The starting point of the study on the problems, dilemmas and hopes for effective implementation of revitalization projects in Polish cities was the conviction that revitalization is one of the processes affecting the development and changes in the spatial and functional fabric of cities. Revitalization is defined as a deliberate and purposeful process, the effect of which is to restore life in the dysfunctional and degraded parts of cities. Taking up such a topic required an answer to the question about the nature of revitalization and its aspects. The focus of the study was on the problems of revitalization that stem from the legal and socio-economic situation and the dilemmas faced by local government authorities of Polish cities. The introduction to these considerations is the brief outline of the revitalization of Polish cities in the period after World War II, while the conclusion deals with the fears and hopes related to revitalization activities that are presently initiated. The discussion takes into account the existing, critically assessed, legal regulations on revitalization.

The category of small towns is progressively polarized under the impact of metropolitan development. There is a growing diversification of such places with regard to functions performed and the overall position in settlement systems at regional and national levels. Aside from the division line which separates these towns that are located within, from those situated beyond the commuting range of large urban centres, this is increasingly related to local, territorial capital held. In general, however, the flattening of urban hierarchy and the decreasing importance of hierarchical linkages affect in particular the role of local service centres, especially in sparsely settled peripheral areas. Concerning the future, three alternative development paths are discussed in the article against the relevant conceptual background. These refer to the cyclical nature of urbanization processes, assume an extrapolation of trends observed or, alternatively, consider a containment of metropolization phenomena. With respect to policy related questions, changes in small town networks in peri-urban zones are identified as a specific, sensitive issue.

The article aims to explain whether in 2004–2015 Poland experienced economic convergence between regions and counties (Polish: powiat), and whether this process occurred within the regions (Polish: województwo). Following Poland’s EU accession, the Polish policy became dominated by the polarization and diffusion concept of regional development, which may cause differences in the short term, while in the long run it may contribute not only to the increased efficiency of public funds allocation, but also to the elimination of disparities in growth levels. In the analysed period Poland experienced a process of economic divergence between the regions, only the years 2006–2008 saw a short-term reduction in regional disparities. On the other hand, a slow process of reducing economic inequalities between counties took place after 2004. It was, however, varied – a clear reduction in disparities occurred between the land counties (Polish: powiat ziemski) in an almost monotonic manner, whereas city counties (Polish: miasto na prawach powiatu) did not undergo any convergence. Within the regions, the process of economic convergence varied: in five regions, β-convergence was identified, and σ-convergence occurred in all the regions. The process of reducing disparities was significantly dependent on the development pathway of the region.

The paper presents the indicator method as an important tool of research in social sciences with the focus on socio-economic geography. It introduces the notion of indicator in the methodological meaning and concentrates on its basic type, i.e. the inferential indicator. The concept of an indicator is explained using a realistic approach, which assumes that unobservable conceptual properties can be represented by observable real properties. In this approach, an indicator is characterised as an observable variable assumed to point to, or estimate, some other unobservable variable. The indicator method is then a way of the realistic conceptualization and a cognitive operation as well. The paper contains the systematization of cognitive indicators in socio-economic geography. It also shows the examples of the construction and interpretation of applied indicators.

The article aims at presenting the philosophy and model of the development vehicle to be understood as a new concept and tool to investigate and program local and regional development processes. The practical issues covered by the article include the identification and discovery of development vehicles, the elements of which can be observed in Polish metropolitan areas and agglomerations.

This paper presents a set of concepts aiming at the reconstruction of mechanisms of economic space development. These concepts are ordered in the way that consecutive concepts add new pieces of knowledge increasing the degree of cognition of the mechanisms of the economic space. This set includes among others: a shift from one steady-state to the next steady-states, self-organization and the development far from equilibrium, multiple equilibrium, punctuated equilibrium, innovation in the phase transition, a pulsative course of the development process, an emergence of complex spatial systems, a development code of the system of regions.

The paper presents a concept of application of the RTK-GPS technique to surveys of railway tracks. The concept was examined during an experimental survey performed over a 2 km long track section. The test survey confirmed functionality and sufficient accuracy of the RTK-GPS method as applied to railway track measurements aimed at track regulation.

The paper presents discusses a formula for the mean error m, of the refraction factor, determined basing on synchronie and bi-directional observations of vertical angles, performed for a section of trigonometric levelling. It turns out from analysis of the formula that the mean error of this factor is mostly influenced by mean errors of vertical angles and heights of distance meters and prisms over survey points. The error of a distance may be neglected; this leads to the simple working formula.

According to analyses of results of surveying measurements, description of undefined subsidence, performed with the use of S. Knothe's model is characterised by the sufficient coherence with results of measurements since the moment when the full subsiding trough becomes visible on the terrain surface. Lower coherence with results of measurements appears in the initial period after commencement of exploitation. In order to improve the quality of description within the initial phase of subsidence, a mathematical model has been developed, which is based on relations between the coefficient of the velocity of subsidence and the time co-ordinate, and from geometric co-ordinates. Obtained solutions have been verified basing on results of surveying measurements, with the use of a special computer software.

One of the basic processes in photogrammetry consists of identification and measurements of conjugate (homologous) points located within image overlapping. In analytical photogrammetry this process is solved manually by an observer. In digital photogrammetry this process is solved automatically by software and it is called image matching. This process has considerable importance for automation of orientation or aerial triangulation of photographs. The accuracy of image matching process influences the accuracy of determination of image orientation elements and computed point coordinates. This article presents the author's idea concerning matching of digital images with regard to correlation between neighbouring pixels. First, the problem of correlation between point co-ordinates will be examined in analytical photogrammetry, what will simplify considerations related to digital photo gram metry.

The problems of identification of objects have been strictly bound with sea navigation for a long time. The article presents a method of object identification by means of artificial neural networks. The classification of objects is effected on the basis of a radio signal. A comparison between classical methods and neural methods has been made. The results of research performed have been presented on real data, and a detailed analysis of the probabilistic network and its identification.

One of the major tasks in digital photogrammetry is image matching technique for finding corresponding points in a stereopair. Area-based matching has been acknowledged as being more precise than feature-based matching. Least squares multi-point matching (LSMM) is one of the Global Image Matching (GIM) which was developed from the Least-squares Single point matching (LSSM) so called area-based matching. LSMM method has been more reliable than LSSM one because the relationship between the different neighbouring points is considered in simultaneous computation. LSMM is just for the simultaneous determination of the horizontal parallaxes at the node points of the regular rectangular nets for the purpose of the establishing the DEM. This paper undertakes a trial of improving the accuracy of LSMM by consideration of the correlated pixels and terrain height differences.

Among methods of solving decision matters the technique of decision charts has been presented in this paper and the idea of their cartographic development has been proposed. The problem has been described on the base of real application that concern of choosing a place on water intake for new arisen housing estate. The technique of colour scale for visualization of choice criteria and logical operations on colour images has been proposed in order to find the place which meet earlier formulated conditions in the best way. The results has been colected in modified decision chart. Next possibilities of development of the method have been indicated

The experiment conducted with the NOKIA Multigraph 447Xpro presented in this article shows that a change of colour temperature results in a change of general colour appearance displayed on the CRT screen. However, it does not considerable affect chromatic coordinates of RGB monitor primary stimuli. The change of :a produced colour appearance which it causes can have a considerable influence on colour matching - at tłie stage of map designing on the screen. Discordances among given colour temperature set-up in lhe screen menu in relation to computed by means measurements of colour temperature are shown. Of computing and Methods of colour temperature calculating and setting are given. It has been stated which channel has a critical (decisive) influence on a colour temperature setup.

In the paper the formula for equation of the observation correction is introduced, which also includes observation terms, which are not the subjects of adjustment. The system of such type of correction equations is the basis for calculation of intermediary unknowns, which are not only the function of observations being the subjects of adjustment, but also of observations, which are not deformed by corrections. The paper presents proofs of formulae for calculation of mean errors of intermediary unknowns and functions of those unknowns for a considered case. An important general conclusion results from those proofs: both, the mean en-or of the ith unknown, and the mean error of the function of unknown, obtained from the discussed system of equations can not be smaller than the corresponding error obtained form a system, which does not include those observations. Presented formulae may be used in the case of adjustment of a connected network to higher order points, which co-ordinates are considered as observations, which are not the subjects of adjustment. Therefore we assume them as constant in a narrower range, i.e. we assume constancy of their values after adjustment; however their mean errors are considered in accuracy analysis. Derived formulae may be also used for calculation of mean errors of explicitly determinable geodetic constructions connected to known points, if the influence of mean errors of co-ordinates of those points on the mean error of a given function of unknowns is to be considered.

In this paper, the issues of today's maritime hydrography and its state are discussed. The substance of maritime hydrography and its state of development are presented. The maritime hydrography is shown and discussed from three different points of view: as the kind of maritime human activity and special maritime service; as the maritime profession and field of undergraduate and graduate education, and as the branch of science.

There is also presented the substance of the navigational and hydrographical provision of the ships' special tasks, as well as the development trends of this provision.

Previous research showed that children can exhibit preferences for social categories already at preschool age. One of the crucial factors in the development of children’s attitudes toward others is children’s observation and imitation of adults’ nonverbal messages. The aim of our study is to examine whether children’s tendency to perceive and follow nonverbally expressed attitudes toward other people is related to ingroup bias, i.e. the tendency to favor one’s own group over other groups. We examined 175 preschool children (age in months: 61–87; M = 72.6, SD = 6.53) presenting them with a video of a conversation between a message sender and a message recipient. The study was conducted in a minimal group paradigm. We found that children accurately identified the message sender’s attitude toward the recipient and also generalized this attitude to other members of the new group. We also found explicit ingroup bias among children from the message sender’s group. However, no generalization of the sender’s attitude to other ingroup members was found. The results are discussed in reference to previous findings on the role of imitation of adult’s non-verbal behavior for the development of social attitudes among children.

Since psychology emerged as an independent field of knowledge, there has been no consensus as to how it should develop, either, in the idiographic or nomothetic way. In the course of time, due to a commitment to what was seen as objectivity in science, the nomothetic approach came to dominate psychology. Thus, researchers used mostly quantitative psychometric methods to establish general rules of human behaviour. In doing so, the essence of nomothetic research is to be extremely careful when interpreting results not to make a reasoning mistake such as the ecological fallacy, as may happen when a researcher draws conclusions about nature of the individual in the group based on average results of the whole group. In the article, we presented two methods for longitudinal research designs which address this problem, and give more idiographic information about participants; via the Reliable Change Index and the Modified Brinley Plot. Finally, we provide a IBM SPSS Statistics syntax automatizing the whole process of computation for these new features.

Research suggests that placebo can reduce the misinformation effect. We aimed to examine for the first time whether placebo administered in the guise of caffeine can reduce the misinformation effect. One hundred and twenty -three healthy volunteers were randomly assigned to four groups in a 2 Placebo (Present, Not Present) × 2 Narrative (Misleading, Correct) study design. Participants from placebo groups drank 100 ml of placebo solution. They were told that it was water mixed with caffeine which could positively influence their memory. After three minutes, they watched a short movie clip as an original event and read a narrative with misleading details or correct details as a postevent information; they then completed a 22 -item, two -alternative forced -choice questionnaire. The results reveal that the misinformation effect occurred. Although participants in the placebo with misinformation group scored better than participants who did not drink placebo and read the narrative containing misleading details, the difference was not statistically significant. Thus, it is concluded that placebo might not be enough to reduce the misinformation effect when it is administered in the guise of caffeine.

According to the most popular conceptualization of materialism by Richins and Dawson it consists of three components: acquisition centrality, acquisition as the pursuit of happiness and possession -defined success. They are usually combined and an overall indicator of materialism is used commonly in various studies. In the article the three components are examined separately. Differences in their nature are revealed in a theoretical analysis, whereas in two empirical studies the ways they connect with well -being are presented. The results show that the overall materialism explains much less variance of well -being than the three components taken separately. Of the three the possession-defined happiness is the most detrimental to all aspects of well -being. The possession -defined success does not connect with well -being at all. Finally, acquisition centrality elevates hedonic and psychological well -being. The conclusion is that the modest effect of materialism on well -being, usually identified in various studies, is probably at least partly due to conflicting forces existing within the construct.
