In the context of our recently developed emergent quantum mechanics, and, in particular, based on an assumed sub-quantum thermodynamics, the necessity of energy quantization as originally postulated by Max Planck is explained by means of purely classical physics. Moreover, under the same premises, also the energy spectrum of the quantum mechanical harmonic oscillator is derived. Essentially, Planck’s constant h is shown to be indicative of a particle’s “zitterbewegung” and thus of a fundamental angular momentum. The latter is identified with quantum (...) mechanical spin, a residue of which is thus present even in the non-relativistic Schrödinger theory. (shrink)

In recent years, the construct of mindfulness has gained growing attention in psychological research. However, little is known about the effects of mindfulness on interpersonal interactions and social relationships at work. Addressing this gap, the purpose of this study was to investigate the role of mindfulness in leader-follower-relationships. Building on prior research, we hypothesize that leaders’ mindfulness is reflected in a specific communication style (“mindfulness in communication”), which is positively related to followers’ satisfaction with their leaders. We used nested survey (...) data from 34 leaders and 98 followers from various organizations and tested mediation hypotheses using hierarchical linear modeling. Our hypotheses were confirmed by our data. Leaders’ self-reported mindfulness showed a positive relationship with several aspects of followers’ satisfaction. This relationship was fully mediated by leaders’ mindfulness in communication as perceived by their followers. Our findings emphasize the potential value of mindfulness in workplace settings. They provide empirical evidence for a positive link between leaders’ dispositional mindfulness and the wellbeing of their followers, indicating that mindfulness is not solely an individual resource but also fosters interpersonal skills. By examining leaders’ mindfulness in communication as an explanatory process, we created additional clarification about how leaders’ mindfulness relates to followers’ perceptions. Moreover, by suggesting mindfulness in communication as a behavioral correlate of mindfulness, we offered a promising starting point for indirect measures of mindfulness. (shrink)

In this paper, we show that reproducibility is a severe problem that concerns simulation models. The reproducibility problem challenges the concept of numerical solution and hence the conception of what a simulation actually does. We provide an expanded picture of simulation that makes visible those steps of simulation modeling that are numerically relevant, but often escape notice in accounts of simulation. Examining these steps and analyzing a number of pertinent examples, we argue that numerical solutions are importantly different from usual (...) mathematical solutions. They are do not merely approximate the latter, but introduce new problems, including issues of artificiality, stability, and well-posedness. Consequently, simulation modelling can attain reproducibility only to a certain degree because it is working with numerical solutions. (shrink)

The ongoing debate on the ethics of self-driving cars typically focuses on two approaches to answering such questions: moral philosophy and social science. I argue that these two approaches are both lacking. We should neither deduce answers from individual moral theories nor should we expect social science to give us complete answers. To supplement these approaches, we should turn to political philosophy. The issues we face are collective decisions that we make together rather than individual decisions we make in light (...) of what we each have reason to value. Political philosophy adds three basic concerns to our conceptual toolkit: reasonable pluralism, human agency, and legitimacy. These three concerns have so far been largely overlooked in the debate on the ethics of self-driving cars. (shrink)

The paper develops a precise account of a logic of truth and, in particular, the logic of truth of a given truth theory. On the basis of this account maximality considerations are employed for comparing and evaluating different classical logics of truth. It is argued that, perhaps surprisingly, maximality considerations lead to a fruitful criterion for evaluating logics of truth. The paper provides two different routes for motivating the application of maximality considerations in the truth case. The first route employs (...) the Maxim of Minimum Mutilation and suggests that we should vindicate as much of our basic truth intuition, that is, the transparency intuition, as it is consistently possible. The second route argues that maximality considerations underlie much of our logical theorizing and its application in the truth case is just one particular such instance. On this view maximality considerations do not implicitly depend on the basic truth intuition but rather explain how the intuition arises and why it is not fully reliable. (shrink)

Despite growing evidence to the contrary, researchers continue to posit causal links between cannabis, crime, psychosis, and violence. These spurious connections are rooted in history and fueled decades of structural limitations that shaped how researchers studied cannabis. Until recently, research in this area was explicitly funded to link cannabis use and harm and ignore any potential benefits. Post-prohibition cannabis research has failed to replicate the dire findings of the past. This article outlines how the history of controlling cannabis research has (...) led to various harms, injustices, and ethical complications. We compare commonly cited research from both the prohibition and post-prohibition eras and argue that many popular claims about the dangers of cannabis are the result of ethical lapses by researchers, journals, and funders. We propose researchers in this area adopt a duty of care in cannabis research going forward. This would oblige individual researchers to establish robust research designs, employ careful analytic strategies, and acknowledge limitations in more detail. This duty involves the institutional recognition by funders, journals, and others that cannabis research has been deliberately misconstrued to criminalize, stigmatize, and pathologize. (shrink)

The idea of a firm connection of the seven artes liberales came first into being in Augustine's early concept of education. Whereas this idea has been analyzed primarily in view of its philosophical sources, this paper is supposed to clarify its internal logic. The main feature of Augustine's concept is the distinction between the two projects of a critique of reason and of a metaphysics, and the coordination of these projects within a treatise on theodicy. Augustine systematizes the disciplinae in (...) the perspective of reason's self-recognition. Reason manifests itself in culture and nature. Through the sciences, reason is led to a reflection upon its own products and, finally, to an understanding of them as reason's self-manifestations. Thus, reason becomes able to comprehend itself. Augustine distinguishes language-based disciplinae from number-oriented ones. The first group leads to a critical reflection upon the conditions of knowledge and into the insight to reason's power of creating sciences. The second group helps carry out a metaphysical ascent from the material to the intelligible world. In philosophy, reason comprehends its ability to constitute knowledge as a synthetic capacity that points to a transnumerical unity as the main ontological feature of the intelligible world. The insight into this kind of unity reveals the meaningful interwovenness of all beings and events and, thus, leads to a refutation of all objections against divine providence. (shrink)

The scientific and practical fields—especially high-performance sports—increasingly request a stronger focus be placed on individual athletes in human movement science research. Machine learning methods have shown efficacy in this context by identifying the unique movement patterns of individuals and distinguishing their intra-individual changes over time. The objective of this investigation is to analyze biomechanically described movement patterns during the fatigue-related accumulation process within a single training session of a high number of repeated executions of a ballistic sports movement—specifically, the frontal (...) foot kick (mae-geri) in karate—in expert athletes. The two leading research questions presented for consideration are (1) Can characteristics of individual movement patterns be observed throughout the entire training session despite continuous changes, i.e., even as fatigue-related processes increase? and (2) How do intra-individual movement patterns change as fatigue-related processes increase throughout a training session? Sixteen expert karatekas performed 606 frontal foot kicks directed toward an imaginary target. The kicks were performed in nine sets at 80% (K-80) of the self-experienced maximal intensity. In addition, six kicks at maximal intensity (K-100) were performed after each of the nine sets. Between the sets, the participants took a 90-s break. Three-dimensional full-body kinematic data of all kicks were recorded with 10 infrared cameras. The normalized waveforms of nine upper- and lower-body joint angles were classified using a supervised machine learning method (support vector machine). The results of the classification revealed a disjunct distinction between the kinematic movement patterns of individual athletes. The identification of unique movement patterns of individual athletes was independent of the intensity and the degree of fatigue-related processes. In other words, even with the accumulation of fatigue-related processes, the unique movement patterns of an individual athlete can be clearly identified. During the training session, changes in intra-individual movement patterns could also be detected, indicating the occurrence of adaptations in individual movement patterns throughout the fatigue-related accumulation process. The results suggest that these adaptations can be modeled in terms of changes in patterns rather than increasing variance. Practical consequences are critically discussed. (shrink)

Modularity is a key concept in building and evaluating complex simulation models. My main claim is that in simulation modeling modularity degenerates for systematic methodological reasons. Consequently, it is hard, if not impossible, to accessing how representational structure and dynamical properties of a model are related. The resulting problem for validating models is one of holism. The argument will proceed by analyzing the techniques of parameterization, tuning, and kludging. They are – to a certain extent – inevitable when building complex (...) simulation models, but corrode modularity. As a result, the common account of validating simulations faces a major problem and testing the dynamical behavior of simulation models becomes all the more important. Finally, I will ask in what circumstances this might be sufficient for model validation. (shrink)

Normativität hat in den Sozialwissenschaften noch immer etwas Anrüchiges, fast Abschreckendes. Es gibt eine lange Traditionslinie in den Sozialwissenschaften, die versucht, ihre Disziplin gegenüber normativen Argumenten „sauber“ zu halten. Das wird in der Regel damit begründet, dass im wissenschaftlichen Erkenntnisprozess Gesinnungsmotive nicht hilfreich sind und im Extremfall Ergebnisse verzerren. Befürworter normativer Sozialwissenschaften halten dagegen, dass die fehlende Thematisierung etwa von sozialen Ungleichheits- und Herrschaftsverhältnissen die Welt, so wie sie gerade ist, einmal mehr bestätigt – und das ist eben auch nicht (...) normfrei und kann es auch nicht sein, weil, so eine zentrale These des vorliegenden Bandes, Theorien notwendig mit normativen Bezügen behaftet sind. Damit ist das Spektrum der Positionen angedeutet, die in diesem Sammelband zu finden sind. Er hat einerseits das Ziel, normative Verwicklungen auch in den sozialwissenschaftlichen Ansätzen aufzuspüren, die stärker auf die Idee einer wertfreien Wissenschaft verpflichtet sind. Andererseits werden Ansätze, die explizit herrschaftskritische Positionen vertreten, auf die Plausibilität ihrer normativen Setzungen hin überprüft. Die normativen Hintergründe sozialwissenschaftlicher Theoriebildung aufzuzeigen und eine Debatte über die normativen Bezüge der Sozialwissenschaften anzuregen ist das Anliegen dieses Bandes.

Thought experiments and simulation experiments are compared and contrasted with each other. While the former rely on epistemic transparency as a working condition, in the latter complexity of model dynamics leads to epistemic opacity. The difference is elucidated by a discussion of the different kinds of iteration that are at work in both sorts of experiment.

In this editorial introduction, we set out the contexts, aims and contents of this special issue on Schelling’s influence on later religious and theological thought, as well as the rationale behind its genesis.

Zusammenfassung Habermas fragt vor dem Hintergrund geschwächter Kräfte der sozialen Integration in kritischem Bezug auf Carl Schmitt nach dem vernünftigen Sinn der alteuropäischen Kategorie des Politischen. Schmitt versteht seinen Begriff des Politischen im Sinne des jus reformandi, mit dem sich die Reformatoren für das Politische in seiner klassischen Gestalt und für religiösen Zwang entscheiden. Habermas erhofft sich einen komplementären Lernprozess von religiösen und säkularen Bürgern und vom eschatologischen Denken einer unter demokratischen Bedingungen erneuerten Politischen Theologie, dass es gegenüber einem idealisierenden, (...) normativen Denken ‚Zeitempfindlichkeit‘ einklagt. Sein Ansatz bei der in Geschichte und Sprache inkarnierten Vernunft ist einer am Ereignis des Wortes Gottes und der Kommunikation des Evangeliums orientierten Theologie eng verbunden und hilft deren Bedeutung für das Politische zu klären.

Digitalisierung wird im vorliegenden Band aus der Theorieperspektive der Philosophischen Anthropologie Plessners betrachtet. Damit geht es im Kern darum, ob und inwieweit sich das Verhältnis von Mensch und Welt im Zeichen von Digitalisierung verändert. Die Verwendung unterschiedlicher Theoriefiguren, Thesen und Themenstellungen aus Plessners Werk erlaubt, die Vielfalt dessen, was mit Digitalisierung verbunden wird, zu systematisieren. Indem mit Plessner der Mensch verstanden wird als exzentrisch positionales Selbst, das Kognitives und Materiales verbindet, steht im Mittelpunkt, wie sich der Mensch eine Welt schafft, (...) die ihn selbst potentiell überformt. Gesellschaft, Autonomie, Technik, Stufen (im plessnerschen Sinne) und schliesslich der Mensch selbst sind die fünf Aspekte, die in den verschiedenen Beiträgen entfaltet werden: Was sind Charakteristika einer digitalen Gesellschaft? Geht die Epoche individueller Freiheit zu Ende? Was bedeutet Digitalisierung für die Autonomie des Menschen? In welches Verhältnis treten Mensch und Technik? Bringt Digitalisierung eine neue Stufe superior des Menschen hervor? Und wo bleibt der Mensch in der Digitalisierung?0. (shrink)
