Purpose: The aim of the paper is to verify the process of в-convergence at a local level in Poland within 2007-2016, taking the impact of spatial effects and obtained EU funds related to innovation on economic growth into account. Design/methodology/approach: Spatial econometric methods were used in the research procedure. The modelling uses the economic aggregate, which is an alternative to the GDP measure of development. In addition, the traditional convergence equations were modified by adding variables defining spatial interactions to the specifications of the estimated models that may affect the rate of economic growth. The study covers data from all counties (NTS4) in Poland. Findings: The estimated econometric models showed that between 2007-2016, there was a slow process of reducing economic inequalities between counties in Poland. The convergence process was conditioned by the amount of European funds obtained for innovation. The funds acquired in a given county stimulated the economic growth of this unit while, at the same time, having negative impact on the development dynamics of neighbouring units. Originality/value: The added value of this elaboration is the inclusion of spatial effects affecting economic growth in the conducted analyses of conditional convergence. The presented study is one of a few in which the spatial impact was verified by including weights in the modelling of the matrix based on proximity, distance, flows and affiliation, carried out using data relating to all NTS4 units of a given European Union country.

The main objective of this paper is to compare the effects of the occurrence of public goods versus local government expenditures on the development of touristic facilities in rural areas. The specific objective focuses on identifying patterns of spatial dependence and analysing the distance bands in which spatial effects occur, especially accounting for backwash effects. The analysis provides insight into the spillovers that are usually omitted while building spatial development plans. The robust-VCE Poisson Spatial Durbin Model based on data from the entire population of counties in Poland was used. We found that local policies, spending, and spatial planning can compensate for a lower endowment of public goods. The negative spatial effect of the occurrence of public goods generally exceeded the positive effect of clustering.

Głównym celem artykułu jest ocena znaczenia dóbr publicznych na obszarach wiejskich dla rozwoju bazy turystycznej w kontekście wysokości wydatków samorządu terytorialnego związanych z rozwojem turystyki. Cel szczegółowy koncentruje się na identyfikacji wzorców zależności przestrzennych i analizie zakresu, w którym występują efekty przestrzenne, ze szczególnym uwzględnieniem negatywnej korelacji przestrzennej, tj. efektu „wypłukiwania” zasobów (tzw. „backwash effect”). Analiza daje szczegółowy wgląd w autokorelacje przestrzenne, które są zazwyczaj pomijane przy konstruowaniu miejscowych planów zagospodarowania przestrzennego. Posłużono się odpornym modelem Durbina (SDM) dla rozkładu Poissona estymowanym na próbie wszystkich powiatów w Polsce. Ustalono, że lokalna polityka gospodarcza, wydatki samorządowe i odpowiednie planowanie przestrzenne mogą zrekompensować mniejszą zasobność powiatu w dobra publiczne. Negatywny efekt przestrzenny występowania dóbr publicznych na ogół przewyższał jednak pozytywny efekt tworzenia klastrów turystycznych.

As the virtual reality (VR) market is growing at a fast pace, numerous users and producers are emerging with the hope to navigate VR towards mainstream adoption. Although most solutions focus on providing high- resolution and high-quality videos, the acoustics in VR is as important as visual cues for maintaining consistency with the natural world. We therefore investigate one of the most important audio solutions for VR applications: ambisonics. Several VR producers such as Google, HTC, and Facebook support the ambisonic audio format. Binaural ambisonics builds a virtual loudspeaker array over a VR headset, providing immersive sound. The configuration of the virtual loudspeaker influences the listening perception, as has been widely discussed in the literature. However, few studies have investigated the influence of the orientation of the virtual loudspeaker array. That is, the same loudspeaker arrays with different orientations can produce different spatial effects. This paper introduces a VR audio technique with optimal design and proposes a dual-mode audio solution. Both an objective measurement and a subjective listening test show that the proposed solution effectively enhances spatial audio quality.

Often, most cities grow as a result of the increase in population in addition to increased urbanization in developing cities, including in Iraq. Where urban growth is defined as a set of phenomena, which offers geographical, economic, social and administrative advantages in terms of attraction and influence, the areas associated with them tend to suffer from population concentration and accumulation in productive activities and services. This results in social impacts on an economic, geographical and administrative scale in the region itself and its surroundings [4]. Usually, growth sites in the city are places where development is feasible with the lowest possible costs on flat land and close to infrastructure services, especially transport corridors.
