Precision medicine and molecular systems medicine (MSM) are highly utilized and successful approaches to improve understanding, diagnosis, and treatment of many diseases from bench-to-bedside. Especially in the COVID-19 pandemic, molecular techniques and biotechnological innovation have proven to be of utmost importance for rapid developments in disease diagnostics and treatment, including DNA and RNA sequencing technology, treatment with drugs and natural products and vaccine development. The COVID-19 crisis, however, has also demonstrated the need for systemic thinking and transdisciplinarity and the limits (...) of MSM: the neglect of the bio-psycho-social systemic nature of humans and their context as the object of individual therapeutic and population-oriented interventions. COVID-19 illustrates how a medical problem requires a transdisciplinary approach in epidemiology, pathology, internal medicine, public health, environmental medicine, and socio-economic modeling. Regarding the need for conceptual integration of these different kinds of knowledge we suggest the application of general system theory (GST). This approach endorses an organism-centered view on health and disease, which according to Ludwig von Bertalanffy who was the founder of GST, we call Organismal Systems Medicine (OSM). We argue that systems science offers wider applications in the field of pathology and can contribute to an integrative systems medicine by (i) integration of evidence across functional and structural differentially scaled subsystems, (ii) conceptualization of complex multilevel systems, and (iii) suggesting mechanisms and non-linear relationships underlying the observed phenomena. We underline these points with a proposal on multi-level systems pathology including neurophysiology, endocrinology, immune system, genetics, and general metabolism. An integration of these areas is necessary to understand excess mortality rates and polypharmacological treatments. In the pandemic era this multi-level systems pathology is most important to assess potential vaccines, their effectiveness, short-, and long-time adverse effects. We further argue that these conceptual frameworks are not only valid in the COVID-19 era but also important to be integrated in a medicinal curriculum. (shrink)

We consider the problem of quadrilaterizing an orthogonal polygon P, that is to decompose P into nonoverlapping convex quadrangles without adding new vertices. In this paper we present a CREW-algorithm for this problem which runs in O time using Θ processors if the rectangle decomposition of P is given, and Θ processors if not. Furthermore we will show that the latter result is optimal if the polygon is allowed to contain holes.

„On 23rd February 2022, when the editors had worked out topical issues of dispute relating to politics, ethics, technology and religion for a Hans Jonas Centre conference on responsibility for the future and discourse ethics, it was suddenly foreseeable that Russia would invade the core area of Ukraine the next night. We immediately informed our Ukrainian colleagues that we would allow them asylum, if desired, and invite them to the conference in Bad Kissingen as keynote speakers. In no time at (...) all, the new programme for the confer-ence was ready: After commemorating Hans Jonas' honorary doctorate in Berlin under the motto ‘Fatalism would be a mortal sin’ exactly 30 years ago, we now focus on ‘Discourse despite war’. After that, we discuss digitalisation as well as theology, philosophy and commitment".

Called by Karl Barth the brilliant Ethics of Dietrich Bonhoeffer, this book is finally being recognized as Bonhoeffers magnum opus and one of the most important works of Christian ethics of the last century.

We investigated the impact of frequency of interruptions in a simulated medical visual search task. Participants performed the visual search task during which they were interrupted by a number-classification task in 25, 50, or 75% of all trials, respectively, reflecting the frequency conditions. Target presence and interruption were varied within-subjects, and interruption frequency was varied between-subjects. Globally, on a frequency condition level, participants in the low frequency condition had longer mean response times for the primary visual search task than in (...) the high condition, but there were no other performance differences between the three frequency conditions. Locally, on the level of specific interruption effects, accuracy decreased directly after interruptions for target present but not for target absent trials. Furthermore, interruptions caused significant interruption costs, reflected in slower overall RTs in interrupted than in uninterrupted trials. The combined findings show that especially for critical visual search tasks as in the medical field, interruptions—regardless of frequency—should be avoided. (shrink)

Summary A large survey of German and Israeli younger and older adolescents was conducted to reveal their opinions and attitudes towards violence and aggression, their personal engagement in aggressive and violent behaviors in and outside the school environment, their attitudes toward physical activity, their engagement in physical activity, and the linkage between physical activity engagement and conductance of violence and aggression. The findings point out that there are more similarities than differences between German and Israeli adolescents concerning violence and aggression (...) in and outside schools. No linkage between physical activity involvement and the extent of violent and/or aggressive acts is found. The findings pertaining adolescents’ opinions and attitudes toward aggression and violence and their behaviors in and outside school are encouraging. (shrink)

In solving judgment aggregation problems, groups often face constraints. Many decision problems can be modelled in terms the acceptance or rejection of certain propositions in a language, and constraints as propositions that the decisions should be consistent with. For example, court judgments in breach-of-contract cases should be consistent with the constraint that action and obligation are necessary and sufficient for liability; judgments on how to rank several options in an order of preference with the constraint of transitivity; and judgments on (...) budget items with budgetary constraints. Often more or less demanding constraints on decisions are imaginable. For instance, in preference ranking problems, the transitivity constraint is often contrasted with the weaker acyclicity constraint. In this paper, we make constraints explicit in judgment aggregation by relativizing the rationality conditions of consistency and deductive closure to a constraint set, whose variation yields more or less strong notions of rationality. We review several general results on judgment aggregation in light of such constraints. (shrink)

The Christian does not live in a vacuum, says the author, but in a world of government, politics, labor, and marriage. Hence, Christian ethics cannot exist in a vacuum what the Christian needs, claims Dietrich Bonhoeffer, is concrete instruction in a concrete situation. Although the author died before completing his work, this book is recognized as a major contribution to Christian ethics. The root and ground of Christian ethics, the author says, is the reality of God as revealed in (...) Jesus Christ. This reality is not manifest in the Church as distinct from the secular world such a juxtaposition of two separate spheres, Bonhoeffer insists, is a denial of God's having reconciled the whole world to himself in Christ. On the contrary, God's commandment is to be found and known in the Church, the family, labor, and government. His commandment permits man to live as man before God, in a world God made, with responsibility for the institutions of that world. (shrink)

Agents are often assumed to have degrees of belief (“credences”) and also binary beliefs (“beliefs simpliciter”). How are these related to each other? A much-discussed answer asserts that it is rational to believe a proposition if and only if one has a high enough degree of belief in it. But this answer runs into the “lottery paradox”: the set of believed propositions may violate the key rationality conditions of consistency and deductive closure. In earlier work, we showed that this problem (...) generalizes: there exists no local function from degrees of belief to binary beliefs that satisfies some minimal conditions of rationality and non-triviality. “Locality” means that the binary belief in each proposition depends only on the degree of belief in that proposition, not on the degrees of belief in others. One might think that the impossibility can be avoided by dropping the assumption that binary beliefs are a function of degrees of belief. We prove that, even if we drop the “functionality” restriction, there still exists no local relation between degrees of belief and binary beliefs that satisfies some minimal conditions. Thus functionality is not the source of the impossibility; its source is the condition of locality. If there is any non-trivial relation between degrees of belief and binary beliefs at all, it must be a “holistic” one. We explore several concrete forms this “holistic” relation could take. (shrink)

In the theory of judgment aggregation, it is known for which agendas of propositions it is possible to aggregate individual judgments into collective ones in accordance with the Arrow-inspired requirements of universal domain, collective rationality, unanimity preservation, non-dictatorship and propositionwise independence. But it is only partially known (e.g., only in the monotonic case) for which agendas it is possible to respect additional requirements, notably non-oligarchy, anonymity, no individual veto power, or implication preservation. We fully characterize the agendas for which there (...) are such possibilities, thereby answering the most salient open questions about propositionwise judgment aggregation. Our results build on earlier results by Nehring and Puppe (2002), Nehring (2006), Dietrich and List (2007a) and Dokow and Holzman (2010a). (shrink)

Plants are interpreted as structural hierarchies which are real systems organized through descending constraints. Types of hierarchical groups in plants are (a) cluster by integration, (b) support through attachment, (c) enclosure by encasement (d) dissipative by input of energy and (e) control through variable state switching. Most plant hierarchies are mixtures of these types which explains a number of paradoxes in plant morphology. The traditional means of identifying levels, i.e., cell, tissues, organs, uses a compositional group which is not a (...) hierarchical group but a similarity feature and so is inadequate for describing hierarchies. Hierarchies can be defined by set theory which is more a description of cognitive than real hierarchies and therefore is of little value in describing plant organization. The hierarchical description of a plant emphasizes the immediate physical status of organization which provide, in turn, a physical explanation of development. (shrink)

There is a prevalent notion among cognitive scientists and philosophers of mind that computers are merely formal symbol manipulators, performing the actions they do solely on the basis of the syntactic properties of the symbols they manipulate. This view of computers has allowed some philosophers to divorce semantics from computational explanations. Semantic content, then, becomes something one adds to computational explanations to get psychological explanations. Other philosophers, such as Stephen Stich, have taken a stronger view, advocating doing away with semantics (...) entirely. This paper argues that a correct account of computation requires us to attribute content to computational processes in order to explain which functions are being computed. This entails that computational psychology must countenance mental representations. Since anti-semantic positions are incompatible with computational psychology thus construed, they ought to be rejected. Lastly, I argue that in an important sense, computers are not formal symbol manipulators. (shrink)

In der europäischen Kunstgeschichte ist seit den Arbeiten Alois Riegls vor gut einhundert Jahren nach und nach die Auffassung Gemeingut geworden, dass die Antike über die römische Kaiserzeit hinweg fortdauerte und dass spätantiker Kunst eine eigene Wertigkeit zuzusprechen ist – von Rom als dem „Ende der Antike“ kann nur insoweit die Rede sein, als die Christianisierung des Römischen Reiches auch die Kunst einem starken Wandel unterwarf. Nicht einmal die arabische Eroberung weiter Teile des Oströmischen Reiches im 7. Jahrhundert bedeutete für (...) diese Gebiete einen Bruch mit der Kultur der Spätantike. Die Absicht, diese These durch kunsthistorische Beobachtungen zu erhärten, formuliert Garth Fowden (F.) schon mit dem Untertitel seines Buches über Qusayr ‘Amra. (shrink)

The widely discussed "discursive dilemma" shows that majority voting in a group of individuals on logically connected propositions may produce irrational collective judgments. We generalize majority voting by considering quota rules, which accept each proposition if and only if the number of individuals accepting it exceeds a given threshold, where different thresholds may be used for different propositions. After characterizing quota rules, we prove necessary and sufficient conditions on the required thresholds for various collective rationality requirements. We also consider sequential (...) quota rules, which ensure collective rationality by adjudicating propositions sequentially and letting earlier judgments constrain later ones. Sequential rules may be path-dependent and strategically manipulable. We characterize path-independence and prove its essential equivalence to strategy-proofness. Our results shed light on the rationality of simple-, super-, and sub-majoritarian decision-making. (shrink)

Behaviourism is the view that preferences, beliefs, and other mental states in social-scientific theories are nothing but constructs re-describing people's behaviour. Mentalism is the view that they capture real phenomena, on a par with the unobservables in science, such as electrons and electromagnetic fields. While behaviourism has gone out of fashion in psychology, it remains influential in economics, especially in ‘revealed preference’ theory. We defend mentalism in economics, construed as a positive science, and show that it fits best scientific practice. (...) We distinguish mentalism from, and reject, the radical neuroeconomic view that behaviour should be explained in terms of brain processes, as distinct from mental states. (shrink)

There are many possible ways to approach the topic of educational theory and critique. One could inquire into the meaning of critical phenomena and subject-matter in practical education and instruction, investigate the various forms of critique with the goal of determining the extent to which they assist in clarifying pedagogical action, or one could ask: ‘What is meant by critical educational research?’ and ‘How do the various approaches to this topic relate to one another?’. This article inquires into the relationship (...) between critique and negativity. Such a distinction is relevant for the practical, theoretical and research-oriented use of the various forms and subject matters of critique. This analysis of their relationship aims to clarify how the structure of human learning connects to that of pedagogical action; and, additionally, how the theoretical guidelines and orientation for pedagogical action relate to scientific analyses and research in education in a way that is productive. Distinctions made in thought, judgement and action are not simply delimiting positive characteristics. Such distinctions are at once mediated by the relations of knowledge and ignorance, ability and inability. Although ignorance and inability can be transformed into positive knowledge and ability, they are not superseded in the process. Ignorance and inability are, on the contrary, constitutive elements of learning. The possibility for transitions from ignorance and inability to knowledge and ability—a possibility that itself presupposes knowledge and ability—point to a form of negativity within the process of education (Bildung). This form of negativity relates to the human ability to learn (Bildsamkeit) and provides the definitive basis of human learning. A form of negativity constitutive of learning processes leads to one that grounds pedagogical processes. Pedagogical efficacy is mediated by a double negativity, comprised of both a universal and a particular form of negativity. The relation of negativity to learning and pedagogical efficacy, with specific reference to educational research studies on teaching and learning processes, is considered. A form of educational research that operates beyond fundamentalist criticisms—that is to say, criticisms based on unshakeable beliefs—and utilises issues arising from a pluralisation of critique to confront the pluralism of critical positions, is considered. The article closes with reflections on the relation between the Critical and the Uncritical. (shrink)

We introduce a “reason-based” framework for explaining and predicting individual choices. It captures the idea that a decision-maker focuses on some but not all properties of the options and chooses an option whose motivationally salient properties he/she most prefers. Reason-based explanations allow us to distinguish between two kinds of context-dependent choice: the motivationally salient properties may (i) vary across choice contexts, and (ii) include not only “intrinsic” properties of the options, but also “context-related” properties. Our framework can accommodate boundedly rational (...) and sophisticatedly rational choice. Since properties can be recombined in new ways, it also offers resources for predicting choices in unobserved contexts. (shrink)

All existing impossibility theorems on judgment aggregation require individual and collective judgment sets to be consistent and complete, arguably a demanding rationality requirement. They do not carry over to aggregation functions mapping profiles of consistent individual judgment sets to consistent collective ones. We prove that, whenever the agenda of propositions under consideration exhibits mild interconnections, any such aggregation function that is "neutral" between the acceptance and rejection of each proposition is dictatorial. We relate this theorem to the literature.

Which rules for aggregating judgments on logically connected propositions are manipulable and which not? In this paper, we introduce a preference-free concept of non-manipulability and contrast it with a preference-theoretic concept of strategy-proofness. We characterize all non-manipulable and all strategy-proof judgment aggregation rules and prove an impossibility theorem similar to the Gibbard--Satterthwaite theorem. We also discuss weaker forms of non-manipulability and strategy-proofness. Comparing two frequently discussed aggregation rules, we show that “conclusion-based voting” is less vulnerable to manipulation than “premise-based voting”, (...) which is strategy-proof only for “reason-oriented” individuals. Surprisingly, for “outcome-oriented” individuals, the two rules are strategically equivalent, generating identical judgments in equilibrium. Our results introduce game-theoretic considerations into judgment aggregation and have implications for debates on deliberative democracy. (shrink)

Recently, a number of philosophers of biology have endorsed views about random drift that, we will argue, rest on an implicit assumption that the meaning of concepts such as drift can be understood through an examination of the mathematical models in which drift appears. They also seem to implicitly assume that ontological questions about the causality of terms appearing in the models can be gleaned from the models alone. We will question these general assumptions by showing how the same equation (...) — the simple 2 = p2 + 2pq + q2 — can be given radically different interpretations, one of which is a physical, causal process and one of which is not. This shows that mathematical models on their own yield neither interpretations nor ontological conclusions. Instead, we argue that these issues can only be resolved by considering the phenomena that the models were originally designed to represent and the phenomena to which the models are currently applied. When one does take those factors into account, starting with the motivation for Sewall Wright’s and R.A. Fisher’s early drift models and ending with contemporary applications, a very different picture of the concept of drift emerges. On this view, drift is a term for a set of physical processes, namely, indiscriminate sampling processes. (shrink)

We describe the growth of interest in the ethics of research with human participants based on articles abstracted in Psychological Abstracts and PsycLZT. Interest was low and variable until 1974, after which there was a marked increase in the number of articles published. We explain this emergence of ethical interest in terms of the social climate of concern for human rights in the 1960s and 1970s, the 1973 revision of the American Psychological Association's ethical principles, and the development of federal (...) regulation of research with human participants.

Musica Poetica provides an unprecedented examination of the development of Baroque musical thought. The initial chapters, which serve as an introduction to the concept and teachings of musical-rhetorical figures, explore Martin Luther's theology of music, the development of the Baroque concept of musica poetica, the idea of the affections in German Baroque music, and that music's use of the principles and devices of rhetoric. Dietrich Bartel then turns to more detailed considerations of the musical-rhetorical figures that were developed in (...) Baroque treatises and publications. After brief biographical sketches of the major theorists, Bartel examines those theorists' interpretation and classification of the figures. The book concludes with a detailed presentation of the musical-rhetorical figures, in which each theorist's definitions are presented in the original language and in parallel English translations. Bartel's clear, detailed analysis of German Baroque musical-rhetorical figures, combined with his careful translations of interpretations of those figures from a wide range of sources, make this book an indispensable introduction and resource for all students of Baroque music. Dietrich Bartel is an associate professor in the Department of Music at Canadian Mennonite Bible College (affiliated with University of Manitoba). (shrink)
