Opis:
The paper deals with application of CPTu test results for the probabilistic modeling of dumping grounds. The statistical measures use results from 42 CPT test points located in the lignite mine dumping ground from the region of Central Europe. Both the tip resistance qc as well as local friction fs are tested. Based on the mean values and standard deviations of measured quantities the specific zones in the dumping site profile are distinguished. For three main zones standard deviations of linearly de-trended functions, distributions of normalized de-trended values for qc and fs are examined. Also the vertical scales of fluctuation for both measured quantities are estimated. The obtained result shows that lignite mine dumping site can be successfully described with the Random Field Theory. Additional use of fs values introduces supplementary statistical information.

Opis:
A black-hole is an astronomical entity which possesses infinite density at its gravitational singularity or singular point. The capacity of a black-hole to completely rip-off an entire solar system without leaving any evidence is to be noted. A debate has been going on over the past few decades regarding the information storage in black-holes. The discovery of Hawking radiation, which predicts complete evaporation of mass violates unitarity ie. Conservation of probability and energy fails. Recent discoveries suggest that regular remnant of black-hole survives evaporation , as a result information of the object devoured can be contained. These remnants are grouped into embedded sub-manifolds. These manifolds are the result of a five-dimensional constant curvature bulk in space-time. Five-dimensional gravity can be recovered from brane-world resulting from equations of bulk geometry. Gravity can be explained by space-time theory and also quantum theory in the form of Gravitons. On observing the manifold, the gravitons show deformations in dimensions, rather than being constant. The perturbations in geometry can be related to embedding functions which should remain differentiable and regular. Regularity is related to the inverse functions theorem. Manifold observations followed by a mathematical approach can possibly retain information about objects devoured by the black-hole.

Opis:
This article presents a formalized field theory of international migration. Departing from the theories of Kurt Lewin, the author assumes that the valences of different migration targets create a field of attracting forces, which may trigger long-range “locomotions.” Moreover, the author hypothesizes that the selection among the different migration targets also depends on the perceived opportunities: the higher the number of vacancies at a target and the stronger the reporting about these vacancies by earlier migrants, the stronger the field of perceived opportunities. A mathematical model based on these theoretical assumptions is tested with data about migration from Poland to other EU countries. The goodness of fit of the model is quite high and seems to corroborate its field theoretical foundations. The model is further explored by simulating its behavior for different scenarios of valences and perceived opportunities. The article finishes with a summary from the perspective of analytical sociology.

Opis:
In quantum field theory it is believed that the spontaneous decay of excited atomic or molecular level is due to the interaction with continuum of field modes. Besides, the atom makes a transition from upper level to lower one so that the probability to find the atom in the excited state tends to zero. In this paper it will be shown that the mathematical model in single-photon approximation may predict another behavior of this probability generally. Namely, the probability to find the atom in the excited state may tend to a nonzero constant so that the atom is not in the pure state finally. This effect is due to that the spectrum of the complete Hamiltonian is not purely absolutely continuous and has a discrete level outside the continuous part. Namely, we state that in the corresponding invariant subspace, determining the time evolution, the spectrum of the complete Hamiltonian when the field is considered in three dimensions may be not purely absolutely continuous and may have an eigenvalue. The appearance of eigenvalue has a threshold character. If the field is considered in two dimensions the spectrum always has an eigenvalue and the decay is absent.

Opis:
The purpose of the paper is take a look from the perspective of the field theory of Pierre Bourdieu at the history of the Polish post-war philosophy with special attention given to the so-called Christian philosophy. In reference to Bourdieu’s research practice, the author postulates application of research strategies of the sociology of science/philosophy to historical and philosophical studies with a belief that they enhance the picture of philosophical dynamics of the past. From this point of view, the author focuses on relations between the field of Christian philosophy and the field of church authority, exposing the issue of philosophy’s autonomy.

Opis:
The paper deals with evaluation of bearing capacity of strip foundation on random purely cohesive soil. The approach proposed combines random field theory in the form of random layers with classical limit analysis and Monte Carlo simulation. For given realization of random the bearing capacity of strip footing is evaluated by employing the kinematic approach of yield design theory. The results in the form of histograms for both bearing capacity of footing as well as optimal depth of failure mechanism are obtained for different thickness of random layers. For zero and infinite thickness of random layer the values of depth of failure mechanism as well as bearing capacity assessment are derived in a closed form. Finally based on a sequence of Monte Carlo simulations the bearing capacity of strip footing corresponding to a certain probability of failure is estimated. While the mean value of the foundation bearing capacity increases with the thickness of the random layers, the ultimate load corresponding to a certain probability of failure appears to be a decreasing function of random layers thickness.

Opis:
In contemporary media and communication science, mediatization is regarded as an “emerging paradigm”, but the term itself is diffuse and highly contingent. An attempt is made in this paper to integrate structural and individual concepts of mediatization theory by combining it with Bourdieu’s field theory using the example of science. After outlining the notion of mediatization underlying this text, the special features of scientific communication and the scientific field are presented. Hypotheses mentioned in the literature on the influence of new media technologies on science are contrasted with the state of research. This reveals that the impact of media innovations cannot be seen in a monocausal manner. In field-specific mediatization, they interact with various structural and individual elements.

Opis:
In the article, the author presents his own interpretation of Pierre Bourdieu’s concept of social field research. At the beginning, he introduces the general field theory and then presents the counselling practice as a manifestation of the counselling field operation. Subsequently, he presents methodological aspects of the field’s effects examination, makes the conceptualization of the main analytical categories and at the same time observable social phenomena, in particular doxa, illusio, generative structures of field’s divisions and classifications or counseling game stakes. In summary, he draws attention to the potential and limitations of field theory.
W artykule autor prezentuje własną interpretację koncepcji Pierre’a Bourdieu badania pola społecznego. Na początku przybliża ogólną teorię pola, a następnie przedstawia praktykę poradnictwa jako przejaw działania pola poradniczego. W dalszej kolejności prezentuje metodologiczne aspekty badania efektów tego pola, a więc dokonuje konceptualizacji głównych kategorii analitycznych, czyli jednocześnie takich obserwowalnych fenomenów społecznych, jak doxa, illusio, generatywne zasady klasyfikacji i podziałów pola czy stawki gry poradniczej. Podsumowując, zwraca uwagę na potencjał i ograniczenia teorii pola.

Opis:
Phenomenological concepts describing electromagnetic interactions were expressed mathematically by Maxwell in his theory of electromagnetic field. His work was not free of mechanistic influences. It also broke down some elements of inductionistic paradigme. Maxwell's theory cannot be reduced to a simple methodology of solving equations. Physical theories imply a deeper understanding of equations which carry an 'immaterial content'. The 'higher symmetries' hidden in the equations should to use Einstein's expressions be viewed as a 'stuff of the Universe'.

Opis:
Field theory is one of the most efficient and influential analytical schemes in the critical sociology of Pierre Bourdieu, which he consistently developed in his model of literary field. The analytical reliability of the model derives from the way in which Bourdieu combines the structural category of “field” with the phenomenological categories of “doxa” and “habitus”. This article argues that Bourdieu’s selective application of the two phenomenological categories produces a static structural model of literary field where all processes are explained in causal and deterministic terms. The article further seeks to present an alternative reading of the same categories within a discursive model where the processes in literary field and the motivations of its agents are driven by field’s discourses rather than by its rigid structures.
