There is a clear tendency in contemporary political/legal thought to limit agency to individual agents, thereby denying the existence and relevance of collective moral agency in general, and corporate agency in particular. This tendency is ultimately rooted in two particular forms of individualism – methodological and fictive (abstract) – which have their source in the Enlightenment. Furthermore, the dominant notion of moral agency owes a lot to Kant whose moral/legal philosophy is grounded exclusively on abstract reason and personal autonomy, to (...) the detriment of a due recognition of the socio-historical grounds of moral social conduct.I shall argue that an adequate theory of responsibility is needed, which does not only take into account individual responsibility, but also collective and corporate responsibility, capable of taking into consideration society and its problems. Furthermore, corporations are consciously and carefully structured organisations with different levels of management and have clearly defined aims and objectives, a central feature upon which I shall be focussing in this paper.

After a discussion of the possible connections between quantum mechanics and consciousness, and an examination of the circumstances under which some properties of a macroscopic system may be described by a quantum mechanical wave function, we propose three types of experiments in which one may search for the possible existence of quantal interference in mental events.

In their simplest form, hybrid languages are propositional modal languages which can refer to states. They were introduced by Arthur Prior, the inventor of tense logic, and played an important role in his work: because they make reference to specific times possible, they remove the most serious obstacle to developing modal approaches to temporal representation and reasoning. However very little is known about the computational complexity of hybrid temporal logics.In this paper we analyze the complexity of the satisfiability problem of (...) a number of hybrid temporal logics: the basic hybrid language over transitive trees; nominal Until logic; and referential interval logic. We discuss the effects of including nominals, the @ operator, the somewhere modality E, and the difference operator D. Adding nominals to tense logic leads for several frame-classes to an increase in complexity of the satisfiability problem from PSPACE to EXPTIME. On transitive trees, however, the satisfiability problem for this language can be decided in PSPACE. Along the way we make a detour through hybrid propositional dynamic logic: we establish upper bounds for a number of temporal logics by generalizing results due to Passy and Tinchev [29] and De Giacomo [16]. We conclude with some remarks on the relevance of our results to description logic, and draw attention to the utility of the spypoint technique for proving upper and lower bounds. (shrink)

Autobiographical memory and the self are closely linked. AM retrieval in depression is characterized by a lack of specificity, suggesting an impairment of episodic AM. Autonoetic consciousness and self-perspective, which are critical to episodic AM, have never been addressed in depression. Twenty-one depressed inpatients and 21 matched controls were given an episodic AM task designed to assess positive and negative memories regarding specificity, autonoetic consciousness , and self-perspective . For specificity, “remember”, and “field” responses, ANOVAs revealed a main group effect (...) and a group × valence interaction. Between groups, patients showed lower scores than controls for positive memories. Within groups, patients showed greater scores for negative memories, and controls showed greater scores for positive memories. There is a global episodic AM impairment of positive memories in depression regarding specificity, autonoetic consciousness, and self-perspective. Our results suggest new cognitive interventions to improve the self-relevance of positive memories in depression. (shrink)

Recently, Brukner and Zeilinger 3354) have claimed that the Shannon information is not well defined as a measure of information in quantum mechanics, adducing arguments that seek to show that it is inextricably tied to classical notions of measurement. It is shown here that these arguments do not succeed: the Shannon information does not have problematic ties to classical concepts. In a further argument, Brukner and Zeilinger compare the Shannon information unfavourably to their preferred information measure, I , with regard (...) to the definition of a notion of “total information content.” This argument is found unconvincing and the relationship between individual measures of information and notions of “total information content” investigated. We close by considering the prospects of Zeilinger's Foundational Principle as a foundational principle for quantum mechanics. (shrink)

The abstract description of a physical system is developed, along lines originally suggested by Birkhoff and von Neumann, in terms of the complete lattice of propositions associated with that system, and the distinction between classical and quantum systems is made precise. With the help of the notion of state, a propositional system is defined: it is remarked that every irreducible propositional system (of more than three dimensions) is isomorphic to the lattice of all closed subspaces of a Hilbert space constructed (...) on some division ring with involution. The propositional system consisting of a family of separable complex Hilbert spaces is treated as a particular case which is sufficiently general to include both classical and quantum mechanics. The theory of the Galilean particle without spin is given as an illustration. Finally, the basis for the statistical interpretation of wave mechanics is developed with the help of Gleason's theorem. In an appendix, a proof of essentially the first part of Gleason's theorem is given which is a little different (perhaps more geometric) from that originally given by Gleason. (shrink)

In his own writings, Rawls purposively used only a loose characterization of the basic structure, but two prominent misinterpretations highlight the current need for a more detailed account. First, G.A. Cohen argues that the Rawlsian focus on the basic structure is arbitrary due to the Rawlsian appeal to profound effects. Second, some theorists conflate the justification of coercion with the assessment of a basic structure by defining the basic structure as the coercive structure. Both misinterpretations can be corrected by carefully (...) specifying what social institutions are and explaining which social institutions come together to form the basic structure of society.

A defining characteristic of Alzheimer’s disease is difficulty in retrieving semantic memories, or memories encoding facts and knowledge. While it has been suggested that this impairment is caused by a degradation of the semantic store, the precise ways in which the semantic store is degraded are not well understood. Using a longitudinal corpus of semantic fluency data, we derive semantic network representations of patients with Alzheimer’s disease and of healthy controls. We contrast our network-based approach with analyzing fluency data with (...) the standard method of counting the total number of items and perseverations in fluency data. We find that the networks of Alzheimer’s patients are more connected and that those connections are more randomly distributed than the connections in networks of healthy individuals. These results suggest that the semantic memory impairment of Alzheimer’s patients can be modeled through the inclusion of spurious associations between unrelated concepts in the semantic store. We also find that information from our network analysis of fluency data improves prediction of patient diagnosis compared to traditional measures of the semantic fluency task. (shrink)

The academic literature in research ethics has been marked in the past decade by a much broader focus on the need for the protection of developing communities subjected to international clinical trials. Because of the proximity of the revision of the Declaration of Helsinki, completed in October 2008, most papers have addressed the issue of a double standard of care following the use of placebo. However, other no less important issues, such as interactions between the lifestyles structures of low-income communities (...) and the efficiency of risk-minimising procedures also deserve attention. The purpose of this paper is to discuss forms of uncertainty involved in clinical trials in poor and low-income countries that are not addressed by conventional methods of risk assessment. Furthermore, the increase in size of risks that are identified by conventional assessment methods will be addressed. Besides, the difficulty in properly applying risk-minimising procedures will be discussed. Finally, this paper proposes the involvement of research ethics committees in the risk evaluation process and the establishment of national ethics evaluation systems. (shrink)

We re-express a previous general result in a way which seems easier to remember, using the terminology of infinite games. We show how this can be applied to construct recursive linear orderings, showing, for example, that if there is a ▵ 0 2β + 1 linear ordering of type τ, then there is a recursive ordering of type ω β · τ.

We extend results of Harizanov and Barker. For a relation R on a recursive structure /oA, we give conditions guaranteeing that the image of R in a recursive copy of /oA can be made to have arbitrary ∑α0 degree over Δα0. We give stronger conditions under which the image of R can be made ∑α0 degree as well. The degrees over Δα0 can be replaced by certain more general classes. We also generalize the Friedberg-Muchnik Theorem, giving conditions on a pair (...) of relations R and S under which the images of R and S can be made ∑α0 and independent over Δα0 in a recursive copy of /oA.

Chalmers' (2018) meta-problem of consciousness emphasizes unexpected common ground between otherwise incompatible positions. We argue that the materialist should welcome discussion of the meta-problem. We suggest that the core of the metaproblem is the seeming arbitrariness of subjective experience. This has an unexpected resolution when one moves to an interventionist account of scientific explanation: the same interventions that resolve the hard problem should also resolve the meta-problem.

In the majority of academic institutions nursing and medical students receive a traditional education, the content of which tends to be specific to their future roles as health care professionals. In essence, each curriculum design is independent of each course. Over the last decade, however, interest has been accumulating in relation to interprofessional and multiprofessional learning at student level. With the view that learning together during their student training would not only encourage and strengthen future collaboration in practice settings but (...) also enhance patient care, the University of Dundee decided to run a pilot study to explore shared teaching in ethics between medical and nursing students. This article presents a report on the reasons for selecting health care ethics as a precursor for shared teaching, the educational tool used for the sessions, and the results of student and facilitator evaluation of the short course. Overall, despite problems such as poor attendance by some students, and facilitation and timetable difficulties, most of the feedback from students and facilitators has been positive. In essence the ‘idea’ has gone from strength to strength and there are now three levels of shared teaching in ethics between nursing and medical students, with plans to include further sessions with students from other disciplines. Within the text, ‘health care ethics’ will be referred to as ‘ethics’; nursing students/nurses encompasses midwifery students/midwives. (shrink)
