New Horizons in Psychiatry

Psychiatrists have long held that there should be more psychiatry in general medicine, and the nonpsychiatric physicians have said that there should be much more medicine in psychiatry. Both groups have been perfectly correct and are being told by the consuming population that there must be more sociology in each of them. The future psychiatrist must and will work with his colleagues in medicine, not to achieve a utopia, but at least to approach this desirable situation in some degree

Modeling phase transition and metastable phases

We propose a model that describes phase transition including metastable phases present in the van der Waals Equation of State (EoS). We introduce a dynamical system that is able to depict the mass transfer between two phases, for which equilibrium states are both metastable and stable states, including mixtures. The dynamical system is then used as a relaxation source term in a isothermal two-phase model. We use a Finite volume scheme (FV) that treats the convective part and the source term in a fractional step way. Numerical results illustrate the ability of the model to capture phase transition and metastable states

A relaxation model for liquid-vapor phase change with metastability

We propose a model that describes phase transition including meta\-stable states present in the van der Waals Equation of State. From a convex optimization problem on the Helmoltz free energy of a mixture, we deduce a dynamical system that is able to depict the mass transfer between two phases, for which equilibrium states are either metastable states, stable states or {a coexistent state}. The dynamical system is then used as a relaxation source term in an isothermal 4$\times$4 two-phase model. We use a Finite Volume scheme that treats the convective part and the source term in a fractional step way. Numerical results illustrate the ability of the model to capture phase transition and metastable states

Psycho-Social Aspects of Drug Abuse by Modern Youth

Research in human behavior rarely lends itself to the scientific rigors which allow for definitive cause and effect answers even if they exist. Perhaps no facet of human life has a simple origin, and certainly that is true of behavior which involves all levels of personality function and social interaction such as occurs in drug abuse. Drug abuse undoubtedly is overdetermined behavior with multiple etiological factors in a constantly fluxuating interaction. Most observers agree that drug abuse by the youth has become a major problem, but differences arise when the sociological and psychological factors of etiology are discussed. The many concepts of etiology are more or less products of the individual observer\u27s orientation and past experience, and therefore, they rarely are subject to cross validation

Psychiatric Problems in Urology

In summary, the urologist cannot escape from a major responsibility for his patients\u27 emotional components. The very area of his work is highly charged with emotional potential, primarily of a sexual nature. A careful sexual history is essential to the full understanding of the symptoms of many urological complaints and is equally necessary for the prevention of emotional complications to genital surgery

Psychological Abnormalities of Sexual Identification

The normal process of development of sexual identification slides almost unnoticed through well-defined, but overlapping stages to a definite end point. That end point is an individual who senses that his core gender, male or female, is consistent with the body morphology, the external genitalia, the chromosomal configuration, and the hormonal balance. Also, there must be the development of personality traits, masculine or feminine, consistent with the sense of core gender. Finally, although somewhat outside the scope of our present discussion, there must be the establishment of a role or life style in adulthood in accordance with the first two steps. The end point normally is sexual behavior acceptable to both the individual and to society, that is, heterosexual behavior in an individual who is comfortable with himself

Thermal Recovery of Multi-Limbed Robots with Electric Actuators

The problem of finding thermally minimizing configurations of a humanoid robot to recover its actuators from unsafe thermal states is addressed. A first-order, data-driven, effort based, thermal model of the robots actuators is devised, which is used to predict future thermal states. Given this predictive capability, a map between configurations and future temperatures is formulated to find what configurations, subject to valid contact constraints, can be taken now to minimize future thermal states. Effectively, this approach is a realization of a contact-constrained thermal inverse-kinematics (IK) process. Experimental validation of the proposed approach is performed on the NASA Valkyrie robot hardware

Qualified market access: an economic, empirical and legal analysis

In the aftermath of the debate on trade and “collective preferences” launched by Pascal Lamy in 2004, this paper considers a proposal for non-product related production process measures developed within the European Parliament, which involved surcharges on the imports of products produced in ways which do not satisfy the EU’s rules mainly but not exclusively for agricultural commodities and in particular on animal welfare. The proposal called “Qualified Market Access” would also have made the revenues from surcharges available to exporting countries to finance compliance. This paper discusses the philosophy behind this specific proposal to qualify market access and address consumer preferences and competitiveness concerns, as identified in a number of other actual and proposed measures, including the ban on seal fur imports into the EU and the ensuing challenge to this measure in the WTO Dispute Settlement Body. The paper contends that it cannot be ruled out that such a measure would be welfare improving if consumers have strong preferences regarding what other people consume, in which case labelling alone will not work and the case for such a proposal cannot be excluded a priori, even from a legal perspective. However, in reviewing the evidence, the paper concludes that there is no empirical evidence to support such a proposal

The imprint of photoevaporation on edge-on discs

We have performed hydrodynamic and radiative transfer calculations of a photoevaporating disc around a Herbig Ae/Be star to determine the evolution and observational impact of dust entrained in the wind. We find that the wind selectively entrains grains of different sizes at different radii resulting in a dust population that varies spatially and increases with height above the disc at radii > 10 AU. This variable grain population results in a 'wingnut' morphology to the dust density distribution. We calculate images of this dust distribution at NIR wavelengths that also show a wingnut morphology at all wavelengths considered. We have also considered the contribution that crystalline dust grains will have in the wind and show that a photoevaporative wind can result in a significant crystallinity fraction at all radii, when the disc is edge-on. However, when the disc's photosphere is unobscured, a photoevaporative wind makes no contribution to the observable crystallinity fraction in the disc. Finally, we conclude that the analysis of extended emission around edge-on discs could provide a new and independent method of testing photoevaporation models.Comment: 8 pages, 6 figures, accepted for publication in MNRA
