The placozoan Trichoplax adhaerens is a tiny hairy plate and more simply organized than any other living metazoan. After its original description by F.E. Schulze in 1883, it attracted attention as a potential model for the ancestral state of metazoan organization, the “Urmetazoon”. Trichoplax lacks any kind of symmetry, organs, nerve cells, muscle cells, basal lamina, and extracellular matrix. Furthermore, the placozoan genome is the smallest (not secondarily reduced) genome of all metazoan genomes. It harbors a remarkably rich diversity of (...) genes and has been considered the best living surrogate for a metazoan ancestor genome. The phylum Placozoa presently harbors three formally described species, while several dozen “cryptic” species are yet awaiting their description. The phylogenetic position of placozoans has recently become a contested arena for modern phylogenetic analyses and view‐driven claims. Trichoplax offers unique prospects for understanding the minimal requirements of metazoan animal organization and their corresponding malfunctions. (shrink)

The placozoan Trichoplax adhaerens has been bridging gaps between research disciplines like no other animal. As outlined in part 1, placozoans have been subject of hot evolutionary debates and placozoans have challenged some fundamental evolutionary concepts. Here in part 2 we discuss the exceptional genetics of the phylum Placozoa and point out some challenging model system applications for the best known species, Trichoplax adhaerens.

In this article, we develop the concept of Transparency by Design that serves as practical guidance in helping promote the beneficial functions of transparency while mitigating its challenges in automated-decision making environments. With the rise of artificial intelligence and the ability of AI systems to make automated and self-learned decisions, a call for transparency of how such systems reach decisions has echoed within academic and policy circles. The term transparency, however, relates to multiple concepts, fulfills many functions, and holds different (...) promises that struggle to be realized in concrete applications. Indeed, the complexity of transparency for ADM shows tension between transparency as a normative ideal and its translation to practical application. To address this tension, we first conduct a review of transparency, analyzing its challenges and limitations concerning automated decision-making practices. We then look at the lessons learned from the development of Privacy by Design, as a basis for developing the Transparency by Design principles. Finally, we propose a set of nine principles to cover relevant contextual, technical, informational, and stakeholder-sensitive considerations. Transparency by Design is a model that helps organizations design transparent AI systems, by integrating these principles in a step-by-step manner and as an ex-ante value, not as an afterthought.

Die begriffliche Unterscheidung von Natur und Kultur sowie die Deutung von Kultur als einer zweiten Natur des Menschen sind von systematischer Bedeutung für die Kulturtheorie Georg Simmels. Um den Nebensinn der zweiten Natur als einer bloßen Gewohnheit, die man auch ablegen könnte, nicht zu evozieren, verwendet Simmel selbst den Ausdruck zweite Natur nicht, bewegt sich aber in einer bestimmten Theorietradition, die diesen auf Cicero zurückgehenden Ausdruck programmatisch adaptiert. Von einer Theorie des objektiven Geistes in der Nachfolge von Moritz Lazarus ausgehend, (...) entwickelt Simmel eine Kulturphilosophie, in deren Zentrum die Frage nach dem Verhältnis zwischen dem individuellen Lebensvollzug des Einzelnen und den ihn umgebenden und herausfordernden kulturellen Objektivationen steht.

Poetisierende Musikbeschreibungen werden von der Wissenschaft, von Musikern und Konzertbesuchern heute mehr belächelt als ernst genommen. Durch das Ansprechen von Einbildungskraft und Gefühl haben sie aber eine Unmittelbarkeit, die der kompositionstechnischen Analyse in der Regel fehlt. Die Wurzeln einer metaphorischen Musikbeschreibung um die Wende zum 19. Jahrhundert sind dabei gleichermaßen historisch wie systematisch zu fassen. Zahlreiche Zitate aus den Fachzeitschriften bis zur Jahrhundertmitte dokumentieren die Herausbildung eines festumrissenen Bildervorrats, um musikalische Eindrücke zur Sprache zu bringen. Der kreative Umgang mit Beschreibungskonventionen (...) ist für die Musikkritiken von E.T.A. Hoffmann, Adolf Bernhard Marx, Ludwig Rellstab und vor allem Robert Schumann kennzeichnend. (shrink)

What constitutes our number concept? What makes it possible for us to employ numbers the way we do; which mental faculties contribute to our grasp of numbers? What do we share with other species, and what is specific to humans? How does our language faculty come into the picture? This 2003 book addresses these questions and discusses the relationship between numerical thinking and the human language faculty, providing psychological, linguistic and philosophical perspectives on number, its evolution and its development in (...) children. Heike Wiese argues that language as a human faculty plays a crucial role in the emergence of systematic numerical thinking. She characterises number sequences as powerful and highly flexible mental tools that are unique to humans and shows that it is language that enables us to go beyond the perception of numerosity and to develop such mental tools.

The article explores the underlying reasons for patients’ self‐perception of being a burden (SPB) in family settings, including its impact on relationships when wishes to die (WTD) are expressed. In a prospective, interview‐based study of WTD in patients with advanced cancer and non‐cancer disease (organ failure, degenerative neurological disease, and frailty) SPB was an important emerging theme. In a sub‐analysis we examined (a) the facets of SPB, (b) correlations between SPB and WTD, and (c) SPB as a relational phenomenon. We (...) analyzed 248 interviews with 62 patients, their family caregivers, and professionals using grounded theory and interpretive phenomenological analysis. SPB appeared as important empathic concern in care situations. Patients expressed many sorts of concerns for others, but also perceived an altered self‐understanding that did not meet mutual expectations within relationships. In SPB associated with WTD three constellations were found: (a) WTD to unburden others; (b) patients decided against hastening death to prevent being a further burden to others (in these cases, the SPB counteracted the wish to die); and (c) both wishes for and against dying were sustained by SPB. These patients often felt paralyzed and suffered deeply. Family caregivers felt emotionally touched by SPB and tried to unburden patients by caring and compassion. We concluded that the impact of SPB on a WTD and the various meanings the facets of SPB have in balancing relationships need to be worked out individually. An early palliative and narrative approach is warranted. (shrink)

We argue for a perspective on bilingual heritage speakers as native speakers of both their languages and present results from a large-scale, cross-linguistic study that took such a perspective and approached bilinguals and monolinguals on equal grounds. We targeted comparable language use in bilingual and monolingual speakers, crucially covering broader repertoires than just formal language. A main database was the open-access RUEG corpus, which covers comparable informal vs. formal and spoken vs. written productions by adolescent and adult bilinguals with heritage-Greek, (...) -Russian, and -Turkish in Germany and the United States and with heritage-German in the United States, and matching data from monolinguals in Germany, the United States, Greece, Russia, and Turkey. Our main results lie in three areas. We found non-canonical patterns not only in bilingual, but also in monolingual speakers, including patterns that have so far been considered absent from native grammars, in domains of morphology, syntax, intonation, and pragmatics. We found a degree of lexical and morphosyntactic inter-speaker variability in monolinguals that was sometimes higher than that of bilinguals, further challenging the model of the streamlined native speaker. In majority language use, non-canonical patterns were dominant in spoken and/or informal registers, and this was true for monolinguals and bilinguals. In some cases, bilingual speakers were leading quantitatively. In heritage settings where the language was not part of formal schooling, we found tendencies of register leveling, presumably due to the fact that speakers had limited access to formal registers of the heritage language. Our findings thus indicate possible quantitative differences and different register distributions rather than distinct grammatical patterns in bilingual and monolingual speakers. This supports the integration of heritage speakers into the native-speaker continuum. Approaching heritage speakers from this perspective helps us to better understand the empirical data and can shed light on language variation and change in native grammars. Furthermore, our findings for monolinguals lead us to reconsider the state-of-the art on majority languages, given recurring evidence for non-canonical patterns that deviate from what has been assumed in the literature so far, and might have been attributed to bilingualism had we not included informal and spoken registers in monolinguals and bilinguals alike.

The article takes Helmuth Plessner’s Political Anthropology from 1931 as a postfoundationalist theory of society avant la lettre - which is very similar to the later works of Claude Lefort, Ernesto Laclau, and Chantal Mouffe. Or, the article takes Plessner’s essay as an ‘ontology’ of the Political. After introducing remarks on the historical debates, in which Plessner aimed to intervene, his theory of the Political is reconstructed, within the three categories of ‘unfathomability’, of the constitutive outside, and of the vulnerability (...) of the human body. In a third and last step, Plessner’s most central and most problematic category for the Political - the ‘popular existence’ - is discussed: The ‘people’ is made visible as being a key notion of postfoundational theories of modern democracy, for it is - beneath the ‘Individual’ - one of the imaginary foundations, one of the foundational outsides of a democratically instituted collective.

Drawing on data from a comparative ethnographic study on media usage in transnational families, this paper contributes to a reappraisal of polymedia theory. Two main theoretical assumptions are reconsidered. First, it is demonstrated why the equal availability assumption has to be revised in light of the complex interactions between the corporeal, communicative and social mobilities which together constitute transnational migration. Second, it is argued that the techno-socially accomplished co-presence in transnational families depends more on the creative appropriation and combination of (...) different media channels and communication forms than on the choice between them. In order to empirically investigate the specific needs for, and forms of co-presence in families, the concept of ‘registers of presence’ is proposed. It allows us to understand in detail in what ways and in which constellations transnational families create togetherness with the help of communication technologies. (shrink)

Despite decades of management and conservation efforts, we have seen only limited success in rebuilding marine life and restoring ocean ecosystems from human-inflicted damage on a global scale. I suggest that we need to harness both our emotional and rational sides to create a more powerful movement to heal the ocean and rebuild its abundance and diversity. Love and compassion fuel our desire and urge for change and provide a compass that can guide our actions. Science and knowledge provide ways (...) for collecting and interpreting data and information that can enhance our understanding and support our decisions and actions. Combining our emotional and rational sides can inspire our thinking and transform our actions in new, creative ways. In order to affect wide-ranging and long-lasting change, love and knowledge need to work together to transform our collective relationship with the ocean. (shrink)

Nachdem der Zusammenhang zwischen Sprache und Emotion in der Linguistik lange Zeit vernachlässigt wurde, erhält diese Frage seit etwa 25 Jahren so hohe Aufmerksamkeit, dass von einem 'emotional turn' gesprochen werden kann. Der vorliegende Band dient als Zusammenfassung des aktuellen Forschungsstandes zu diesem komplexen Thema. Berücksichtigt werden Erkenntnisse aus verschiedenen Teildisziplinen, z.B. Semiotik, Lexikologie, Pragmatik, Kognitive Linguistik und Textlinguistik. Im methodischen Teil wird gezeigt, wie eine emotionslinguistische Analyse emotive Strukturen in Texten offenlegen kann, wobei die vorgeschlagene Methode leicht an verschiedene (...) Fragestellungen angepasst werden kann. Die empirische Überprüfung ergibt einen Vergleich von drei sehr unterschiedlichen Textkorpora: Untersucht werden Briefe von Franz Kafka als Beispiel für einen Individualstil, Nachrichtenartikel von verschiedenen Online-Plattformen als Beispiel für Medientexte und die Kommunikationsform Twitter als Beispiel für Online-Kommunikation. Forschende, Lehrende und Studierende finden hier sowohl einen umfassenden Überblick über theoretische Grundlagen als auch Anregungen für die Anwendung in der eigenen Forschung und Lehre. (shrink)

The respiration of oxygen, while essential to aerobic organisms for the generation of energy, leads to the formation of reactive oxygen intermediates (ROIs) as harmful byproducts. ROIs damage nucleic acids, lipids and proteins. Therefore, protective mechanisms against elevated intracellular ROI levels, referred to as oxidative stress, have evolved. These include the activation of transcription factors which elevate the expression of protective enzymes. Eukaryotic cells have also evolved the ability to specifically generate ROIs are used as second messengers to activate gene (...) expression. Here we will discuss both prokaryotic and eukaryotic transcription factors that respond to ROIs. In addition, transcription factors will be described that are activated by either exposure to antioxidants, which reduce the intracellular ROI concentration, or by hypoxia, the absence of oxygen.

This paper provides an introduction to ethical issues arising in children's research that takes place in school-settings. It addresses three main areas of ethical concern: the informed consent process, confidentiality, and harm and benefit. Informed consent in school settings is characterized by the involvement of multiple stakeholders, including not just researchers, parents and individual children but also school principals, teachers and the children's peer group. The added complexity of the setting has implications for the management of the informed consent process, (...) including the decision at what point and in which manner each stakeholder group needs to be involved in the process. The presence and divergent roles of these multiple stakeholders in the school setting also have implications for addressing issues of confidentiality, especially due to the group setting in which participants take part in the research and role expectations within school settings. Harm and benefit in school-based research are of a non-physical nature; relevant areas of concern relate primarily to the potential for psychological and social harm, realistic presentation of likely benefits from research and the issue of rewards for research participation.

It is consistent that each union of many families in the Baire space which are not finitely dominating is not dominating. In particular, it is consistent that for each nonprincipal ultrafilter , the cofinality of the reduced ultrapower is greater than . The model is constructed by oracle chain condition forcing, to which we give a self-contained introduction.

The volume provides an overview of the origins of early medieval aristocratic literature. Although there are regional, linguistic and formal differences, one can observe a number of similarities. Oral literature disseminates a range of themes that are shared by narratives in most parts of the continent. The authors address these similarities in Roman, Nordic, Anglo-Saxon and Germanic literature and use different methodologies to explain them.

tRNA nucleotidyltransferase adds the invariant CCA‐terminus to the tRNA 3′‐end, a central step in tRNA maturation. This CCA‐adding enzyme is a specialized RNA polymerase that synthesizes the CCA sequence at high fidelity in all kingdoms of life. Recently, an additional function of this enzyme was identified, where it generates a specific degradation tag on structurally unstable tRNAs. This tag consists of an additional repeat of the CCA triplet, leading to a 3′‐terminal CCACCA sequence. In order to explain how the enzyme (...) catalyzes this extended polymerization reaction, Kuhn et al. solved a series of co‐crystal structures of the CCA‐adding enzyme from Archaeoglobus fulgidus in complex with different tRNA substrates. They show that the enzyme forces a bound unstable tRNA to refold the acceptor stem for a second round of CCA‐addition, while stable transcripts are robust enough to resist this isomerization. In this review, we discuss how the CCA‐adding enzyme uses a simple yet very elegant way to scrutinize its substrates for sufficient structural stability and, consequently, functionality. (shrink)

Zeitgleich mit Cassirers erstem Band der „Philosophie der symbolischen Formen“ erscheint mit der „Einheit der Sinne. Grundlinien einer Ästhesiologie des Geistes“ das frühe, weithin unbemerkt gebliebene Hauptwerk Helmuth Plessners. Um Plessners schwieriges Werk in seiner Originalität und darin in seiner Aktualität sichtbar zu machen, werden beide Werke als kulturphilosophische ‚Parallelaktion‘ rekonstruiert, der es darum geht, systematisch die Spannweite der menschlichen Symbolwelten zwischen Mythos bzw. Kunst auf der einen, Wissenschaft auf der anderen Seite zu erschließen.

Long description: Welche Triebkräfte und Möglichkeitsräume gesellschaftlicher Veränderung verbinden sich mit den Dynamiken des modernen Kapitalismus? Tino Heims breit angelegte Studie zielt auf die Überwindung analytischer Defizite der jüngsten Kapitalismusdebatte. In einer theoriesystematischen Verknüpfung und gegenstandsbezogenen Weiterentwicklung der Analyseraster von Marx, Foucault und Bourdieu - die auch als Kritik dominanter Rezeptionslinien antritt - werden zentrale kapitalistische Funktionslogiken und Krisendynamiken ebenso prägnant analysiert wie historische Transformationen konkreter Modi kapitalistischer Vergesellschaftung. Damit wird zugleich ein Beitrag zur Neubestimmung einer analytisch-kritischen Sozialwissenschaft jenseits normativer (...) Sozialkritik geleistet. (shrink)
