Wittgenstein übernimmt im Tractatus das Zusammenhangsprinzip von Frege und formuliert die Doktrin von der Priorität des Satzes vor seinen Teilen, den Wörtern. Dies ist die frühste Formulierung kontextualistischen Denkens bei Wittgenstein. In der Spätphilosophie wird das "Sprachspiel" zur sinnkonstituierenden Einheit sprachlicher Kommunikation und damit zum Inbegriff kontextualistischen Denkens beim späten Wittgenstein. Eine Untersuchung der zentralen Begriffe von Wittgensteins Spätphilosophie offenbart starke Verwandtschaft zu Schapps Begriff der "Geschichten". G. Bateson führt den Terminus "Geschichte" in jenem Schappschen Sinne als Prinzip des geistigen (...) Prozesses der Informationsgewinnung bzw. Sinnkonstitution ein. Damit läßt sich über Schapps Phänomenologie der Geschichten eine Brücke von Wittgenstein zu Bateson schlagen und eine bislang unbemerkte Affinität zwischen beiden Denkern aufzeigen. Umgekehrt werden mit dem von Bateson geprägten Begriff der Transkontextualität Phänomene beschreibbar, die Wittgenstein bei der Diskussion mathematischer bzw. logischer Paradoxien behandelt. Demnach sind solche Paradoxien transkontextuelle Phänomene, die in ihrem Sinn unterbestimmt sind, ähnlich dem transkontextuellen Verhalten, das sinnbestimmende Kontexte (Sprachspiele) transzendiert und außerhalb solcher Kontexte als verrückt erscheint.

Language’s intentional nature has been highlighted as a crucial feature distinguishing it from other communication systems. Specifically, language is often thought to depend on highly structured intentional action and mutual mindreading by a communicator and recipient. Whilst similar abilities in animals can shed light on the evolution of intentionality, they remain challenging to detect unambiguously. We revisit animal intentional communication and suggest that progress in identifying analogous capacities has been complicated by (i) the assumption that intentional (that is, voluntary) production (...) of communicative acts requires mental-state attribution, and (ii) variation in approaches investigating communication across sensory modalities. To move forward, we argue that a framework fusing research across modalities and species is required. We structure intentional communication into a series of requirements, each of which can be operationalised, investigated empirically, and must be met for purposive, intentionally communicative acts to be demonstrated. Our unified approach helps elucidate the distribution of animal intentional communication and subsequently serves to clarify what is meant by attributions of intentional communication in animals and humans.

Erkennen wir die Welt so, wie sie wirklich ist oder konstruieren wir die Wirklichkeit, in der wir leben? Der einführende Artikel vom Herausgeber und der Beitrag von E. von Glasersfeld wollen zeigen, dass diese Streitfrage sich durch die ganze abendländische Philosophiegeschichte zieht. In dem Sammelband wird der Streit auf der Grundlage alter und neuer Argumente noch einmal ausgefochten. Stützen sich die einen auf die wissenschaftliche Erforschung unseres Gehirns und unserer kognitiven Fähigkeiten, um ihre These der Nichterkennbarkeit einer von uns unabhängig (...) existierenden Welt zu untermauern, so meinen die anderen, diese Argumentation sei zirkulär, ja, habe der radikale Konstruktivismus recht, so sei er widersprüchlich und damit falsch. Hinter dem konstruktivistischen Paradigma verberge sich zudem letztlich ein naiver Naturalismus, der glaubt, mit Hilfe wissenschaftlicher Forschungen allein erkenntnistheoretische Aussagen machen zu können, so die Argumentation von H.J. Wendel. Hingegen sind es vor allem Literatur- und Sozialwissenschaftler, die in etwas abgewandelter Form den Konstruktivismus durchaus als wissenschaftliches Paradigma akzeptieren. So verteidigt Wolfgang Frindte einen Sozialen Konstruktivismus, der die Auffassung vertritt, wir erzeugten unsere Wirklichkeit zusammen im Diskurs. S.J. Schmidt geht davon aus, dass soziale Systeme über Wirklichkeitsmodelle verfügen, die in der gesellschaftlichen Evolution über die Konstitution und Thematisierung für essentiell gehaltener Unterscheidungen entstehen. Verschiedene Beiträge beziehen sich explizit auf die Theorie von Humberto Maturana. Busse, Locker und Nüse erörtern in ihren Aufsätzen besonders die Problematik, die sich aus dem Konzept der Autopoiese und der daraus resultierenden Geschlossenheit des zentralen Nervensystems ergeben. O. Breidbach nimmt auf die biologische Forschung Bezug und zieht den es noch viel zu verfrüht ist, um auf dem heutigen Kenntnisstand bereits Aussagen über unsere Erkenntnisfähigkeit zu machen. Einige Beiträge befassen sich mehr mit den praktischen Auswirkungen konstruktivistischer Annahmen z.B. in der Familientherapie (Stierlin) oder in der Lerntheorie (Simon). Von Interesse sind auch die Beiträge von Hans Geisslinger, die beschreiben, wie sich unsere Wirklichkeit mit Hilfe einiger weniger Parameter verändern lässt. (shrink)

Welche ideengeschichtlichen Zusammenhänge bestehen zwischen der Philosophie Hegels und seiner Schüler einerseits und den Theorien Saint-Simons und der Saint-Simonisten andererseits? Und welches aktuelle Interesse haben diese Theorien? Diesen Fragen geht der vorliegende Band nach. In ihm wird zum einen untersucht, welche Theoriebildungen die Berührung von hegelschen und saint-simonistischen Ideen auf den Gebieten der Religions- und Geschichtsphilosophie, vor allem aber auf dem Gebiet der Sozialphilosophie begünstigt hat. Zum anderen wird die Frage erörtert, ob zentrale Elemente der hegelschen und der saint-simonistischen Theorie (...) (z.B. ihr Gesellschaftsbegriff, ihr Religionsverständnis und ihre Kritik der Politischen Ökonomie) aus heutiger Sicht anschlussfähig sind. Die vorliegende Aufsatzsammlung ist hervorgegangen aus einer internationalen, multidisziplinären Konferenz, die in Paris stattgefunden hat. (shrink)

In this paper, we consider three different search strategies for a cut-free sequent system formalizing orthologic, and estimate the respective search spaces. Applying backward search, there are classes of formulae for which both the minimal proof length and the search space are exponential. In a combined forward and backward approach, all proofs are polynomial, but the potential search space remains exponential. Using a forward strategy, the potential search space becomes polynomial yielding a polynomial decision procedure for orthologic and the word (...) problem for free ortholattices. (shrink)

ObjectiveThe use of nanotechnologies is important to reduce environmental health problems in Iran, so the present study was conducted to determine the effectiveness of nanotechnologies in environmental health. This is a cross-sectional descriptive study for 11-year periods (2008–2018) on all articles published in three specialized journals of environmental health with emphasis on the use of nanotechnologies in various fields of environmental health (water, air, sewage, waste, food, radiation, etc).ResultsIn this study, 774 articles related to 114 issues of 3 specialized environmental (...) health journals were reviewed. A review of 774 articles showed that 80 articles (10.3%) were published in the field of nanotechnologies. Out of 80 articles published in the field of nanotechnology, 66 articles (82.5%) were published on the subject of water, 9 articles (11.3%) on wastewater and 5 articles (6.2%) on air pollution. Subject review of articles showed that articles using carbon nanotubes to remove natural organic pollutants, surfactants, hydroxybenzenes, phenol, dimethyl phthalates, use of titanium dioxide nanoparticles, iron-magnesium nanoparticles for wastewater treatment, Silver nanoparticles were used to remove air pollution. The results showed that published articles on nanotechnology in the field of environmental health were few. (shrink)

What Heidegger means by “freedom” in Being and Time is somewhat mysterious: while the notion crops up repeatedly in the book, there is no dedicated section or study, and the concept is repeatedly connected to a new and opaque idea – that of the “choice to choose oneself.” Yet the specificity of Being and Time’s approach to freedom becomes apparent when the book is compared to other texts of the same period, in particular The Metaphysical Foundations of Logic, The Fundamental (...) Concepts of Metaphysics, The Essence of Grounds, and The Essence of Freedom. Although there are some differences, the definition of freedom that can be found there identifies it with “existence” or “transcendence,” Dasein’s ek-static opening onto the world. Thus “being in the world must also be primordially bound up with or derived from the basic feature of Dasein’s existence, freedom… Dasein’s transcendence and freedom are identical! Freedom provides itself with intrinsic possibility: a being is, as free, necessarily in itself transcending” (GA 26: 238; Heidegger’s italics). Note the apodictic modality of the claim: it is not simply the case that Dasein, as transcending, is free. Anything that has the structure of being in the world must be free: freedom is co-extensive with Dasein. Yet Dasein is often pictured in Being and Time as anything but free: it “ensnares itself” (268), is “lost” (264), “alienated” (178), and needs to be “liberated” (264, 303). Thus comparison between Being and Time and other texts on freedom yields an important paradox: although by definition it transcends toward the world, the Dasein of Division I is deprived of freedom. It must be free, and yet phenomenological analysis shows that it is not free. To understand the specific meaning of freedom in Being and Time, one has to square this circle. (shrink)

Validity of dynamic temporal reasoning is semantically characterized for English and Dutch aspectual adverbs in Discourse Representation Theory. This dynamic perspective determines how the content needs to be revised and what information is preserved across updates, when the order of premises is considered relevant. Resetting contextual parameters relies on modelling the basic aspectual polarity transitions and temporal reasoning extensionally. For intensional aspectual adverbials the speaker’s attitudes regarding past alternatives to and possible continuations of the current state come into play. Additional (...) considerations are offered for generalizing this system to the full logical space for linguistic universals, lexicalized quite differently in Dutch and English. (shrink)

Ns2 is an open-source communications network simulator primarily used in research and teaching. Ns2 provides substantial support for simulation of TCP, routing, and multicast protocols over wired and wireless networks. Although Ns2 is a widely used powerful simulator, it lacks a way to measure networks that are used to assess reliability and performance metrics and it does not analyse the trace files it produces. The data obtained from the simulations are not straightforward to analyse. Ns2 is still unable to provide (...) any data analysis statistics or graphics as requested. Moreover, the analysis of the Ns2 trace file using any software scripts requires further steps by a developer to do data processing and then produce graphical outputs. Lack of standardisation of tools means that results from different users may not be strictly comparable. There are alternative tools; however, most of them are not standalone applications, requiring some additional libraries. Also, they lack a user-friendly interface. This article presents the architecture and development considerations for the NsGTFA tool, which intends to simplify the management and enable the statistical analysis of trace files generated during network simulations. NsGTFA runs under Windows and has a friendly graphical user interface. This tool is a very fast standalone application implemented in VC++, taking as input an Ns2 trace file. It can output two-dimensional and 3D graphs or data sets, whatever the trace file format. It is also possible to specify the output of standard network performance metrics. NsGTFA satisfies most user needs. There is no complex installation process, and no external libraries are needed. (shrink)

In recent years, we have been observing the phenomenon of an emerging scientific field: _digital transformation research_ (DTR). Due to the diversity and complexity of its object of research digital, transformation is not effectively researchable if confined to the boundaries of individual disciplines. In the light of Scientific/Intellectual Movement theory (Frickel and Gross 2005 ), we wonder how interdisciplinarity could and should be mobilized to further advance the development of the field of DTR. To answer this question, we (a) need (...) to understand how interdisciplinarity is conceived and (b) how it is considered in research practice by researchers in the emerging field. This is important, as scientists’ application of interdisciplinarity will highly influence an emerging field, shape its growth, consolidation as well as its academic establishment. We conducted six group discussions with 26 researchers from different disciplines and career levels (PhD students, postdocs, professors). The discussions were studied with a structuring qualitative content analysis. The results reflect the vagueness of the concept of interdisciplinarity. Interdisciplinarity is largely conceived as multidisciplinarity. Further, the interviewees mentioned more challenges than opportunities when it comes to interdisciplinary DTR. The present study widens the scientific understanding about how researchers of different career levels perceive, learn, and practice interdisciplinarity in DTR. It further provides valuable indications of how interdisciplinary research in an emerging field can be profitably shaped for practice. (shrink)

While the need to protect vulnerable research participants is universal, conceptual challenges with the notion of vulnerability may result in the under or over-protection of participants. Ethics review bodies making assumptions about who is vulnerable and in what circumstance can be viewed as paternalistic if they do not consider participant viewpoints. Our study focuses on participant vulnerability in Scholarship of Teaching and Learning (SoTL) research. We aim to illuminate students’ views on participant vulnerability to contribute to critical analysis of the (...) role and processes of ethics review. Additionally, we aim to highlight the importance of seeking the views of participant communities, especially in research environments beyond ethics review’s medical origins. Thirty-four students from a health-related faculty at a university in Aotearoa New Zealand, participated in five focus groups. Participants discussed factors affecting their potential participation in research drawing upon a series of vignettes based on examples of published SoTL projects. Themes, generated using reflexive thematic analysis, built a participant-informed picture of vulnerability. Findings indicate that students do not generally consider themselves vulnerable and instead consider participation in SoTL research through an agentic lens. Students expect that participation will be voluntary, not negatively impact their grades, and not single them out so that others could judge them. Our study also highlights the value students place on relationships with one another and teaching staff and the implications these have for SoTL research participation and future professional practice. This research challenges research ethics committees to think further about vulnerability in the context of SoTL whilst highlighting the importance of providing opportunities for research participants more broadly to explore and vocalize their views as members of participant communities.

In an increasingly complex military operating environment, next generation wargaming platforms can reduce risk, decrease operating costs, and improve overall outcomes. Novel Artificial Intelligence enabled wargaming approaches, based on software platforms with multimodal interaction and visualization capacity, are essential to provide the decision-making flexibility and adaptability required to meet current and emerging realities of warfighting. We highlight three areas of development for future warfighter-machine interfaces: AI-directed decisional guidance, computationally informed decision-making, and realistic representations of decision spaces. Progress in these areas (...) will enable development of effective human-AI collaborative decision-making, to meet the increasing scale and complexity of today’s battlespace. (shrink)

The living mycelium networks are capable of efficient sensorial fusion over very large areas and distributed decision making. The information processing in the mycelium networks is implemented via propagation of electrical and chemical signals en pair with morphological changes in the mycelium structure. These information processing mechanisms are manifested in experimental laboratory findings that show that the mycelium networks exhibit rich dynamics of neuron-like spiking behaviour and a wide range of non-linear electrical properties. On an example of a single real (...) colony of _Aspergillus niger_, we demonstrate that the non-linear transformation of electrical signals and trains of extracellular voltage spikes can be used to implement logical gates and circuits. The approaches adopted include numerical modelling of excitation propagation on the mycelium network, representation of the mycelium network as a resistive and capacitive network and an experimental laboratory study on mining logical circuits in mycelium bound composites.
