The influence of railways on spatial layouts of settlements in North-Eastern Poland
Authors: Dragan Weronika 
Published: May 2018

Abstract
The aim of the study was to analyse the transformation of spatial structures of towns in North-Eastern Poland, characterized by different origins and happening due to the construction of railway line. The region in question was in the past subject to different settlement processes taking place against the background of historical events such as, among others, the conquest of land by the Teutonic Knights and the political partition of Poland (the border between Prussia and Russia), thereby forming diverse urban systems, later influenced by the railway, which modified their spatial structures, as well as changed their existing importance in the region. As a result of aforementioned changes different forms of urban layouts were formed - line layouts within the historic towns and more complicated layouts within the new railway settlements. The entire analytical procedure was based mainly on archival cartographic materials and divided into three parts: conditions of settlements development, analyze the evolution of its spatial layouts and the typology of researched urban layouts. The chronological summary of the parts allowed for the comparison of the spatial structure of a given town and for its interpretation. In addition, field research necessary for the interpretation of the contemporary structures of chosen towns was carried out. The final result was a synthesis of research in the form of a typology of links between the original structure and the railway station, distinguishing between the different forms of settlements.

Abstract
In conditions of intense competition, it is not enough to achieve only customer satisfaction. The marketing-oriented companies must be focused on building long-term customer loyalty. Creation and delivery of superior values are the key activities to achieve and maintain competitive advantage. This study seeks to examine how the different value dimensions of travel agencies' services affect both dimensions of loyalty: the intention of using the same services again and recommending them to others. Primary data were collected through questionnaire method. In the study, descriptive statistics, correlation and multi-point regression were used for data analysis. The results of survey point out two key dimensions of perceived value that achieve a statistically significant effect on loyalty: quality of interaction and value for money. Identification of key dimensions of perceived value as an initiator of loyalty is essential for service-oriented companies, because in this way they increase opportunities for improving business relationships with clients, in the future.

Published: May 2018

Abstract
The positive achievements of the globalization process is the awareness of the imminent protection and preservation of the environment, and the consequent health tourism, as a kind of organized movement of people to meet the needs of living in a “pristine nature” and satisfying the need for clean water, food and air. It is a little-known, easily accessible wilderness areas in the world. Environmental values through such places, such as the specific characteristics of space, good climate, hydrographic resources and other natural features can be a good basis for the development of health and recreational tourism in the future. In this sense, national, and increasingly local communities should be responsible for the selected type and pace of tourism development in terms of directing the long-term quality and complex interaction between the tourist offer, tourist demand and the environment in general. Strategic vision, in this context, involves the application of eco-management, both in the field of tourism policy, as well as in the domain of politics at the level of individual holders of tourist attractions. With that in mind, this paper presents the possibilities of development of health and recreational tourism in spas and mountain resorts, and points to the role in this development, there should be an eco-management, especially if we take into account the fact that in today's terms of increased tourist demand for healthy and intact natural areas.

According to this law the owner of the agricultural land in Slovakia may, without further restrictions, transfer the agricultural land only to (a) a buyer who has been active in the food business or exercises agricultural activity („Farmer“) in the municipality where the agricultural land is situated for at least three years prior to the transfer; (b) the existing co-owner of the agricultural land; or (c) persons related to the owner, in the event that the owner is a natural person
Impact of ectohumus application in birch and pine nurseries on the presence of soil mites (Acari), Oribatida in particular
Authors: Klimek Andrzej , Rolbiecki Stanisław , Rolbiecki Roman 
Published: May 2018

Abstract
Intensively used forest nurseries are characterised by degradation processes that lead to a drop in the quality of seedlings. The main reason of this problem is a decrease in biological soil diversity. Therefore, an attempt of nursery soil enrichment by introducing ectohumus – as compost and fresh litter – from the pine forest was carried out. The research was carried out in 2009–2011 in the Bielawy forest nursery near the city of Toruń, Poland. The objective of the study was to determine the impact of organic fertilisation (compost made up of forest humus) and mulching using fresh ectohumus on the density and community composition of Acari mites and on species composition of oribatid mites (Oribatida) in the nurseries of silver birch and Scots pine. Mites, especially oribatid mites, were treated as bioindicators of soil biological activity. Research has shown that mulching using fresh ectohumus caused a multiple increase in the density of mites, especially in saprophagous mites Oribatida. Oribatid mites were clearly more numerous in birch cultivation than in that of pine. Overall, 27 species of oribatid mites were found. Mulching resulted in a significant growth in species diversity in both cultivations. The most numerous oribatid mite in the area under the study was Oribatula tibialis. This species was present in all plots and showed clear preference for birch cultivation. Tectocepheus velatus and Oppiella nova, common and known to be present in a variety of environments, were slightly less numerous.
Influence of seed priming and water stress on selected physiological traits of borage
Authors: Dastborhan Soheila , Ghassemi-Golezani Kazem 
Published: May 2018

Abstract
Borage is a valuable medicinal plant with various constituents in leaves, flowers and seeds. Hence, it is important to improve the performance of this medicinal plant under different environmental conditions. Thus, two field experiments were arranged as split-plots based on a RCB design with three replications in 2012 and 2013, to evaluate the effects of seed priming and different irrigation intervals on selected physiological properties of borage leaves. Irrigation intervals (irrigation after 60, 90, 120, 150 mm evaporation from Class A pans, respectively) and priming treatments (control, water, KNO3 and KH2PO4) were allocated to the main and sub plots, respectively. The chlorophyll content index was enhanced under limited irrigation treatments, mainly due to a decrease in leaf area index and intercepting more radiation. However, the membrane stability index was stable under different irrigation intervals. Decreased relative water content and leaf area index and increased leaf temperature under lower water availability led to some reductions in the grain yield of borage. All of the priming techniques, particularly hydro-priming, enhanced the seedling emergence rate, leaf area index and consequently grain yield per unit area. Therefore, seed hydro-priming can be used to improve the field performance of borage, particularly when sufficient water is available.
The Role of Signals in Online Auction Purchase Decisions
Authors: Cypryjański Jacek , Grzesiuk Aleksandra 
Published: May 2018

Abstract
There is a growing interest in behavioural economics contradicting the empirical prediction of rational choice theory once applied to online auctions. The issue is of particular relevance due to the large use of online auctions and the anticipated growth in the future. Online auctions combine the conventional auction model with information technology. However, information asymmetry within such auctions causes risks and uncertainties that influence consumer purchase intentions. The research investigates online consumers’ behaviour. The Authors suggest that due to the high perceived risk of the online buying process consumers are prompted to use cues of seller’ reputation. In a series of six experiments conducted via the auction site Allegro.pl in Poland a number of signals from auction web pages has been manipulated to influence purchase intention. The results suggest that several signals can be used to stimulate online customers’ behaviour. The results of these experiments indicate that buyers are more susceptible to the influence of “visual” signals than signals that require greater involvement of the buyer (to read information). The conducted experiments contribute to a more comprehensive understanding of online auction users’ behaviour. And finally it provides some managerial implications to increase online auction effectiveness from the seller’s perspective.
Testing Integration Effects Between the Cee and U.S. Stock Markets During the 2007–2009 Global Financial Crisis
Authors: Olbryś Joanna , Majewska Elżbieta 
Published: May 2018

Abstract
The main goal of this paper is to explicitly test a research hypothesis that there was no integration effect among the U.S. and the eight Central and Eastern European (CEE) stock markets during the 2007-2009 Global Financial Crisis (GFC). As growing international integration could lead to a progressive increase in cross-market correlations, the evaluation of integration was carried out by applying equality tests of correlation matrices computed over non-overlapping subsamples: the pre-crisis and crisis periods, in the group of investigated markets. The crisis periods are formally established based on a statistical method of dividing market states into bullish and bearish markets. The sample period May 2004-April 2014 includes the 2007 U.S. subprime financial crisis. The robustness analysis of the integration tests with respect to various data frequencies is provided. The empirical results are not homogeneous and they depend both on the integration test and data frequency. Consequently, it is not possible to conclude whether integration between the investigated markets is present.
The Influence of Profitability Ratios and Company Size on Profitability and Investment Risk in the Capital Market
Authors: Rutkowska-Ziarko Anna 
Published: May 2018

Abstract
A study was conducted of 15 food companies listed on the Warsaw Stock Exchange. The profitability of companies was measured by: return on assets (ROA), return on equity (ROE) and return on sales (ROS). Investment risk was measured by standard deviation and semi-deviation. The main objective of the study was to examine whether the average level and variability of selected indicators of profitability are reflected in the average level and the variability of returns on the capital market. An additional aim was to examine whether the size of the company affects the profitability and risk of investment in stocks as well as the average value and the volatility of profitability ratios. A positive correlation between the average value of the profitability ratios (ROA and ROS) and the average rates of return on the capital market was identified. Similarly, companies with higher volatility and semi-volatility of profitability ratios were simultaneously characterized by larger fluctuations in rates of return on the stock market. Studies have shown that the size of the company is negatively correlated with the risk of stock market investments and the volatility of profitability ratios.
Diversified Price Dynamics in some Sub-Segments of the Housing Market
Authors: Kokot Sebastian G. 
Published: May 2018

Abstract
The observation of price movements on the real estate market is an extremely difficult task as we have to face problems belonging to two spheres. The first of them is the specific nature of real estate as marketable objects and of the real estate market itself. The second one is the character and quality of data on real estate transaction prices. In this article the author, based on an empirical study, attempts to prove that even in a single segment of a local real estate market the prices in individual sub-segments can fluctuate with different intensity. The range of price movements can be so vast that it seems pointless to apply a single averaged price index for the whole segment, and usually that is what analysts do.

Authors: Papis Magdalena , Mokrzycki Tomasz 
Published: May 2018

Abstract
The aims of this study were to demonstrate the role of forests in the Roztoczański National Park as a refuge for rare and endangered saproxylic Coleoptera as well as recognition of entomological fauna related to dead wood. The study was conducted in the strictly protected are of Bukowa Góra from 20th April to 30th September 2012 and focused on the wood of beech and fir. We inventoried saproxylic beetles by means of nine ‘Netocia’ traps, which resulted in a total of 135 recorded species, of which 52 had not been reported in the park before. Twenty-one rare and endangered species were found. The high number of new species in the Roztoczański National Park indicates a high biodiversity value of the area. Our studies therefore show that the strictly protected area of Bukowa Góra is a biodiversity hot spot of saproxylic Coleoptera.

Abstract
This paper presents results of a meta-analysis on the theoretical and economic aspects of using wood biomass for the production of energy in Poland. The source data used in the analyses were obtained from various official sources and statistics as well as previously published scientific studies. The results lead to the conclusion that the wood biomass supplied for energy production in the year 2012 amounted to a total of 18 million cubic meters, of which forestry supplied 6.8 million m3, the wood industry 6.5 million m3 and public utilities provided 4.5 million m3.
Resources of dead wood in the municipal forests in Warsaw
Authors: Skwarek Konrad , Bijak Szymon 
Published: May 2018

Abstract
Dead wood plays an important role for the biodiversity of forest ecosystems and influences their proper development. This study assessed the amount of coarse woody debris in municipal forests in Warsaw (central Poland). Based on the forest site type, dominant tree species and age class, we stratified all complexes of the Warsaw urban forests in order to allocate 55 sample plots. For these plots, we determined the volume of dead wood including standing dead trees, coarse woody debris and broken branches as well as uprooted trees. We calculated the amount of dead wood in the distinguished site-species-age layers and for individual complexes. The volume of dead matter in municipal forests in Warsaw amounted to 38,761 m3, i.e. 13.7 m3/ha. The obtained results correspond to the current regulations concerning the amount of dead organic matter to be left in forests. Only in the Las Bielański complex (northern Warsaw) volume of dead wood is comparable to the level observed in Polish national parks or nature reserves, which is still far lower than the values found for natural forests. In general, municipal forests in Warsaw stand out positively in terms of dead wood quantity and a high degree of variation in the forms and dimensions of dead wood.

Published: May 2018

Abstract
Drought is a significant factor limiting crop production in arid regions while hawthorns (Crataegus sp.) are an important component of such region’s forests. Therefore, treatments that increase hawthorn drought resistance may also increase transplanting success. Thus, the physiological and biochemical responses of hawthorn seedlings to a factorial combination of different concentrations of silica nanoparticles (SNPs at 0, 10, 50 and 100 mg L−1) and three soil moisture treatments (without stress, moderate stress and severe stress) were investigated. Seedlings were irrigated with one of the four concentrations of SNPs for 45 days before exposing them to drought stress. Photosynthesis parameters, malondialdehyde (MDA), relative water content (RWC), membrane electrolyte leakage (ELI) as well as chlorophyll, carotenoid, carbohydrate and proline content were determined. At the end of the experiment, positive effects by SNP pre-treatment on physiological indexes were observed during drought stress. Under drought conditions, the effect of SNPs on photosynthetic rate and stomatal conductance was evident. Although the SNPs increased plant biomass, xylem water potential and MDA content, especially under drought conditions, RWC and ELI were not affected by the SNP pre-treatments. Seedlings pre-treated with SNPs had a decreased carbohydrate and proline content under all water regimes, but especially so under drought. Total chlorophyll content and carotenoid content did not change among the treatments. Generally, the findings imply that SNPs play a positive role in maintaining critical physiological and biochemical functions in hawthorn seedlings under drought stress conditions. However, more studies are needed before the physiological and biochemical basis of induced drought resistance can be determined.
Latitudinal variability of the radiation microclimate in artificial forest gaps in Poland – the modelling perspective
Authors: Bolibok Leszek , Brach Michał , Drozdowski Stanisław , Szeligowski Henryk 
Published: May 2018

Abstract
The aim of the study was to characterize latitudinal changes in the radiative microclimate of small forest openings (artificial gaps) under Polish conditions. The global, direct and diffuse radiation on the forest floor in gaps was modelled using the Solar Radiation tool in ArcGiS 10.2 Esri. The gaps were modelled as holes of elliptical shape (60 m × 40 m diameters) in flat terrain and with a depth of 20 to 30 meters to mimic the height of a surrounding tree stand. The range of global radiation diversity on an open and flat surface predicted by our model was comparable with findings of empirical studies. Theoretically, the investigated gaps in the northern-most part of Poland receive only 82% of global solar radiation, 74% direct and 90% of diffuse radiation compared to gaps in the most southern part of the country. The comparison with empirical data indicates that local values of the transmittance parameter of the atmosphere may have a large influence on the actual values of solar radiation and may partially mask the latitudinal impact. Nevertheless, the model constitutes a valuable tool for characterising solar radiation diversity in a gap and supports silvicultural decision-making.
Ways to use silver birch Betula pendula Roth regeneration in sites considered for stand conversion due to decline of Norway spruce Picea abies (L.) H. Karst. in the Silesian Beskid Mountains

Published: May 2018

Abstract
One of the tree species appearing after a decline of Norway spruce Picea abies (L.) H. Karst. in the Silesian Beskid Mountains is Silver Birch Betula pendula Roth. Therefore our study was aimed at evaluating this birch regeneration and the dynamics of changes resulting from experimental cutting. Measurements and inventories of trees were conducted on research plots located in a ten-year old birch regeneration site with either no cutting, partial cutting (50%) or clear cutting (100%) of birch. We observed an introduction of biocenotic species (rowan, willow, aspen) as well as the target species (spruce, fir, beech) under the birch canopy. Fir and beech were also planted, because of their slow natural regeneration. The clear cut treatment caused a great number of sprouts growing from birch stumps, reaching a height of about 2 m over 3 years, resulting in competition with the regeneration of other species. Partial cutting did not cause such a drastic amount of sprouting. Furthermore, we found that only the spruce height increment is significantly less under a birch canopy compared to open space. The obtained results indicate a necessity to adjust the density and species composition of regenerating tree species under a birch canopy, avoiding complete removal of the first generation birch cover and the need to moderately thin out birch.

Published: May 2018

Abstract
Paulownia Siebold et Zucc., a widely distributed native genus, has been commonly used in the furniture. The color of wood is a very important aesthetical property, and it has a fundamental influence on the commercial value of timbers. Therefore, it is critical for forest managers to select elite Paulownia clones based on the color of wood. Eighteen 5-year-old Paulownia clones grown in a hilly area in Hubei Province, China were examined in terms of color values (L*, a*, b*), color difference (ΔE*), and Hunter lab space whiteness (W) using a Chroma meter CR-400. Differences in color parameters among the 18 clones were analyzed and clustered. The results showed that the ranges of L*, a*, b*, ΔE*, and W were 77.19-80.38, 3.60-4.84, 13.79-15.69, 17.92-21.37, and 68.92-72.42, respectively. The color parameters significantly differed among the examined clones. Differential and cluster analyses indicated that clones 204, 605, 702, and 603 had higher L*, W, and lower ΔE*, rendering these as elite clones with superior color properties.
