Opis:
It is possible to make analyses within the field of GIS applying cellular automata. One of the purposes of socio-economic geography is indirect understanding of the phenomenon by analyzing spatial patterns and inferring spatio-temporal processes looking rather for local hotspots. The cellular automata are the tool both for spatio-temporal inferring based on local conditions and data visualization. The evidence is the case study of spatial simulation of Warsaw Urban Area (Poland). The author verifies the hypothesis that the present layout and extent of the Warsaw agglomeration determines further directions of the city's spatial development. To this end, he employs a method based on cellular automata theory.

Tematy:

Opis:
The dependency of land use and the neighbouring land cover patches is related to the existing neighbourhood or the predominant land use types in a given region, which stimulates further land changes of the lot being observed. Land use changes can be considered a complex and (to an extent) random process. The complexity of interactions means that the conventional deductive models are constrained, particularly in the case of the spatio-temporal phenomena, and implies the application of cellular automata to spatial research. Cellular automata are similar to the map algebra models in GIS. The concept of using neighbourhood coefficients in the analysis of land use changes is based on the combination of map algebra with two-dimensional cellular automata. The aims of this research included formulating the theoretical structure of neighbourhood coefficients, analysing their operationalization and testing their practical application. The verification of research and procedures included maps and statistics of simulations of land use changes in Poland.

Opis:
The development of information and communication technologies (ICTs) has significant economic and social impacts at both the global and regional level. Some of these implications have been perceived as positive and unexpected. While both the positive and negative social and economic impacts have been highlighted in the literature, opinions on these impacts remain ambiguous. Those aspects considered to be advantageous include faster communication, ease of use, development in the range of services and revenues, and an increase in individuals’ free time allowance. ICT penetrates all branches of the economy as a set of general purpose technologies. New information and communication technologies ease everyday life, serve as tools to help people in extreme situations, e.g. accidents, illnesses or natural disasters, and are also the pillars of contemporary entertainment media. The usefulness of ICT has been stressed and loudly disseminated to a large extent by the media. On the other hand, these new technologies sensitize society in quite new ways to the well-known natural hazards that people have encountered in the past.

Opis:
Values define the directions of human activities and are related to people’s motivation to undertake specific activities and roles (Schwartz, 1994; Brown, 2002). Researchers and employers observe differences in motivation to work among representatives of different generations and genders (Twenge, Campbell, & Freeman, 2012; Gursoy & Karadag, 2013). In this research project, the authors asked what motivated contemporary employees, whether the intensity of their motives was different in different generations, what relationships there were between the dominant work motives and employees’ dominant values, and whether there were differences between women and men regarding work motives. To verify the hypotheses, they conducted a study with a sample of 307 professionally active people. They used their own Types of Work Motives Questionnaire designed for the purposes of the study and the Valued Living Questionnaire (VLQ; Wilson & Murrell, 2004). The obtained results indicate that younger employees choose the kind of work that gives them comfort and adequate pay. Regardless of age, however, social security support is the most important for all groups of respondents. For women, security and social security support are important at work. Moreover, the study has shown that there is a relationship between work values and work motives. For example people who appreciate values such as friendship and stability are motivated to work by good relationships and security, those who value recreation and stability are motivated by comfort and salary, those for whom respect and education are crucial are motivated by the possibility of development etc.

Opis:
A two-career marriage is a modern family model, within which both partners pursue a career as employees, often in leadership positions, but also a career associated with holding specific roles in the family, marriage and the household. The aim of this study was to verify the relationship between the level of work engagement and the subjective quality of marital relationships. Moreover, the research attempted to find variables which may mediate the relationship, such as levels of occupational stress experienced, conflict / facilitation of occupational and personal roles and gender. The study was conducted among 150 two-career married couples, with both partners working actively on the competitive labour market, often holding leadership positions and balancing their professional and family roles. All of the participants, aged 28 to 40, had completed higher education and had at least 1 child. The study used the Work-related Behaviour and Experience Pattern Test (AVEM), Well-Matched Marriage Questionnaire (KDM-2), Stress Questionnaire and the Questionnaire of Work and Family Balance. Statistical analysis indicated that work involvement of two-career couples positively contributes to increasing the subjectively perceived quality of their marital relationships. The level of occupational commitment also has a positive relationship with the level of stress experienced and work – family conflicts. Such stress and conflicts are important mediators in the positive relationship between work involvement and the quality of marital relationship. Therefore, if the partners’ work is linked to significant stress, generating additional work-family conflicts, it may consequently negatively affect the quality of marital relations of the dyads.

Wettability of the surface of bacterial cellulose film modified with low energy ion implantation The paper presents the preliminary results of the modification on the water wettability of cellulose, using ion implantation method. Two kinds ions of the noble gases, i.e. helium and argon were implanted with fluences of 1e15 nand 1e16 cm-2, and with the ion energy of 60 keV. The measurements of the contact angle values show the different influence of both types ions on the hydrophobicity of the modified cellulose, but the hydrophobicity of implanted cellulose increases in all cases. The real investigations were supplemented with the modelling results of the depth profiles of the implanted ions and the main parameters of the modelled peaks.
Zwilżalność powierzchni celulozy bakteryjnej modyfikowanej metodą implantacji jonów. Artykuł przedstawia wstępne wyniki modyfikacji na zwilżalność wodą implantowanej jonami celulozy. W badaniach wykorzystano dwa rodzaje gazów szlachetnych, tj. hel i argon. Implantowane dawki wynosiły 1e15 i 1e16 cm-2, a energia jonów 60 keV. Pomiary kąta zwilżania pokazują różny wpływ obydwu typów jonów na hydrofobowość modyfikowanej celulozy, jednakże hydrofobowość wzrasta we wszystkich przypadkach. Badania zostały uzupełnione wynikami modelowania głębokosciowych profili implantowanych jonów i głównych parametrów modelowanych pików.

Influence of the ion implantation of nitrogen and selected metals on the lifetime of WC-Co indexable knives during MDF machining. The paper presents the results of durability tests for WC-Co indexable knives during the machining of MDF. The knives were implanted with nitrogen, zirconium, molybdenum and tin, using MEVVA type implanter with non-mass separated beam. Additionally, the Monte Carlo simulation results of the main parameters of the depth profiles of the implanted elements are presented in this paper. A higher correlation of tool life with the project range and range straggling than with the parameter of the peak volume dopant concentration was demonstrated.
