Models occupy a central role in the scientific endeavour. Among the many purposes they serve, representation is of great importance. Many models are representations of something else; they stand for, depict, or imitate a selected part of the external world (often referred to as target system, parent system, original, or prototype). Well-known examples include the model of the solar system, the billiard ball model of a gas, the Bohr model of the atom, the Gaussian-chain model of a polymer, the MIT (...) bag model of quark confinement, the Lorenz model of the atmosphere, the Lotka-Volterra model of the predator-prey interaction, or the hydraulic model of an economy, to mention just a few. All these models represent their target systems (or selected parts of them) in one way or another. (shrink)

GRW Theory postulates a stochastic mechanism assuring that every so often the wave function of a quantum system is `hit', which leaves it in a localised state. How are we to interpret the probabilities built into this mechanism? GRW theory is a firmly realist proposal and it is therefore clear that these probabilities are objective probabilities (i.e. chances). A discussion of the major theories of chance leads us to the conclusion that GRW probabilities can be understood only as either single (...) case propensities or Humean objective chances. Although single case propensities have some intuitive appeal in the context of GRW theory, on balance it seems that Humean objective chances are preferable on conceptual grounds because single case propensities suffer from various well know problems such as unlimited frequency tolerance and lack of a rationalisation of the principal principle.

Gibbsian statistical mechanics (GSM) is the most widely used version of statistical mechanics among working physicists. Yet a closer look at GSM reveals that it is unclear what the theory actually says and how it bears on experimental practice. The root cause of the difficulties is the status of the averaging principle, the proposition that what we observe in an experiment is the ensemble average of a phase function. We review different stances toward this principle, and eventually present a coherent (...) interpretation of GSM that provides an account of the status and scope of the principle. (shrink)

Consider a gas that is adiabatically isolated from its environment and confined to the left half of a container. Then remove the wall separating the two parts. The gas will immediately start spreading and soon be evenly distributed over the entire available space. The gas has approached equilibrium. Thermodynamics (TD) characterizes this process in terms of an increase of thermodynamic entropy, which attains its maximum value at equilibrium. The second law of thermodynamics captures the irreversibility of this process by positing (...) that in an isolated system such as the gas entropy cannot decrease. The aim of statistical mechanics (SM) is to explain the behavior of the gas and, in particular, its conformity with the second law in terms of the dynamical laws governing the individual molecules of which the gas is made up. In what follows these laws are assumed to be the ones of Hamiltonian classical mechanics. We should not, however, ask for an explanation of the second law literally construed. This law is a universal law and as such cannot be explained by a statistical theory. But this is not a problem because we.. (shrink)

It is argued, in this paper, that the core operation underlying any measurement—the inverse modelling under uncertainty—is equivalent to quantitative abductive reasoning which consists in the selection of the best estimate of a measurand in a set of admissible solutions, using a priori information: on the measurand, on the measuring system coupled with an object under measurement, and on the influence of the environment including the user of the measurement results. There are two key premises of this claim: a systematic (...) interpretation of measurement in terms of inverse problems, proposed earlier by the author, and a logical link between inverse problems and abduction, identified by the Finnish philosopher of science Ilkka Niiniluoto. The title claim of this paper is illustrated with an expanded example of measuring optical spectrum by means of a low-resolution spectrometer. (shrink)

While e-commerce has witnessed extensive growth in recent years, so has consumers' concerns regarding ethical issues surrounding online shopping. The vast majority of earlier research on this area is conceptual in nature, and limited in scope by focusing on consumers' privacy issues. This study develops a reliable and valid scale to measure consumers' perceptions regarding the ethics of online retailers. Findings indicate that the four factors of the scale - security, privacy, non-deception and fulfillment/reliability - are strongly predictive of online (...) consumers' satisfaction and trust. The results offer important implications for e-retailers and are likely to stimulate further research in the area of e-ethics from the consumers' perspective. (shrink)

The last decade and a half has seen an ardent development of self-organised criticality, a new approach to complex systems, which has become important in many domains of natural as well as social science, such as geology, biology, astronomy, and economics, to mention just a few. This has led many to adopt a generalist stance towards SOC, which is now repeatedly claimed to be a universal theory of complex behaviour. The aim of this paper is twofold. First, I provide a (...) brief and non-technical introduction to SOC. Second, I critically discuss the various bold claims that have been made in connection with it. Throughout, I will adopt a rather sober attitude and argue that some people have been too readily carried away by fancy contentions. My overall conclusion will be that none of these bold claims can be maintained. Nevertheless, stripped of exaggerated expectations and daring assertions, many SOC models are interesting vehicles for promising scientific research.Author Keywords: Self-organised criticality; Scaling law; Models; Formal analogy.

In the paper n -valued paraconsistent matrices are defined by an adaptation of the well-known Łukasiewicz’s matrices. An appropriate set of axioms is presented and the 3-valued case is examined.

The paper presents the life and work of Feliks Koneczny, the forgotten polish scientist of the 19th and the 20th centuries. The four main field of his activity areshortly presented, especially his historiosophic synthesis in form of very original theory of the plurality of civilizations, based on the axiological assumptions. His concept of social philosophy that emerged from his historical studies seems to be controversial but, in fact, has strongly influenced the work of many historians and philosophers. In his opinion, (...) any utilitarian political, economical, social and psychological functionality turned into the ideologically imposed life algorithms must be considered as very dangerous threat for the freedom and free will of individual as well as for the independence of so many different communities, societies and cultures. Consequently, Koneczny suggested to be very careful in attempts to implement, by international political means, the idea of total globalization considering it as harmful illusion. (shrink)

Purpose of the article: Most regional macroeconomic processes may not be adequately analyzed without accounting for their spatial nature: regional distances, interactions between neighbors, spill-over effects and interdependencies. This contribution focuses on various factors ruling unemployment dynamics in the Visegrad Group countries and their major economic partners: Germany and Austria. The analysis is performed at the NUTS2 level. Methodology/methods: Spatial econometrics is a unique tool for a broad range of quantitative analyses and evaluations. Spatial econometric models are based on geo-coded (...) data. Spatial econometrics and regional competitiveness paradigms are combined into different types of regression model specifications describing unemployment dynamics. Alternative spatial structures are used for verification of stability in estimated model properties. Scientific aim: We aim to provide a detailed empirical evaluation of spatially determined factors of regional unemployment dynamics, along with insight into the robustness of such approach. Both conceptually and parametrically varying neighbor definitions are used to provide evidence for model evaluation. Findings: We find strong positive spatial dependence patterns in the estimated models, robust against varying neighborhood definitions. Our results strongly support the importance of regional and potentially cross-border cooperation in macroeconomic policies addressing unemployment. The estimated models also underline the importance of using spatial models, by pointing out the bias in OLS-estimated models. Conclusions and limits: Spatial approach to econometric analysis provides important insight and robustness to a broad range of unemployment analyses that may be carried out using regional data. At the same time, it should be noted that this article focuses mostly on the spatial and stability aspects of model estimation, while leaving out other interesting topics such as spill-over effects calculations as based on estimated models. Also, estimations provided in this article might benefit from spatial panel data-based methods - once data availability issues are sorted. (shrink)

Ces dernieres annees, plusieurs travaux sur la philosophie des jesuites en Pologne au XVIᵉ XVIᵉ et XVIIᵉ siecle ont ete publies. Ceux qui sent ecrits en langues plus connues, sont enumeres dans la bibliographie a la fin de cet article. Malgre cela, on ne pent pas dire que cette philosophie soit suffisamment explicite. Mais actuellement, il existe deja des fondements plus solides pour essayer de creer une synthese de cette philosophie. Cet essai est d'autant plus fonde que d'apres l'opinion de (...) quelques historiens une synthese doit etre faite a chaque etape des recherches. Le present essai de synthese traite de la philosophie enseignee du XVIᵉ au XVIIIᵉ slecle dans les colleges des jesuites en Pologne et en Lituanie qui constituaient alors un seul etat — une Republique des deux Nations. II se rapporte donc au territoire de cet etat dans ses frontieres historiques. L'article comprend la periode de I'arrivee des jesuites en Pologne en 1564 jusqu'a la suppression de leur ordre en 1773.

Le maintien des relations parent-enfant en prison représente un véritable défi au regard des différentes formes d’empêchement – véritable mise en suspens de la parentalité – auxquels se trouvent confrontés les parents détenus et les enfants ainsi que leurs accompagnants. Membre d’une recherche inter-disciplinaire (droit et psychologie), menée en France dans trois établissements pénitentiaires en appui sur des questionnaires et la conduite de focus-groups, l’auteur met en évidence, au travers d’une approche clinique psychodynamique, la tension qui s’exerce entre les attentes (...) exprimées par les parents détenus à l’égard de leurs enfants et la disqualification dont leur lien est l’objet, en raison du vécu des conditions de détention et d’accueil des enfants ainsi que de l’accès à la prison des personnes qui, de l’extérieur, sont en mesure de soutenir les relations parent-enfant (conjoint ou ex-conjoint, famille...).
