Environmental Laboratory of the Department of Archaeology at the University of Hradec Králové – History, Present and Plans for the Future
The Centre for Fieldwork Archaeology of the Department of Archaeology, Philosophical Faculty, University of Hradec Králové, is developing a new environmental laboratory. It is focused on the application of several methods in large-scale rescue excavations on large infrastructure construction sites. The methods are focused on geochemistry – with wavelength dispersive X-ray fluorescence (WD XRF) as its main method of analysis, and optically stimula…
Digital twin-based cyber-physical manufacturing systems, extended reality metaverse enterprise and production management algorithms, and Internet of Things financial and labor market technologies in g…
Research background: Generative artificial intelligence (AI) and machine learning algorithms support industrial Internet of Things (IoT)-based big data and enterprise asset management in multiphysics simulation environments by industrial big data processing, modeling, and monitoring, enabling business organizational and managerial practices. Machine learning-based decision support and edge generative AI sensing systems can reduce persistent labor…
Exploring CSR performance as a proxy for competitive ad-vantage across sectors in the Central European countries
Research background: Corporate social responsibility (CSR) demonstrates that a business should be interested in broader social issues rather than on merely those impacting profit margins. Thus, enterprises across all sectors need to focus on the pillars of CSR, which can ultimately give them a competitive advantage. Previous research papers have focused mainly on the level of CSR in particular industries or how CSR activities are communicated in …
Anthropogenic soils in a marginal landscape – Fortified manorial sites in the woodland edge zone in western Czechia
Neolithic long barrows were built on the margins of settlement zones as revealed by elemental soil analysis at four sites in the Czech Republic
Making Informed Decisions in the Volatile Crypto Market
Despite widespread skepticism linked to cryptocurrencies, they are constantly gaining the interest of scholars, investors, media, and regulators. Recognizing the importance that portfolio risk maintains for crypto participants, this study attempts to shed light on this issue. We investigate the risk-return tradeoffs of the most tradable cryptocurrencies based on portfolio diversification techniques. Three different crypto portfolios containing a …
Earnings management model for Visegrad Group as an immanent part of creative accounting
Research background: Creative accounting practices do not frequently violate the law and are not considered illegal; however, accounting managers may exploit legal ambiguities to portray the company's financial standing in accordance with management preferences. Therefore, the analysis is focused on the detection of earnings management in companies operating in the Visegrad Group, which represents one of the most commonly used techniques for reve…
The contribution of Posl and PXRF to the discussion on sedimentary and site formation processes in archaeological contexts of the southern Levant and the interpretation of biblical strata at Tel Burna
Adaptation of small and medium-sized enterprises in the service sector to the conditions of Industry 4.0 and Society 4.0
Research background. The need for an in-time, efficient and effective adaptation of small and medium-sized enterprises in the service sector to the technical, economic, social and environmental conditions of Industry 4.0 and Society 4.0 is a current problem caused by the introduction of new information and communication technologies, cyber-physical systems and artificial intelligence into all economic industries and areas of human life. The adven…
Random walks and market efficiency tests
Research background: Covid-19 has affected the global economy and has had an inevitable impact on capital markets. In the week of February 24?28, 2020, stock markets crashed. The index FTSE 100 decreased 13%, while the indices DJIA and S&P 500 fell 11?12%, the biggest drop since the 2007?2008 financial and economic crisis. It is therefore of interest to test the random walk hypothesis in developed capital markets, European and also non-European, …
Study of legislative and administrative obstacles to SMEs business in the Czech Republic and Slovakia
Research background: SMEs represent an integral part of the economy environment in a majority of the countries all over the world. They signify the most efficient, progressive, and important part of the advanced economies. The long-term effort of the EU countries, as well as other advanced economies is to create quality and stable conditions for their development in order to be able to respond to all the possible changes in the business environme…
Soil Chemistry to Support Old Map Analysis of the Built-up Area of an Abandoned Settlement. Case Study from the Romanian Banat
This paper focuses on the combination of geochemical methods and old map analysis to study landscape and settlement development. It is well known that historical land use of abandoned rural settlements affects soil chemistry and vegetation composition. We wanted to find out whether it is possible to distinguish various historical land uses when we know the current chemical composition of the soil; in particular, whether it is possible to recogniz…
Human burials can affect soil elemental composition for millennia-analysis of necrosols from the Corded Ware Culture graveyard in the Czech Republic
The dynamics of a non-forested stand in the Krušné Mts
Multi-element mapping of anthropogenically modified soils and sediments at the Bronze to Iron Ages site of Tel Burna in the southern Levant
Large Scale Geochemical Signatures Enable to Determine Landscape Use in the Deserted Medieval Villages
Pedogenesis, Pedochemistry and the Functional Structure of the Waldhufendorf Field System of the Deserted Medieval Village Spindelbach, the Czech Republic
Spindelbach was a Waldhufendorf type of village, i.e. every household could manage its own fields independently of other households. Our study has importance for research on the economic and social development between the Medieval and Modern Era and for studies of human impact. Performing soil and geochemical mapping, we have identified four geochemical factors in a clearly interpretable pattern: 1) general geology and soil environment (represent…
