Abstract

An effective knowledge-based economy requires regular cooperation between science and business. This is possible thanks to enterprises that create and implement innovations The paper focuses on the recognition of R&D expenditure. This aims to verify if firms with a scientist on their board are more likely to invest in the R&D. We conduct a tobit panel analysis of over 18,000 Polish private firms combined with data on patents and scientists employed at universities. The findings show that firms with scientists on the supervisory board are likely to invest more in R&D. However, these investment in R&D of firms with a scientist on the board are financial constraint. Their growth depends on access to finance. Therefore, institutions in Poland should support and promote cooperation between science and business, aiming for the realization of the implementation research. This approach requires updated regulations in the accounting area relating to the recognition of R&D inputs and outcomes.

Summary

Subject and purpose of work: The article presents the results of research into the dynamics of changes in income distribution as measured by means of GDP per capita for the regions Bulgaria and Slovakia using quantitative methods.

Materials and methods: The transition matrix was used as a research tool. As some authors note, since most of the research is limited to the assessment and analysis of global trends, this does not allow to distinguish the situation in which regions maintain their relative position from the situations in which the general distribution of income changes slightly while the location of some regions changes significantly. In this case, individual regions may differ considerably in their rate of development even in the periods when no convergence was observed.

Results: The approach adopted in this study made it possible to verify the degree of diversification of the economic strength of the regions examined and conduct a comparative analysis of the dynamics of changes in the transition matrices.

Conclusions: It was concluded that the regions of Slovakia and Bulgaria are developing at the same pace. Income stability can be observed. It is justifiable to look for and workout modern tools that will enable tracking changes in regional development.

Abstract

The propagation of waves generated by load impulse of two FWD types was assessed using test outputs in the form of time history data. The calculated travel time of wave between the receiver in the centre of load and others receivers showed the contradiction with the theory as for the receivers up to 600 (900) mm from the centre of load. Therefore, data collected by the sensors positioned at the distance of 1200 and 1500 mm were used.

The influence of load magnitude on the waves propagation was investigated via the different load force with approximately the same load time and vice versa. Expectations relating to the travel time of waves, depending on the differences of load impulse, were not met. The shorter travel time of waves was detected in the case of the lower frequencies. The use of load impulse magnitude as a possible explanation was not successful because opposite tendencies in travel time were noticed.

Abstract

The complexity of multi-component real properties results from the possibility of identifying various components in legal, physical or functional terms. The possibility of distinguishing various functional elements of real properties, combined with the specificity resulting from their market properties, is problematic when applying the comparative approach to real estate valuation. In this case, the valuation procedure can be implemented using statistical models: the parametric model or the conditional one.

This research paper demonstrates the construction of the parametric and conditional models taking into account the geometric and pricing attributes of multi-component real estate. The authors paid attention to adjusting the models to the available market data. They also specified the conditions for the use of statistical models in the real estate valuation process. Based on the analytical and accounting considerations, the estimation criteria for the parametric model and the conditional model were defined, which allow the correct application of these models at the stages of the real estate market analysis and the real estate valuation process.

Abstract

Average prices of residential real estate usually show significant variation on a regional basis. This reflects different social, economic or historical conditions for the development of these markets. In addition, research so far has not provided strong evidence supporting convergence in the level of property prices in the regional dimension. The lack of price convergence, however, does not exclude convergence in the direction and strength of price changes.

The article is an attempt to answer the question of whether price trajectories in the regional housing markets in Poland show long-term similarity. To this end, econometric analysis of the dynamics of relative prices in the voivodship markets with the use of quarterly data from the years 2002-2016 has been conducted.

Abstract

Every year, many people in the world lose their homes due to natural disasters such as earthquakes, floods and so on. In critical situations, the use of prefabricated parts in the buildings has many technical and economic advantages. Hence, today, this technology is widely used in the industrialized societies. The purpose of this research is to provide an appropriate model for speeding up the process of constructing buildings using prefabricated parts in critical conditions. To do this, Analytic Network Process (ANP) approach has been used to select the best option for speeding up construction projects using prefabricated parts and in critical situations. In this study, the intended criteria are quality, time, cost, and strength. The options that we should compare and the best option among them, according to the criteria mentioned, are Lightweight Steel Frame (LSF) parts, steel parts and concrete parts. In order to find this prioritization, the viewpoints of civil engineers and construction experts have been used. It should also be noted that for the ANP method, the Super Decisions software has been used.

Abstract

It is believed that the ad valorem tax will increase fiscal burdens. In order to verify this statement, with the use of the Szczecin Algorithm of Real Estates Mass Appraisal, the land plots were appraised and the ad valorem tax was calculated. Next, a training set was sampled, for which the composite variable was calculated by means of three approaches: the TOPSIS method, the Generalised Distance Measure as the composite measure of development (GDM2), and the quasi-TOPSIS. They were the explanatory variables in the logistic regression model. Next, for the test set, changes of tax burden were forecasted. The aim of the research was to check the effectiveness of the presented approach for the estimation of the consequences of introducing the ad valorem tax. The results showed that all three approaches yielded similar results, but GDM2 was the best one. The main finding is that these approaches can be used in the prediction of changes in the tax burden of land plots.

Abstract

Based on the previously published researches of the phenomenon of populism and its presence in the Republic of Croatia, and using methodological contents analyis matrix, which has been developed by B. Šalaj and M. Grbeša Zenzerović, this paper deals with the research of the presence of populism in the early Parliamentary election held in 2016. The researches of the phenomenon of populism have been intensified on both local and global level, and populism, as a concept, is becoming increasingly present in social and political discourse. However, everyone and everything is then easily classified as populistic. In the context of the Republic of Croatia, which has been through numerous state orders throughout its political history, this paper is going to examine if there was populism, as an aspect of political action, in the 2016 elections, and it is going to potentially identify the political actors, who have been using populistic features in their political careers. Furthermore, it is going to examine which kind of populism it is.

Abstract

Trends in marketing are changing and adopting new technologies, but what always remains is good content and relevant data. New knowledge, information and use of new tools are often crucial for the success of a company. Modern business in the domain of personal marketing can no longer be efficiently implemented without the use of new e-technologies. The application of Internet technology implies radical changes in marketing (strategies, plans, programs, communication) that have contributed to the development of personal marketing, and thus improved “face to face” communication between bidders and consumers. The theoretical part of the paper refers to defining the role and importance of personalized marketing in the function of improving the business, especially from the aspect of approaching each customer or customer segment individually, as well as the importance of applying social networks to marketing, as well as the specificities and benefits of this type of marketing. The practical part in the focus has the research of the importance and role of social networks in the implementation of personalized marketing, as well as in the process of selecting a tourist destination. The practical part of the paper includes research through a specially designed questionnaire, conducted on the territory of Montenegro, and provides information on how important social networks are for selecting the tourist destination and the offer that a particular destination. The aim of the paper is to draw attention to the importance of a good e-market strategy, also, to the approach that gives the best results in advertising and the achievement of the results of the tourist destination and its offer, sales, communication with consumers, establishment of long-term relationships with consumers, which also affects improvement of the business of every tourist company in general.

Abstract

Due to the fact that dams are considered one of the strategic infrastructures of a country, it is very important to protect it against destructive acts. Accordingly, sensors were used at various points to record structural responses to the dam. Based on the questionnaires completed by experts, accuracy had the score of 3.8 so it was considered as the most important feature of the sensors and the optical fiber sensor with a mean score of 3.93 was selected as the best sensor type among the available ones. For this project, a questionnaire was prepared based on Likert scale and SPSS method was used in TOPSIS software. Then, Seimare concrete double curvature arch dam was simulated in ABAQUS 2017 software and the proper positioning of the sensors for optimum performance was determined based on Finite Element Method analysis and according to structural control criteria such as tension, displacement, strain, velocity and so one.
