The Existence of Pair Potential Corresponding to Specified Density and Pair Correlation

Given a potential of pair interaction and a value of activity, one can consider the Gibbs distribution in a finite domain $\Lambda \subset \mathbb{Z}^d$. It is well known that for small values of activity there exist the infinite volume ($\Lambda \to \mathbb{Z}^d$) limiting Gibbs distribution and the infinite volume correlation functions. In this paper we consider the converse problem - we show that given $\rho_1$ and $\rho_2(x)$, where $\rho_1$ is a constant and $\rho_2(x)$ is a function on $\mathbb{Z}^d$, which are sufficiently small, there exist a pair potential and a value of activity, for which $\rho_1$ is the density and $\rho_2(x)$ is the pair correlation function

Binary jumps in continuum. II. Non-equilibrium process and a Vlasov-type scaling limit

Let $\Gamma$ denote the space of all locally finite subsets (configurations) in $\mathbb R^d$. A stochastic dynamics of binary jumps in continuum is a Markov process on $\Gamma$ in which pairs of particles simultaneously hop over $\mathbb R^d$. We discuss a non-equilibrium dynamics of binary jumps. We prove the existence of an evolution of correlation functions on a finite time interval. We also show that a Vlasov-type mesoscopic scaling for such a dynamics leads to a generalized Boltzmann non-linear equation for the particle density

Internationalization in Higher Education: an Analysis of Croatian Universities

Around the globe, non-anglophone universities and higher education institutions (HEIs) are trying to internationalize providing students with opportunities to take non-language courses in a foreign language. The usual medium of instruction is English (EMI), which has become a global phenomenon. This paper aims to examine a macro-level university and HEIs’ policy on implementing non-language courses in four largest and oldest Croatian universities and their constituent units. Examining public records of the universities and HEIs, this study will research types and levels of study programs, operationalization of language medium instruction, policy implementation and curriculum evaluation. Since English/Language for Specific Purposes (ESP/LSP) courses can be perceived as preparatory courses for EMI/LMI, types, (non)obligatory nature and workload of ESP/LSP courses taught at the examined HEIs will be studied. The research showed that ESP courses are mostly taught as obligatory courses at the undergraduate level and occasionally as optional courses at the graduate study level. The highest workload of LSP courses is recorded at the HEIs from the Social Sciences fields and the lowest from the Natural Sciences fields, which consequently results in those HEIs (not) offering study programs in a foreign language

Tagged particle process in continuum with singular interactions

By using Dirichlet form techniques we construct the dynamics of a tagged particle in an infinite particle environment of interacting particles for a large class of interaction potentials. In particular, we can treat interaction potentials having a singularity at the origin, non-trivial negative part and infinite range, as e.g., the Lennard-Jones potential.Comment: 27 pages, proof for conservativity added, tightened presentatio

Mapping Mutual Fund Investor Characteristics and Modeling Switching Behavior

Securing a mutual fund that meets investment goals is an important reason why some investors exclusively stay with a particular mutual fund and others switch funds within their fund family. This paper empirically investigates investor attitudes toward mutual funds. Our model, based on investor responses, develops an investor\u27s risk profile variable. Results indicate that regardless of whether the investors invest in nonemployer plans or in both employer and nonemployer plans, they consider their investment risk, fund performance, investment mix, and the capital base of the fund before switching funds. The model developed in this study can also assist in predicting investors\u27 switching behavior
