mas que não poderiam ser igualmente julgadas, com base em “razões públicas”, como “moralmente rejeitáveis”, dada a existência de razões de aceitação (que não eliminam, mas superam as razões de objeção) e, portanto, objeto da tolerância, bem como aquelas crenças e práticas que não poderiam ser toleradas sob qualquer justificação moral baseada em “razões públicas” (crenças e práticas igualmente “eticamente objetáveis ou erradas” e “moralmente rejeitáveis”). Além disso, como ressalta Forst, nem sempre é possível estabelecer quais razões são “públicas” e podem constituir o fundamento de objeções razoáveis às crenças e práticas de alguém considerado “eticamente diferente” de “nós” ou ainda, como assevera Lafont, se estas mesmas razões estariam “disponíveis”.
O Direito liberal procede da ideia kantiana de um acordo de arbítrios conforme uma lei de liberdade externa, assegurando a ideia de um radicalismo pós-religioso de legitimidade e sem fundamentos metafísicos (Nozick). Habermas aproveita os sentidos do Direito liberal de Nozick e Kant, liberdade e não fundacionismo e associa a crítica ao Direito socialista a uma visão construtiva que, assim como Rawls (e seu pluralismo razoável), busca pensar as pretensões de um Direito democrático no espaço público. Superando a dicotomia socialista-liberal do século XX, Habermas busca manter a democracia e a pós-metafísica como elementos de um Direito pluralista que através do procedimentalismo institucionalizador das conquistas do espaço público movido pela razão comunicativa, possa assegurar as pretensões de legitimação da liberdade com as necessárias visões da “Teoria Crítica” sobre a legitimação da democracia no capitalismo tardio, preservando as autonomias pública e privada da tradição republicana e liberal de Kant.
O artigo apresenta brevemente as possíveis implicações da recusa da clonagem, do DGPI e da eugenia liberal para o formalismo da ética discursiva, pois tal recusa poderia sugerir a eleição de um modo de vida privilegiado, (uma vida humana baseada na “inteireza do patrimônio genético”). Apresentamos os elementos do formalismo ético de Habermas e os argumentos centrais de sua crítica às intervenções eugênicas. Sugerimos que a defesa habermasiana da manutenção da indisponibilidade do patrimônio genético (por seu papel na autocompreensão ética do humano como ser livre e autônomo) situa essa matéria da filosofia moral na tensão entre a ação comunicativa, no qual o debate deveria ter sede, e a ação instrumental, que ameaça monopolizar as decisões sobre o tema.
Schopenhauer afirma que uma ética não dogmática requer leis demonstráveis derivadas da experiência. Nesse sentido o fundamento de uma ética deve ser uma metafísica imanente, que sustente, na experiência possível, suas afirmações, e que seja, por isso mesmo, capaz de dar de uma vez por todas um fundamento legítimo à moral. A fundamentação da moral schopenhaueriana segue, portanto, uma argumentação muito próxima de uma metodologia científica. Para Schopenhauer a filosofia deve se aproximar mais de uma cosmologia do que da teologia. Max Horkheimer em “O pensamento de Schopenhauer em relação à ciência e à religião” destaca a fecundidade de tal posição filosófica e atualiza a importância de Schopenhauer tanto para sua formação quanto para uma legítima interpretação da modernidade. Acompanhamos, neste artigo tanto os aspectos fundamentais da fundamentação schopenhaueriana da moral, quanto aspectos da interpretação de Horkheimer da empreitada do filósofo.
Aproximações entre Nietzsche e Adorno acerca da massificação da cultura e da vida administrada
(2017)
Pretendemos pensar as relações entre arte e sociedade, tendo sempre em mente a tensão irredutível entre a autonomia e a heteronomia de uma em relação a outra. Para tanto, traçaremos uma análise dos argumentos principais a respeito dessa relação dialética, em dois momentos distintos da reflexão filosófica sobre o tema. Em um primeiro momento, traremos a defesa de uma certa autonomia da arte com referência não apenas à sociedade que a produz, como também aos valores morais que são ensinados através dela, com as reflexões e, sobretudo, com as críticas de Nietzsche sobre suas interpretações da tragédia clássica, a partir principalmente de O Nascimento da Tragédia, para, em um segundo momento, poder traçar um paralelo dessa argumentação com a constatação de Adorno a respeito da instrumentalização e da comercialização da arte, no contexto contemporâneo, expondo algumas das críticas de Nietzsche realizadas no séc. XIX sobre as produções culturais gregas do séc. IV a. C. e contextualizando-as em relação aos fenômenos estéticos contemporâneos.
У статті розглядаються соціокультурні контексти створення і рецепції теорії напівосвіти Т. Адорно на основі широкого застосування біографічного методу, що дозволило розкрити інтенціональність цієї теорії крізь призму спогадів учнів і колег. Запропоновано аргументативне підкріплення тези Ю. Габермаса про внутрішню роздвоєність теоретизування Адорно. Аналізуються інтерпретаційні схеми поняття Bildung (освіта, культура, формування) у німецькому ідеалізмі, де домінує семантика формування, а патології цього процесу відповідно концептуалізуються як деформації та розпад форм у різноманітніх маніфестаціях напівосвіти. Теорія напівосвіти є передусім діагностикою стану сучасних розвинутих суспільств, де засобами масової культури постійно продукуються такі патології, як відчуження і стани масового психозу. Цьому сприяє також тенденція рефеодалізації, яка, в свою чергу, виступає також симптоматикою духовної кризи постсучасності. Одним з проявів цієї кризи є радикальний антипод освіти - антиосвіта, яка є наслідком відмови сучасних навчальних і виховних практик від гуманістичної ідеї освіти. Для виходу із стану кризи критичної рефлексії потребують не тільки напівосвіта і антиосвіта, а й сама ідея освіти.
Morphological malformations induced by tributyltin (TBT) exposure during embryonic development have already been characterized in various taxonomic groups, but, nonetheless, the molecular processes underlying these changes remain obscure. The present study provides the first genome-wide screening for differentially expressed genes that are linked to morphological alterations of gonadal tissue from chicken embryos after exposure to TBT. We applied a single injection of TBT (between 0.5 and 30 pg as Sn/g egg) into incubated fertile eggs to simulate maternal transfer of the endocrine disruptive compound. Methyltestosterone (MT) served as a positive control (30 pg/g egg). After 19 days of incubation, structural features of the gonads as well as genome-wide gene expression profiles were assessed simultaneously. TBT induced significant morphological and histological malformations of gonadal tissue from female embryos that show a virilization of the ovaries. This phenotypical virilization was mirrored by altered expression profiles of sex-dependent genes. Among these are several transcription and growth factors (e.g. FGF12, CTCF, NFIB), whose altered expression might serve as a set of markers for early identification of endocrine active chemicals that affect embryonic development by transcriptome profiling without the need of elaborate histological analyses.
El texto se propone exponer críticamente algunos contenidos fundamentales del concepto de totalidad y su importancia para el pensamiento dialéctico. Partiendo de una crítica de la concepción hegeliana de totalidad, busca sin embargo defender este concepto, aunque reconstruido desde un giro materialista a partir de la filosofía desarrollada por Theodor W. Adorno. El concepto de totalidad cambiaría su significado y función a partir de la crítica materialista, pasando de la idea de un todo determinado y definitivo, a un criterio epistemológico y normativo para oponerse con efectividad a la imposición de una totalidad social.
A política de identidade e o conceito de reconhecimento têm se transformado em questões dominantes da teoria política contemporânea. Como conceito, o reconhecimento significa que um indivíduo ou grupo social reivindica o direito a ter sua identidade reconhecida, de forma direta ou através da mediação de um conjunto de instituições. As teorias que tem problematizado estas questões abordam tanto temas teóricos importantes como questões políticas centrais do nosso tempo, como a definição de direitos das minorias, reivindicações de autodeterminação nacional ou os desafios colocados por nossas sociedades cada dia mais multiculturais. Dessa forma, o objetivo central do presente artigo é apresentar e discutir os argumentos centrais de Charles Taylor, Axel Honneth e Nancy Fraser que têm se transformando em essenciais para esta discussão, enfatizando o debate em torno da relação entre reconhecimento e redistribuição, e mais especificamente entre o problema da injustiça baseada na questão da identidade e o problema da injustiça econômica. Por último, tentaremos entender algumas das implicações teóricas e políticas do discurso da diferença e das teorias do reconhecimento dentro de uma perspectiva conceptual mais ampla.
O reconhecimento é um conceito normativo. Ao reconhecermos alguém como portador de determinadas características ou capacidades, reconhecemos seu status normativo e estamos assumindo responsabilidade por tratar este alguém de determinada forma. O não reconhecimento, neste caso, pode significar privação de direitos e marginalização; em uma democracia pode impossibilitar indivíduos ou grupos de desfrutar o ideal igualitário democrático, por exemplo. Nas últimas três décadas, a reflexão sobre esta categoria se aprofundou e assumiu maior importância no debate entre liberalismo e comunitarismo em paralelo às demandas, por vezes pelas conquistas, de grupos e minorias (LGBTQIA, portadores de necessidades especiais, feministas, indígenas, étnicos, etc.) que se sentem não reconhecidos e se engajam em movimentos políticos através de lutas por reconhecimento. Retomaremos, aqui, o desenvolvimento do conceito de “eticidade” empreendido por Axel Honneth em Luta por reconhecimento (1992), obra fundamental para a reflexão sobre o tema. O autor situa sua teoria no meio termo entre a moral kantiana e as éticas comunitaristas: sua concepção é formal por entender que normas universais são condições de algumas possibilidades, mas é substantiva por se orientar pelo fim da autorrealização humana.
O presente estudo tem como objetivo investigar a ideia de reconhecimento jurídico na teoria de Axel Honneth, o que se dará mediante análise da obra Luta por Reconhecimento. Honneth, ancorado nas teorias de Hegel e Mead, estabelece o papel do direito como esfera de reconhecimento individual e seu potencial de asseguramento do autorrespeito. Empreende-se uma reconstrução da teoria honnethiana no atinente aos papéis desempenhados pelo direito na teoria da Luta por Reconhecimento de Axel Honneth, para em seguida, a partir da leitura que o autor desenvolve da teoria de Thomas Marshall, analisar o papel desempenhado pelos direitos subjetivos fundamentais como medium de sedimentação e ampliação de novas formas de reconhecimento e cidadania.
Intersubjetividade e ontologia social nas revisões da teoria do reconhecimento de Axel Honneth
(2017)
O artigo sintetiza as revisões que Axel Honneth impôs a sua obra após a recepção crítica de Luta por reconhecimento (1992), propondo compreendê-las como passos intermediários em direção ao novo modelo crítico apresentado em O direito da liberdade (2011), chamado por Honneth de reconstrução normativa. O objetivo não é examinar as determinações de método da reconstrução normativa, mas percorrer o caminho intelectual de Honneth entre suas duas obras principais, explicitando as revisões e os novos pressupostos da obra “madura” do autor. Essas revisões, concentradas ao redor de uma compreensão considerada por Honneth como mais adequada da intersubjetividade e da ontologia social, escoram e justificam as decisões de método do último livro. Desde o início de sua elaboração teórica, Honneth teve de lidar com a objeção de cometer sistematicamente uma falácia naturalista ao buscar o fulcro de uma teoria crítica da sociedade na experiência concreta do sofrimento. Mesmo Luta por reconhecimento ainda esteve justificadamente sujeito à mesma crítica, como Honneth viria a admitir. Argumento que o objetivo das revisões levadas a cabo na década de 2000 foi sanar essa lacuna, encontrando, por um lado, um índice de racionalidade interno ao próprio ato de reconhecimento, e, por outro, um índice de racionalidade presente nas normas e práticas sociais sedimentadas historicamente por relações de reconhecimento.
Trata de uma investigação teórica que problematiza os contornos de uma pedagogia crítica na atualidade. Adota a perspectiva do filósofo Axel Honneth como fio condutor da análise, especificamente os textos em que ele discute as características contemporâneas de uma teoria adjetivada de crítica. Após descrever seu posicionamento, extrai alguns sentidos para o empreendimento crítico no âmbito de uma pedagogia da educação física.
No presente artigo analisamos a ideia de solidariedade na teoria da justiça de Axel Honneth. Honneth em sua obra atualiza a teoria hegeliana da eticidade e concebe a existência de esferas de liberdade, sendo que uma delas é a liberdade social, na qual se situam relações pessoais, mercado e instituições políticas. Em O Direito da Liberdade Honneth desenvolve uma teoria em que busca analisar os problemas de desenvolvimento da democracia nas sociedades contemporâneas, e erige a solidariedade como um dos pressupostos normativos para a construção de uma democracia virtuosa, ancorada na participação cidadã.
Objectives: Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare, distinct pulmonary vascular disease, and therefore, there is a lack of data regarding its clinical presentation, diagnosis, and management at a national basis. We aimed to describe the demographics and management of patients with CTEPH in Northern Greece. Methods: We conducted a retrospective, observational study by a joint collaboration between two pulmonary hypertension expert centers in Greece, and the study included patients diagnosed with CTEPH. The patient population was divided into two groups depending on their operability. Results: Overall, 27 consecutive patients were included (59% female, mean age 59.3±15.1 years). Dyspnea and fatigue were the most common presenting symptoms. History of pulmonary embolism was present in 82%. Of patients, 18 (67%) were assessed as operable, of whom 10 (55%) finally underwent pulmonary endarterectomy (PEA). There were no differences in symptoms, WHO functional class, 6-min walking test distance, and hemodynamics between the operable and nonoperable groups. At the end of follow-up, all non-operable and operable patients who did not receive surgical treatment were treated with at least one pulmonary hypertension-specific drug. Conclusion: This is the first report that presents data of patients diagnosed with CTEPH in Greece. The percentage of patients who underwent surgical treatment is lower but approaches the reported rates in large registries. Considering that PEA is a relatively safe and potentially curative surgical procedure, we emphasize the need for establishing a designated PEA center in Greece. Keywords: Chronic thromboembolic pulmonary hypertension, pulmonary endarterectomy, registry, riociguat.
Various strategies have been employed to speed tissue regeneration using bioactive molecules. Interestingly, platelet concentrates derived from a patient’s own blood have been utilized as a regenerative strategy in recent years. In the present study, a novel liquid platelet formulation prepared without the use of anti-coagulants (injectable-platelet-rich fibrin, i-PRF) was compared to standard platelet-rich plasma (PRP) with gingival fibroblasts cultured on smooth and roughened titanium implant surfaces. Standard PRP and i-PRF (centrifuged at 700 rpm (60× g) for 3 min) were compared by assays for fibroblast biocompatibility, migration, adhesion, proliferation, as well as expression of platelet-derived growth factor (PDGF), transforming growth factor-β (TGF-β), collagen1 (COL1) and fibronectin (FN). The results demonstrate that i-PRF induced significantly higher cell migration, as well as higher messenger RNA (mRNA) levels of PDGF, TGF-β, collagen1 and fibronectin when compared to PRP. Furthermore, collagen1 synthesis was highest in the i-PRF group. These findings demonstrate that liquid platelet concentrates can be formulated without the use of anticoagulants and present much translational potential for future research. Future animal and clinical trials are now necessary to further investigate the potential of utilizing i-PRF for soft tissue regenerative protocols in combination with various biomaterials.
Razina pročišćenosti alogenoga koštanog bloka = Variant purification of an allogeneic bone block
(2017)
Svrha: Ovaj kratak tekst izvještava o histološkoj analizi sastava komercijalno raspoloživih alogenih koštanih blokova Maxgraft®. Materijali i metode: Na temelju objavljenih histoloških metoda prazni uzorci alogenih koštanih blokova Maxgraft® dekalcificirani su, dehidrirani i uloženi u parafin prije histološkog i histokemijskog bojenja. Nakon toga na prerezima su se procjenjivala obilježja materijala, poput strukture koštanoga matriksa i druge komponente, uključujući kolagen ili stanice/stanične ostatke. Rezultati: Uočeno je da ovi koštani blokovi imaju trabekularnu strukturu s lamelarnom podorganizacijom. Dodatno su nađeni i stanični ostatci unutar lakuna osteocita i na vanjskim površinama trabekula zajedno s ostatcima intertrabekularnog masnog i vezivnog tkiva, te kolagene strukture, vezivno-tkivne stanice i stanični ostatci. Zaključak: U skladu s dosadašnjim istraživanjima, podatci iz ovoga teksta pokazuju da neke od certificiranih tehnika pročišćavanja ne omogućuju proizvodnju alogenog materijala bez organskih stanica i tkivnih komponenata.
Objective: to systematize the strengths and challenges of Axel Honneth’s Theory of Recognition, and to reflect on these as support for research in health care. Method: this is a reflection article which considers the potential of incorporating the category of recognition in the Honnethian proposition for research, understanding, exercising of practice and management of health care. Results: the process of recognition promotes the exploration and understanding of relations of power and respect, above all in terms of conflict which are ascribed to these. As a result, it indicates support for diagnoses and structuring nuclei for overcoming oppressive and unequal practices, with consequences for dealing with situations of insecurity, weaknesses in self-esteem and vulnerabilities in the interactions between the subjects, which are configured as contemporary challenges. Conclusion: in the scientific exploration of care, management and public policies in health, this theoretical framework can assist in the visibility of the context and in its critical knots, in order to promote autonomy and human dignity, which are relevant for the interpersonal relations in the processes of care, with fruitful contributions to the qualification of the health care.
Objetivo: sistematizar as potencialidades e desafios da Teoria do Reconhecimento, de Axel Honneth, e refletir sobre eles como subsídio às pesquisas em saúde.
Método: trata-se de artigo de reflexão que toma o potencial da incorporação da categoria reconhecimento na propositura honnethiana para pesquisa, compreensão, exercício e gestão do cuidado em saúde.
Resultados: o processo de reconhecimento favorece a exploração e a compreensão das relações de poder e respeito, sobretudo em termos do conflito a elas circunscrito. Dessa forma, indica subsídios para diagnósticos e núcleos estruturantes para a superação de práticas opressivas e desiguais, com desdobramentos para lidar com situações de insegurança, fragilidades na autoestima e vulnerabilidades nas interações entre os sujeitos, que configuram desafios contemporâneos.
Conclusão: na exploração científica do cuidado, gestão e políticas públicas em saúde, este referencial teórico pode auxiliar na visibilidade do contexto e seus nós críticos, para favorecer a autonomia e a dignidade humana, relevantes para as relações interpessoais nos processos de cuidado, com contribuições profícuas à qualificação da atenção à saúde.
From reciprocal recognition to a society that is properly 'social' : on Axel Honneth's recent work
(2017)
This paper addresses Axel Honneth's recent endeavors to defend his theory of justice, broadly described in Freedom's right (2011) as an analysis of society. The paper begins by exposing Honneth's model as a theory of institutional intersubjectivity rather than a theory of the struggle for recognition. This model, however, was subject to criticism due to its supposed acceptance of the capitalistic market economy as a social order. In order to defend it from such objections, Honneth (2016) exposes the normative core of socialist ideals as a version of social freedom. Finally, he presents a distinction between two forms of political intervention: an internal and an external struggle for recognition – and asserts the advantages of the former.
Este artigo apresenta uma discussão sobre a obra recente de Axel Honneth. Começando por uma exposição de seu projeto teórico mais amplo, descrito em O direito da liberdade (2011) como uma teoria da justiça sociologicamente ancorada, o artigo demonstra como Honneth se move da ideia de uma luta por reconhecimento em direção à ideia de intersubjetividade institucional. Este movimento, porém, é acompanhado por críticas que vêm nesta passagem o abandono das ambições críticas de seu modelo e um compromisso reformista com a ordem capitalista de mercado. A fim de responder a estas objeções, Honneth propõe uma reatualização da ideia do socialismo (2015) a partir da noção de liberdade social, concluindo com uma distinção entre duas formas de luta por reconhecimento, uma interna e outra externa – e defendendo as vantagens da primeira.
Objective: This study examines the interrelations of parenting practices, emotional climate, and household chaos in families with children with and without ADHD. In particular, indirect pathways from children’s ADHD symptomatology to inadequate parenting and negative emotional climate via household chaos were investigated. Method: Parenting, emotional climate, and household chaos were assessed using questionnaires and a speech sample of parents of 31 children with and 53 without ADHD, aged 7 to 13 years. Results: Group differences were found for certain parenting dimensions, the parent–child relationship, critical comments, and household chaos. While we found significant indirect effects between children’s ADHD and certain parenting dimensions through household chaos, no effects were found for any aspect of emotional climate. Conclusion: Children’s ADHD symptoms translate into inadequate parenting through household chaos, which underlines the need for interventions to improve household organization skills in parents of children with ADHD.
O ensaio traz como base a crítica ao capitalismo, no que se refere aos efeitos negativos que ele impõe aos indivíduos, a partir dos estudos da primeira geração da Escola de Frankfurt. Analisar-se-á a história das ideias a partir de Walter Benjamin, Herbert Marcuse, Theodor Adorno e Max Horkheimer. Benjamin afirma que vive-se a perda da aura das obras de arte, já que a sua comercialização faz com que se perca a essência daquelas obras. Ademais, a imposição da novidade às obras e aos produtos consumidos representa uma ferramenta de manipulação do capitalismo, culminando na pobreza da experiência humana. Marcuse afirma que a sociedade vive o princípio do desempenho, que provoca modos de vida uniformizados, baseados numa concepção de trabalho e diversão homogêneos. Adorno propôs que o tempo livre provocava uma sensação de liberdade nos indivíduos, mas, na realidade, tratava-se do exercício de uma não liberdade, já que as formas de diversão seguiam à risca os padrões exigidos pelo capital. A partir do método adotado pela própria Teoria Crítica, afirma-se que a presente discussão teórica só se torna efetiva quando aplicada à prática, à sociedade atual.
This article is written from the perspective of phenomenology. Its potential gain for a critical human geography is discussed in contrast to the paradigmatic frame of basic assumptions in constructivism. The example of atmospheres will illustrate another theoretical conception of space. In phenomenological view there happens not only a reality of things but also a circum-actuality is not spatially extended like a house or another material objective. Atmospheres are vital qualities (Dürckheim) we feel like a cloud in our sense perception in situations of awareness. This implies the necessity to make a difference between a material body (Körper) and a felt body (Leib). This epistemic knowledge will improve our critique of neoliberal societies, tuned by aestheticisation especially in glamour CBDs of postmodern cities. Finally there is a close link to the work of Michel Foucault, topped off in his The Hermeneutics of the Subject. References to the Critical Theory (Frankfurter Schule) are connected.
Anxiety and politics
(2017)
The English version of this article was first published in 1957. The journal tripleC: Communication, Capitalism & Critique republished it 60 years later in 2017. In this essay, Franz L. Neumann discusses the role of anxiety in politics. The article asks: How does it happen that the masses sell their souls to leaders and follow them blindly? On what does the power of attraction of leaders over masses rest? What are the historical situations in which this identification of leader and masses is successful, and what view of history do the men have who accept leaders? For answering these questions, the author suggests a combination of political economy, Freudian political psychology, and ideology critique. He sees anxiety in the context of alienation. Alienation is analysed as a multidimensional phenomenon consisting of economic, political, social and psychological alienation. Neumann introduces the notions of Caesaristic identification, institutionalised anxiety and persecutory anxiety. The essay shows that fascism remains an actual threat in capitalist societies.
Intestinal carriage of multidrug-resistant bacteria among healthcare professionals in Germany
(2017)
Healthcare professionals (HCP) might be at increased risk of acquisition of multidrug-resistant bacteria (MDRB), i.e., methillicin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE), and multidrug-resistant gram-negative bacteria (MDRGN) and could be an unidentified source of MDRB transmission.
The aim of this study was to determine the prevalence as well as risk factors of MDRB colonization among HCP.
HCP (n=107) taking part in an antibiotic stewardship program, were voluntarily recruited to perform a rectal swab and to fill in a questionnaire to identify risk factors of MDRB carriage, i.e. being physician, gender, travel abroad within the previous 12 months, vegetarianism, regular consumption of raw meat, contact to domestic animals, household members with contact to livestock, work or fellowship abroad, as well as medical treatment abroad and antibiotic therapy within the previous 12 months.
Selective solid media were used to determine the colonization rate with MRSA, VRE and MDRGN. MDRGN were further characterized by molecular analysis of underlying β-lactamases.
None of the participants had an intestinal colonization with MRSA or VRE. 3.7% of the participants were colonized with extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae, predominantly blaCTX-M type. Neither additional flouroquinolone resistance nor carbapenem resistance was detected in any of these isolates. No risk factors were identified to have a significant impact of MDRB carriage among HCP.
A colonization rate of 3.7% with ESBL-producing Enterobacteriaceae is of interest, but comparing it to previously published data with similar colonization rates in the healthy population in the same geographic area, it is probably less an occupational risk.
Objective: Extracorporeal life support (ECLS) is a life-saving procedure used in the treatment of severe cardiogenic shock. Within this retrospective single centre study, we examined our experience in this critically ill patient cohort to assess outcomes and clinical parameters by comparison of ECLS with or without selective left ventricular decompression.
Methods: Between 2004 and 2014 we evaluated 48 adult patients with INTERMACS level 1 heart failure (age 49.7 ± 19.5 years), who received either central ECLS with (n = 20, 41.7%) or ECLS without (n = 28, 58.3%, including 10 peripheral ECLS) integrated left ventricular vent in our retrospective single centre trial.
Results: Follow up was 100% with a mean of 0.83 ± 1.85 years. Bridge to ventricular assist device was feasible in 29.2% (n = 14), bridge to transplant in 10.4% (n = 5) and bridge to recovery in 8.3% (n = 4). Overall 30-day survival was 37.5%, 6-month survival 27.1% and 1-year survival 25.0%. ECLS support with left ventricular decompression showed favourable 30-day survival compared to ECLS without left ventricular decompression (p = 0.034). Thirty-day as well as long-term survival did not differ between the subgroups (central ECLS with vent, ECLS without vent and peripheral ECLS without vent). Multivariate logistic regression adjusted for age and gender revealed ECLS without vent as independent factor influencing 30-day survival.
Conclusion: ECLS is an established therapy for patients in severe cardiogenic shock. Independent of the ECLS approach, 30-day mortality is still high but with superior 30-day survival for patients with ECLS and left ventricular venting. Moreover, by unloading the ventricle, left ventricular decompression may provide an important time window for recovery or further treatment, such as bridge to bridge or bridge to transplant.
Exposure to community violence through witnessing or being directly victimized has been associated with conduct problems in a range of studies. However, the relationship between community violence exposure (CVE) and conduct problems has never been studied separately in healthy individuals and individuals with conduct disorder (CD). Therefore, it is not clear whether the association between CVE and conduct problems is due to confounding factors, because those with high conduct problems also tend to live in more violent neighborhoods, i.e., an ecological fallacy. Hence, the aim of the present study was: (1) to investigate whether the association between recent CVE and current conduct problems holds true for healthy controls as well as adolescents with a diagnosis of CD; (2) to examine whether the association is stable in both groups when including effects of aggression subtypes (proactive/reactive aggression), age, gender, site and socioeconomic status (SES); and (3) to test whether proactive or reactive aggression mediate the link between CVE and conduct problems. Data from 1178 children and adolescents (62% female; 44% CD) aged between 9 years and 18 years from seven European countries were analyzed. Conduct problems were assessed using the Kiddie-Schedule of Affective Disorders and Schizophrenia diagnostic interview. Information about CVE and aggression subtypes was obtained using self-report questionnaires (Social and Health Assessment and Reactive-Proactive aggression Questionnaire (RPQ), respectively). The association between witnessing community violence and conduct problems was significant in both groups (adolescents with CD and healthy controls). The association was also stable after examining the mediating effects of aggression subtypes while including moderating effects of age, gender and SES and controlling for effects of site in both groups. There were no clear differences between the groups in the strength of the association between witnessing violence and conduct problems. However, we found evidence for a ceiling effect, i.e., individuals with very high levels of conduct problems could not show a further increase if exposed to CVE and vice versa. Results indicate that there was no evidence for an ecological fallacy being the primary cause of the association, i.e., CVE must be considered a valid risk factor in the etiology of CD.
One striking observation in Parkinson’s disease (PD) is the remarkable gender difference in incidence and prevalence of the disease. Data on gender differences with regard to disease onset, motor and non-motor symptoms, and dopaminergic medication are limited. Furthermore, whether estrogen status affects disease onset and progression of PD is controversially discussed. In this retrospective single center study, we extracted clinical data of 226 ambulatory PD patients and compared age of disease onset, disease stage, motor impairment, non-motor symptoms, and dopaminergic medication between genders. We applied a matched-pairs design to adjust for age and disease duration. To determine the effect of estrogen-related reproductive factors including number of children, age at menarche, and menopause on the age of onset, we applied a standardized questionnaire and performed a regression analysis. The male to female ratio in the present PD cohort was 1.9:1 (147 men vs. 79 women). Male patients showed increased motor impairment than female patients. The levodopa equivalent daily dose was increased by 18.9% in male patients compared to female patients. Matched-pairs analysis confirmed the increased dose of dopaminergic medication in male patients. No differences were observed in age of onset, type of medication, and non-motor symptoms between both groups. Female reproductive factors including number of children, age at menarche, and age at menopause were positively associated with a delay of disease onset up to 30 months. The disease-modifying role of estrogen-related outcome measures warrants further clinical and experimental studies targeting gender differences, specifically hormone-dependent pathways in PD.
Callous-unemotional traits are characterized by a lack of empathy, a disregard for others' feelings and shallow or deficient affect, such as a lack of remorse or guilt. Neuroanatomical correlates of callous-unemotional traits have been demonstrated in clinical samples (i.e., adolescents with disruptive behavior disorders). However, it is unknown whether callous-unemotional traits are associated with neuroanatomical correlates within normative populations without clinical levels of aggression or antisocial behavior. Here we investigated the relationship between callous-unemotional traits and gray matter volume using voxel-based morphometry in a large sample of typically-developing boys and girls (N = 189). Whole-brain multiple regression analyses controlling for site, total intracranial volume, and age were conducted in the whole sample and in boys and girls individually. Results revealed that sex and callous-unemotional traits interacted to predict gray matter volume when considering the whole sample. This interaction was driven by a significant positive correlation between callous-unemotional traits and bilateral anterior insula volume in boys, but not girls. Insula gray matter volume explained 19% of the variance in callous-unemotional traits for boys. Our results demonstrate that callous-unemotional traits are related to variations in brain structure beyond psychiatric samples. This association was observed for boys only, underlining the importance of considering sex as a factor in future research designs. Future longitudinal studies should determine whether these findings hold over childhood and adolescence, and whether the neuroanatomical correlates of callous-unemotional traits are predictive of future psychiatric vulnerability.
Solenogastres (Aplacophora) is a small clade of marine, shell-less worm-molluscs with close to 300 valid species. Their distribution ranges across all oceans, and whereas the vast majority of species has been collected and described from the continental shelf and slope, only few species are known from depths below 4,000 m. Following traditional taxonomy, identification of specimens to species level is complex and time-consuming and requires detailed investigations of morphology and anatomy—often resulting in the exclusion of the clade in biodiversity or biogeographic studies. During the KuramBio expedition (Kuril-Kamchatka Biodiversity Studies) to the abyssal plain of the Northwest Pacific and the Kuril-Kamchatka Trench, 33 solenogaster specimens were sampled from 4,830 m to 5,397 m. Within this study we present an efficient workflow to address solenogaster diversity, even when confronted with a high degree of singletons and minute body sizes, hampering the use of single individuals for multiple morphological and molecular approaches. We combine analyses of external characters and scleritome with molecular barcoding based on a self-designed solenogaster specific set of mitochondrial primers. Overall we were able to delineate at least 19 solenogaster lineages and identify 15 species to family level and beyond. Based on our approach we identified three key lineages from the two regionally most species-rich families (Acanthomeniidae and Pruvotinidae) for deeper taxonomic investigations and describe the novel abyssal species Amboherpia abyssokurilensis sp. nov. (Cavibelonia, Acanthomeniidae) using microanatomical 3D-reconstructions. Our study more than doubles the previous records of solenogaster species from the Northwest Pacific and its marginal seas. Almost all lineages are reported for the first time from the region of the (Northwest) Pacific, vastly expanding distribution ranges of the respective clades. Moreover it doubles the number of Solenogastres collected from abyssal depths on a global scale and underlines the lack of exploratory α-diversity work in the abyssal zone for reliable species estimates in marine biodiversity.

Mit dem Ziel einer Re-Politisierung der Selbstbildung im Sinne einer politischen Ökologie legt Katja Rothe das Spiel als ein Gefüge aus, welches das Subjekt auf eine "umweltliche" Weise herstellt, mit sozialen Formen verbindet und kontextualisiert. Ausgehend von einem Überblick über die Bedeutung des Spiels und der Spieltherapien in der psychologischen Praxis von Hermine Hug-Hellmuth über Anna Freud und Melanie Klein, Margaret Lowenfeld und Dora Kalff und deren Vernachlässigung in der Wissenschaftsgeschichte der Psychologie schlägt Rothe vor, Spiele als Formen und Technologien der "Selbst-Bildung" auszulegen, in denen die Interaktion mit Objekten den Ausgangspunkt von offenen bedeutungsgenerierenden Prozessen bildet. Dabei bezieht sich Rothe, wenn sie von Objekten spricht, auf das Konzept des Übergangsobjekts, das im Zentrum von Winnicotts Theorie des Spiels steht. Das zu einem Ort des Übergangs gewordene Objekt beschreibt sie als jenes Element im Spiel, das es erlaubt, etwas zu finden, was man erfunden habe. Das Spiel wird damit als Versammlungsort beschreibbar, an dem sich Subjekt und Objekt in umweltlicher Weise gegenseitig konstituieren.
Le gouvernement de soi et des autres: Zu Auftrittsverboten für türkische Regierungsmitglieder
(2017)
Die hochproblematische Verfassungsreform in der Türkei führt innerhalb der EU zu ungewöhnlichen Allianzen: In seltener Einmütigkeit wird länderübergreifend von ganz rechts bis weit ins linke politische Spektrum hinein ein Auftrittsverbot für türkische Politiker gefordert. Das gefühlt häufigste Argument bemüht dabei die Souveränität: Man möchte die Kampagne der türkischen Regierung für ihre die Gewaltenteilung gefährdende Verfassungsreform nicht auch noch im eigenen Land haben. In einer pluralistischen Gesellschaft weckt solche Einmütigkeit Zweifel, die sich bei näherem Hinschauen verfestigen – und zwar in juristischer wie politischer Hinsicht.
It seems that the BVerfG has learned a lesson. Yesterday’s referral about the the European Central Bank’s policy of Quantitative Easing (QE) sets a completely different tone. It reads like a modest and balanced plea for judicial dialogue, rather than an indictment. Fifty years after the original event, a new Summer of Love seems to thrive between the highest judicial bodies. It shows no traces of the aplomb with which Karlsruhe presented its stance to Luxembourg three years ago.
The pointed commentary published on Verfassungsblog over the last week—coming from different perspectives and informed from different experiences—shows the potential of such debates. In the case of Greece, they are an important addition to a discourse focusing too much on austerity or debt sustainability.

"Gleichstellung ohne Männer" und "Mann kann nicht Gleichstellungsbeauftragter werden" bzw. "Mann darf nicht Gleichstellungsbeauftragter werden" titeln die Zeitungen zum Urteil des Landesverfassungsgerichts Mecklenburg-Vorpommern vom letzten Dienstag (10. Oktober 2017). Gerügt wird, dass Gleichstellung "nicht nur Frauensache" bzw. kein "reines Frauenthema" sei. Und die Kommentarspalten sind einmal mehr voll wütenden Aufruhrs.
The asymmetric unit of the title compound, C21H28N4O, consists of two unique molecules linked by an O—H⋯N hydrogen bond. The conformation of both C=N bonds is E and the azomethine functional groups lie close to the plane of their associated benzene rings in each of the independent molecules. The dihedral angles between the two benzene rings are 83.14 (4) and 75.45 (4)°. The plane of the one of the N(CH3)2 units is twisted away from the benzene ring by 18.8 (2)°, indicating loss of conjugation between the lone electron pair and the benzene ring. In the crystal structure, O—H⋯N hydrogen bonds together with C—H⋯O hydrogen bonds link neighbouring supramolecular dimers into a three-dimensional network.
Geschlechtliche Vielfalt ist auch rechtlich mehr als Zweigeschlechtlichkeit, so das BVerfG in seinem Beschluss zur "dritten Option": Das aktuelle Personenstandsrecht ist verfassungswidrig, soweit es dazu zwingt, das Geschlecht zu registrieren, aber keinen anderen positiven Geschlechtseintrag als weiblich oder männlich zulässt. Ebenso revolutionär wie das Ergebnis ist auch die Begründung: Der Senat ordnet den Schutz der Geschlechtsidentität erstmals nicht nur dem allgemeinen Persönlichkeitsrecht, Art. 2 Abs. 1 iVm Art. 1 Abs. 1 GG zu, sondern auch dem Diskriminierungsverbot des Art. 3 Abs. 3 S. 1 GG. Im Rahmen des Symposiums wirft dieser Beitrag einen Blick auf die freiheitsrechtliche Begründung und arbeitet heraus, warum es wichtig ist, Freiheitsrechte und Gleichheitsrechte nicht isoliert voneinander zu betrachten.
Wozu VB?

Die eifrigste Bestrebung der Kinder besteht darin, so hat es zumindest Sigmund Freud einmal behauptet, "zu erfahren, was die Eltern miteinander tun, woraus dann die Kinder werden." Was treibt die Kinder in die Welt? Haben die Kinder Juristen als Eltern, dann dürften sie bald eher nach den Gründen als nach dem Treiben fragen.
Die gleichgeschlechtliche Ehe wurde vom Gesetzgeber endlich anerkannt, auch das Verfassungsgericht wird dagegen nichts mehr unternehmen können, das hoffe ich zumindest. Wer seine Zeichen und Gesetze dennoch exklusiv halten will, sollte darum darüber nachdenken, auf Alternativbegriffe zur Ehe umzusteigen.
Die Verkleidung des Richters und die Verkleidung der Muslima sind ähnlich, weil sie beide aus einer Abschirmung rühren, die auf gleiche Weise dogmatisch besetzt ist. Auch wenn, zumindest in der deutschen Übersetzung des Koran, mit der Bedeckung der Haare die Keuschheit, Sittsamkeit oder Schamhaftigkeit der Frau und mit der Verkleidung des Richters seine Neutralität symbolisiert oder umgesetzt werden soll, gibt es doch eine Entsprechung, und die liegt in der Abschirmung. Wenn man hijab mit Absperrung oder Verhüllung übersetzt, wie das einige vorschlagen, dann tragen Richter auch einen hijab.
Wenn Rechtstexte auf literarische Texte treffen, dann treffen Wahrheitsformen aufeinander. Es treffen unterschiedliche Weisen, Wahrheit zu produzieren, aufeinander. Zu den zahlreichen Unterschieden gehören, historisch bedingt, unterschiedliche Stile, die sich um die Objektivierung und "Subjektivierung" der Aussagen bilden. Das fängt bei den banalen "wir" und "man" rechtswissenschaftlicher Texte an, geht über allgemein gehaltene, enthistorisierende und systematisierende Definitionen bis zu einem Fussnotenapparat, der in manchen Rechtstexten beinahe jede Aussage als nachweisbare Aussage absichern soll. Die Rechtswissenschaft, zumal die deutsche, pflegt bei ihren Wahrheitsformen objektivierende Stile, die Literaturwissenschaft tut das nicht, nicht in dem Maße, sie lässt das Subjekt stärker in die Aussage einbrechen. Die Lage zwischen diesen beiden Disziplinen ist allerdings kompliziert, weil wiederum das Recht eine wirksame Subjektivierungsinstanz ist, die eben die Instrumente zur Verfügung stellt, um Aussagen an Subjekte zu binden. Sie hat die Unterschrift und den Urheber erfunden. In dieser Lage kann man also nicht einfach das Subjektive gegen das Objektive ausspielen. Von Anfang aber über das Zusammentreffen von Literatur und Recht in objektivierenden Stilen zu schreiben, schafft eine asymmetrische Ausgangslage, die ich gerne zugunsten einer symmetrischen Ausgangslage umgehen möchte – soweit das möglich ist. ...
This paper analyses economic power, state power and ideological power in the age of Donald Trump with the help of critical theory. It applies the critical theory approaches of thinkers such as Franz Neumann, Theodor W. Adorno and Erich Fromm. It analyses changes of US capitalism that have together with political anxiety and demagoguery brought about the rise of Donald Trump. This article draws attention to the importance of state theory for understanding Trump and the changes of politics that his rule may bring about. It is in this context important to see the complexity of the state, including the dynamic relationship between the state and the economy, the state and citizens, intra-state relations, inter-state relations, semiotic representations of and by the state, and ideology. Trumpism and its potential impacts are theorised along these dimensions. The ideology of Trump (Trumpology) has played an important role not just in his business and brand strategies, but also in his political rise. The (pseudo-)critical mainstream media have helped making Trump and Trumpology by providing platforms for populist spectacles that sell as news and attract audiences. By Trump making news in the media, the media make Trump. An empirical analysis of Trump’s rhetoric and the elimination discourses in his NBC show The Apprentice underpins the analysis of Trumpology. The combination of Trump’s actual power and Trump as spectacle, showman and brand makes his government’s concrete policies fairly unpredictable. An important question that arises is what social scientists’ role should be in the conjuncture that the world is experiencing.

In Gaggenau hat man originär sicherheitsrechtlich argumentiert: viel zu viele Leute, viel zu kleiner Parkplatz, Chaos vorprogrammiert. Ähnliches nun in Köln: zu großer Aufwand, zu kurzfristig, Chaos vorprogrammiert. Nehmen wir einmal an, es seien im Einzelfall tragfähige Begründungen gewesen. Dann stellt sich zugleich die Frage: Was kann man tun, wenn man den Auftritt eines ausländischen Vertreters untersagen will, obwohl der Parkplatz groß genug und die Polizei ausreichend gegen Ausschreitungen gewappnet ist? ...

Autophagy in cancer therapy
(2017)
Autophagy represents a catabolic program involved in the degradation of cellular components via lysosomes. It serves to mitigate cellular stress and to provide metabolic precursors especially upon starvation. Thereby, autophagy can support the survival of cancer cells. In addition, there is now convincing evidence showing that under certain conditions autophagy can also foster cell death. This dual function of autophagy is also relevant upon anticancer treatment, as many chemotherapeutic agents engage autophagy. A better understanding of the molecular mechanisms that are critical for mediating autophagic cell death in cancer cells will be instrumental to selectively interfere with this cellular program in order to increase the cancer cell’s response to cytotoxic drugs. This review illustrates how anticancer drug-induced autophagy is involved in mediating cell death.
The marketing materials of remote eye-trackers suggest that data quality is invariant to the position and orientation of the participant as long as the eyes of the participant are within the eye-tracker’s headbox, the area where tracking is possible. As such, remote eye-trackers are marketed as allowing the reliable recording of gaze from participant groups that cannot be restrained, such as infants, schoolchildren and patients with muscular or brain disorders. Practical experience and previous research, however, tells us that eye-tracking data quality, e.g. the accuracy of the recorded gaze position and the amount of data loss, deteriorates (compared to well-trained participants in chinrests) when the participant is unrestrained and assumes a non-optimal pose in front of the eye-tracker. How then can researchers working with unrestrained participants choose an eye-tracker? Here we investigated the performance of five popular remote eye-trackers from EyeTribe, SMI, SR Research, and Tobii in a series of tasks where participants took on non-optimal poses. We report that the tested systems varied in the amount of data loss and systematic offsets observed during our tasks. The EyeLink and EyeTribe in particular had large problems. Furthermore, the Tobii eye-trackers reported data for two eyes when only one eye was visible to the eye-tracker. This study provides practical insight into how popular remote eye-trackers perform when recording from unrestrained participants. It furthermore provides a testing method for evaluating whether a tracker is suitable for studying a certain target population, and that manufacturers can use during the development of new eye-trackers.
We study the correlation between the distributions of the net-charge, net-kaon, net-baryon and net-proton number at hadronization and after the final hadronic decoupling by simulating ultra relativistic heavy ion collisions with the hybrid version of the ultrarelativistic quantum molecular dynamics (UrQMD) model. We find that due to the hadronic rescattering these distributions are not strongly correlated. The calculated change of the correlation, during the hadronic expansion stage, does not support the recent paradigm, namely that the measured final moments of the experimentally observed distributions do give directly the values of those distributions at earlier times, when the system had been closer to the QCD crossover.
Distillation of scalar exchange by coherent hypernucleus production in antiproton–nucleus collisions
(2017)
The total and angular differential cross sections of the coherent process p¯ + A Z → A (Z − 1) + ¯ are evaluated at the beam momenta 1.5 ÷ 20 GeV/c within the meson exchange model with bound proton and -hyperon wave functions. It is shown that the shape of the beam momentum dependence of the hypernucleus production cross sections with various discrete states is strongly sensitive to the presence of the scalar κ-meson exchange in the p p¯ → ¯ amplitude. This can be used as a clean test of the exchange by scalar π K correlation in coherent p A¯ reactions.
What is the magnetic field distribution for the equation of state of magnetized neutron stars?
(2017)
In this Letter, we report a realistic calculation of the magnetic field profile for the equation of state inside strongly magnetized neutron stars. Unlike previous estimates, which are widely used in the literature, we find that magnetic fields increase relatively slowly with increasing baryon chemical potential (or baryon density) of magnetized matter. More precisely, the increase is polynomial instead of exponential, as previously assumed. Through the analysis of several different realistic models for the microscopic description of stellar matter (including hadronic, hybrid and quark models) combined with general relativistic solutions endowed with a poloidal magnetic field obtained by solving Einstein–Maxwell's field equations in a self-consistent way, we generate a phenomenological fit for the magnetic field distribution in the stellar polar direction to be used as input in microscopic calculations.
Unparticle Casimir effect
(2017)
In this paper we present the un-Casimir effect, namely the study of the Casimir energy in the presence of an unparticle component in addition to the electromagnetic field contribution. The distinctive feature of the un-Casimir effect is a fractalization of metallic plates. This result emerges through a new dependence of the Casimir energy on the plate separation that scales with a continuous power controlled by the unparticle dimension. As long as the perfect conductor approximation is valid, we find bounds on the unparticle scale that are independent of the effective coupling constant between the scale invariant sector and ordinary matter. We find regions of the parameter space such that for plate distances around 5 μm and larger the un-Casimir bound wins over the other bounds.
Motivated by a recent finding of an exact solution of the relativistic Boltzmann equation in a Friedmann–Robertson–Walker spacetime, we implement this metric into the newly developed transport approach Simulating Many Accelerated Strongly-interacting Hadrons (SMASH). We study the numerical solution of the transport equation and compare it to this exact solution for massless particles. We also compare a different initial condition, for which the transport equation can be independently solved numerically. Very nice agreement is observed in both cases. Having passed these checks for the SMASH code, we study a gas of massive particles within the same spacetime, where the particle decoupling is forced by the Hubble expansion. In this simple scenario we present an analysis of the freeze-out times, as function of the masses and cross sections of the particles. The results might be of interest for their potential application to relativistic heavy-ion collisions, for the characterization of the freeze-out process in terms of hadron properties.
The first principle lattice QCD methods allow to calculate the thermodynamic observables at finite temperature and imaginary chemical potential. These can be compared to the predictions of various phenomenological models. We argue that Fourier coefficients with respect to imaginary baryochemical potential are sensitive to modeling of baryonic interactions. As a first application of this sensitivity, we consider the hadron resonance gas (HRG) model with repulsive baryonic interactions, which are modeled by means of the excluded volume correction. The Fourier coefficients of the imaginary part of the netbaryon density at imaginary baryochemical potential – corresponding to the fugacity or virial expansion at real chemical potential – are calculated within this model, and compared with the Nt = 12 lattice data. The lattice QCD behavior of the first four Fourier coefficients up to T 185 MeV is described fairly well by an interacting HRG with a single baryon–baryon eigenvolume interaction parameter b 1 fm3, while the available lattice data on the difference χB 2 − χB 4 of baryon number susceptibilities is reproduced up to T 175 MeV.
We study the charmonium coherent photoproduction and hadroproduction consistently with modifications from both cold and hot nuclear matters. The strong electromagnetic fields from fast moving nucleus interact with the other target nucleus, producing abundant charmonium in the extremely low transverse momentum region pT<0.1 GeV/c. This results in significative enhancement of J/ψ nuclear modification factor in semi-central and peripheral collisions. In the middle pT region such as pT<3∼5 GeV/c, J/ψ final yield is dominated by the combination process of single charm and anti-charm quarks moving in the deconfined matter, c+c¯→J/ψ+g. In the higher pT region, J/ψ production are mainly from parton initial hard scatterings at the beginning of nucleus–nucleus collisions and decay of B hadrons. We include all of these production mechanisms and explain the experimental data well in different colliding centralities and transverse momentum regions.
Risk culture during the last 2000 years - from an aleatory society to the illusion of risk control
(2017)
The culture of risk is 2000 years old, although the term “risk” developed much later. The culture of merchants making decisions under uncertainty and taking the individual responsibility for the uncertain future started with the Roman “Aleatory Society”, continued with medieval sea merchants, who made business “ad risicum et fortunam”, and sustained to the culture of entrepreneurs in times of industrialisation and dynamic economic changes in the 18th and 19th century. For all long-term commercial relationships, the culture of honourable merchants with personal decision-making and individual responsibility worked well. The successful development of sciences, statistics and engineering within the last 100 years led to the conjecture that men can “construct” an economical system with a pre-defined “clockwork” behaviour. Since probability distributions could be calculated ex-post, an illusion to control risk ex-ante became a pattern in business and banking. Based on the recent experiences with the financial crisis, a “risk culture” should understand that human “Strength of Knowledge” is limited and the “unknown unknown” can materialise. As all decisions and all commercial agreements are made under uncertainty, the culture of honourable merchants is key to achieve trust in long-term economic relations with individual responsibility, flexibility to adapt and resilience against the unknown.
Background: Computed tomography of the head (HCT) is a widely used diagnostic tool, especially for emergency and trauma patients. However, the diagnostic yield and outcomes of HCT for patients on medical intensive care units (MICUs) are largely unknown.
Methods: We retrospectively evaluated all head CTs from patients admitted to a single-center MICU during a 5-year period for CT indications, diagnostic yield, and therapeutic consequences. Uni- and multivariate analyses for the evaluation of risk factors for positive head CT were conducted.
Results: Six hundred ninety (18.8%) of all patients during a 5-year period underwent HCT; 78.7% had negative CT results, while 21.3% of all patients had at least 1 new pathological finding. The main indication for acquiring CT scan of the head was an altered mental state (AMS) in 23.5%, followed by a new focal neurology in 20.7% and an inadequate wake up after stopping sedation in 14.9% of all patients. The most common new finding was intracerebral bleeding in 6.4%. In 6.7%, the CT scan itself led to a change of therapy of any kind. Admission after resuscitation or a new focal neurology were independent predictors of a positive CT. Psychic alteration and AMS were both independent predictors of a higher chance of a negative head CT. Positive HCT during MICU is an independent predictor of lower survival.
Conclusions: New onset of focal neurologic deficit seems to be a good predictor for a positive CT, while AMS and psychic alterations seem to be very poor predictors. A positive head CT is an independent predictor of death for MICU patients.
Oxygenation-sensitive spin relaxation time T2′ and relaxation rate R2′ (1/T2′) are presumed to be markers of the cerebral oxygen extraction fraction (OEF) in acute ischemic stroke. In this study, we investigate the relationship of T2′/R2′ with dynamic susceptibility contrast-based relative cerebral blood flow (rCBF) in acute ischemic stroke to assess their plausibility as surrogate markers of the ischemic penumbra. Twenty-one consecutive patients with internal carotid artery and/or middle cerebral artery occlusion were studied at 3.0 T. A physiological model of the cerebral vasculature (VM) was used to process PWI raw data in addition to a conventional deconvolution technique. T2′, R2′, and rCBF values were extracted from the ischemic core and hypoperfused areas. Within hypoperfused tissue, no correlation was found between deconvolved rCBF and T2′ (r = −0.05, p = 0.788), or R2′ (r = 0.039, p = 0.836). In contrast, we found a strong positive correlation with T2′ (r = 0.444, p = 0.006) and negative correlation with R2′ (r = −0.494, p = 0.0025) for rCBFVM, indicating increasing OEF with decreasing CBF and that rCBF based on the vascular model may be more closely related to metabolic disturbances. Further research to refine and validate these techniques may enable their use as MRI-based surrogate markers of the ischemic penumbra for selecting stroke patients for interventional treatment strategies.
The Karl Schwarzschild Meeting 2017 (KSM2017) has been the third instalment of the conference dedicated to the great Frankfurter scientist, who derived the first black hole solution of Einstein's equations about 100 years ago.
The event has been a 5 day meeting in the field of black holes, AdS/CFT correspondence and gravitational physics. Like the two previous instalments, the conference continued to attract a stellar ensemble of participants from the world's most renowned institutions. The core of the meeting has been a series of invited talks from eminent experts (keynote speakers) as well as the presence of plenary research talks by students and junior speakers.

Die Straße als Transit- und Abstellraum für Automobile ist kein Naturgesetz. Mit Michel de Certeau lässt sie sich als historisches Produkt einer Strategie verstehen, die sich in einem immerwährenden Konflikt durchsetzt. Ziel dieses Beitrags ist es, die Straße als Ort des Automobils zu denaturalisieren, um das konflikthafte Spannungsverhältnis zwischen den als rezessiv antizipierten Bewegungen des Zufußgehens und jenen dominanten automobilen Bewegungen sichtbar zu machen. Mithilfe einer interventionistischen Flächenprojektion von Fußwegen – einem selbstgemalten Zebrastreifen aus Kreide – wird anhand eines Fallbeispiels aus Frankfurt am Main aufgezeigt, wie sich die alltäglich konflikthafte Aushandlung von Straßenräumen durch Planung materialisieren und somit in die Konzeption von Straße integrieren lässt.
Advances in information and communication technologies enable more decentralized and individualized mechanisms for coordination and for managing societal complexity. This has important consequences for the role of conditionality and the idea of individual responsibility in two seemingly unrelated policy areas. First, the changing information infrastructure enables an extension of conditionality in the area of welfare through greater activation, enhanced self-management, and a personalization of risks. Second, conditionality and personal responsibility also form an important ideational template and a legitimatory basis for facilitating value creation that is based on data as a raw material. This argument is illustrated looking at the trajectories of the digital strategies in the United Kingdom and Germany. In both cases, data protection is depicted as a question of individual responsibility and tied to certain forms of individual conduct.
