The main problem of this paper to be solved is to outline one of the main cultural institutions - namely schools - in terms of firms. In order to achieve this goal, the basic characteristics of firms had to be established, also analysing the most important problems related to them. The paper claims that, in fact, all firms overlap and thus depend on each other, which inevitably limits their competition to a certain degree. This is especially true for cultural institutions in the process of producing human capital. The authors propose to use rather strategic coordination instead of internalisation in the process of treating externalities.

This paper presents an automated model and a project, Arrakis, for finding defects in shading algorithms for graphics rendering and compute workloads. A key challenge in shading algorithm testing is the lack of an oracle that can determine the quality and the output of a custom shading algorithm; this is crucial in graphics workloads because expensive assets are often wasted on solving these problems. A broad solution, Arrakis is developed, which builds on current graphics technology advances in Vulkan, SPIR-V and SPIRV-X by leveraging the standardization with mappings from SPIR-V and C++. Findings show that utilizing the demonstrated technology can improve quality whilst increasing productivity.

Abstract

Increasing food demand poses a challenge for the economy and places a burden on the environment. In agricultural food production, each product chain stage shows scarce resources and negative environmental impacts are becoming increasingly significant. Food consumption has a significant impact on the environment and on human health. Sustainable food consumption is characterised by health and environmental consciousness. This study focuses on the relationship between perceived and real consciousness – more specifically on environmental and health consciousness – concerning food consumption. Following a concise overview of the conceptual background, the definitions of conscious consumption, conscious food consumption, health conscious consumer and environmentally conscious consumer behaviour are explained based on the available literature. The primary research draws conclusions from the results of a 500-person questionnaire survey among the students attending the University of Debrecen on the relationship between perceived and real health and environmental consciousness regarding food consumption. It was concluded that environmental consciousness (10.0%) was less characteristic of students than health consciousness (18.2%); the relationship between perceived and real consciousness is significant; the role of price in determining food purchases is less pronounced for those claiming to be self-conscious food consumers than those who are neither health conscious, nor environmentally conscious.

Abstract

Experimental investigations of laminated timber-concrete and steel-timber-concrete composite floor or bridge beams show that complex failure modes develop in such members. This paper presents acoustic emission investigation results that reveal the development of the failure modes in the steel-timber-concrete composite specimens subjected to short-term static ramp-loading. Accelerometers connected to a four channel dynamic signal analyzer continuously monitored the beam specimens during the load tests. Conventional techniques can be used for time domain data acquisition and evaluation of acoustic emission events generated in the structural member investigated, which contain thousands of independent signals to be processed, even if only in the audible frequency range. While the wavelet series of detected acoustic emission signals in the time domain produce a reliable amount of statistical information about the number and intensity of events, a frequency - time domain visualization may facilitate an advanced interpretation on the basis of spectrogram analysis. With on-site collection of data the methodology could allow for structural monitoring.
