Plastids and mitochondria arose through endosymbiotic acquisition of formerly free-living bacteria. During more than a billion years of subsequent concerted evolution, the three genomes of plant cells have undergone dramatic structural changes to optimize the expression of the compartmentalized genetic material and to fine-tune the communication between the nucleus and the organelles. The chimeric composition of many multiprotein complexes in plastids and mitochondria (one part of the subunits being nuclear encoded and another one being encoded in the organellar genome) provides (...) a paradigm for co-evolution at the cellular level. In this paper, we discuss the co-evolution of nuclear and organellar genomes in the context of environmental adaptation in species and populations. We highlight emerging genetic model systems and new experimental approaches that are particularly suitable to elucidate the molecular basis of co-adaptation processes and describe how nuclear-cytoplasmic co-evolution can cause genetic incompatibilities that contribute to the establishment of hybridization barriers, ultimately leading to the formation of new species.

Why the DNA‐containing organelles, chloroplasts, and mitochondria, are inherited maternally is a long standing and unsolved question. However, recent years have seen a paradigm shift, in that the absoluteness of uniparental inheritance is increasingly questioned. Here, we review the field and propose a unifying model for organelle inheritance. We argue that the predominance of the maternal mode is a result of higher mutational load in the paternal gamete. Uniparental inheritance evolved from relaxed organelle inheritance patterns because it avoids the spread (...) of selfish cytoplasmic elements. However, on evolutionary timescales, uniparentally inherited organelles are susceptible to mutational meltdown (Muller's ratchet). To prevent this, fall‐back to relaxed inheritance patterns occurs, allowing low levels of sexual organelle recombination. Since sexual organelle recombination is insufficient to mitigate the effects of selfish cytoplasmic elements, various mechanisms for uniparental inheritance then evolve again independently. Organelle inheritance must therefore be seen as an evolutionary unstable trait, with a strong general bias to the uniparental, maternal, mode. (shrink)

Sensory augmentation challenges current societal norms and views of what is conceived as a “normal” human being. Beginning with self reflections of a bodyhacker, the author proposes an extended view onto the human or respectively cyborg body. Based on cognitive theories, it is argumented that we are already mental cyborgs. Our brains plastically restructure themselves in order to meet new requirements of the technological extended human.

A first-person account of some victims of the virus, the author puts faces and circumstances to the tragedy of the Covid-19 pandemic. Told from a chaplain’s point of view, these narratives will take the reader beyond the numbers and ask questions like: What is the cost of keeping families separated at the end of life, and, if patient/family centered care is so central to healthcare these days, why was it immediately discarded? Is potentially saving human lives worth the risk of (...) damaging them beyond repair? (shrink)

The article undertakes a rereading of Nietzsche’s Birth of Tragedy with a focus on its two central achievements – reviving the Dionysus myth and making the origin of tragedy evident – whose mutual interrelatedness has attracted only sparse critical attention to date. Working more as a myth-maker than a theorist, Nietzsche advances a groundbreaking portrayal of the story of Dionysus that allows him to lay bare the origins of tragedy. Simultaneously, his identification of tragedy’s ultimate source suggests a configuration that (...) lends the Dionysus myth new currency. In so doing, Nietzsche conceives the manifest presence of this myth – as well as that of the origins of tragedy – as a specific recombination of the Dionysian and the Apollonian: not as an Apollonian taming or sublimation of the Dionysian, nor yet as dialectical mediation, but rather as the Apollonian’s seizure by the Dionysian, which teeters on the threshold between lurching toward and postponing a new, more comprehensively Dionysian loss of boundaries. In this way, Nietzsche suggests, there is generated a »Schauen und Sehnen über das Schauen hinaus,« a mode of viewing amplified by longing, through which the specific form of the Dionysus myth from the perspective of tragedy and conversely of tragedy from the perspective of myth becomes apparent. The fulfillment of Nietzsche’s vision in dramatic art is here exemplified by Hofmannsthal’s Elektra. (shrink)

The accessibility of art in Germany underwent a fundamental change over the course of the 18th century. Aristocratic collectors opened their doors to the general public, and new museums were dedicated exclusively to art. This development parallels the concurrent development of aesthetics in philosophy and the conception of the autonomy of art. Its theoretical foundation was provided by Kant in his third critique with such completeness that the standards of beauty he worked out emerge as constitutive elements of the art (...) museum. The Romantic movement reinforced the trend in what proved to be an ambivalent way. The general accessibility of art was well suited to its transgression of boundaries, but it necessitated a new, less contingent mode of demarcation between the work of art and the observer. That became an occasion for »Romanticization« of both the artwork and its audience, demonstrated here by August Wilhelm Schlegel’s conversation on art Die Gemählde. It is further elucidated by Friedrich Schlegel’s Nachricht von den Gemählden in Paris and its echo in two texts published by Kleist: The novella Die Heilige Cäcilie oder die Gewalt der Musik and the essay on Caspar David Friedrich’s painting Mönch am Meer that was drafted by Clemens Brentano and Achim von Arnim and radically modified by Kleist.

Technology has expanded genomic research and the complexity of extracted gene-related information. Health-related genomic incidental findings pose new dilemmas for nurse researchers regarding the ethical application of disclosure to participants. Consequently, informed consent specific to incidental findings is recommended. Critical Social Theory is used as a guide in recognition of the changing meaning of informed consent and to serve as a framework to inform nursing of the ethical application of disclosure consent in genomic nursing research practices.

In this paper it is argued that questions in perinatal medicine concerning treatment or non-treatment of severely handicapped children, after or before birth, cannot be answered solely by referring to the general aims and objectives of medical treatment and its specific deontology. Justifications of decisions about treatment and non-treatment need to be placed in a broader context of discussions about social justice and the social significance of medical practice as a whole.

Definition of the problem: Even after the new German legislation about organ donors and transplantation (“information solution”), the question of criteria for distributing the organs is still not solved. The various alternatives to solve this problem face different social acceptance and economic efficiency.Arguments: Medical criteria (e.g. HLA compatibility) and non-medical criteria (e.g. willingness to pay of the patients) are valued on the basis of generally accepted objectives (e.g. equal access to health services or low costs). As an innovative form of (...) organ distribution systems the club solution is introduced. It allows the donor to realise preferences regarding use of the organs.Conclusion: Scoring systems may help to increase the transparency of organ allocation. From an economic point of view medical criteria have to be weighted more than non-medical criteria. (shrink)

In reference to the paradoxical classification of art in Kafka’s Josefine story, religious aspects of the artist’s performances and their effect on the audience are scrutinized. The leading question is to what extent it evokes an allusion to the primal scene of divine revelation, following Stéphane Mosès’ commentary in his readings of the Bible. Josefine’s singing with a “nothing of a voice”, reduced to “the slightest of nullities”, the zero-point of signification, nevertheless affects an experience of presence and community that (...) touches the listeners’ entire being. From the perspective of the artist, her song recitals are manifestations of supreme art of which she claims a soteriological significance in respect of her audience who belongs in Kafka’s portrayal obviously to the Jewish people. Around such a tension between maximal restraint of an utterance (the voice onset of the aleph of the word anokhi/i) and all-encompassing meaning (the name of God and all Commandments whose acceptance is constitutive for the Jewish people) circle the theological exegeses of the Sinai-scene (esp. Ex. 20,1) in the tradition of Rashi and Maimonides, in modernity e.g. of Gershom Scholem in dispute with Walter Benjamin on Kafka. It will be shown that the depicted paradoxes of Josefine’s art performances unfold the mentioned tension as an original literary reflection on revelation and language under the conditions of modernity.

The gap between a firm's "talk" and its "walk" has received significant research attention in the CSR literature: does the firm’s behavior represent “aspirational talk” or just “greenwashing?” We drew on the formative view of communication to explore the question of whether executives’ environmental talk triggers firms to take environmental action. The method we applied was to study executive presentations in less constrained environments where the executives have more discretion. Using 1456 transcripts of executive presentations made by publicly traded firms (...) in polluting industries at broker-hosted conferences, we found that executive utterances on environmental topics in the events were marginally associated with an increase in a firm’s environmental action. In addition, this study appears to show that a presentation style characterized by numeric concreteness moderates that impact, while a presentation style that instead emphasizes narrative concreteness does not.

We generalize the nonlinear one-dimensional equation of a fluid layer for any depth and length as an infinite-order differential equation for the steady waves. This equation can be written as a q-differential one, with its general solution written as a power series expansion with coefficients satisfying a nonlinear recurrence relation. In the limit of long and shallow water (shallow channels) we reobtain the well-known KdV equation together with its single-soliton solution.

We introduce a smooth mapping of some discrete space-time symmetries into quasi-continuous ones. Such transformations are related with q-deformations of the dilations of the Euclidean space and with the noncommutative space. We work out two examples of Hamiltonian invariance under such symmetries. The Schrödinger equation for a free particle is investigated in such a noncommutative plane and a connection with anyonic statistics is found.

Health equity can be defined as the absence of disadvantage to individuals and communities in health outcomes, access to health care, and quality of health care regardless of one’s race, gender, nationality, age, ethnicity, religion, and socioeconomic status. Health equity concerns those disparities in public health that can be traced to unequal, systemic economic, and social conditions. Despite significant improvements in the health of the overall population, health inequities in America persist. Racial and ethnic minorities continue to experience higher rates (...) of morbidity and mortality than non-minorities across a range of health issues. For example, African-American children with asthma have a seven times greater mortality rate than Non-Hispanic white children with the illness. While cancer is the second leading cause of death among all populations in the U.S., ethnic minorities are especially burdened with the disease. (shrink)

Constructive Realism, an increasingly discussed philosophy of science founded by the Viennese philosopher of science Fritz G. Wallner, is the core issue of the texts gathered in this volume. The authors either discuss the constructive-realistic view philosophically or present their research interpreted by the constructive-realistic doctrine. Constructive Realism inspires philosophy as well as natural science and humanities. This volume proves this inspiring feature of Constructive Realism. All texts are written by colleagues, friends and scholars of Fritz G. Wallner to honour (...) his 60th birthday. (shrink)
