Opis:
The purpose of this study is to identify how the sustainability and digital transition influence banks. The main thesis can be expressed as follows: sustainability transition and digital transition are changing the role and function of banks, especially the products and services offered by banks. Banks are one of main actors of a broader, multi-level governance designed to support the transition to smart, efficient and low carbon economy. The framework’s structure is based upon the multi-level perspective on socio-technical transitions created by F.W. Geels. The first section of this paper presents the most popular approaches to the problem at hand, as reported in professional literature. Section two presents characteristics of the various actors involved in the anticipated transformation of the economy. The third section discusses the changing roles and frameworks of banks associated with the notion of the broader concept of sustainability and digitalization.

Opis:
In the period 1950–2020, international migration in Europe changed significantly. One of the most characteristic features was the change in net migration from negative to positive. At the beginning of the twenty-first century, Poland belonged to the minority of countries in this respect – that is, it experienced strong emigration but only minor immigration. However, migration in Poland has also been changing. In the second decade of this century, the outflow of people has weakened, the inflow of migrants has increased and the migration balance has become positive. I analyse these phenomena from the theoretical perspective of the migration transition that was experienced in the second half of the twentieth century by most countries in Western, Northern and Southern Europe. I attempt to answer the question of whether the latest migration phenomena prove that this transition is also occurring in Poland. In conclusion, I argue that the available to-date evidence provides an affirmative answer to this question.

Opis:
Two major approaches have dominated the field of the sociology of development: theories of modernization, which focus on developed countries, and theories of development, which concentrate on Latin America, Africa, and East Asia. The social transformations in China, Russia, and the other European former socialist countries since 1989, however, have challenged both the traditional approaches of Sociology of Development with a series of new issues: how should one evaluate the various pathways to development in different countries and regions? how should one examine the state–society relationship in social development and transition? how can one deal with the social inequality in the process of development? These topics have expanded the scope of the Sociology of Development and provided an opportunity to construct new theories. I suggest that, in response to the practice conditions of ongoing socioeconomic transformation, new theories of transition, in addition to theories of modernization and theories of development, is the imperative need in the field of the sociology of development.

The paper deals with the problems of boundary layer modelling in turbomachinery applications, where various mechanisms are present, especially under the conditions of upstream wakes. The paper presents a review of recent achievements in interpretation of by-pass, wake induced and separation induced transition processes as well as the discussion of most important aspects of transition modelling. This review is complemented by physical explanation of transition phenomena based on the recent literature data as well as on the results of numerical and experimental investigations performed at the Institute of Thermal Machinery. The two test cases, i.e. steam turbine blade profile N3-60 and gas turbine blade profile T106A are used as a basis for the discussion of applicability of modern transition models.
Artykuł poświęcony jest zagadnieniom modelowania warstwy przyściennej w maszynach przepływowych, w których występują różne mechanizmy przejścia laminarnoturbulentnego, w tym obecne zwłaszcza w warunkach napływających śladów. W artykule przedstawiono przegląd najnowszych osiągnięć w interpretacji przejścia typu bypass, indukowanego śladem i oderwaniem warstwy przyściennej oraz przedyskutowano najważniejsze aspekty modelowania przejścia laminarno-turbulentnego. Przegląd ten został uzupełniony opisem fizykalnej interpretacji zjawiska przejścia w oparciu o najnowsze dane literaturowe, jak również w oparciu o własne wyniki badań eksperymentalnych i numerycznych prowadzonych w Instytucie Maszyn Cieplnych. Dla udokumentowania własności nowoczesnych modeli przejścia laminarno-turbulentnego wykorzystano dwa przypadki testowe, dotyczące profilu łopatkowego turbiny parowej N3-60 oraz profilu łopatkowego gazowej turbiny lotniczej T106A.

Opis:
The research paper presents institutional systems of economies in the following transforming countries: Poland, the Czech Republic, Hungary, Slovakia, Estonia, Lithuania, and Latvia. The article aims at indicating the changes which have taken place in informal institutions' structures since the early nineties. It also attempts to determine how informal institutions are supporting formal institutions. Heading towards building new institutional systems, transforming countries face a barrier of slowly evolving informal institutions. A mismatch between institutional structures can be noticed in transforming countries. Low level of trust in people, resistance to new ideas, strong attachment to traditional behavioural patterns and excessive role of “connections”, relatively low level of self-expression, high expec-tations towards the state and its welfare functions, and low social activity within the society, can be observed. The institutional changes in informal components have been presented using data from World Values Survey, CEPII and G.Hofstede research.

Opis:
Poland, traditionally a country of emigration, started to record a positive migration balance in recent years. However, thus far, no forecast has indicated the possibility of Poland’s transition from a net sending to a net receiving regime. This study indicates the theoretical underpinnings of such a change and provides an international migration projection. To this end, we refer to the historical experiences of other European countries, more advanced in terms of the Demographic Transition (DT), Second Demographic Transition (SDT) and Migration Transition. We develop a deterministic migration projection of four types of flow (the in- and out-migration of nationals and foreign citizens) up until 2060, combined with the United Nations’ Bayesian probabilistic models of fertility and mortality projections. The results show that Poland will evolve from having a net sending to having a net receiving status around 2030–2034. The combined effect of migration flows on population ageing will not be significant but, in the long run, when considered separately, the four types of flow will have non-negligible, though opposite, effects: the outflows will contribute to population rejuvenation, while the inflows will accelerate population ageing.

Opis:
The authors set out to determine if the convergence theory passes the test in 25 transition economies. On the basis of statistical data for the years 1991-2004, using an econometric model, they analyze the influence of GDP per employee on the growth of labor productivity. They also consider other factors with an influence on sustainable economic growth. Considering the significant heterogeneity of the analyzed economies in terms of market reforms and institutional conditions, the authors divided the sample into three relatively homogenous groups: 10 new European Union member states excluding Cyprus and Malta; 12 CIS countries; and five Southern and Eastern European economies. The authors evaluated conditional convergence in individual groups of economies, concluding that economies with lower GDP per employee at the start of transition were characterized by a higher rate of growth for most of the analyzed period. GDP per employee primarily depended on investment in physical and human capital, the share of government spending in GDP and inflation. Moreover, the analysis showed that convergence processes in individual countries led to converging long-term economic growth rates, which were positive rather than neutral, contrary to the classic convergence theory.

They are an indispensable element of human functioning even though the participation in them is not always fully conscious. Organized outside daily routine they signify the uniqueness and importance of events which they accompany. Despite the fact that they themselves undergo changes what should be noticed is the need of stability based on what is certain and predictable. Understanding rituals of individuals and groups is a necessary condition for understanding the present time.

By comparing results of the studies on journalists with expectations and attitudes of current Polish journalism students, the paper offers an insight into the ongoing changes that have been observed among Polish journalists in the last four decades. In particular, the review revealed signi# cant changes in a demographic profile of Polish journalists regarding gender, education, and employment, as well as their motivation to work in the profession. Furthermore, professional values of journalism in Poland have been slightly shifting from a traditional pro# le of a social educator and watchdog to new ones, such as a news provider.

Cambodia suffered dramatically from the Khmer Rouge regime in 1975 to 1979 as well as from Vietnam’s invasion and the following civil war till 1989. Both caused enormous destruction, not only of infrastructure, educational institutions, the financial and health system, but – even more importantly – to its human capital. After 1989 Cambodia’s economic transformation started but is insufficient until now. The conception of a market order – introduced by Walter Eucken (1952/90) - may be a helpful approach to improve the economic and social situation in the country. But before constitutive or regulative principles of a market order can be implemented in Cambodia successfully some basic political problems must be solved. They are defined already by North / Wallis / Weingast (2009) as rule of law for the elite, civil society, and consolidated control of the military. Additionally, there are further obstacles which must be drawn into consideration like cultural differences etc. It is the aim of this paper to describe the political and economic situation in Cambodia briefly. Then the necessary preconditions for sustainable development in the country will be introduced. Subsequently an economic policy in line with the market order conception will be recommended and further obstacles will be discussed, at least.

Theoretical models proposed in the literature for the deflagration-to- detonation transition (DDT) in cast explosives are evaluated for primary explosives (complex compounds) in this work. The one-dimensional model of burning (deflagration), consistent with the classical Chapman-Jouguet theory and a model of burning under the conditions of zero mass velocity behind the flame front are presented, and the physical phenomena accompanying the accelerating wave of flame in solid explosives are described. The results of calculations taken from the literature are presented for the cast high explosive (pentolite). The model of acceleration of the deflagration wave was used to estimate the time and distance at which the process of burning leads to the emergence of a shock wave in primary explosives. The influence of burning rate and the physical properties of an explosive on the distance of deflagration to detonation transition is analysed.

The process of transition of the CEE economies resulted in an increase in their innovativeness and internationalisation. The Polish economy as a transition one has been subject to these processes to a large extent. Due to the fact that innovativeness and internationalisation are perceived as related phenomena, a study of their changes and relationships between them in the transition process may bring interesting cognitive outcomes. The aim of the paper is to describe the changes in the level of innovativeness and internationalisation of the Polish economy when compared with other European economies from the transition process perspective.

Opis:
Research background: Entrepreneurship issues in the transition economies have attracted growing attention from scholars in recent years. However, the debate over the value of entrepreneurship in reinforcing structural change is still incomplete. The need for a more thorough approach is noticeable, taking into account drivers which determine entrepreneurial activity in the transition economies. The findings may be useful for recognising opportunities and threats of the development of these economies. Purpose of the article: This paper extends research on entrepreneurship in the transition economies by considering drivers of entrepreneurial activity. The aim of the paper is to investigate what drivers have their consequences for entrepreneurial activity in the Visegrad countries. As the Visegrad countries represent a unique context, because they faced a similar structure at the beginning of the transition process, a valuable insight can be gained by focusing on them. Methods: Hypothesis development is based on the literature review. Fixed effects panel regression was employed for hypothesis testing. Panel data consists of 440 observations for the Visegrad countries for the 2004-2014 period. To control for autocorrelation and heteroscedasticity, Durbin-Watson test and Wald statistic were used, respectively. Findings & Value added: This paper contributes to the existing literature by presenting an analysis of drivers having their impact on entrepreneurial activity in the Visegrad countries. It provides new insights on understanding of the entrepreneur-ship issues in the transition economies. The main finding is that entrepreneurial activity in the Visegrad countries is determined significantly by the economy structure and human capital. However, the significance and the intensity of these effects are different. The findings may be interesting for policymakers in particular. Shifting from general entrepreneurship support towards a focus on promoting entrepreneurial behaviour among high-skilled workers should be considered. Fostering networking, collaboration and internalisation should be regarded for knowledge transfer and spillover enhancement.

Opis:
Advancements in computer technology that have occurred in recent decades have enabled an intensive development in cartographic methods for direct representation of phenomena dynamics. Even with the appearance of ever more advanced technical solutions, the theoretical basis still needs supplementing. The previous cartographic literature emphasises the importance of congruence and isomorphism principles preservation that aims at increasing the effectiveness of dynamic displays. Nevertheless, it is frequently the case that discontinuous phenomena are depicted with the use of smooth transitions. For this reason, it is vital that experimental research should lead to defining which representation methods are appropriate for a given type of content. Our study was focused on the cartographic design of scene transitions in animated maps. Two main conclusions of the research indicate that 1) mode of transition influences the interpretation of the content of cartographic animation depicting discrete changes, 2) maps executed in a smooth mode demonstrate lower effectiveness when compared with animations using an abrupt and abrupt with decay effect transitions.

This paper presents the results of research of influence of degree and number of polynomial terms of railway transition curves (TCs) on their dynamical properties. The research performed for needs of this work are planned numeric tests. The search for the proper shape means the evaluation of the curve properties based on chosen dynamical quantity and generation of such shape with the use of mathematically understood optimisation methods. For the needs of this work advanced vehicle model, dynamical track-vehicle and vehicle-passenger interactions as well as optimisation methods were exploited. The subject of the analysis are odd degree polynomial transition curves of the 5th, 7th, 9th and 11th degree. For each degree of the polynomial a range of acceptable number of polynomial terms was determined. One dynamical quantity - minimum of integral of vehicle body lateral acceleration - being the results of simulation of railway vehicle advanced model is exploited in the determination of quality function (QF).

The text is an analysis of the Polish premiere of Tony Kushner's drama Angels in America. The drama, staged in 1995 as Angels of America at the Wybrzeże Theatre in Gdańsk, directed by Wojciech Nowak, has not made it into the history of Polish political theatre. However, the testimonies of its reception today allow for a complex analysis of the entanglement of political theatre in the so-called political transition. With the help of the category of “normality”, I am trying to expose the meandering paths of emancipation in the Polish theatre of the 1990s - the time of transition.

In this paper we investigate empirically the relationship between globalization and human development in post-transition countries using annual panel data for the 1971-2010 period. We show that there exists a positive and statistically significant relationship between globalization and human development in the case of unconditional regressions. This relationship remains positive and signifi-cant once the process of European and regional integration is controlled for. However, when differences in the level of economic development are taken into account the globalization variable loses its statistical significance.

Opis:
This paper is one of the first studies dedicated to the extensive examination of the dynamics of key sectors in Poland in the period of transition. The research was based on the maximum entropy decomposition of the Leontief inverse applied to the highly-disaggregated input-output tables covering the period of 2000–2005. The results allow formulating the list of sectors, which, more or less, have preserved the status of the key sectors in Poland. In turn, some sectors (especially the financial-intermediation- and food-and-agriculture-related ones) have significantly derailed, while services-related sectors (including the transport, tourism, and trade services) have clearly gained in importance. These facts, together with rising importance of certain manufacturing sectors, may suggest that Poland has largely managed to avoid the most negative consequences of the process of de-industrialization, which has been taking place in CEE from the beginning of transition.

Opis:
In the paper attention is focused on the necessity to systematize the procedure for determining the shape of transition curves used in vehicular roads and railway routes. There has been presented a universal method of identifying curvature in transition curves by using differential equations. Curvature equations for such known forms of transition curves as clothoid, quartic parabola, the Bloss curve, cosinusoid and sinusoid, have been worked out and by the use these equations it was possible to determine some appropriate Cartesian coordinates. In addition some approximate solutions obtained in consequence of making certain simplifying assumptions orientated mainly towards railway routes, have been provided. Notice has been taken of limitations occurring in the application of smooth transition curves in railway systems, which can be caused by very small values of the horizontal ordinates in the initial region. This problem has provided an inspiration for finding a new family of the so-called parametric transition curves, being more advantageous not only over the clothoid but also over cubic parabola as far as dynamics is concerned.

In the paper two approaches to the problem of estimation of transition probabilities are considered. The approach by McCullagh and Nelder [5], based on the independent model and the quasi-likelihood function, is compared with the approach based on the marginal model and the standard likelihood function. The estimates following from these two approaches are illustrated on a simple example which was used by McCullagh and Nelder.

Opis:
The paper uses survey data to analyse the financing conditions of firms in transition countries. The results show that small firms have considerably more problems with access to and cost of finance than larger firms. Small firms also display markedly different financing patterns than large firms, relying to a much greater extent on internal financing sources and less on bank credit or other sources of formal finance than large firms. To examine the determinants of access to and cost of finance the survey data are combined with macro and financial variables in an ordered logit model. The results indicate that a heavy reliance on foreign and state-owned banks has adverse effects on the average firm’s financing condition.

Opis:
Circular economy offers new visions of how diversely urban spaces could be inhabited and managed. While the generation and management of waste is being treated through innovative practices, disused industrial, rural, and infrastructural areas are resistant to becoming included in a closed-loop cycle. They, in fact, establish wastelands that need to be completely re-imagined as a precondition for the transition. The fact of shifting the definition of a ’neglected area’ into a ‘wasteland’, in line with the metaphor of urban metabolism, could be of tactical importance for generating alternative policies and practices. In exploring how the transition impacts Naples’ urban region, the paper argues that turning wastelands into resources has the double potential of rehabilitating spaces and challenging the governance model in use, overcoming barriers in multiple sectors.

The results show how important it is to meet the emotional needs of the child, especially the need to maintain a secure and stable relationship with both parents in a situation of experiencing one parent’s transition and separation of parents (divorce). The results are presented and interpreted in the light of the attachment theory of John Bowlby and the concept of the five emotional needs derived from the theoretical basis of schema therapy.

Opis:
Social capital is widely seen as an important factor behind economic development. It facilitates ties between businesses and reduces transaction costs. It also creates an innovation-friendly environment. But research reports also list some negative aspects of social capital, such as the creation of divisions within society and the uncontrolled emergence of various self-interest groups, and, in extreme cases, mafia-type organizations. Another problem is that the very concept of social capital has not been clearly defined in research reports, according to the author. Lissowska sets out to determine if post-socialist countries differ from other economies in the way they use social capital. She starts out by defining social capital as a partially altruistic approach of an individual toward other people. The study is based on data for 23 European countries collected during a European Social Survey in 2006. This body of data makes the author conclude that post-socialist countries have distinct features as far as social capital is concerned, such as a low level of social confidence and a tendency to maintain “close” rather than “remote” social ties. However, other countries such as Portugal, Cyprus and, less markedly, Spain, display similar features, Lissowska notes. These features may result from these countries’ totalitarian past when social ties were more difficult to establish and maintain than today. They also stem from historic cultural factors such as insufficiently developed civil-society traditions in some of these countries, poor quality of government and law enforcement, religious traditions and new social trends such as people’s drive to succeed economically.

Opis:
The present paper aims at analysing the trajectories of the Romanian intellectuals immediately after the Revolution in 1989, and the fall of Communism. During the Communist years, the term itself (intellectual) had been used with ideological connotations. The intellectual (as a social value) was discussed according to the Marxist ideology, taking into consideration his concrete usefulness and his contribution to the Communist society. Immediately after 1989, the fundamental dilemma faced by the Romanian intellectual represents the necessity of the implication of the intellectuals inside the society or, on the contrary, the isolation in an Ivory Tower of creation. The second challenge aimed at the necessity of synchronizing the Romanian elite with the European one; the topics for debate in Western and Eastern Europe during the Cold War were fundamentally different. The purpose of this paper is to analyse the influence and the commitment of the Romanian intellectuals in reshaping the Post-Communist Romanian society.

Policies that are introduced to mitigate adverse consequences of climate change involve economic costs. For some households, these costs will materialise in the form of an increase in prices of consumption goods, whereas for others they will materialise in the form of falling productivity and wages. Disentangling these two effects is important in the light of the design of funds that aim to support the households that are negatively affected by climate policy. In this article, we study the effect of carbon tax on welfare through changes of consumer prices and wages in a general equilibrium setting. In the first step, we review the literature on ‘top-down’ models, which are used to evaluate the macroeconomic cost of climate policy. We find that these models usually do not account for loss of productivity of workers who must change their sector due to climate policy. In the second step, we develop a theoretical, micro-founded, two-sector model that explicitly accounts for the loss of productivity of workers. The compensation of climate-change mitigation costs would require allocation of separate funds for the affected consumers and workers.

Opis:
This special section opens a two-part collection of articles, to be published in two consecutive issues of CEEMR in 2019, looking at various aspects of migration from and into CEE that address the links between mobility and political and economic transition in the region. Its goal is to discuss, on the one hand, the contribution of the migration research conducted in CEE to the broader migration literature and, on the other, to demonstrate region-specific topics. An important inspiration for the preparation of this issue is the 25th anniversary of the Centre of Migration Research (CMR) at the University of Warsaw; this is accompanied by some reflections on how migration studies have developed in Poland and other CEE countries during these years of transition. Since the very beginning, the idea that guided research conducted in the CMR was to analyse migration in a broad socio-economic context and to develop cooperation with the best international teams of migration scholars. Therefore, for this special collection, we invited contributions which demonstrate the development of scientific collaboration between CMR researchers and outstanding European and non-European scholars, as well as articles by international researchers from all over Europe which focus on specific migration topics intersecting with post-communist transition in the CEE region.

Proces demokratyzacji w Gruzji ma swoje trudności, głównie związane z aspektem kulturowym i społeczno-ekonomicznym. Wyzwania polityczne są powiązane z postawą społeczną i odwrotnie. Historyczna rola kościoła prawosławnego w zachowaniu gruzińskiej tożsamości narodowej przez wieki jest nadmiernie kompensowana z częstymi pisarskimi uwikłaniami w życiu publicznym. Niedemokratyczne rządy dokonały wszelkich starań, aby sfinalizować proces transformacji i przez dwie dekady stan pozostawał w szarej strefie między konsolidacją i autokracją. Rok 2012 został oznaczony rokiem dla nowych nadziei demokracji Gruzji. Nowy rząd został wybrany przez wolnych i uczciwych wyborców, ale demokracja wymaga warunków aby przetrwać i ten artykuł je bada.
Abstract: The process of democratisation in Georgia has its obstacles, mostly connected with cultural and socio-economic aspects. Political challenges are interlinked with societal attitudes and vice versa. The historical role of the Orthodox Church in preserving Georgian national identity throughout the centuries is over-compensated for, with frequent clerical involvements in public life. Non-democratic governments have made no effort to finalise the process of transition and for two decades the state has remained in the grey zone between consolidation and autocracy. 2012 was marked as a year for the new hopes of Georgian democracy, a new government was elected via free and fair elections, but democracy needs conditions to endure and this paper examines those conditions.

Opis:
The article is a summary of previous work on the possibility of using Petri layers in adaptive neuro-fuzzy controllers. In the first part of the paper the controller and two types of Petri layer have been presented, competitive layer which resets certain signals and transition layer which causes omission of signals. Layer properties were described and comparison has been made. In the second part of the paper, the results of a simulation showing the advantages and disadvantages of proposed solutions have been presented. Both quality of reference signal tracking and energetic cost of control process have been calculated. In the last part, analysis and comments on the results were made. Main conclusions are that transition Petri layer can significantly reduce growth of numerical cost of the algorithm despite the increase of fuzzy rules count. Also both competitive Petri layer and transition Petri layer by changing some inner signals can affect output value of the fuzzy system and thus the control quality indicators change. Most positive solutions have been pointed out

General transition curves employ only one curvature extremum, and the whole curved transition between two extreme points of zero curvature value is described by a single equation. As a result, the curves are very useful for the creation of route geometry in accordance with the principles of polynomial alignment. The paper describes the main concept of polynomial alignment and presents equations of curves which can be used in the proposed alignment procedure. In addition, the paper gives a detailed description of design procedures.

The purpose of this paper is to present the evolution of energy and climate policy (globally, in Europe, and in Poland) and review the tools which Poland could use to transform its economy towards a low carbon one. The author argues that energy and climate policy have become an economic policy that calls for a change in the socio economic model. As a consequence, this low carbon transition brings a change in the current model of state and society. The author supports this thesis by presenting global trends in energy and climate policies, explaining the dynamics of the EU policies related to emissions reductions, and outlining the current dilemmas of the modernisation of Poland. The paper concludes by presenting a set of tools that could be used for low carbon transition in Poland.

Opis:
In this paper some issues of the transition process from air- to oxy-combustion were investigated. Advantages of flexible combustion were described. Flexible combustion tests carried out at four European plants and five plants outside Europe of different scales of process and test parameters were presented. An analysis of the transition time from air to oxy-combustion of different laboratory and pilot scale processes was carried out. The “first-order + dead time” approach was used as a model to describe transition process. Transitional periods between combustion modes and characteristic parameters of the process were determined. The transition time depends not only on the facility’s capacity but also it is impacted by specific operational parameters.

Opis:
Demographic transition processes in Ukraine following the country gaining independence correspond neither to the demographic transition model nor the second demographic transition model. Unsuccessful political, social and economic reforms at the time in Ukraine and pressure exerted by Russia are deemed to be the cause of the situation. This means that demographic transition in Ukraine (both in terms of mortality and births) is far more detrimental than the premises of both models.

Opis:
We propose a theory of transition radiation emitted by charged particles entering a rough interface between two media. We show that the radiation process is influenced by surface inhomogeneities distributed both longitudinally and transversally with respect to the direction of particle motion. Moreover, we investigate in detail the transition radiation emitted at normal incidence of particles on a surface with Gaussian distribution of inhomogeneity deviations in relation to the smooth surface.

Państwa Europy Wschodniej (Armenia, Azerbejdżan, Białoruś, Gruzja, Mołdawia, Rosja i Ukraina) w procesie swojej gospodarczej transformacji otrzymują wsparcie finansowe i techniczne między innymi ze strony Europejskiego Banku Odbudowy i Rozwoju. W artykule przedstawiono wartość udzielonego wsparcia od początku działania Banku (1991) dla całego regionu i poszczególnych państw, a także ocenę współfinansowanych przez Bank projektów pod względem tzw. transition impact. Europa Wschodnia pozostaje liderem, jeżeli chodzi o wielkość otrzymanej pomocy finansowej, ale nie przekłada się to na ocenę zaawansowania procesu transformacji: tylko dwa państwa regionu (Rosja i Ukraina) mają status średniozaawansowanych, a pozostałe wciąż zaliczane są do gospodarek słabozaawansowanych w procesie transformacji.
Eastern European countries (Armenia, Azerbaijan, Belarus, Georgia, Moldova, Russia and Ukraine) receive financial and technical support among others from the European Bank for Reconstruction and Development in the process of its economic transformation. The article presents the value of support granted since 1991 for the whole region and individual countries, as well as the assessment of the projects co-financed by the Bank in terms of the „transition impact”. Eastern Europe remains the leader in terms of the amount of financial assistance received, but this does not reflect into a assessment of the progress of the transformation process: only two states in the region (Russia and Ukraine) have intermediate status and the remaining are still classified as early transition countries.

Opis:
This article analyses long-term changes in the persistence of low wages in Poland, given the variations in the general economic situation. All analyses are based on data from the Polish Panel Survey (POLPAN) conducted throughout the post-communist transition period, 1988–2013, on a representative sample of the Polish adult population. The study found that being in a low paid job raises the probability of experiencing the same situation five years later, even when controlling for the general economic context and the respondents’ demographic and economic characteristics. Upward mobility rates among initially low paid workers were significantly higher during periods of economic prosperity; however, even then low pay persistence remained substantial. The results also point to a secular growth in the persistence of poverty-level wages over the past two decades. Persistent low wages may bring about spaces of long-term poverty and social exclusion which cannot be overlooked by policy makers.

Opis:
This work presents studies concerning the relationship between reduction of glass transition temperature Trg and the glass-forming ability of FeCoB-based alloys. On the basis of theoretical considerations, Turnbull [1] determined the reduced glass transition temperature (Tg/Tl) as being 2/3 of the Vogel–Fulcher–Tammann (VFT) temperature; since then, continuous research has been carried out, aiming to calculate the Trg parameter and describe its relationship with glass-forming ability. In the majority of research papers, the reduced glass transition temperature is calculated from the relationship Tg/Tm, proposed by Uhlmann and Davies [2, 3]. On the basis of differential scanning calorimetry (DSC) studies, undertaken in this current work, the values of the following temperatures have been found: Tg, Tx, Tm and Tl, in addition to the temperature ranges: ΔTx, ΔTm and ΔTl. The correlation between: Tg/Tm, Tg/Tl and the glass-forming ability also has been discussed. Finally, for the investigated alloys, it has been found that the relationship proposed by Turnbull is reliable over a wide range of ΔTm.

Opis:
The article offers a new perspective on contemporary and past migration processes in the post-Soviet area by testing the usefulness of the concept of a migration cycle for the Russian case. By adopting the longue durée approach, we attempt to assess the advancement of Russia’s migration cycle, arguing at the same time that it constitutes an interesting, yet not an obvious case with which to test the utility of the concept. We postulate that, in tracking Russia’s migration trajectories in pre-1991 times, it is important to account for both the flows between Russia as the-then state entity (i.e. the Tsarist Empire, later the Soviet Union) and foreign countries and the flows between Russia as the core of the empire and its eastern and southern peripheries. Our analyses show that while – taking into account statistical considerations – Russia has undoubtedly already undergone the migration transition, it has not yet reached the stage of a mature immigration country. We also contend that migration transition for Russia occurred internally – within the-then state borders – and revealed itself with its transformation from a Soviet republic into a federative state

Opis:
Transition curves are an integral part of a route. They connect a straight section with a circular curve or two circular curves with different radii. Due to the forced path, the size and stiffness of the rail vehicle, their correct design is particularly important when constructing rail roads. Basing on the limits of lateral acceleration increment, non-equilibrium centripetal acceleration and wheel lift velocity, set in accordance with the model of motion of a material point moving along a trajectory determined by the track axis, the initial parameters of the considered transition curves were selected: radius of the curve, design speed of the train, length of the transition curve and track cant. The scope of research covered basic dynamic parameters: curvature and its increment, speed and acceleration of wheel lift, track twist and lateral acceleration increment. As a result of conducted analysis it can be stated that polynomial curves deserve special attention in the design of railway routes. By appropriate modification of their equation, it is possible to change easily positions of extremes of particular dynamic parameters and thus to adjust their values to terrain conditions, direction of movement and type of rail vehicle.

Procrastination as putting off until tomorrow what one had intended to do today is well-known tendency in everyday life. In an attempt to understand the character of procrastination in different life-domains, a large body of research has been accumulated over the last decades. This article was aimed to evaluate a specific decisional procrastination of school-to-work transition (SWT) that is treated as maturity postponement. Two studies are reported examining SWT procrastination defined as career indecision among Polish students graduating universities. In Study 1 (N=366), attitudinal and identity statuses were analyzed as correlates of career procrastination. A path analysis conducted for the model, which was aimed to explain the influence of career self-efficacy and occupational commitment on career indecision (dependent variable), revealed its very good fitness (RMSEA=.000). Those two independent variables explain 10% of career indecision variance. Stepwise multiple regression analyses conducted to ascertain relationship of five identity statuses (Brzezińska, Piotrowski, 2010) to procrastination measure (career indecision) showed that Commitment Making and Ruminative Exploration are strongest predictor variables. In study 2 (N=157), the stepwise multiple regression analyses conducted to ascertain the independent relationship of each of Big Five personality factor revealed that Neuroticism and Extraversion accounts of the most of explained variance of school-to-work transition procrastination.

However, the testimonies of its reception today allow for a complex analysis of the entanglement of political theatre in the so-called political transition. With the help of the category of 'normality', I am trying to expose the meandering paths of emancipation in the Polish theatre of the 1990s - the time of transition.

The green transition unfolding on a global scale is much less studied at the regional level, although its outcomes and management are strongly place-specific. This article presents a comparative study of green transition strategies in the Silesian Voivodeship (Poland) and the Khanty-Mansiysk Autonomous Okrug (KMAO) – Ugra (Russia), based on a qualitative content analysis of regional legislation and strategies. The regions share common specialisation in fossil fuel mining and have inherited some features of post-socialist economies. Research shows three common features of green transition policies in the studied regions. Firstly, much attention is paid to the dissemination of information about green transition and its benefits. Secondly, research on various green subjects and educational programmes for green market requirements are developed. Thirdly, it is planned for renewables to have a larger proportion in regional energy mixes. By mid-century, both regions are expected to reach climate neutrality, although by using different paths of development. Coal mines are planned to be closed down in the Silesian Voivodeship by 2050, while the KMAO – Ugra will retain its oil-mining specialisation but diversify it with hydrogen production.

Among the metals, Cu2+ exhibited maximal stimulatory effect on basal respiration and minimal inhibitory action on DNP-uncoupled respiration whilst Cd2+ promoted the strongest depression of uncoupled respiration and the largest swelling in NH4NO3 medium. Dithiothreitol induced a basal respiration release if added after high [Cd2+] and [Hg2+], and the stimulation was CsA-insensitive.

Each metal complex was synthesized by the reaction of new pyrazolochalcone derivatives with the metal salts such as Co(CH3COO)2·6H2O, Ni(CH3COO)2·6H2O, and Cu(CH3COO)2·2H2O. For the structure elucidation of ligand molecule various spectroscopic techniques such as 1H NMR, IR and mass has been used. The synthesized metal complexes were subjected to thermal study i.e., TGA and DTA in order to check structural conformation of synthesized metal complexes.

Opis:
Adaptation is the process of adjustment of an individual organism to environmental conditions while integration is the process of opening a group, community, place or organization to all members, regardless of race, religion gender or social class. The dynamics of the process of transition of Igbomina people from rural to urban society was gradual and spread over a long time. They initially established in town the socio-political institutions and behavioral patterns which were familiar to them to fulfill most of the needs, which they met in urban environment. Even in later migration, there were not many changes to the pattern of family life. Migrants retained their rural system of traditional values; the concept of the urban culture did not develop due to the well-established culture of circular migration. The range of relationships that ethnic groups maintained among one another within the frame work of contemporary migratory phenomena includes cases such as assimilation, pacific coexistence and animosity. It must be underlined however, that in spite of the integration process, the identity of Igbomina was not obliterated. The transition process of Igbomina into Lagos urban society could therefore be best described as acculturation rather than assimilation in that Igbomina culture in Lagos cannot be described as an extension of the northern Yoruba sub-culture from where they came to Lagos, it was rather a symbiotic relationship between the Yoruba, Hausa, Ibo etc. living together as neighbours.

Opis:
Palynological analysis of core Butovka obtained from the Protva River basin 80 km south-west of Moscow (55 stopni10'N, 36 stopni 25'E) provides a record of vegetation and climate change in the central Russian Plain spanning the Last Interglacial and the beginning of the following glacial epoch. Pollen profiles of the Mikulino (Eemian) Interglaciation in the Central Russian Plain show a distinctive pattern of the vegetation changes, reflecting an increase in temperatures towards the optimum phase of the interglaciation followed by a gradual cooling. Rapid climatic deterioration, manifesting an onset of the Valdai (Weichselian) Glaciation, took place after a slower cooling accompanied by increasing humidity of climate during the post-optimum part of the Mikulino Interglaciation. The interglacial/glacial transition had a complex structure, being marked by a sequence of secondary climatic oscillations of varying magnitude. A decreasing role of mesophilic plants and an increase in abundance and diversity of the xerophytes and plants growing at present in the regions with highly continental climate in the Butovka pollen record suggests that during the Early Valdai the climate grew both more continental and arid. With this tendency at the background, two intervals of climatic amelioration can be distinguished. Both of them are marked by the development of the open forest communities similar to the contemporary northern taiga of West Siberia. The latter of the two warm intervals had a larger magnitude of temperature changes than the first one, as indicated by a greater landscape role of dark-coniferous trees (Picea + Abies + Pinus sibirica). Based on its stratigraphic position and inferred features of climate and vegetation, the latter of the two warm intervals identified in the Butovka pollen profile can be correlated with the Upper Volga Interstade in the Russian Plain, or the Brőrup Interstade in West Europe. We can also tentatively correlate it with warm DO event 23 as reflected in the oxygen isotope record from the Northern Greenland deep ice-core (North GRIP Members, 2004). A slighter and shorter warming within the first cold stage of the Early Valdai probably had an interphasial rank and corresponded to a shorter DO event 24 in the NorthGRIP oxygen-isotope curve.

Opis:
The cognitive aspects like perception, problem-solving, thinking, task performance, etc., are immensely influenced by emotions making it necessary to study emotions. The best state of emotion is the positive unexcited state, also known as the HighValence LowArousal (HVLA) state of the emotion. The psychologists endeavour to bring the subjects from a negatively excited state of emotion (Low Valence High Arousal state) to a positive unexcited state of emotion (High Valence Low Arousal state). In the first part of this study, a four-class subject independent emotion classifier was developed with an SVM polynomial classifier using average Event Related Potential (ERP) and differential average ERP attributes. The visually evoked Electroencephalogram (EEG) signals were acquired from 24 subjects. The four-class classification accuracy was 83% using average ERP attributes and 77% using differential average ERP attributes. In the second part of the study, the meditative intervention was applied to 20 subjects who declared themselves negatively excited (in Low Valence High Arousal state of emotion). The EEG signals were acquired before and after the meditative intervention. The four-class subject independent emotion classifier developed in Study 1 correctly classified these 20 subjects to be in a negatively excited state of emotion. After the intervention, 16 subjects self-assessed themselves to be in a positive unexcited (HVLA) state of emotion (which shows the intervention accuracy of 80%). Testing a four-class subject independent emotion classifier on the EEG data acquired after the meditative intervention validated 13 of 16 subjects in a positive unexcited state, yielding an accuracy of 81.3%.

Opis:
This study examines the causal links between improvements in economic freedom and changes in GDP per capita of new EU members in transition in the period 2000-2009. The empirical results suggest significant causality running from changes in monetary and fiscal freedom, trade openness, regulation of credit, labour, and business, legal structure and security of property rights, and access to sound money to movements in GDP per capita, especially in less and moderately developed CEE transition countries. Moreover, we find evidence that improvements in economic freedom are one of the main factors stimulating the convergence of these economies towards rich EU members. The evidence of causality in the opposite direction is much weaker.

This paper examines the role of export diversification for economic growth in CEE transition economies. The results prove that before the outbreak of 2008 financial crisis export specialization rather than diversification was an important growth factor, especially in those countries which followed more specialized export patterns. However, after the outbreak of the crisis the direction of this causal link changed essentially. All three main aspects of export diversification turned out to play a significant role in reducing the growth slowdown effects of the 2008 financial crisis.

Opis:
This study seeks to understand what is the role of international migration in double transition: university-to-work-abroad and adulthood. The article assumes that schoolto- work transition is not a single event, but a phase of the life cycle. There is a time of looking for ones’ own career and life path. Migration is connected with the phase of growing up, the phase of maturing and cutting the umbilical cord with the parental home. This case study is about young Polish university graduates who took their first job(s) abroad and therefore transited somehow to adulthood. It was found out that this process where migration is involved is not flat and linear and is composed of four components (1) capitalizing in a foreign environment accumulated, up to migration, non-material resources; (2) crossing own mental borders; (3) building up relations with ‘other’ others; (4) building up labour market autonomy. This study utilises data from the first wave of qualitative longitudinal study (QLS). Thirty in-depth interviews were conducted with Polish university graduates age between 25 and 34.
Artykuł ma na celu odpowiedź na pytanie, jaka jest rola migracji międzynarodowych w podwójnym przejściu: z edukacji do pracy za granicą oraz w dorosłość. Przejście z edukacji do pracy jest traktowane nie jako jednorazowe zdarzenie, ale faza cyklu. Jest to czas poszukiwania własnej ścieżki kariery i miejsca na rynku pracy. Doświadczenie migracji w młodym wieku wiąże się z koniecznością dojrzewania, wyrywaniem korzeni i odcięciem pępowiny. Opracowanie dotyczy młodych polskich absolwentów szkół wyższych, którzy podjęli swoje pierwsze aktywności na zagranicznym rynku pracy, co wiązało się z wchodzeniem w dorosłość w obcym kontekście społecznym. Proces wchodzenia w dorosłość poprzez podjęcie pierwszych aktywności zawodowych za granicą jest złożony z czterech etapów: (1) kapitalizacją wszystkich zgromadzonych wcześniej (na migracji i przed) zasobów niematerialnych, (2) przekraczaniu własnych granic mentalnych; (3) tworzeniu relacji z innymi; (4) tworzeniu autonomii rynku pracy. Przedstawione analizy wykorzystują dane z I fali jakościowego badania podłużnego (Qualitative Longitudinal Study), w ramach której przeprowadzono 30 wywiadów pogłębionych z osobami pomiędzy 25 a 34 rokiem życia.

Opis:
This article deals with the turbulent transition phenomenon modelling and its influence on heat transfer. The purpose of the analyses was to verify the transition modelling implemented in the ANSYS CFX 11 commercial code for popular test cases (low flow speed) described in literature, and then use it for verification of the in-house CFD code (created for compressible flows). The inhouse CFD code has been extended lately for the Conjugate Heat Transfer modelling (CHT) as well, taking into account important flow effects, especially the turbulent transition. A Wilcox k-omega turbulence model with the Low-Reynolds modification was used in the in-house code. The calculations in ANSYS CFX were made using an SST turbulence model and a gamma-theta transition model. A fully turbulent flow was modelled by means of both codes, and the results were compared with the available experimental data. Then, the turbulent transition for several test cases was analysed with ANSYS CFX. Afterwards, the in-house CFD code was verified by means of ANSYS CFX for a higher flow speed (Mach numbers). The CHT modelling was analysed by means of both codes and the results were compared and discussed. The conducted analyses show that the results obtained by means of both codes are comparable, but the turbulence model used in the in-house CFD code is simpler and requires less computation time. A modification of two equations turbulence models can be an alternative for design problems in more developed laminar/turbulent flows.

Opis:
The focus of this study is electoral accounting practices employed by mayors in municipalities in a selected, exemplary region in a post-socialist country - the Lodz region in Central Poland. The goal is to identify characteristics of pork-barrel mayors responsible for municipal investment expenditures: their terms of ofice, partisan afiliation, and gender. The generalised method of moments was applied to estimate the impact that the electoral accounting practices of mayors had on municipal investment expenditures. All 177 municipalities in the Lodz region were investigated, from 2003 until 2019. Contrary to expectations, it was found that electoral accounting was practised by next-term and independent mayors rather than first-term or party-afiliated ones.

Opis:
The article discusses the transformation process and state’s economic role in the transition period. The article also deals with the main objectives and goals of state regulations, the peculiarities of countries’ socio-economic formation and procedures of institutional transformation. A government’s role in economic development is changing during the transition period. The main important issues that must be set are strictly centralised state regulations and forms that are completely new systems in economic management, which should be achieved through the elimination of a state’s domination over the economic system, strengthening a privatisation process and so on. It is true that the government’s dominating power should be eliminated but establishing a new marketing-institutional environment and market culture should be developed only under the state’s active legislative, coordinative and stimulating control. The theoretical basis of the article represents the researches of foreign scientists, economists and international organisation. The methodological basis of the article is based on economic analysis, comparison, and grouping methods. While preparing the article, modern experimental methods and model of macro-economic researches, as well as researches and statistical data, approaches and methodology of several international organisations were widely used.

It aims to sketch an interpretation of the Polish political transformation from the perspective of Karl Polanyi’s theory, particularly his concept of double movement. According to the proposed reading, the anti-liberal turn initiated by the electoral victory of the Law and Justice party in 2015 is a response to the commodification of labour, land and money as a result of neoliberal economic reforms.

Opis:
Study focuses on the issue of social change, based on transition process in Poland, analysed through gender perspective. Although many books and reports on both transition and women’s social position have been conducted and published before, studies joining those two perspectives were rare. The analysis bases on contemporary sociological theories of social change, concerning gender: Manuel Castells’s idea of the end of patriarchy, Ronald Inglehart and Pippa Norris concept of rising tide of gender equality and cultural change, theory of new gender contract formulated by Małgorzata Fuszara and Anthony Giddens’s idea of democratisation in private sphere. The book includes also wide account on history of gender issues in sociological theories and its contemporary position in mainstream social science. It also presents main theoretical approaches to social phenomena of gender inequality, and summarises key issues of research.

Transition metal (silver and copper) salts of the 5-nitrotetrazolate (NT) anion (1 and 2) have been synthesized and characterized by analytical and spectroscopic methods. Standard BAM tests revealed extremely high sensitivity values for these compounds. The combination with the ethylenediamine ligand in salts 3 and 4 decreases the sensitivities in comparison to salts 1 and 2 making for much less hazardous handling and rendering the synthesis of NT salts more accessible for up-scaling. Additionally, a copper ammonia adduct of the NT anion (5) was synthesized, which shows the particularity of being able to be initiated by a laser beam, thus, decreasing the risk of accidental initiation, which often accompanies the use of primary explosives.

Opis:
In this paper, we report the complex crystallization kinetics of phase transition happening in Ti-Cu-based bulk metallic glasses (BMGs), which play significant roles in the glass formation with respect to their low reduced glass transition temperatures, Trg. The first exothermic event just occurs when annealing the BMG samples in the supercooled liquid region, leading to the Avrami exponent deviating from conventional modes affected by the residual amorphous phase. For Ti43Cu43Ni7Zr7 BMG, the plasticity can be improved by pre-annealing at a sub-Tg temperature of 623K (≈50K below Tg) for 0.5 hour, however, deteriorated by 1 hour annealing, which could be related to the change in stability of this BMG against crystallization with different pre-annealing times.

Opis:
Commercial fishers in Poland demonstrate a unique version of “transition fatigue” (Rovelli, Zaiceva 2009). The situation leading to this phenomenon is related to three changes that occurred during the twentieth century. First, communist rule was marked by an orchestrated process of industrialization and a shift toward state-controlled fisheries after WWII. Second, political and organizational changes during the transition from a socialist to a free market economy in the nineties weakened social support and welfare structures in place during communism (and failed to replace them with something else). Third, accession to the European Union in May of 2004 introduced a new fisheries management strategy to the Polish fishing industry and the communities on the Baltic Sea coast. A regulatory vacuum created during the nineties has had negative effects on contemporary management strategies. EU-wide goals to reduce overcapacity since 2004 have significantly altered the composition of the Polish Baltic Sea fleet, while it is unclear that decommissioning schemes in Poland have had the positive results intended (Kuzebski, Marciniak 2009). A fishing closure and subsequent protests throughout the cod fleet in 2006 and 2007 underlined persistent problems in the management of Atlantic cod (Gadus morhua). In light of a potential shift to transferrable fishing concessions in the cod fleet, policy-makers should account for “transition fatigue” during the implementation process.

Opis:
From the time of its introduction, the concept of ‘transition’ has effected a tectonic shift in our understanding of post-socialism. In the process which has taken place during the last couple of decades after the collapse of East European socialist regimes, it has become transformed from one of the signifiers of the political and social change which occurred into a cornerstone for thinking, analyzing and predicting the future of post-socialism. Furthermore, in this article it is posited that all the political and social processes occurring in the ex-socialist countries are defined in relation to transition as an all-encompassing form of post-socialist experience. Relying on the discursive theory of Ernesto Laclau, this article attempts to consider together the usually separated questions of epistemology and ontology, and to ask what is the connection between scientific origins of the concept of transition and its political legitimacy. We claim that transition is a “sutured“ structure composed of various social experiences and political strategies, which naturalizes and universalizes the contingent power struggles that are taking place and will take place in the future of post-socialist countries. Therefore, severing the existing bonds between transition and the actually existing post-socialism is a necessary precondition for creating a more complex and productive understanding of the societies of East and South East Europe.

Opis:
W roku 1989 polska poligrafia przestała być branżą koncesjonowaną. Minione dwudziestopięciolecie było dla sektora poligrafi cznego okresem przebudowy struktury i modernizacji technologicznej. W okres transformacji polskie przedsiębiorstwa w stosunku do krajów europejskich wchodziły z olbrzymią luką technologiczną. Źródłem realizowanych inwestycji było najczęściej kupno nowej technologii zmaterializowanej w maszynach i urządzeniach produkcyjnych. Takie inwestycje stwarzały tylko chwilową przewagę konkurencyjną na lokalnym rynku – w rzeczywistości były bowiem obecne na rynku europejskim już kilkanaście lat, a rosnące wymagania odbiorcy w stosunku do jakości usług poligrafi cznych szybko udowodniły ich znikomą wartość. Ponadto zakup urządzeń z rynku wtórnego poza Polską w rzeczywistości budował przewagę konkurencyjną jedynie w środowisku lokalnym, bowiem w kraju pochodzenia już zastępowano je nowymi technologiami o lepszych parametrach.
In 1989 the Polish printing industry ceased to require industrial licensing. The last quarter of a century was a period of reconstruction of the printing industry structure and technological modernization. In the period of transition, Polish enterprises entered with a huge technological gap in relation to European countries. The source of the realized investments was most frequently the purchase new technology materialized in machinery and manufacturing equipment. Such investments created only a temporary competitive advantage in the local market. In fact, they had been present on the European market for over a decade, and increasing demands of the market in comparison to the quality of printing services quickly proved their insignifi cant value. Furthermore, the purchase of equipment from the secondary market outside of Poland actually built a competitive advantage only on the local market, as in the country of origin it was already being replaced with new technologies that had better parameters.

How to Escape? The Trap of the Transition in the Recent Cinema of Bosnia and Herzegovina (2000-2012)The paper concerns the latest cinema of Bosnia and Herzegovina (2000-2012). Focusing on the cinema of social criticism (represented by movies which try to rethink the new socio-political order gradually emerging in BiH after the war of 1992-95), the authors recognize the Bosnian society as a community captured in the trap of an unfinished system transition. The story of the Bosnian society, simultaneously stuck in a dysfunctional and oppressive state and completely devoid of any prospects for the improvement of this situation, seems to be dominated by several escape strategies into an alternative reality: the nostalgic past, the imagined present or the utopian future. In that sense, the Bosnian cinema of social criticism turns out to be a cinema of social escapism. Jak uciec? Pułapka transformacji w najnowszym kinie Bośni i Hercegowiny (2000-2012)Tekst dotyczy najnowszej kinematografii Bośni i Hercegowiny (2000-2012). Skupienie na nurcie kina krytycznego (do którego zaliczone zostały filmy, które próbują interpretować nowy porządek społeczno-polityczny powoli wyłaniający się w Bośni i Hercegowinie po wojnie z lat 1992-95) pozwala ukazać społeczeństwo Bośni i Hercegowiny jako znajdujące się w pułapce wciąż niedokończonej transformacji systemowej. Opowieść o społeczeństwie z jednej strony uwięzionym w dysfunkcjonalnym i opresyjnym państwie, a z drugiej całkowicie pozbawionym perspektyw i nadziei na poprawę sytuacji, zdominowana jest przez rozmaite strategie ucieczki w alternatywną rzeczywistość: nostalgiczną przeszłość, wyobrażoną teraźniejszość lub utopijną przyszłość. W tym sensie, bośniackie kino krytyczne jawi się jako kino eskapizmu społecznego.

Research background: While entrepreneurship in transition economies is the subject of a growing body of literature, the debate on factors influencing entrepreneurial activity in such economies is still incomplete. This paper extends this debate by focusing on the effect of changes in the economic structure on entrepreneurship in Poland. The findings might be supportive for policymakers in pursuing policy aimed at boosting entrepreneurship in a transition economy. Purpose of the article: The aim of the paper is to investigate the extent to which changes in the economic structure impact entrepreneurial activity in Poland. The paper contributes to the literature by providing empirical support to the pending research efforts to recognize entrepreneurship dimensions in a transition economy. Methods: The hypothesis was tested with fixed effects panel regression with robust standard errors. Data were sourced from the Statistics Poland for all Polish NUTS?2 regions for the period 2003?2017. Panel data are balanced and include 3 600 observations. Findings & Value added: This paper extends previous research on factors affecting entrepre-neurial activity in a transition economy by focusing on the importance of changes in the economic structure for new firm creation. The findings provide evidence of the significant value of the service sector in boosting entrepreneurial activity in Poland. The findings might attract attention of policymakers. Fostering structural change towards smart specialization in services should be regarded when constituting programmes supporting entrepreneurship.

Opis:
The basic information on an algorithm of a family of new triangularprism, 3D-based, hpq/hp-adaptive, solid-to-shell transition finite elements has been presented in the paper, where h, p and q detonate an averaged size as well as longitudinal and transverse orders of approximation of the elements, respectively. Novelty of the elements consists in application of hpq- and hp-approximations in solid and shell parts of the elements, respectively. In that context, crucial parts of the algorithm such as: hierarchical shape functions, modification of the stiffness and nodal forces of the shell part of the elements, and constrained hpq/hp-approximation are elucidated. Usefulness of the elements for modelling and analysis of complex structures is proved by a numerical example.
Algorytm rodziny opartych na podejściu trójwymiarowym, adaptacyjnych, przejściowych elementów skończonych typu hpq/hp. Praca przedstawia algorytm rodziny nowych, opartych na podejściu trójwymiarowym, pryzmatycznych, adaptacyjnych elementów przejściowych od elementów bryłowych do powłokowych. Elementy oparto na aproksymacjach typu hpq/hp, gdzie h,p i q oznaczają średni wymiar elementu oraz wzdłużny i poprzeczny rząd aproksymacji. Istotne novum zapropowanych elementów polega na zastosowaniu w części powłokowej elementu adaptacyjnej aproksymacji typu hp, a w części bryłowej adaptacyjnej aproksymacji typu hpq. W tym kontekście omówiono dokładniej hierarchiczne funkcje kształtu, modyfikacje macierzy sztywności i wektora sił elementów oraz aproksymacje z więzami. Przydatność elementów w modelowaniu i analizie struktur złożonych potwierdzono zamieszczonym przykładem numerycznym.

Opis:
Transition curves connecting straight sections with circular curves and vice versa are present on all types of roads. They are designed to smooth the transition from rectilinear to circular motion. In numerous instances, they are hardly noticeable by road use. Although adequately selected, they increase the safety and comfort of driving. The research aimed to investigate the effectiveness of three most popular curves, in the design of road routes: clothoid, a parabola of the 3rd-degree and Bernoulli lemniscate. Starting from the permissible values of the increment of centripetal acceleration on the transition curves, the minimum lengths of the transition curves for the assumed speeds of the wheeled vehicle were determined. Then, based on the formulas of individual curves, their lengths were calculated, depending on the design speed and the radius of the circular arc. As a result of the research, the differences between the individual curves were obtained. Finally, it was found that due to the unconstrained movement of the vehicle on the road, all curves could be used as transition curves. By slightly adjusting their lengths, we can achieve the appropriate value of the increment of centripetal acceleration. The legitimacy of using different curves as transition curves lies primarily in their different geometric appearance. The choice of the curve to be used is based primarily on the terrain conditions and the type of the planned section of the route (serpentines, turnouts, etc.).

Opis:
Studies about the transition to university emphasise the importance of the process of adaptation in the first year as a determining persistence factor. This article presents the results of the focus groups held with students of two undergraduate degree programmes, Pedagogy and Business Management and Administration, at the Universityof Barcelona(Catalonia, Spain) that dealt with the more significant situations they experienced in the process of adapting to life at university. The results are based on the five main tasks in the process of transition to university: starting and developing new social relationships; adjusting expectations about the university and degree programme; adapting to new academic codes at university; coping with academic/exam results; and construction of the university identity. These five tasks are identified in three moments in the initial period of adaptation. This study forms part of a Research+Development project.

Opis:
In this paper, the results of experimental investigations relating to the influence of negative and positive jet of the wake on laminar-turbulent transition in the boundary layer on a flat plate are described. Using the technique of phase averaging and wavelet analysis, the investigations were carried out in an aerodynamic tunnel with a low level of turbulence in the external stream. The existence of serious differences was noted between the influence of the negative and positive jets due to strong velocity impulses appearing in the area behind the negative jet in the place of the local minimum of the velocity. However, behind the positive jet such strong disturbances appear later, not directly in the region behind the jet. These impulses do not show any signs of chaos and fortuity, therefore they should be rather classified as determined disorder. Moreover, the region of calm behind the positive jet, well-known in the literature, remains also in the area of entirely disturbed flow.
W pracy przedstawiono badania eksperymentalne dotyczące wpływu ujemnego i dodatniego strumienia śladu spływowego na przejście laminarno-turbulentne w warstwie przyściennej na płaskiej płycie. Badania przeprowadzono w tunelu aerodynamicznym o niskim poziomie turbulencji przepływu zewnętrznego, wykorzystując technikę fazowego uśredniania i analizy falkowej. Stwierdzono istnienie poważnych różnic między oddziaływaniem ujemnego i dodatniego strumienia w postaci silnych impulsów prędkości pojawiających się w obszarze za ujemnym strumieniem w miejscu o lokalnego minimum prędkości. Za dodatnim strumieniem takie silne zaburzenia pojawiają się później i nie bezpośrednio za nim. Ponadto regiony uspokojenia za dodatnim strumieniem, dobrze znane z literatury, są dobrze widoczne także w rejonie całkowicie zaburzonego przepływu.

Opis:
A survey is given of different kinds of metal-insulator transitions (MIT) in doped semiconductors. The role of electron-electron Coulomb interactions and of disorder is discussed vis-a-vis millikelvin experimental results for semimagnetic semiconductors (SMSC) in the vicinity of MIT. Critical behavior of conductivity tensor components and dielectric susceptibility at the magnetic field-induced MIT in p-type Hg$\text{}_{1-x}$Mn$\text{}_{x}$Te is compatible with the model in which the MIT is a result of quantum localization driven by disorder-modified electron-electron interactions. At the same time the critical behavior of the Hall coefficient suggests that, in addition to electrons forming the Fermi liquid (FL) and undergoing localization at the MIT, there is certain a concentration of local electron moments, even on the metallic side of the MIT. The formation of these moments can presumably be described in terms of a disordered Hubbard-Mott model.

This paper carries out a comparative analysis of the degree of financial development between transition economies and developed ones based on variables that indicate the direct and indirect degree of financial development. To determine the way the financial systems works and the level of its development, the authors have taken into account four general characteristics of financial institutions and financial markets which were measured for the financial institutions (mainly banks, which are the most important financial institutions in most economies in transition, insurance companies and other financial institutions) as well as for the financial markets, thus leading to a 4x2 matrix of the main characteristics of the financial system. The analysis was developed based on the data found on the Global Financial Development database of the World Bank. Empirical data and authors’ analysis were used to characterize and compare financial systems between countries with economies in transition and developed countries for the years 2008 – 2011. The year 2011 was the last year of available qualitative data for many countries in the Balkan Region such as Albania, Kosovo and Macedonia.

Opis:
The primary objective of the present paper is an attempt at evaluating the influence of sub-level caving operations on the slope stability of a still-functioning open pit coal mine in Vietnam. Initially, various methods of predicting the impact of under- ground mining on surface stability are discussed. Those theoretical considerations were later utilized in the process of constructing a Flac-2D-software-based numerical model for calculating the influence of underground operation on the deformation and possible loss of stability of an open pit slope. The numerical analysis proved that the values of open pit slope displacements were affected mainly by underground exploitation depth, direction of operation (i.e., from one slope to the other) and the distance from the slope plane. Real geomechanical strata parameters from the Vietnamese coal basin of Cam Pha were used in the modeling process. The paper is, therefore, a critical review of the hitherto proposed methods of predicting the impact of underground operation (UG) on open pit mining (OP), illustrated with selected examples of case studies on OP-UG interaction, followed by an original experiment based on numerical modeling method. This is first such study for the genuine conditions of the coal mining in Vietnam. The obtained results, however, should not be generalized due to a highly specific character of the analyzed phenomenon of mining-induced surface deformation. The practical implications of the study may occur extremely useful in the case of an UG-OP transition. Such a transition is often necessary for both technical and economical reasons, as in some coal basins open pit operations at greater depths occur unfeasible, which calls for a proper selection of parameters for a planned underground operation.

Most of the publications concerning Polish political and economical transitions emphasize its assumptions and course of events. This article aims at revealing the premises of the success of Polish transition. The method of research applied in this text is the analysis of wide range of documentation concerning conceptions of Polish economists before year of 1990, Solidarity Movement Archives, Archives of Polish People’s Republic. This analysis led the authors to conclusions that there were many reasons for quick start and success of first stage of the Polish transition. These main factors are: qualifications of Polish economists and their invaluable contacts with western colleagues, the Balcerowicz Plan and the way it was put into practice, the help of international institutions as IMF and WB and the great social support for that painful economical changes.

The transition effect between different track-foundation systems is examined from the point of view of energy that is produced during the passage of load. Analytical solution is given. A model of beam on elastic foundation with damping is used as the base model. It is developed into a model composed of two parts that represent the track-subgrade system with an abrupt change in mechanical parameters: bending stiffness, foundation stiffness, damping, and mass. Several calculations are carried out including examples of comparative calculations with the Finite Difference Model and the Finite Element Model. Transient rail deflections and energy are determined, which may serve to estimate the rate of track-subgrade deterioration.

Opis:
This paper represents new results obtained by its authors while searching for the proper shape of polynomial railway transition curves (TCs). The search for the proper shape means the evaluation of the curve properties based on chosen dynamical quantities and generation of such shape with use of mathematically understood optimisation methods. The studies presented now and in the past always had got a character of the numerical tests. For needs of this work advanced vehicle model, dynamical track-vehicle and vehicle-passenger interactions, and optimisation methods were exploited. In this software complete rail vehicle model of 2-axle freight car, the track discrete model, and non-linear description on wheel-rail contact are used. That part of the software, being vehicle simulation software, is combined with library optimisation procedures into the final computer programme. The main difference between this and previous papers by the authors are the degrees of examinated polynomials. Previously they tested polynomial curves of odd degrees, now they focus on TCs of 6th, 8th and 10th degrees with and without curvature and superelevation ramp tangence in the TC’s terminal points. Possibility to take account of fundamental demands (corresponding values of curvature in terminal points) concerning TC should be preserved. Results of optimisation are compared both among themselves and with 3rd degree parabola. The aim of present article is to find the polynomial TCs’ optimum shapes which are determined by the possible polynomial configurations. Only one dynamical quantities being the results of simulation of railway vehicle advanced model is exploited in the determination of quality function (QF1). This is: minimum of integral of vehicle body lateral acceleration.
