Disorders of consciousness pose a substantial ethical challenge to clinical decision making, especially regarding the use of life-sustaining medical treatment. For these decisions it is paramount to know whether the patient is aware or not. Recent brain research has been striving to assess awareness by using mainly functional magnetic resonance imaging. We review the neuroscientific evidence and summarize the potential and problems of the different approaches to prove awareness. Finally, we formulate the crucial ethical questions and outline the different articles (...) in this special issue on disorders of consciousness. (shrink)
Se indaga la relación que se da en la República entre los dos significados de ousia: como propiedad en el sentido de posesiones y riqueza, o en el sentido de esencia o sustancia. Aparte de las relaciones económicas asociadas al préstamo, al intercambio y al interés, se examina la función que, respecto de la ousia, cumple la moneda en la economía como recurso para disociar la riqueza de las posesiones, con lo cual logra un nivel de universalidad y equivalencia equiparable (...) al del propio ser. The article inquires into the relation established in the Republic between the two meanings of ousia: property in the sense of possessions and wealth, and essence or substance. Besides the economic relations associated with loans, exchange, and interest, the paper examines the role of currency in the economy, with respect to ousia, as a means of dissociating wealth from possessions, thus achieving a degree of universality comparable to that of being itself.

Neuroimaging studies on moral decision-making have thus far largely focused on differences between moral judgments with opposing utilitarian (well-being maximizing) and deontological (duty-based) content. However, these studies have investigated moral dilemmas involving extreme situations, and did not control for two distinct dimensions of moral judgment: whether or not it is intuitive (immediately compelling to most people) and whether it is utilitarian or deontological in content. By contrasting dilemmas where utilitarian judgments are counterintuitive with dilemmas in which they are intuitive, we (...) were able to use functional magnetic resonance imaging to identify the neural correlates of intuitive and counterintuitive judgments across a range of moral situations. Irrespective of content (utilitarian/deontological), counterintuitive moral judgments were associated with greater difficulty and with activation in the rostral anterior cingulate cortex, suggesting that such judgments may involve emotional conflict; intuitive judgments were linked to activation in the visual and premotor cortex. In addition, we obtained evidence that neural differences in moral judgment in such dilemmas are largely due to whether they are intuitive and not, as previously assumed, to differences between utilitarian and deontological judgments. Our findings therefore do not support theories that have generally associated utilitarian and deontological judgments with distinct neural systems. (shrink)
In this paper, it is argued the Stoics develop an account of corporeals that allows their theory of bodies to be, at the same time, a theory of causation, agency, and reason. The paper aims to shed new light on the Stoics' engagement with Plato's Sophist . It is argued that the Stoics are Sons of the Earth insofar as, for them, the study of corporeals - rather than the study of being - is the most fundamental study of reality. (...) However, they are sophisticated Sons of the Earth by developing a complex notion of corporeals. A crucial component of this account is that ordinary bodies are individuated by the way in which the corporeal god pervades them. The corporeal god is the one cause of all movements and actions in the universe. (shrink)
The tendency towards an increasing integration of the informational web into our daily physical world (in particular in so-called Ambient Intelligent technologies which combine ideas derived from the field of Ubiquitous Computing, Intelligent User Interfaces and Ubiquitous Communication) is likely to make the development of successful profiling and personalization algorithms, like the ones currently used by internet companies such as Amazon , even more important than it is today. I argue that the way in which we experience ourselves necessarily goes (...) through a moment of technical mediation. Because of this algorithmic profiling that thrives on continuous reconfiguration of identification should not be understood as a supplementary process which maps a pre-established identity that exists independently from the profiling practice. In order to clarify how the experience of one’s identity can become affected by such machine-profiling a theoretical exploration of identity is made (including Agamben’s understanding of an apparatus , Ricoeur’s distinction between idem - and ipse -identity, and Stiegler’s notion of a conjunctive–disjunctive relationship towards retentional apparatuses ). Although it is clear that no specific predictions about the impact of Ambient Intelligent technologies can be made without taking more particulars into account, the theoretical concepts are used to describe three general scenarios about the way wherein the experience of identity might become affected. To conclude, I argue that the experience of one’s identity may affect whether the cases of unwarranted discrimination resulting from ubiquitous differentiations and identifications within an Ambient Intelligent environment, will become a matter of societal concern.

The meanings of abstract concepts depend on context. Perceptual symbol systems (PSS) provide a powerful framework for representing such context. Whereas a few expected difficulties for simulations are consistent with empirical findings, the theory does not clearly predict simulations of specific abstract concepts in a testable way and does not appear to distinguish abstract noun concepts (like truth) from their stem concepts (such as true).
Recent research on moral decision-making has suggested that many common moral judgments are based on immediate intuitions. However, some individuals arrive at highly counterintuitive utilitarian conclusions about when it is permissible to harm other individuals. Such utilitarian judgments have been attributed to effortful reasoning that has overcome our natural emotional aversion to harming others. Recent studies, however, suggest that such utilitarian judgments might also result from a decreased aversion to harming others, due to a deficit in empathic concern and social (...) emotion. The present study investigated the neural basis of such indifference to harming using functional neuroimaging during engagement in moral dilemmas. A tendency to counterintuitive utilitarian judgment was associated both with ‘psychoticism’, a trait associated with a lack of empathic concern and antisocial tendencies, and with ‘need for cognition’, a trait reflecting preference for effortful cognition. Importantly, only psychoticism was also negatively correlated with activation in the subgenual cingulate cortex (SCC), a brain area implicated in empathic concern and social emotions such as guilt, during counterintuitive utilitarian judgments. Our findings suggest that when individuals reach highly counterintuitive utilitarian conclusions, this need not reflect greater engagement in explicit moral deliberation. It may rather reflect a lack of empathic concern, and diminished aversion to harming others. (shrink)
The notions of the cosmic city and the common law are central to early Stoic political thought. As Vogt shows, together they make up one complex theory. A city is a place governed by the law. Yet on the law pervading the cosmos can be considered a true law, and thus the cosmos is the only real city. A city is also a dwelling-place--in the case of the cosmos, the dwelling-place of all human beings. Further, a city demarcates who belongs (...) together as fellow-citizens. The thought that we should view all other human beings as belonging to us constitutes the core of Stoic cosmopolitanism. All human beings are citizens of the cosmic city in the sense of living in the world. But the demanding task of acquiring wisdom allows a person to become a citizen in the strict sense: someone who lives according to the law, as the gods do. The sage is the only citizen, relative, friend and free person; via these notions, the Stoics explore the political dimensions of the Stoic idea of wisdom. Vogt argues against two widespread interpretations of the common law--that it consists of rules, and that lawful action is what right reason prescribes. While she rejects the rules-interpretation, she argues that the prescriptive reason-interpretation correctly captures key ideas of the Stoics' theory, but misses the substantive side of their conception of the law. The sage fully understands what is valuable for human beings, and this makes her actions lawful. The Stoics emphasize the revisionary nature of their theory; whatever course of action perfect deliberation commands, even if it be cutting off one's limb and eating it, we should act on its command, and not be held back by conventional judgments.

We present a method for improving local coherence in German with a positive effect on automatically as well as human-generated texts. We demonstrate that local coherence crucially depends on which constituent occupies the initial position in a sentence. To support our hypothesis, we provide statistical evidence based on a corpus investigation and on results of an experiment with human judges. Additionally, we implement our findings in a generation module for determining the Vorfeld constituent automatically.
The gestural repertoire of captive gorillas contains the so-called “hand-on“ (or “pat-off“) gesture in which one animals puts its flat hand on top of another's head, which often leads to cessation of the receiver's previous activity. We investigate the origins of this gesture and developmental aspects of gesture creation. We further analyze gesture form and use in relation to the age of the sender with special consideration of the reaction of the receiver to better explain the function of the hand-on. (...) The focus of the study is to compare this gesture across different age groups in gorillas in regard to both production and reception and to get insights into possible origins of the gesture. (shrink)
In contrast to apes' seemingly sophisticated skill at producing pointing gestures referentially, the comprehension of other individual's pointing gestures as a source of indexical information seems to be less pronounced.One reason for apes' difficulty at comprehending pointing gestures might be that in former studies they were mainly confronted with human declarative pointing gestures, whereas apes have largely been shown to point imperatively and towards humans. In the present study bonobos, chimpanzees and orangutans were confronted with a conspecific's imperative pointing gesture (...) in a competitive context, therefore mirroring former studies that have investigated apes' skills at producing these gestures.However, apes in the present study did not use their conspecific's pointing gestures. Apes have been shown to use indexical information when provided noncommunicatively and to interpret other individuals' actions in terms of motives. Thus, it is discussed whether apes treat a pointing gesture as intentional act of indexical reference. (shrink)
The integration of perceived events with appropriate action usually requires more flexibility to result in adaptive responses than Hommel et al. report in their selective review. The need for hierarchies of function that can intervene and the existence of diverse mediating brain mechanisms can be illustrated by the non-adaptive expression in psychiatric illness of negative priming, blocking, and affective responses.
Schyns, Goldstone & Thibaut present reasonable arguments for feature creation in category learning. We argue, however, that they do not provide unequivocal evidence either for the necessity or for the occurrence of feature creation. In an effort to sharpen the debate, we take the stand that a fixed feature approach is to be preferred in the absence of compelling evidence.
Since the Public Library of Science launched its first open-access journals and the Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities has been released in 2003 and found enormous attention, the claim for open accessâto make publicly funded journal articles available for the publicâstarted to reach German scientists too. But still no experience has been made with electronic publishing in general and more specifically with open-access publishing. One consequence is that the potential capacity of open accessâthe (...) (inter) national and (trans) disciplinary visibility and accessibility of scientific outputâis not sufficiently used by German researchers. Ways to successfully establish an open-access journal are presented in this article by referring to Forum Qualitative Sozialforschung/Forum: Qualitative Social Research (FQS) as an example: after introducing the current state of FQS traditional and innovative ways of publishing are being discussed which had been employed while developing FQS and which helped FQS to become the most important electronic journal in the field of qualitative research.
