Disjunctive Quantum Logic in Dynamic Perspective

In Coecke (2002) we proposed the intuitionistic or disjunctive representation of quantum logic, i.e., a representation of the property lattice of physical systems as a complete Heyting algebra of logical propositions on these properties, where this complete Heyting algebra goes equipped with an additional operation, the operational resolution, which identifies the properties within the logic of propositions. This representation has an important application towards dynamic quantum logic, namely in describing the temporal indeterministic propagation of actual properties of physical systems. This paper can as such by conceived as an addendum to Quantum Logic in Intuitionistic Perspective that discusses spin-off and thus provides an additional motivation. We derive a quantaloidal semantics for dynamic disjunctive quantum logic and illustrate it for the particular case of a perfect (quantum) measurement.

The Clown's Use of Empathy: An Interview with Bob Berky

Excerpts from an interview with Bob Berky reveal the clown's keen understanding of empathic attunement, what psychotherapists, pastoral counselors, and persons in pastoral care maintain is a vital correspondence toward authentic interpersonal presence. Berky discusses the use of silence and movement to free the individual with whom he invites to his stage from rigid personas and limiting preconceptions. He underscores the life-giving possibilities of the laugh of recognition—the realization that we share a kindred experience of being human, and can release our unique potentials toward creative connection and difference.     

When “All the Five Circles” are Four: New Exercises in Domain Restriction

The domain of a quantifier is determined by a variety of factors, which broadly speaking fall into two types. On the one hand, the context of utterance plays a role: if the focus of attention is on a particular collection of kangaroos, for example, then “Q kangaroos” is likely to range over the individuals in that set. On the other hand, the utterance itself will help to establish the quantificational domain, inter alia through presuppositions triggered within the sentence. In this paper, we concentrate our attention on constructions like the following, in which “the square to which ... ” is the critical presupposition trigger:

1. (i)
   Q circles ...
    
2. (ii)
   Q of these circles ...
    
3. (iii)
   Q of these five circles ... ... have the same colour as the square to which they are connected.
    

Many theories predict that all instances of these schemata will give rise to the presupposition that every circle is connected to a square. We present an analysis which predicts that these sentences should generally be accepted in a context in which not all the circles are connected to a square, with one exception only: if a quantified sentence is of type (iii) and Q is non-intersective, then the sentence should be more likely to be rejected. Furthermore, we predict that manipulating the context so as to make the connected circles more or less salient should have an effect on statements with non-intersective quantifiers only. These predictions were tested in a series of experiments.     

Mapping grief: A study in practice using a quantitative and qualitative approach to exploring and addressing the range of responses to loss

The Adult Attitude to Grief (AAG) scale was devised for an earlier study (Machin, 2001) to test the validity of a concept of loss, which proposed that grief reactions fall broadly into three categories — ‘overwhelmed’, ‘balanced’ and ‘controlled’. There was statistical support for the proposed differences but the AAG scale, more importantly, provided insight into the diverse reactions taking place in individual bereaved respondents. This paper describes a second study undertaken to examine the clinical usefulness of the AAG scale with clients receiving help within the Psychological Services Operating Unit of the North Staffordshire Combined Healthcare (NHS) Trust. The scale has been used both in its original form with bereaved clients and in a modified form with clients having distress symptoms associated with other losses, such as relationship breakdown or the onset of chronic illness. The use of the AAG scale in this clinical setting suggests that, both as an assessment tool and as a cue for therapeutic dialogue, it provides a promising way of mapping the general and particular characteristics of response to loss in individual clients. Consideration is also given to varying therapeutic approaches needed to help clients regain the equilibrium disturbed by their grief.     

In Defence of Backyard Chickens

Suppose that animals have rights. If so, may you go down to your local farm store, buy some chicks, raise them in your backyard, and eat their eggs? You wouldn't think so. But we argue, to the contrary, that you may. Just as there are circumstances in which it's permissible to liberate a slave, even if that means paying into a corrupt system, so there are circumstances in which it's permissible to liberate chickens by buying them. Moreover, we contend that restrictions on freedom of movement can be appropriate for chickens, but not humans, because of the obvious differences between the interests of healthy, adult humans versus those of chickens who have been bred for human use. We also argue that egg consumption is permissible based on the plausible assumption that no one's rights are violated in their consumption, and so while there may sometimes be morally preferable uses for eggs, you do nothing unjust in eating them. If we're right, then the rights view doesn't imply that veganism is obligatory; rather, it implies that the constraints on how we source animal products, though highly demanding, are not so demanding that they can't be met.     

The effects of context change on long-term habituation of the orienting response in humans

Four experiments examined the effects of context change (Experiments 1-3) and context extinction (Experiment 4) on long-term habituation of the skin conductance response. In all experiments, subjects received 15 presentations of a target stimulus in each of two sessions. In Experiment 1 (N=60) there was a 15-min interval between training and test sessions. This interval was extended to 24 hours in Experiments 2 (N=60) and 3 (N=60). The experimental treatment in each of these studies involved a change in context between the two training sessions. None of the experiments provided evidence of context dependency in measures of long-term habituation. In Experiment 4 (N=60) experimental subjects received a period of context extinction during which they remained in the laboratory environment between two series of habituation trials. Again, however, there was no evidence that long-term habituation was contextually mediated. Thus, the results fail uniformly to support theories that argue that long-term habituation is context-dependent.
