Experimental studies report positive effects of signing for language acquisition and communication in children with and without language development delays. However, little data are available on natural kindergarten settings. Therefore, our study used questionnaire data to investigate the sign learning in hearing children with and without language development delays in an inclusive kindergarten group with a co-enrolled deaf child and a deaf signing educator. We observed that the hearing children in this co-enrollment group learned more signs than the hearing children (...) from groups with only hearing educators who learned signs in a training program. Hearing children’s sign learning showed a tendency toward correlating positively with their level of spoken language development. However, the individual background for children with language development delays impacted this relationship. Additionally, we examined the modality use of all children in interactions with hearing and deaf educators and peers using questionnaire and video data. Despite acquiring signs, hearing children predominantly used spoken language with hearing educators and predominantly nonverbal communication strategies with the deaf educator and the deaf child. Children with language development delays used code-blending with hearing educators in a few cases. The deaf child used mainly sign language for interactions with the deaf educator and mainly nonverbal communication with hearing educators and peers. Overall, our results suggest that the presence of a deaf educator increases sign learning in hearing children. However, in interactions during free play, they barely used signs making it particularly challenging for the deaf child to participate. This reveals that, in addition to a deaf role model, more sign language competent peers and targeted approaches increasing the use of the visual modality are required. (shrink)

A pseudo-natural algorithm for the word problem of a finitely presented group is an algorithm which not only tells us whether or not a word w equals 1 in the group but also gives a derivation of 1 from w when w equals 1. In [13], [14] Madlener and Otto show that, if we measure complexity of a primitive recursive algorithm by its level in the Grzegorczyk hierarchy, there are groups in which a pseudo-natural algorithm is arbitrarily more complicated than (...) an algorithm which simply solves the word problem. In a given group the lowest degree of complexity that can be realised by a pseudo-natural algorithm is essentially the derivational complexity of that group. Thus the result separates the derivational complexity of the word problem of a finitely presented group from its intrinsic complexity. The proof given in [13] involves the construction of a finitely presented group G from a Turing machine T such that the intrinsic complexity of the word problem for G reflects the complexity of the halting problem of T, while the derivational complexity of the word problem for G reflects the runtime complexity of T. The proof of one of the crucial lemmas in [13] is only sketched, and part of the purpose of this paper is to give the full details of this proof. We will also obtain a variant of their proof, using modular machines rather than Turing machines. As for several other results, this simplifies the proofs considerably. MSC: 03D40, 20F10. (shrink)

A diploid human genome contains approximately six billion nucleotides. This enormous amount of genetic information can be replicated with great accuracy in only a few hours. However, because DNA strands are oriented antiparallel while DNA polymerization only occurs in the 5′ → 3′ direction, semi‐conservative replication of double‐stranded DNA is an asymmetric process, i.e., there is a leading and a lagging strand. This provides a considerable opportunity for non‐random error rates, because the architecture of the two strands as well as (...) the DNA polymerases that replicate them may be different. In addition, the proteins that start or finish chains may well be different from those that perform the bulk of chain elongation. Furthermore, while replication fidelity depends on the absolute and relative concentrations of the four deoxyribonucleotide precursors, these are not equal in vivo, not constant throughout the cell cycle, and not necessarily equivalent in all cell types. Finally, the fidelity of DNA synthesis is sequence‐dependent and the eukaryotic nuclear genome is a heterogeneous substrate. It contains repetitive and non‐repetitive sequences and can actually be considered as two subgenomes that differ in nucleotide composition and gene content and that replicate at different times. The effects that each of these asymmetries may have on error rates during replication of the eukaryotic genome are discussed. (shrink)

When scientists consider the interaction of science and value judgments, debates often occur. When public policy grows out of science, disagreements between scientists can become even more spirited. This paper examines the case of nutrition policy in the United States, which has been both at the interface between agriculture and medicine and the object of serious discord concerned with the strength and validity of the scientific evidence and the responsibility for action. The development of indirect intervention policies, designed to educate (...) and inform the public on diet and health, is traced as a practical demonstration of the effects of involvements of nutritional scientists of different disciplines and philosophic bents. Controversies centered mainly on the issues of diet and coronary heart disease and of diet and cancer in nutritional guidelines for Americans and the recommended dietary allowances. But the arguments turned on a complex web of values and interests as well as scientific questions. A remarkable turnaround by animal agriculture and its scientific support occurred, changing from a defensive, rightist stance to one that appears to recognize a moral responsibility to the public health. The convincing point was likely the changing market. Nutritional scientists, however, remained divided on the issue of whether a public health strategy keyed to public education should replace a strategy to identify persons of high risk and modify the risk by treatment. Our analysis suggests that the tension between libertarian and utilitarian social values of scientists is at least as important as disagreements relative to validity and strengths of the scientific evidence.

This essay examines the growing concerns about disciplinary narrowing occurring in agricultural research and the prospects of ameliorating the detrimental effects of disciplinary compartmentalization while capitalizing on its positive effects. The general model for agricultural science is that disciplinary groupings set the logic and standards for research; the disciplinary sciences are set in a hierarchical arrangement which allows communication from the relevant basic sciences through applied research into technology development and use and problem-solving. But agricultural research throughout most of its (...) history has been goal-oriented and, therefore, is subject to ethical judgements of its worth and consequences. Also, strategic aspects of agricultural research have been subject to the evaluations and criticisms of both scientists and critics with differing interests at stake. Goals can change and organizations can be set to enable multidisciplinary and interdisciplinary research, but both goals and organizations come up against values associated with the disciplinary quality of the research, the social setting of academic science, the competition for resources, and the scientific reward system. However, there are changes underway in the agricultural scientific community which may recast the impacts of disciplinary structuring: (1) changes in the disciplinary components of subject areas and departments, (2) evolution and introductions of integrative and systems sciences into the system, (3) infusion of the same new powerful tools into most of the sciences, and (4) increased networking among scientists of different disciplines. Given that scientists' values and personalities intrude in agricultural science and research strategies, the future of agricultural research may rest on the scientists' intellectual vision and philosophical awareness that go beyond the expected disciplinary limits.

Souvent associé au genre poétique, à la fin du xix e siècle, on peut observer une application de la philosophie artistique de l’orphisme au genre romanesque. Si la finalité du poète orphique de l’époque 1900 était de créer une œuvre dans laquelle les paroles incarnent une facette du divin, tel n’est pas le souhait du romancier orphique, qui cherche plutôt à avertir un lecteur béotien de la réalité et la possibilité d’une expérience mystique — et ce afin de fournir un (...) contrepoint spirituel au climat de pessimisme engendré par la laïcisation et la décadence de la société d’alors. Dans un tel contexte, les romans de l’écrivain gallois Arthur Machen paraissent particulièrement intéressants. Reconnaissant toute forme d’expression humaine comme insuffisante pour brosser la complexité intégrale de Dieu, ainsi que toute expérience mystique, Machen n’ambitionne pas de décrire le divin, mais plutôt ses effets sur l’esprit de l’individu. Ceci se fait par une modification de la syntaxe narrative qui cherche désormais à reproduire les modulations internes que subit la pensée humaine lorsque le sujet passe entre dans un état d’extase en présence du divin. Ainsi, les romans mystiques de Machen ont pour finalité d’agir comme un catalyseur, déclenchant un éveil chez le lecteur, et le poussant à renouer avec sa propre spiritualité en-dehors du monde diégétique.

The occurrence of oscillatory behaviours in living cells can be viewed as a visible consequence of stable, regulatory homeostatic cycles. Therefore, they may be used as experimental windows on the underlying physiological mechanisms. Recent studies show that growing pollen tubes are an excellent biological model for these purposes. They unite experimental simplicity with clear oscillatory patterns of both structural and temporal features, most being measurable during real‐time in live cells. There is evidence that these cellular oscillators involve an integrated input (...) of plasma membrane ion fluxes, and a cytosolic choreography of protons, calcium and, most likely, potassium and chloride. In turn, these can create positive feedback regulation loops that are able to generate and self‐sustain a number of spatial and temporal patterns. Other features, including cell wall assembly and rheology, turgor, and the cytoskeleton, play important roles and are targets or modulators of ion dynamics. Many of these features have similarities with other cell types, notably with apical‐growing cells. Pollen tubes may thus serve as a powerful model for exploring the basis of cell growth and morphogenesis. BioEssays 23:86–94, 2001. © 2001 John Wiley & Sons, Inc. (shrink)

Artificial intelligence (AI), blockchain, virtual and augmented reality, (semi-)autonomous ve- hicles, autoregulatory weapon systems, enhancement, reproductive technologies and human- oid robotics – these technologies (and many others) are no longer speculative visions of the future; they have already found their way into our lives or are on the verge of a breakthrough. These rapid technological developments awaken a need for orientation: what distinguishes hu- man from machine and human intelligence from artificial intelligence, how far should the body be allowed to (...) be changed and what are the dangers and opportunities presented by these technologies? Many of these questions are also addressed to theology. For example, questions about the image of humanity, the understanding of creation, the ethics of technological body interventions or the moral status of robots. What does theology have to say about these technological developments? It is the right time for theology to scientifically explore tech- nologization and AI and to formulate answers. As technology changes the various areas of human life, society and the world around us, the places and topics of theology are also undergoing transformation.

Künstliche Intelligenz (KI), Blockchain, Virtual und Augmented Reality, (Teil-)Autono- mes Fahren, autoregulative Waffensysteme, Enhancement, Reproduktionstechnologien und humanoide Robotik – diese Technologien (und mit ihnen viele weitere) sind schon längst keine spekulativen Zukunftsvisionen mehr, sondern haben bereits Eingang in unser Leben gefunden oder stehen an der Schwelle zum Durchbruch. Die rasanten technologischen Ent- wicklungen wecken ein Orientierungsbedürfnis: Was unterscheidet den Menschen von der Maschine, die menschliche Intelligenz von der Künstlichen Intelligenz, wie weit sollte der Körper verändert werden dürfen, was sind die (...) Gefahren und was sind die Chancen der Tech- nologien? Viele dieser Anfragen werden auch an die Theologie gerichtet. Es wird z. B. nach dem Men- schenbild, nach dem Schöpfungsverständnis, nach einer Ethik der technologischen Körper- eingriffe oder nach dem moralischen Status von Robotern gefragt. Was sagt die Theologie zu diesen technologischen Entwicklungen? Daher ist es höchste Zeit für die Theologie, das Themenfeld der Technologisierung und KI wissenschaftlich zu ergründen und Antworten zu formulieren. Verändern sich durch die Technologisierung die verschiedenen Bereiche des menschlichen Lebens, der Gesellschaft und Mitwelt, verändern sich auch die Orte und Themen der Theologie. ---------------------------------- Puzio, Anna: Theologie und Künstliche Intelligenz – Perspektiven, Aufgaben und Thesen einer Theologie der Technologisierung.

As robots increasingly find their way into the various spheres of human life, the question of religious robots becomes relevant. This article examines from a Catholic-Christian theological perspective whether robots can be used for religious purposes, and it asks how this may be done and what issues are important to consider. In addition, the study contributes to research on the theological engagement with robotics. It is argued that the use of religious robotics dif- fers significantly depending on the specific religion. (...) From a Christian perspective, the use of religious robotics is fundamentally plausible, especially since a wide variety of entities are used as religious media or representations of the divine. However, the use of religious robotics will ultimately be decided by different concepts (e.g. human, life), religious doctrines and culturally transmitted and subjective attitudes. This article places particular focus on the design of reli- gious robotics. It becomes clear that the reasons for accepting religious technology do not lie in the technology itself but in phenomenological preferences and various time- and culture-de- pendent ideas and concepts. It is likely that as robotics rapidly advances and our relationship with it develops, the use of religious robots also will change.

Puzio, Anna: Zeig mir deine Technik und ich sag dir, wer du bist? Was Technikanthropologie ist und warum wir sie dringend brauchen. In: Diebel-Fischer, Hermann/Kunkel, Nicole/Zeyher-Quattlender, Julian (Hg.): Mensch und Maschine im Zeitalter "Künstlicher Intelligenz". Theologisch-ethische Herausforderungen. LIT 2023. -/- Abstract: Der Aufsatz untersucht das vielschichtige Verhältnis von Mensch und Technik und plädiert für eine Technikanthropologie. Wie schon Gernot Böhme für die Technikphilosophie diagnostiziert hat, gibt es die Technikanthropologie „faktisch [ . . . ] nämlich mit einschlägigen Publikationen, Curricula (...) und Lehrstühlen“ und doch scheint es „kein überzeugendes Paradigma“ der Technikanthropologie und keine Technikanthropologie als voll entwickelte Disziplin oder Denkrichtung zu geben. Der Beitrag trägt zur Profilierung der Technikanthropologie bei. Es werden Aufgaben der Technikanthropologie herausgestellt, neue Ansätze vorgestellt und wegweisende Perspektiven für eine theologische Technikanthropologie entwickelt. Im ersten Schritt wird in Abschnitt 1 in die Technikanthropologie eingeführt. Es erfolgen die Einordnung technikanthropologischer Konzepte und die Erklärung wichtiger Begriffe. Anschließend wird in Abschnitt 2 das Verhältnis von Mensch und Maschine/Technik reflektiert und verdeutlicht, wie beide im Verhältnis zueinander neu ausgehandelt werden. Es wird gegen ein vorgängiges Verständnis sowohl desMenschen als auch derMaschine/Technik plädiert und auf die jahrhundertelangen Einschreibungen in die Vorstellungen von beiden hingewiesen. Zeig mir deine Technik und ich sag dir, wer du bist? Abschnitt 3 führt aus, wie Technik Mensch und Körper verändert und mitbestimmt, wasMensch und Körper bedeuten. In diesem Kontext wird bereits die Notwendigkeit einer Neukonzeption von Technikanthropologie deutlich. Abschnitt 4 zeigt, anhand zweier Ansätze, neue Wege der Technikanthropologie auf: einen radikalen Neuentwurf des Menschen durch Donna Haraway und des Sozialen durch Bruno Latour. Schließlich werden in Abschnitt 5 Perspektiven für eine konkrete theologische Technikanthropologie entwickelt. Gerade der anthropologische Zugang zur Technik wird sich als wichtiger Zugang der Theologie zum Technikdiskurs erweisen. (shrink)
