We investigate the application of Courcelle’s theorem and the logspace version of Elberfeld et al. in the context of non-monotonic reasoning. Here we formalize the implication problem for propositional sets of formulas, the extension existence problem for default logic, the expansion existence problem for autoepistemic logic, the circumscriptive inference problem, as well as the abduction problem in monadic second order logic and thereby obtain fixed-parameter time and space efficient algorithms for these problems. On the other hand, we exhibit, for each (...) of the above problems, families of instances of a very simple structure that, for a wide range of different parameterizations, do not have efficient fixed-parameter algorithms (even in the sense of the large class XPnu, resp., XLnu) under standard complexity assumptions.

Die Studie betritt und erschliesst sowohl in ihrem Gegenstandsbereich als auch in methodologischer Hinsicht literaturwissenschaftliches Neuland. Vor dem Hintergrund der Auseinandersetzung deutschsprachiger Schriftsteller mit den für sie unlesbaren chinesischen Schriftzeichen entwickelt sie den Begriff der 'ästhetischen Resonanz' und erforscht die Präsenz und Funktion chinesischer Schriftzeichen in der deutschen Literatur- und Wissenschaftsgeschichte vom 17. bis zum 20. Jahrhundert. Sie fragt, welche Inspirationen die deutschsprachige Literatur aus der Begegnung mit diesen Schriftzeichen und poetischen Formen erhalten hat, was dann exemplarisch an Werken von (...) Ludwig August Unzer, Johann Wolfgang von Goethe, Friedrich Rückert, Yvan Goll, Albert Ehrenstein, Max Dauthendey und Max Kommerell aufgezeigt wird. Mit dem methodisch-theoretischen Ansatz der ästhetischen Resonanz wird der literaturwissenschaftlichen Forschung ein ganz neues Untersuchungsfeld eröffnet und definiert, in dem sprachliche Zeichen nicht mehr primär nach ihrem Sinngehalt oder ihrer signifikanten Struktur befragt werden, sondern nach ihrer affektiven und ästhetischen Wirkung. Für deren Analyse wird mit dem Konzept einer post-semiotischen Resonanzästhetik ein Ausgangspunkt geschaffen und zur Diskussion gestellt, von dem aus das vermeintlich Unlesbare diskursiv lesbar wird."--Publisher's description from Deutsche Nationalbibliothek.

Dass man eine musikalische Form auberschaubaro - und nicht etwa auberhorbaro - nennt, mutet ebenso selbstverstandlich an wie der immer wieder formulierte Vergleich zwischen Musik und Architektur.

In diesem Beitrag kommentieren die Autor:innen zunächst den von Drerup entwickelten Orientierungsrahmen und folgen den basalen Schlüssen des Autoren, zeigen aber auch Leerstellen und eigene Schwerpunktsetzungen auf. Der kritische Teil des Beitrags konzentriert sich auf die Kommentierung der Leitlinien für die Unterrichtspraxis für Lehrkräfte, die von Johannes Drerup zur als Hilfestellung für Lehrkräfte als Basis für einen am Kontroversitätsgebot orientierten Unterricht entwickelt wurden. Das diesen Leitlinien inhärente Vorhaben Drerups, den zweiten Grundsatz des Beutelsbacher Konsens’ zu konkretisieren, wird aus Sicht (...) der Autor:innen diskutiert. Sie zeigen auf, welche Grenzen gültiger Meinungen in der Rezeption des Beutelsbacher Konsens’ bereits formuliert wurden, um „radikal offene Kontroversitätspostulate” zu vermeiden. Die Autor:innen argumentieren außerdem gegen das von Drerup angelegte Bildungsverständnis der Demokratieerziehung und dem darin angelegten Rollenkonzept von Lehrer:innen als wissen(schaft)svermittelnde Akteure, die im Zentrum des Unterrichts stehen. Diese zugrundeliegende Prämisse hat aus Sicht der Autor:innen ungünstige Konsequenzen und führt zu einer verengten Perspektive auf die Lehrkraft. Die Autor:innen plädieren vielmehr für eine subjektorientierte Bildung, die die Lernenden und ihre mitgebrachten Konzepte und Vorstellungen in den Mittelpunkt stellt und nicht die Rolle der Lehrkraft. So kann der Blick geweitet werden für die Potenziale, die die Demokratiebildung bereit hält. (shrink)

English Summary The main focus of this article is a church, the picture of which is shown on a gravure by Gugas İnciciyan and called Arslanhane (Menagerie)/Nakkaşhane (House of painters). The church has a central dome, an apsis and a semi dome at the west side and looks like a little model of the Hagia Sophia. It was erected above an other building with a central arch. This resembles descriptions of the Chalke gate and the Chalke church in several written (...) sources. Some chraracteristic marks of İnciciyan's church can also be discovered on some other drawings from various artists (Matrakçi Nasuh 1537; Melchior Lorichs, 1559; Cornelius Loos, 1710). A comparison with them helps us to localise it on the southern side of the former university building of Gaspare Fossati. Written sources inform us that the so called Arslanhane/Nakkaşhane of Inciciyan was not the only the building, which was converted to a menagerie. The church of Johannes in the Diippion and an other building, near the southwest corner of the Hagia Sophia were also used as menagerie during the Ottoman period. Especially the second one can be seen on various drawings. In our opinion Mango's identification of a church drawn by Willey Reveley (1786) with the Chalke, must be reviewed, since it was probably that of Theotokos Varaniotissa, which was renewed in the late Byzantine era.

This paper has the aim of making Johannes von Kries’s masterpiece, Die Principien der Wahrscheinlichkeitsrechnung of 1886, a little more accessible to the modern reader in three modest ways: first, it discusses the historical background to the book ; next, it summarizes the basic elements of von Kries’s approach ; and finally, it examines the so-called “principle of cogent reason” with which von Kries’s name is often identified in the English literature.

Anhand einer klinischen Vignette wird ausgeführt, dass das psychoanalytische Geschehen sich in mehreren Dimensionen entfaltet. Drei solcher Dimensionen – als Bedeutung (Erkenntnis), Berührung (Kontakt) und Bewegung (Ereignis) bezeichnet – werden beschrieben und deren dimensionale Charakteristik auf die Sinnesqualitäten des Sehens, des Berührungssinnes und des Hörens bezogen. Es wird gezeigt, dass sie Raum und Zeit auf je eigene Weise konstituieren und somit einander inkommensurable, durch keine logische oder dialektische Operation in eine Einheit überführbare Aprioritäten darstellen. Mit deren Unvereinbarkeit ist auch auf (...) Grenzen theoretisch-begrifflicher Bemächtigung verwiesen, womit die Frage nach der Reichweite metapsychologischer Begriffe, etwa des Begriffs des Unbewussten, aufgeworfen ist. Von hier aus wird in einem Ausblick nach der Begegnung als organisierendem Phantasma der analytischen Situation gefragt und – auf dem Weg einer Erörterung des Begegnungsbegriffs bei Martin Buber – versucht, Begegnung dimensional näher zu bestimmen.

Much of the debate on the ethics of self-driving cars has revolved around trolley scenarios. This paper instead takes up the political or institutional question of who should decide how a self-driving car drives. Specifically, this paper is on the question of whether and why passengers should be able to control how their car drives. The paper reviews existing arguments—those for passenger ethics settings and for mandatory ethics settings respectively—and argues that they fail. Although the arguments are not successful, they (...) serve as the basis to formulate desiderata that any approach to regulating the driving behavior of self-driving cars ought to fulfill. The paper then proposes one way of designing passenger ethics settings that meets these desiderata. (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)

Investment protection clauses, and the investor-state dispute settlement mechanisms they enable, have become a common feature of international agreements on trade and investment. Intended to promote foreign investment, these protections may also discourage governments from regulating in the public interest. This raises challenging normative questions about the rights of investors and distributive justice. In this paper, I argue that a global investment regime that disadvantages developing countries and socially disadvantaged groups is prima facie unfair. This conclusion must be defended against (...) the claim that investors have certain independent moral rights to have their property protected, regardless of the distributive consequences. Granting the premise that such investor rights exist, I argue that these cannot plausibly ground a general rule against public interest regulation that undermines the value of property. I conclude that even if foreign investors have rights that must be safeguarded, the current investment regime must be reformed. (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)

This article uses sociological role theory to help understand ethical challenges faced by Norwegian real estate agents. The article begins with an introductory case, and then briefly examines the strengths and limitations of using legal definitions and rules for understanding real estate agency and real estate agent ethics. It goes on to argue that the ethical challenges of real estate agency can be described and understood as a system of conflicting roles with associated rights and duties, in particular sales agent, (...) intermediary and adviser sub-roles. The arguments are developed using exploratory findings from a survey of Norwegian real estate agents and from several focus groups. The article then suggests the use of various intranet tools as a kind of action research aimed at putting ethics on the real estate agents' agenda, working to develop a collective conscience and collective selfcriticism among the agents, and, in doing so, building bridges between academic research and the practical working world of the agents.

WHAT IS PRESENT TO THE MIND? Donald DAVIDSON The University of California at Berkeley There is a sense in which anything we think about is, ...

Brain-computer interfaces are envisioned to enable new abilities of action. This potential can be fruitful in particular when it comes to restoring lost motion or communication abilities or to implementing new possibilities of action. However, BCIs do not come without presuppositions. Applying the concept of ability expectations to BCIs, a wide range of requirements on the side of the users becomes apparent. We examined these ability expectations by taking the example of therapeutic BCI users who got enrolled into BCI research (...) studies due to particular physical conditions. Some of the expectations identified are quite explicit, like particular physical conditions and BCI “literacy”. Other expectations are more implicit, such as motivation, a high level of concentration, pain tolerance, emotion control and resources. These expectations may produce a conception of the human and a self-understanding among BCI users that objectify the body in favour of a brain-centred, cerebral notion of the subject which also plays its part in upholding a normality regime.

I would like to look at some of the challenges of ethcis today. Therefore, in the first part I say something about ethics, the ethical theories and ethical concepts. Afterwords I am going to explain a little bit about the human dimensions, the dealing with experiences (i.e. work); because the human person has to decide the right thing in the right place on the right time, and in relatively freedom. In the end, there are some ideas about applied ethics which (...) is necessary to focusing on the practical issues, too. Otherwise people who do not like the ethical discussions they could think that ethical ideas are selfsufficient and do not make sense, but I will tell them something else... (shrink)

In the strategic document of the African Union approved in 2013 and spanning over 50 years, known as Agenda 2063, we find a blueprint for transforming Africa into a global powerhouse of the future. Many of the themes mentioned in Agenda 2063 are also mentioned in the New Testament, such as slavery, unity, poverty, women, children, discrimination and diversity. It is therefore clear that Christianity has something to contribute to Agenda 2063. Another word used throughout the Agenda 2063 document is (...) ‘transformation’. Concepts such as ‘transformative leadership’ and ‘radical transformation at all levels and in all spheres’ are mentioned. This contribution draws on the Agenda 2063 document to engage the missiological themes of unity, reconciliation and justice through the lens of the Belhar Confession. Deeply aware of the pain and disruption colonial Christianity has caused in many instances in Africa, the author contends that the Good News, particularly the New Testament themes of unity, reconciliation and justice, present a potentially transformative approach towards developing Africa. The research question that this article attends to is: how can the churches in Africa contribute to the aspirations of Agenda 2063 from the themes of unity, justice and reconciliation as declared in the Belhar Confession? By interrogating these key concepts of Agenda 2063 through the Confession of Belhar, the author concludes that the Belhar Confession can be regarded as a key African document, which could be explored further to facilitate unity, reconciliation and justice on the continent.Contribution: This article indicates the important relationship between church and state and the need for a partnership for the benefit of both. The need for a transforming state and a transforming church to participate in a transformed Africa is argued. The article promotes multi-, inter- and transdisciplinary aspects of studies as part of a mission praxis and application. (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)

Polygenic effects have more than one cause. They testify to the fact that several causal contributors are sometimes simultaneously involved in causation. The importance of polygenic causation was noticed early on by Mill (1893). It has since been shown to be a problem for causal-law approaches to causation and accounts of causation cast in terms of capacities. However, polygenic causation needs to be examined more thoroughly in the emerging literature on causal mechanisms. In this paper I examine whether an influential (...) theory of mechanisms proposed by Peter Machamer, Lindley Darden and Carl Craver can accommodate polygenic effects and other forms of causal interaction. This theory is problematic, I will argue, because it ascribes a central role to activities. In it, activities are needed not only to constitute mechanisms but also to perform the causal role of mechanisms. Any such mechanism-as-activity will be incompatible with causal situations where either no or merely another kind of activity occurs. But, as I will try to illustrate in this paper, both kinds of situation may be frequent. If I am right, the view that Machamer and colleagues suggest leads to an impoverished conception of mechanism.

Researchers often aim to make correct inferences both about that which is actually studied and about what the results generalize to. The language of internal and external validity is not used by everyone, but many of us would agree that intuitively the distinction makes a lot of sense. Two claims are commonly made with respect to internal and external validity. The first is that internal validity is prior to external validity since there is nothing to generalize if the findings obtained (...) in, for instance, the experimental setting do not hold. The first claim is explicit in many writings. See for instance Francisco Guala’s influential book The methodology of experimental economics. And it is often implicitly relied on. The second claim is that researchers have to make a trade-off between internal and external validity. When one is increased, the other will decrease. The second claim was made already from the start by D.T Campbell in his classic Factors relevant to the validity of experiments in social settings. There is a certain tension between the first and the second claim. It has been argued before that it might be difficult to combine them. We intend to make the stronger point that both claims are misconstrued. Our hypothesis is that the relationship between internal and external validity has to be re-conceptualized, and we will briefly indicate how. (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.

In diesem Gesamtkurs seiner Philosophie bringt Johannes Heinrichs die Essenz seiner bisherigen Bücher auf den Punkt - eine konsequente, reichhaltige und neuartige Systematik aus einem Guss, die vielen derzeitigen Moden trotzt. Im erkenntnistheoretischen Einführungskapitel wird Reflexion (Selbstbezüglichkeit) als die Denkform thematisiert, die sich selbst als gelebte Reflexion zum Inhalt hat. Ein anthropologisches Kapitel führt die von der abendländischen Philosophie ignorierte und der Esoterik überlassene Körper-Seele-Geist-Einheit methodisch aus. Im dritten Kapitel wird die Reflexion als soziales System thematisiert: eine Kurzfassung der (...) bekannten Sozial-und Demokratietheorie des Autors. Es folgen die Kapitel zu Handlung - Sprache - Kunst und Mystik. Nach der Grundhypothese der von Heinrichs begründeten philosophischen Semiotik (Sinnprozesslehre) bauen sie reflexionsgestuft aufeinander auf. Während etwa das Sprachkapitel sein ganzes fünfbändiges Werk authentisch zusammenfasst, bietet das Mystikkapitel erstmals eine kurzgefasste Religionsphilosophie, der ein Umriss strukturaler und integraler Ontologie folgt. Vollends beweist ein Überblick über die ethischen Positionen die Fruchtbarkeit der reflexionstheoretischen Methodik. (shrink)
