We posit a key goal of firms’ corporate social responsibility efforts is to influence reputation through carefully crafted communicative practices. This trend has accelerated with the rise of social media such as Twitter and Facebook, which are essentially public message networks that organizations are leveraging to engage with concerned audiences. Given the large number of messages sent on these sites, only some will be effective and achieve broad public resonance. Building on signaling theory, this paper asks whether and how messages (...) conveying CSR-related topics resonate with the public and, if so, which CSR topics and signal qualities are most effective. We test our hypotheses using data on public reactions to Fortune 500 companies’ CSR-focused Twitter feeds, using the retweeting of firms’ messages as a proxy for public resonance. We find resonance is positively associated with messages that convey CSR topics such as the environment or education, those that make the topic explicit through use of hashtags, and those that tap into existing social movement discussions.

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.

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)

Advancements in biological ageing research have shown that age-related diseases may be fought more effectively in the future by directly intervening into the ageing process. This prospect is associated with hopes for solving problems of demographic change. It also addresses raising awareness for complex ethical, legal and social issues that have hardly been a topic of discussion to date. Therefore, as the objective of our project, an interdisciplinary discourse module entitled “Ethics of Biogerontology” was developed to initiate a social debate (...) on the ethical, legal, and societal implications of biogerontology. The discourse module focuses on competences and argumentation skills and was developed with experts from relevant disciplines, e.g. biogerontology, social gerontology, philosophy, geriatrics, and medical ethics. Concepts of age and ageing are tightly interlinked with biogerontology and are as such relevant as teaching contents of the discourse module. The course module was tested in eight discourse teaching projects in research, medicine, and education in various partner institutions and evaluated based on an ethical competence model. This article describes the conception, including the learning objectives, of such a teaching course and the associated teaching contents. It also gives a justification for their selection. Finally, we summarize the results of the evaluation. (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)

The physiological blind spot corresponds to the optic disc where the retina contains no light-detecting photoreceptor cells. Our perception seemingly fills in this gap in input. Here we suggest that rather than an active process, such perceptual filling-in could instead be a consequence of the integration of visual inputs at higher stages of processing discounting the local absence of retinal input. Using functional brain imaging, we resolved the retinotopic representation of the physiological blind spot in early human visual cortex and (...) measured responses while participants perceived filling-in. Responses in early visual areas simply reflected the absence of visual input. In contrast, higher extrastriate regions responded more to stimuli in the eye containing the blind spot than the fellow eye. However, this signature was independent of filling-in. We argue that these findings agree with philosophical accounts that posit that the concept of filling-in of absent retinal input is unnecessary. (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)

This is the initial volume in a new series entitled Ars medicinae: The Science of Medicine and Human Salvation. The name of the association behind the series is Initiative Gesundheit, which is made up of physicians, researchers, and university teachers working in the sciences and the humanities. This first publication is designed to reflect the broad range of subjects to be addressed in the volumes to come, the immense variety of which has prompted the editors to opt for a format (...) that will do justice to this multiplicity.The leitmotif for the first installment is "health," a concept that both delineates the boundaries of the topics envisaged and provides an introduction to the issues and problems involved.In line with the interdisciplinary approach adopted by Initiative Gesundheit, the essays assembled in this volume approach the subject from the perspectives of medicine, medical history, philosophy, theology, and philology. Historically, the purview extends from antiquity to the present day. (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)

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)

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)

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)
