Opis:
The aim of the study is to evaluate the concept of culture in the face of social heterogeneity. Focusing on the distinction between homogeneity and heterogeneity on the example of musical culture the author focuses on four questions. Does the concept of culture in its theoretical formulation mean that it necessarily crosses the border of the formal set-theory ontology and leads to the multiplying of the entities? Are there acceptable criteria for differentiating the cultural aspect of human affairs from other aspects? Can the practice of distinguishing the less or more unified wholes called cultures be justified when confronted with the irreducible complexity and heterogeneity of social life? Is the concept of culture, though useful for the analysis of non European and past European societies, still operative for the analysis of contemporary societies?

Opis:
Aim: Money velocity data for the United States show that there is a decline in all of the broad money aggregates in recent decades. This points to a sustained demand deficiency element. Can consumer heterogeneity be the cause of this declining trend? The aim of this paper is to find an answer for this question.   Design / Research Methods: To achieve our aim we use Agent Based Modelling (ABM). In our model, the agents are heterogeneous consumers with different spending propensities.   Conclusions / findings: We show that heterogeneous consumers with different spending propensities alone puts a downward pressure on money velocity. This pressure is coupled with a sustained worsening in the wealth distribution. We observe that as money accumulates in the hands of agents with the lowest propensity to spend, money velocity keeps declining. This also puts a downward pressure on nominal aggregate demand and hence a deflationary bias on the general price level.   Originality / value of the article: This paper shows that heterogeneity of economic agents should not be ignored and that ABM is a very powerful tool to analyse heterogeneity.   Implications of the research: The implication for policy makers is that the demand deficiency associated with the fall in money velocity will persist until the worsening of wealth dispersion comes to a halt.

Opis:
Student heterogeneity in (foreign language) instruction is a problem and a major professional challenge in both theory and practice. This problem/ challenge will be discussed in the contribution as a paradox of pedagogical and didactic work from its beginnings onwards. This is followed by a reflection on the institutional and structural frameworks for differentiation as a conceptual option for appropriate treatment of student heterogeneity. The empirical part, stimulated by the students’ statements during a didactics seminar, presents the results of a qualitative analysis of statements by foreign language teachers about differentiation, possibilities of differentiation, dilemmas, and pitfalls. Finally, suggestions are presented through which differentiation could find its way from theory to practice.

Opis:
Heterogeneity of granular materials triggers shear zone formation. In the paper, the FE-analysis of the effect of the material heterogeneity on the formation of a spontaneous shear zone inside of granular materials during a plane strain compression test is presented. The numerical calculations are performed with a finite element method on the basis of a hypoplastic constitutive law extended by polar quantities: rotations, curvatures and couple stresses. A mean grain diameter is used as a characteristic length. The constitutive law takes into account the effect of pressure, void ratio, direction of deformation rate and mean grain diameter on the behaviour of granular bodies. The heterogeneity in the granular body is assumed in the form of spots with a different initial void ratio. The spots are single or distributed randomly and stochastically with an exponential probability function. The single spots are distributed sparsely and densely in an initially dense and loose granular specimen. Special attention is focused on the effect of heterogeneity on the onset of shear localization and its thickness at residual state.

Opis:
This study aims at identifying determinants of health related quality of life in Poland, and in particular at verifying whether health domains are complements or substitutes and what the impact of heterogeneity of population on the health state valuation is. The paper uses data in panel structure coming from a survey conducted in Poland and consisting of 6700 valuations (after data cleaning) of EQ-5D health states with time trade-off method. Several econometric models are built in order to detect the impact of complementarity and heterogeneity. Random effects models as well as random parameters models estimated using Bayesian approach are used. The results show that health domains are complementary goods. Especially the lack of pain/discomfort is a complement to other health domains. Demographic factors influence how health state change impacts utility. These factors encompass sex, education, respondent's health state and even belief in life after death.

Opis:
This article concerns the assessment of selected physical and mechanical properties of a dump soil. The dump soil is a specific soil with a very heterogeneous internal structure. Next to each other, there may be lumps and crumbs of cohesive soils mixed with non-cohesive soils accompanied by a very diverse admixture of organic substance. In addition, the soil in the waste dump, in spatial terms, may significantly differ in consistency and density. This is the result of the process of forming a dump soil, which takes place in three stages: excavation, transport and dumping. A heterogeneous soil deposited within the waste dump is subject to further processes: consolidation, compaction and creeping. Changes occurring in the course of these processes have a significant impact on the development of the properties of the dump soil. Due to the large diversity of the tested soils, the results of their properties were divided into two groups, based on type and consistency of soil. This allows us to estimate the selected properties of the dump soil only on the basis of their macroscopic analysis.

Opis:
Earthquakes yield motions of massive rock layers accompanied by vibrations which travel in waves. This paper analyses the possibility of G-type wave propagation along the plane surface at the interface of two different media which is assumed to be heterogeneous and viscoelastic. The upper layer is considered to be viscoelastic and the lower half space is considered to be an initially stressed heterogeneous half space. The dispersion equation, as well as the phase and group velocities, is obtained in closed form. The dispersion equation agrees with the classical Love type wave. The effects of the nonhomogeneity of the parameters and the initial stress on the phase and group velocities are expressed by means of a graph.

Opis:
This study investigates the geographical dimension of tourist accommodation in Slovenia, Croatia, and Bosnia and Herzegovina and attempts to synthesize its spatial structure. The countries were chosen for the study due to their undoubted tourism qualities, their proximity in terms of location and, at the same time, the fundamental diversity of country size, population and access to the sea. The basis of this research was the use of point of interest (POIs), an open-source data, to analyse the spatial heterogeneity of the different types of accommodation. Kernel Density Estimation and Empirical Bayesian Kriging were used in the research.

Opis:
There are reasons researchers may be interested in accounting for spatial heterogeneity of preferences, including avoiding model misspecification and the resulting bias, and deriving spatial maps of willingness-to-pay (WTP), which are relevant for policy-making and environmental management. We employ a Monte Carlo simulation of three econometric approaches to account for spatial preference heterogeneity in discrete choice models. The first is based on the analysis of individual-specific estimates of the mixed logit model. The second extends this model to explicitly account for spatial autocorrelation of random parameters, instead of simply conditioning individual-specific estimates on population-level distributions and individuals’ choices. The third is the geographically weighted multinomial logit model, which incorporates spatial dimensions using geographical weights to estimate location-specific choice models. We analyze the performance of these methods in recovering population-, region- and individual-level preference parameter estimates and implied WTP in the case of spatial preference heterogeneity. We find that, although ignoring spatial preference heterogeneity did not significantly bias population-level results of the simple mixed logit model, neither individual-specific estimates nor the geographically weighted multinomial logit model was able to reliably recover the true region- and individual-specific parameters. We show that the spatial mixed logit proposed in this study is promising and outline possibilities for future development.

W pracy rozważa się problem testowalności dwóch hipotez związanych z estymacją względnej mocy dwóch preparatów stosowanych we wspólnym układzie z dwukierunkową eliminacją niejednorodności jednostek eksperymentalnych. Dla takiego układu przedstawia się model liniowy wielowymiarowych obserwacji, hipotezy związane z estymacją względnej mocy preparatów oraz funkcje testowe do weryfikacji hipotez zerowych. Dowodzi się, że obydwie hipotezy dla rozważanego układu doświadczalnego są testowalne.
Estimation of the constant potency of a test preparation relative to a standard preparation in multivariate parallel-line assays is discussed. The case when doses of both preparations are administered to experimental units forming a two-way elimination of heterogeneity design is considered. For such a design, a multivariate linear model of observations is described and test functions for the hypotheses about parallelism and relative potency of the preparations are presented.
