Controllability on the group of diffeomorphisms
Given a compact manifold M, we prove that any bracket generating family of vector fields on M, which is invariant under multiplication by smooth functions, generates the connected component of the identity of the group of dieomorphisms

The power to resist: the relationship between power, stigma, and negative symptoms in schizophrenia.
Stigmatizing beliefs about mental illness can be a daily struggle for people with schizophrenia. While investigations into the impact of internalizing stigma on negative symptoms have yielded mixed results, resistance to stigmatizing beliefs has received little attention. In this study, we examined the linkage between internalized stigma, stigma resistance, negative symptoms, and social power, or perceived ability to influence others during social interactions among people with schizophrenia. Further, we sought to determine whether resistance to stigma would be bolstered by social power, with greater power in relationships with other possibly buffering against motivation/pleasure negative symptoms. Fifty-one people with schizophrenia or schizoaffective disorder completed measures of social power, internalized stigma, and stigma resistance. Negative symptoms were assessed using the Clinical Assessment Interview for Negative Symptoms (CAINS). Greater social power was associated with less internalized stigma and negative symptoms as well as more stigma resistance. Further, the relationship between social power and negative symptoms was partially mediated by stigma resistance. These findings provide evidence for the role of stigma resistance as a viable target for psychosocial interventions aimed at improving motivation and social power in people with schizophrenia
Interpretations of Quantum Mechanics: a critical survey
This brief survey analyzes the epistemological implications about the role of
observer in the interpretations of Quantum Mechanics. As we know, the goal of
most interpretations of quantum mechanics is to avoid the apparent intrusion of
the observer into the measurement process. In the same time, there are implicit
and hidden assumptions about his role. In fact, most interpretations taking as
ontic level one of these fundamental concepts as information, physical law and
matter bring us to new problematical questions. We think, that no
interpretation of the quantum theory can avoid this intrusion until we do not
clarify the nature of observer.Comment: LateX 17 pages, 4 figure

Psychosocial treatments for negative symptoms in schizophrenia: current practices and future directions.
Schizophrenia can be a chronic and debilitating psychiatric disorder. Though advancements have been made in the psychosocial treatment of some symptoms of schizophrenia, people with schizophrenia often continue to experience some level of symptoms, particularly negative symptoms, throughout their lives. Because negative symptoms are associated with poor functioning and quality of life, the treatment of negative symptoms is a high priority for intervention development. However, current psychosocial treatments primarily focus on the reduction of positive symptoms with comparatively few studies investigating the efficacy of psychosocial treatments for negative symptoms. In this article, we review and evaluate the existing literature on three categories of psychosocial treatments--cognitive behavioral therapy (CBT), social skills training (SST), and combined treatment interventions--and their impact on the negative symptoms of schizophrenia. Of the interventions reviewed, CBT and SST appear to have the most empirical support, with some evidence suggesting that CBT is associated with maintenance of negative symptom improvement beyond six months after treatment. It remains unclear if a combined treatment approach provides improvements above and beyond those associated with each individual treatment modality. Although psychosocial treatments show promise for the treatment of negative symptoms, there are many unanswered questions about how best to intervene. We conclude with a general discussion of these unanswered questions, future directions and methodological considerations, and suggestions for the further development of negative symptom interventions
Controllability on infinite-dimensional manifolds
Following the unified approach of A. Kriegl and P.W. Michor (1997) for a
treatment of global analysis on a class of locally convex spaces known as
convenient, we give a generalization of Rashevsky-Chow's theorem for control
systems in regular connected manifolds modelled on convenient
(infinite-dimensional) locally convex spaces which are not necessarily
normable.Comment: 19 pages, 1 figur
A probabilistic approach to quantum mechanics based on tomograms
It is usually believed that a picture of Quantum Mechanics in terms of true
probabilities cannot be given due to the uncertainty relations. Here we discuss
a tomographic approach to quantum states that leads to a probability
representation of quantum states. This can be regarded as a classical-like
formulation of quantum mechanics which avoids the counterintuitive concepts of
wave function and density operator. The relevant concepts of quantum mechanics
are then reconsidered and the epistemological implications of such approach
discussed
