General considerations of matter coupling with the self-dual connection
It has been shown for low-spin fields that the use of only the self-dual part
of the connection as basic variable does not lead to extra conditions or
inconsistencies. We study whether this is true for more general chiral action.
We generalize the chiral gravitational action, and assume that half-integer
spin fields are coupled with torsion linearly. The equation for torsion is
solved and substituted back into the generalized chiral action, giving
four-fermion contact terms. If these contact terms are complex, the imaginary
part will give rise to extra conditions for the gravitational and matter field
equations. We study the four-fermion contact terms taking spin-1/2 and spin-3/2
fields as examples.Comment: 16 pages, late
Synthetic cannabinoids : general considerations
Around 2008 synthetic cannabinoids were found to be present in and responsible for the psychoactive effects of herbal mixtures with names like ‘Spice’ or ‘K2’. In response to the increased popularity of these products, (inter)national organizations and governments started banning these cannabimimetics gradually. However, the lack of an uniform and international regulation makes it hard to control this issue.
For the different types of synthetic cannabinoids the scientific knowledge in terms of pharmacokinetics and pharmacodynamics is limited. This also means that little is known on the health of users, both on short and long term.
In the last years effort has been made to make detection of these products possible in different biological matrices. However, since the number of cannabimimetic compounds on the market appears to grow every month, both scientist and legislators run after a moving target
Are There Philosophical Answers to Psychiatric Questions?
Contemporary psychiatry has only one generally
accepted model, that of biological – materialist explanation
and treatment. But clinicians recognize that this model
omits much that is important and they therefore confront a
dilemma: either limit their practice to an incomplete model,
or use other models which seem unfounded and
speculative. Philosophical considerations may help
clinicians find a way out 1) by showing the inherent
limitations of biological – materialist explanations, and 2)
by grounding other (psychotherapeutic) approaches on
general considerations of how the mind, and in particular
language, works. These general considerations include:
the dependence of meaning upon environmental context,
the attribution of meaning as involving sets of skills,
capacities and reactions, the multiplicity of language
games and therefore their individual limitations, the
dependence of meaning upon our shared interests, the
largely unconscious nature of mind and our necessary
limitations to public criteria for mental events and
processes
THE RIGHT GENERAL CONSIDERATIONS
Aw is the normative and institutional order of human behavior in society inspired by postulates of justice, based on existing social relations that determine its content and character. In other words, they are behaviors directed to the observance of norms that regulate the social coexistence and allow to resolve intersubjective conflicts. The initial definition gives account of positive law, but not its foundation; jurists, philosophers and law theorists have proposed throughout history various alternative definitions and different legal theories without a consensus to date on their validity.Aw is the normative and institutional order of human behavior in society inspired by postulates of justice, based on existing social relations that determine its content and character.
