Abstract

In this study the financial situation of leading Hungarian construction companies in Hajdú-Bihar County is analysed for the period of the economic crisis. The target group is determined by the amount of share capital and sales, thus it contains the most relevant regional companies. Their main activity is residential and non-residential building construction. The most significant purpose of the research is to analyse the changes of the comparative financial situation of these companies. Moreover, I specify the main characteristics of the regional sector, and determine the competitive advantages of the companies. The research method is based on annual financial reports. In order to evaluate the performance of the examined companies I use financial ratios concerning liquidity, efficiency, and profitability situation. At the end of the study I summarize conclusions and identify the most important consequences regarding the changing financial position of competitors.

Abstract  

Rhyolite-rhyodacite tuff samples were analysed by X-ray powder diffraction, ICP-OES and thermogravimetric (TG) methods to determine mineral and major element composition as well as different types of bound water, respectively. Similarly to CIA values, some TG parameters (H2O[I] — water released up to ca. 200–220°C; H2O[III] — water loss above 500–550°C and H2O[I+III]) show positive correlation to the amount of secondary minerals. Moreover, these parameters are in close positive correlation to CIA values. Our results suggest that TG determination of different types of bound water may serve as a useful tool for estimation and characterisation of alteration degree of rocks.

Abstract  

The aim of the current paper is to map minerals mainly of Carpathian obsidian glasses by nuclear microprobe based on the particle induced X-ray emission (PIXE) providing analytical data on them for the first time. Some samples from Armenia, Greece are also involved to make a comparison with the Carpathian specimens. The following minerals are identified and analyzed: pyrrhotite, chalcopyrite, pyrite, zircon, pyroxene, biotite, plagioclase feldspar, and anhydrite. On the basis of rock-forming silicate minerals, some petrologic processes are outlined. With the identification of accessory minerals (anhydrite, pyrrhotite, chalcopyrite, pyrite), some geological conclusions are also drawn.

The paper is a short summary of the main archaeological outcomes of an interdisciplinary project in a section of the Drava river crossing the territory of Somogy county, in Hungary. One of the study areas is the vicinity of Berzence where medieval settlement patterns, land use and economy have been reconstructed on the basis of historical sources and an archaeological field survey. A comprehensive review of architectural history and material culture of the Ottoman Period stronghold in Barcs was the other area under investigation. Research there was based on written sources and the archaeological assemblage recovered from the palisaded fort. Zooarchaeological research at this site revealed some significant culture historical aspects of this stronghold. Underwater archaeological investigations carried out in the Drava river itself and aerial exploration of the study areas also supplied valuable archaeological results.

Background

This study examines the Kerns’ Security Scale (KSS) that is a self-report questionnaire to assess school-age children’s certain family-related experiences, and is widely used in the United States and in certain European countries.

Objectives

The aim of the present investigation is to review the factor structure of the KSS in Hungarian population and to describe the characteristics of the scales in an Eastern-Central European country, as well as to check its external validity by the Child Depression Inventory, and to evaluate its feasibility in clinical practice and school psychology services.

Methods

The sample consisted of 323 primary and secondary schools students (137 boys and 186 girls), aged 10–18 years. They completed the Kerns’ Security Scale and the Child Depression Inventory.

Results

statistical analysis has revealed that the items of the security questionnaire can be divided into three subscales, namely: Reliance, Availability, and Autonomy support. The mothers’ subscale scores are higher than fathers’ subscale scores (Reliance: t = 7.1, p < .001; Availability t = 8.9, p < .001; Autonomy support t = 3.2, p < .01).

Conclusion

The results supported the three factor model of the KSS, and recommended to apply for clinical practice and in school psychology services.
