The impact of professional and economic activity on the development of apartments market
Purpose: The aim is to examine to what extent does the professional activity of the population and the economic activity of entrepreneurs affect the development of the apartments‘ market. The subject of the study are local real estate markets – the sector of commercial investments – residential seaside apartments. Design/Methodology/Approach: We analysed data about real estate markets of Polish communes located in Central Pomerania. The values of the analysed indicators were calculated using Excel program and the results were presented in the form of Tables and Figures in Microsoft Excel and ArcMap. Findings: The results show that there is a relationship between the professional activity of the population and the economic activity of entrepreneurs in the tourist communes and the development of the primary and secondary real estate markets. The analysis shows that economic effects of tourism development can influence the income of the commune, an increase in local revenue achieved by entities that manage tourism, high professional activity of the population and economic activity of entrepreneurs as well as the diversification of the economy thus allowing to obtain independence from the economic instability. Practical Implications: The most important practical implication is the statements that there is a need to make new investments in seaside towns in which the tourist market is developing. Originality/Value: The analysis shows that economic effects of tourism development can influence the income of the commune with an increase in the local revenue achieved by entities that manage tourism.peer-reviewe
Stochastically positive structures on Weyl algebras. The case of quasi-free states
We consider quasi-free stochastically positive ground and thermal states on
Weyl algebras in Euclidean time formulation. In particular, we obtain a new
derivation of a general form of thermal quasi-free state and give conditions
when such state is stochastically positive i.e. when it defines periodic
stochastic process with respect to Euclidean time, so called thermal process.
Then we show that thermal process completely determines modular structure
canonically associated with quasi-free state on Weyl algebra. We discuss a
variety of examples connected with free field theories on globally hyperbolic
stationary space-times and models of quantum statistical mechanics.Comment: 46 pages, amste
Burgers velocity fields and dynamical transport processes
We explore a connection of the forced Burgers equation with the
Schr\"{o}dinger (diffusive) interpolating dynamics in the presence of
deterministic external forces. This entails an exploration of the consistency
conditions that allow to interpret dispersion of passive contaminants in the
Burgers flow as a Markovian diffusion process. In general, the usage of a
continuity equation , where
stands for the Burgers field and is the
density of transported matter, is at variance with the explicit diffusion
scenario. Under these circumstances, we give a complete characterisation of the
diffusive matter transport that is governed by Burgers velocity fields. The
result extends both to the approximate description of the transport driven by
an incompressible fluid and to motions in an infinitely compressible medium.Comment: Latex fil
A "Garden of Forking Paths" - the Quantum Mechanics of Histories of Events
We present a short survey of a novel approach, called "ETH approach", to the
quantum theory of events happening in isolated physical systems and to the
effective time evolution of states of systems featuring events. In particular,
we attempt to present a clear explanation of what is meant by an "event" in
quantum mechanics and of the significance of this notion. We then outline a
theory of direct (projective) and indirect observations or recordings of
physical quantities and events. Some key ideas underlying our general theory
are illustrated by studying a simple quantum-mechanical model of a mesoscopic
system.Comment: 26 pages, 3 figure
