Opis:
Previous research showed that accumulations of capital following stationary interest rates are underestimated by human judges. Hyperbolic discounting was suggested as a descriptive and explanatory model for this phenomenon. First, we investigated judged accumulated capital after a period of annual growth and decline. The degree of underestimation increased with accumulated growth and the results supported hyperbolic discounting as a descriptive model on the group level. However, the hyperbolic model did not apply to the data for one third of the participants. Second, we investigated how investment decisions were related to capital accumulation before the investments and to judgments of the possible outcomes of the future investments. To our surprise, the participants’ judgments of expected future accumulated capital did not add predictive power to predictions based on whether there was growth or decline before the investment decision. Unfortunately this strategy leads to suboptimal investment decisions.

Opis:
In modern conditions of urban development, there is a need to improve the technology for determining the investment attractiveness of urban lands by developing a method and models for assessing its impact, which will be based on the construction of a two-level system of indicators, which will determine the integral investment criterion and develop guidelines for improving the investment attractiveness of urban lands. As a result of the research, the value of the integral indicator of urban land investment attractiveness was determined, which allowed to apply it in the system of normative monetary valuation of urban land and to develop methodological recommendations for improving the efficiency of its investment attractiveness assessment. A method for assessing the investment attractiveness of urban land, as the main element of technology, based on the determination of indicators for assessing the integral criterion for the development of guidelines for improving the urban land investment attractiveness is developed. By the value of the integral criterion, the integral indicators of the potential investment attractiveness of urban lands are determined, considering the changes in the normative monetary value of the lands of settlements and the level of investment attractiveness of the regional centers of Ukraine is determined.

Opis:
Foreign direct investment (FDI) and foreign portfolio investment (FPI) have been long considered as independent forms of international capital flows. This paper analyzes the mutual relationship between FDI and FPI and attempts to answer the question whether they complement or substitute for each other from a foreign investor’s point of view. The paper describes the main characteristics of FDI and FPI in terms of their volatility and profitability. We analyze the long-run and short-run relationships between FDI and FPI using vector error correction (VEC) regressions on data for Poland as it is the largest country in Central and Eastern Europe and receives the lion’s share of these two forms of capital in the region. Our investigation suggests that FDI and FPI may be regarded as substitutes. In economically stable periods FDI tends to dominate over FPI but during insecurity and economic distress FPI starts to gain importance

Opis:
Nowadays, there are growing demands on the accuracy of production. Most of this is reflected in precise manufacturing, such as the investment casting process. Foundries are looking for causes of defects in some cases for a very long time, and it may happen that the source of defects is completely different from what was originally assumed. During the casting process there exist potential causes of defects as oxygen inclusions. This paper represents a summary of the beginnings of a wider research that will address the problems of gating systems in investment casting technology. In general, the influence of the melt flow is underestimated and the aim of the whole scientific research is to demonstrate the significant influence of laminar or turbulent flow on the resulting casting quality. Specifically, the paper deals with the analysis of the most frequent types of defects found in castings made of expensive types of materials casted in an open atmosphere and demonstration of connection with the design of gating systems in the future.

Opis:
The effect of cobalt aluminate inoculant addition and melt-pouring temperature on the structure and mechanical properties of Ni-based superalloy was studied. The first major move to control the quality of investment cast blades and vanes was the control of grain size. Cobalt aluminate (CoAl2 O4 ) is the most frequently utilized inoculant in the lost-wax casting process of Ni-based superalloys. The inoculant in the prime coat of moulds and pouring temperature play a significant role in grain size control. The finest surface grains were obtained when the internal surface of shell mould was coated with cobalt aluminate and subsequently pouring was at 1480°C. The influence of selected casting parameters and inoculant addition on mechanical properties was investigated on the basis of tensile, creep and hardness testing. The effect of grain refinement on mechanical properties were consistent with established theories. Tests conducted at ambient temperature indicated a beneficial effect of grain refinement both on tensile strength and hardness. In contrast at elevated temperature during creep, the reverse trend was observed.

Opis:
The present article describes selected aspects of investment casting technology for manufacturing of open-cell aluminium. The main focus is, among others, on the precursor thickening. Two groups of total 30 samples were produced, basing on open-cell polyurethane foam used as the precursor. Each of the two sample groups was thickened with a different type of suspension consisting of carbonaceous substances and organic binders. The influence of the coating mixture type was compared, leading to conclusions regarding the desired composition and fluidity of the suspensions. Both sample groups of the obtained open-cell aluminium had stochastic cell distributions, the average pore diameter was 5.2 mm and the PPI index was 8. The apparent densities were respectively: 0.485 g/cm3 and 0.312 g/cm3 , which reflected the impact of the precursor coating. Additionally, samples from both groups differed in quality.

In this study, effects of political stability, economic freedom and trade freedom of above-stated Fragile Five Countries consisting of Brazil, Indonesia, India, Turkey, and South Africa on the performance of FDI appeal was analyzed with first generation panel data analysis method for the 1996-2017 period. The cointegration analysis between series was conducted by means of Kao (1999) and Pedroni (2004) test. The analyses showed that political stability and trade freedom have a significant positive coefficient on the Fragile Five Countries’ FDI. It was also determined that the impact of economic freedom on FDI was statistically insignificant. Thus, it was concluded that the most important determinant of FDI entry into countries is political stability. Error correction mechanisms of models have been working well. In addition, it was found that political stability, economic freedom, and trade freedom are the cause of foreign direct investment in the long-run

Opis:
Investments towards sustainable development are vital for the future and they must be carefully planned to deliver immediate and long-term benefits. Hence, the ability to communicate the forms of impact of sustainable investments to local societies, people, investors and other stakeholders can provide a competitive advantage. However, the assessments are often under pressure to demonstrate short-term effects rather than emphasise the long-term impact. In addition, indirect and intangible forms of impacts should not be measured solely in economic terms. This paper proposes an assessment framework to support the integrated economic and social impact assessment of sustainable investments aimed at improving physical and socio-economic wellbeing. The framework is demonstrated in two case studies: new construction and renovation investments in affordable housing and social impact investment in sustainable development. The investments in the case studies are evaluated, selected and prioritized not only in terms of money but also with regard to sustainability, social acceptability and their overall impact on society, as a whole. The results indicate that a systematic integrated assessment of monetary and non-monetary factors can be successfully combined with the sustainable development decisions.

This paper shows the results of studying the technology of manufacturing cortical electrode-instruments (EI) with the use of indirect methods of the Rapid Prototyping technology. Functional EI prototypes were made by layered synthesis of the photopolymer material with the use of the stereolithography technology (SLA - Stereo Lithography Apparatus). The article is focused on two methods of indirect EI manufacturing. One of the EI prototypes was used for making a molded wax model for hot investment casting, followed by applying copper coating. The second prototype was used for applying copper plating to a prepared current-conductive layer. As a result of EDMing a steel workpiece, both EIs reached the desired depth, which is 1 mm. The copper plating applied to the EI preserves its integrity. Through the use of the casting technology, there is a possibility to cut the economic costs by 35%. Using a prototype with preliminarily applie conductive coating makes it possible to make geometrically-complex EIs.

The casting workshop was discovered with numerous artifacts, confirming the existence of the manufacturing process of metal ornaments using ceramic molds and investment casting technology in Lower Silesia (Poland) in 7-6 BC. The research has yielded significant technological information about the bronze casting field, especially the alloys that were used and the artifacts that were made from them. Based on the analyses, the model alloys were experimentally reconstructed. Taking advantage of the computer-modeling method, a geometric visualization of the bronze bracelets was performed; subsequently, we simulated pouring liquid metal in the ceramic molds and observed the alloy solidification. These steps made it possible to better understand the casting processes from the perspective of the mold technology as well as the melting and casting of alloys.

Opis:
During the planning and controlling of the construction process, most attention is focu sed on risk analysis, especially in the context of final costs and deadlines of the investment. In this analysis, the primary and most significant concern is the proper identification and quantification of events, which on a certain level of probability may affect the development process. This paper presents the result of a risk analysis for a particular building object, made after completion of the investment and accepting it for use. Knowledge of the planned values and the actual investment process allowed for the identification of the events and their effects that in this case have significantly disrupted the investment process. The limited total cost of the investment project in question had a considerable impact on the progress of the project execution. Despite three transitions of administrative procedures, the opening date of the shopping centre was delayed by only three weeks.
