Measurement in Quantum Physics

The conceptual problems in quantum mechanics -- related to the collapse of the wave function, the particle-wave duality, the meaning of measurement -- arise from the need to ascribe particle character to the wave function. As will be shown, all these problems dissolve when working instead with quantum fields, which have both wave and particle character. Otherwise the predictions of quantum physics, including Bell's inequalities, coincide with those of the standard treatments. The transfer of the results of the quantum measurement to the classical realm is also discussed.Comment: 34 pages, in Latex, revised and expanded version with an extra appendix on decoherenc

Suppression of negative affect in cancer patients. Trauma and defensiveness of self-esteem as predictors of depression and anxiety

The results of the work show that the relatively small differences in declared, negative emotional states (such as depression or anxiety) between people suffering and not suffering from cancer can be explained by the suppression of negative affect in the former. It was assumed that the suppression is related to a compensation of an automatic, affective self-assessment - i.e. implicit self-esteem, lower in cancer patients. The results confirmed that the connection of cancer and depression (similarly cancer and anxiety) became significantly stronger while the self-esteem defensiveness and past stress are statistically controlled
