Goethe's objections to Newton's theory of light and colours are better than often acknowledged. You can accept the most important elements of these objections without disagreeing with Newton about light and colours. As I will argue, Goethe exposed a crucial weakness of Newton's methodological self-assessment. Newton believed that with the help of his prism experiments, he could prove that sunlight was composed of variously coloured rays of light. Goethe showed that this step from observation to theory is more problematic than (...) Newton wanted to admit. By insisting that the step to theory is not forced upon us by the phenomena, Goethe revealed our own free, creative contribution to theory construction. And Goethe's insight is surprisingly significant, because he correctly claimed that all of the results of Newton's prism experiments fit a theoretical alternative equally well. If this is correct, then by suggesting an alternative to a well-established physical theory, Goethe developed the problem of underdete... (shrink)

Infants can see someone pointing to one of two buckets and infer that the toy they are seeking is hidden inside. Great apes do not succeed in this task, but, surprisingly, domestic dogs do. However, whether children and dogs understand these communicative acts in the same way is not yet known. To test this possibility, an experimenter did not point, look, or extend any part of her body towards either bucket, but instead lifted and shook one via a centrally pulled (...) rope. She did this either intentionally or accidentally, and did or did not address her act to the subject using ostensive cues. Young 2-year-old children but not dogs understood the experimenter’s act in intentional conditions. While ostensive pulling of the rope made no difference to children’s success, it actually hindered dogs’ performance. We conclude that while human children may be capable of inferring communicative intent from a wide variety actions, so long as these actions are performed intentionally, dogs are likely to be less flexible in this respect. Their understanding of communicative intention may be more dependent upon bodily markers of communicative intent, including gaze, orientation, extended limbs, and vocalisations. This may be because humans have come under selective pressure to develop skills for communicating with absent interlocutors – where bodily co-presence is not possible. (shrink)

Wilson et al. focus on one class of AGL tasks: the cognitively demanding task of detecting non‐adjacent dependencies (NADs) among items. They provide a typology of the different types of NADs in natural languages and in AGL tasks. A range of cues affect NAD learning, ranging from the variability and number of intervening elements to the presence of shared prosodic cues between the dependent items. These cues, important for humans to discover non‐adjacent dependencies, are also found to facilitate NAD learning (...) in several nonhuman animal species. (shrink)

About one third of patients with epilepsy have seizures refractory to the medical treatment. Electrical stimulation mapping is the gold standard for the identification of “eloquent” areas prior to resection of epileptogenic tissue. However, it is time-consuming and may cause undesired side effects. Broadband gamma activity recorded with extraoperative electrocorticography during cognitive tasks may be an alternative to ESM but until now has not proven of definitive clinical value. Considering their role in cognition, the alpha and beta bands could further (...) improve the identification of eloquent cortex. We compared gamma, alpha and beta activity, and their combinations for the identification of eloquent cortical areas defined by ESM. Ten patients with intractable focal epilepsy participated in a delayed-match-to-sample task, where syllable sounds were compared to visually presented letters. We used a generalized linear model approach to find the optimal weighting of each band for predicting ESM-defined categories and estimated the diagnostic ability by calculating the area under the receiver operating characteristic curve. Gamma activity increased more in eloquent than in non-eloquent areas, whereas alpha and beta power decreased more in eloquent areas. Diagnostic ability of each band was close to 0.7 for all bands but depended on multiple factors including the time period of the cognitive task, the location of the electrodes and the patient’s degree of attention to the stimulus. We show that diagnostic ability can be increased by 3–5% by combining gamma and alpha and by 7.5–11% when gamma and beta were combined. We then show how ECoG power modulation from cognitive testing can be used to map the probability of eloquence in individual patients and how this probability map can be used in clinical settings to optimize ESM planning. We conclude that the combination of gamma and beta power modulation during cognitive testing can contribute to the identification of eloquent areas prior to ESM in patients with refractory focal epilepsy.

Whilst the academic literature on leadership has identified authenticity as an important leadership attribute, few studies have examined how authentic leadership is evaluated in naturally occurring discourse. This article explores how authentic leadership was characterised and evaluated in the discourse of the British press during the 2015 Labour Party leadership election—won, against the odds, by veteran left-winger Jeremy Corbyn. Using membership categorisation analysis, we show that the media discourse about authentic leadership was both ambiguous and ambivalent. In their representation of (...) authentic leadership, we found that a discourse of ‘ethical’ leadership was played out in tension with a discourse of ‘effective’ leadership. We propose that this complex and contradictory discursive landscape is also relevant in business contexts where ‘ethical’ leaders are subjected to praise for their virtues but also criticism for their ineffectiveness. Future research could usefully study how ‘ethical’ leaders in different settings can be subject to competing evaluations when their ethical values are discursively contrasted to expectations concerning what it takes to be an ‘effective’ leader.

Sociology has largely followed Durkheim’s lead in ignoring the question: why do people die by suicide? This negation prioritizes a positivist, structuralist approach and stymies sociology’s contribution by closing off a wide range of tools sociologists might employ. An interpretivist turn in suicide studies accompanied by the growing adoption of qualitative methodology has opened up an array of opportunities to produce insights lost in a Durkheimian approach, but has yet to confront their own weaknesses. This paper shows we need not (...) abandon either tradition, advocating for a third path that integrates the strengths of both approaches. (shrink)

Recently, βIII spectrins have been recognized as ataxia disease genes, with the identification by Ikeda and co‐workers of pathogenic mutations in the SPTBN2 gene in three large (and mapped) SCA5 families of American and European origin.(1) With their discovery, the large “Lincoln” family has been traced back to the underlying genetic defect for the slowly progressive cerebellar ataxia. In addition, the involvement of this component of the cytoskeleton directs attention towards the possible role of organelle stability during neurodegeneration. The findings (...) suggest that the mechanical properties of neurons and their dynamics may be as important as altered Ca2+ homeostasis, transcriptional dysregulation, and impaired protein degradation in neurodegeneration conditions.

Cosmological narratives like the creation story in the book of Genesis or the modern Big Bang are popularly understood to be descriptions of how the universe was created. However, cosmologies also say a great deal more. Indeed, the majority of cosmologies, ancient and modern, explore not simply how the world was made but how humans relate to their surrounding environment and the often thin line which separates humans from gods and animals. Combining approaches from classical studies, anthropology, and philosophy, this (...) book studies three competing cosmologies of the early Greek world: Hesiod's Theogony; the Orphic Derveni theogony; and Protagoras' creation myth in Plato's eponymous dialogue. Although all three cosmologies are part of a single mythic tradition and feature a number of similar events and characters, Olaf Almqvist argues they offer very different answers to an ongoing debate on what it is to be human. Engaging closely with the ontological turn in anthropology and in particular with the work of Philippe Descola, this book outlines three key sets of ontological assumptions - analogism, pantheism, and naturalism - found in early Greek literature and explores how these competing ontological assumptions result in contrasting attitudes to rituals such as prayer and sacrifice.

In this article the authors focus on the emergence, or disappearance, of notions of responsibility in social dynamic processes. Hence, the starting point in this article is concrete behavior within organisational settings. This article presents a systematic overview of mechanisms related to acting upon a sense of moral responsibility. Some of these mechanisms are based on individual characteristics, others are embedded in the social context wherein responsible behaviour emerges or disappears. In this article, various mechanisms are identified and labelled in (...) order to analyse what types of processes are behind the mechanisms. In this way, the article yields important understandings for the conscious use of these mechanisms to strengthen responsible behavior within organisations. (shrink)

Theory of illness causation is an important issue in all biomedical sciences, and solid etiological explanations are needed in order to develop therapeutic approaches in medicine and preventive interventions in public health. Until now, the literature about the theoretical underpinnings of illness causation research has been scarce and fragmented, and lacking a convenient summary. This interdisciplinary book provides a convenient and accessible distillation of the current status of research into this developing field, and adds a personal flavor to the discussion (...) by proposing the etiological stance as a comprehensive approach to identify modifiable causes of illness.

Randolph Bourne was only thirty-two when he died in 1918, but he left a legacy of astonishingly mature and incisive writings on politics, literature, and culture, which were of enormous influence in shaping the American intellectual climate of the 1920s and 1930s. This definitive collection, back in print at last, includes such noted essays as "The War and the Intellectuals," "The Fragment of the State," "The Development of Public Opinion," and "John Dewey's Philosophy." Bourne's critique of militarism and advocacy of (...) cultural pluralism are enduring contributions to social and political thought, sure to have an equally strong impact in our own time. In their introduction and preface, Olaf Hansen and Christopher Lasch provide biographical and historical context for Bourne's work. (shrink)

Many kinds of complex systems exhibit characteristic patterns of temporal correlations that emerge as the result of functional interactions within a structured network. One such complex system is the brain, composed of numerous neuronal units linked by synaptic connections. The activity of these neuronal units gives rise to dynamic states that are characterized by specific patterns of neuronal activation and co-activation. These patterns, called functional connectivity, are possible neural correlates of perceptual and cognitive processes. Which functional connectivity patterns arise depends (...) on the anatomical structure of the underlying network, which in turn is modified by a broad range of activity-dependent processes. Given this intricate relationship between structure and function, the question of how patterns of anatomical connectivity constrain or determine dynamical patterns is of considerable theoretical importance. The present study develops computational tools to analyze networks in terms of their structure and dynamics. We identify different classes of network, including networks that are characterized by high complexity. These highly complex networks have distinct structural characteristics such as clustered connectivity and short wiring length similar to those of large-scale networks of the cerebral cortex.

The Cognitive Decathlon is a proposed set of tasks that can be tested on both human and artificially intelligent agents, and which constitutes a modern specification for the Turing Test. In this paper, a partial implementation of the Cognitive Decathlon is described using the Psychology Experiment Building Language (PEBL). The tasks focus not simply on generic human abilities, but on critical skills that highlight aspects of human performance that are at odds with common artificial intelligence approaches. The differences between human (...) and algorithmic behavior in such tasks can reveal properties of the human cognitive architecture, and production of similar behavior by artificial systems can help constrain and validate biologically-inspired systems.

In this essay, I argue that Ted Poston's theory of explanatory coherentism is well-suited as a tool for causal explanation in the health sciences, particularly in epidemiology. Coherence has not only played a role in epidemiology for more than half a century as one of Hill's viewpoints, it can also provide background theory for the development of explanatory systems by integrating epidemiologic evidence with a diversity of other error-independent data. I propose that computational formalization of Hill's viewpoints in an explanatory (...) coherentist framework would provide an excellent starting point for a formal epistemological (knowledge-theoretical) project designed to improve causal explanation in the health sciences. As an example, I briefly introduce Paul Thagard's ECHO system and offer my responses to possible objections to my proposal. (shrink)

Models of illness causation play a crucial role in medicine and public health. In their recent paper on this topic, Michael Kelly, Rachel Kelly, and Federica Russo state that the integration of social, biological, and behavioral causes in one and the same etiologic mechanism remains to be clarified. In particular, they think that current models of illness causation do not appreciate "the truly integrated nature of bio-social-behavioral pathogenesis". In brief, Kelly, Kelly, and Russo suggest that two levels of explanation are (...) at work in medicine and public health, biological and social; that integration is difficult because of resistance to including social determinants of disease in both the...

Are we perhaps in the "matrix", or anyway, victims of perfect and permanent computer simulation? No. The most convincing—and shortest—version of Putnam's argument against the possibility of our eternal envattment is due to Crispin Wright (1994). It avoids most of the misunderstandings that have been elicited by Putnam's original presentation of the argument in "Reason, Truth and History" (1981). But it is still open to the charge of question-begging. True enough, the premisses of the argument (disquotation and externalism) can be (...) formulated and defended without presupposing external objects whose existence appears doubtful in the light of the very skeptical scenario which Putnam wants to repudiate. However, the argument is only valid if we add an extra premiss as to the existence of some external objects. In order to avoid circularity, we should run the argument with external objects which must exist even if we are brains in a vat, e.g. with computers rather than with trees. As long as the skeptic is engaged in a discussion of the brain-in-a-vat scenario, she should neither deny the existence of computers nor the existence of causal relations; for if she does, she is in fact denying that we are brains in a vat.

This paper contributes to the (re-)conceptualisation of responsible innovation by proposing an evolutionary economic approach that focuses on the role of consumers in the innovation process. After a discussion of the philosophical foundations and ethical implications of this approach, which bears an explanatory potential that has not been adequately considered in previous discussions of responsible innovation, we present a first step towards capturing the important but often neglected role of consumers in innovation processes (including responsible innovation): We propose an agent-based (...) model that incorporates a multidimensional space of characteristics in which new products or services are represented by more than the mere aspect of price and quality. Instead, innovations are denoted by a large set of characteristics, including also negative or harmful ones. The model is used to illustrate that consumers’ heterogeneity and bounded rationality – even if considered in a simple manner – indeed play a crucial role in the creation and diffusion of responsible innovation which can and should be used for further work in this field and for possible extensions of the model.

Two things about Hilary Putnam have not changed throughout his career: some (including Putnam himself) have regarded him as a “realist” and some have seen him as a philosopherwho changed his positions (certainly with respect to realism) almost continually. Apparently, what realism meant to him in the 1960s, in the late seventies and eighties, and in the nineties, respectively, are quite different things. Putnam indicates this by changing prefixes: scientific, metaphysical, internal, pragmatic, commonsense, but always realism. Encouraged by Putnam’s own (...) attempts to distinguish his views from one time to another, his work is often regarded as split between an early period of “metaphysical realism” (his characterization) and a later and still continuing period of “internal realism”. Late Putnam is understood to be a view that insists on the primacy of our practices, while the early period is taken to be a view from outside these, a “God’s Eye view”. As Putnam himself stresses (1992b), this way of dividing his work obscures continuities, the most important of which is a continuing attempt to understand what is involved in judging practices of inquiry, like science, as being objectively correct. Thus Putnam’s early and his current work appear to have more in common than the division between “early” and “late” suggests. In fact, Putnam’s earlier writings owe much of their critical force to his adopting the pragmatic perspective of an open-minded participant in practices of empirical inquiry, a stance not explicitly articulated in these writings but rather taken simply as a matter of course.1 Thus insofaras Putnam’s early writings defend a form of representational realism, they can be regarded as attempts to articulate a realist position at work inside our ordinary practices of making empirical judgments. For this reason, we begin our review of Putnam’s realisms by extracting from the early writings a core of principles that carries over into his current work but underwent significantly different interpretations over time..

It is shown that the method of operationaldefinition of theoretical terms applied inphysics may well support constructivist ideasin cognitive sciences when extended toobservational terms. This leads to unexpectedresults for the notion of reality, inductionand for the problem why mathematics is sosuccessful in physics.A theory of cognitive operators is proposedwhich are implemented somewhere in our brainand which transform certain states of oursensory apparatus into what we call perceptionsin the same sense as measurement devicestransform the interaction with the object intomeasurement results. Then, (...) perceivedregularities, as well as the laws of nature wewould derive from them can be seen asinvariants of the cognitive operators concernedand are by this human specific constructsrather than ontologically independent elements.. So, reality in so far it isrepresented by the laws of nature has no longeran independent ontological status. This isopposed to Campbell's `natural selectionepistemology'. From this it is shown that thereholds an incompleteness theorem for physicallaws similar to Gödels incompletenesstheorem for mathematical axioms, i.e., there isno definitive or object `theory of everything'.This constructivist approaches to cognitionwill allow a coherent and consistent model ofboth cognitive and organic evolution. Whereasthe classical view sees the two evolutionrather dichotomously. (shrink)

The intention of the article is to offer stakeholders affected by mergers a criterion from which moral arguments may be generated for the organization of each individual case. The criterion: "Any operation causing legitimate interests to suffer vital infringement should be avoided in a merger process." A vital infringement of these interests is assumed when the merger undermines unique positive opportunities or considerable impairment in the future, impossible to overcome for the person affected without an unacceptable level of difficulty. Therefore, (...) we mainly concentrate on implicit contracts – which should be based on the principle pacta sunt servanda as well. These contracts are mandatory to run an economy that produces increasingly more knowledge-based goods. (shrink)

The aim of this paper is to reconcile the two modes of description of macrosystems, i.e., to remove certain inconsistencies between the classical phenomenological and the quantum-theoretical descriptions of a macrosystem. Starting from Ludwig's formulation of a general framework for classical theories and his ansatz for a compatibility condition between the quantum theoretical and the classical mode of description for a macrosystem, we try to make clear what the “classical content” of many-body quantum theory really is. It is shown that (...) this classical content may be described by a certain “observable,” i.e., an operator-valued measure over the Borel sets of the classical trajectory space. There exists a reduced time evolution within this classical content which has the structure of a true semigroup in case of an irreversible classical time evolution. (shrink)
