Opis:
Sektor MSP od lat należy do najdynamiczniej rozwijających się i informatyzujących obszarów polskiej gospodarki. Zaawansowane rozwiązania ICT (Information and Communication Technology) stanowią warunek sine qua non nowocześnie funkcjonujących przedsiębiorstw tego sektora i wpisują się w proces transformacji cyfrowej. W artykule omówiono aktualne tendencje rozwojowe w zakresie informatyzacji nowoczesnych przedsiębiorstw sektora MSP. Dokonano tego na bazie wyników badań własnych autora przeprowadzonych w okresie 2014–2016 w wybranych przedsiębiorstwach województw mazowieckiego i wielkopolskiego oraz odniesiono je do ogólnych tendencji rozwojowych w zakresie globalnej transformacji cyfrowej.
An active sector of small and medium enterprises (SME) in Poland is a prerequisite of a properly functioning market economy. This sector encompasses various companies. The ICT (Information and Communication Technology) can help even the odds. SMAC (social, mobile, analytics and cloud) is the concept that four technologies are currently driving business innovation. SMAC creates an ecosystem that allows a business to improve its operations and get closer to the customer with minimal overhead and maximum reach. We have conducted a questionnaire-based survey to identify how polish SMEs perceive this phenomenon of e-business systems in era of digital transformation.

Opis:
Market transition in Central and Eastern Europe triggered many new socioeconomic developments. One of them was the appearance of open unemployment vastly different from that noted in most developed economies around the world. As a result, the term “transformation unemployment” began to be used in literature on the subject. The authors of the article analyze the trend from a theoretical point of view and then follow up with an empirical study of unemployment. They present changes in the labor force and GDP in several groups of countries: Central Europe (Czech Republic, Poland, Slovakia and Hungary) plus Slovenia; Lithuania, Latvia and Estonia; Russia, Ukraine, Belarus and Moldova; Georgia, Armenia and Azerbaijan; and Balkan countries (former Yugoslav states except Slovenia as well as Albania, Bulgaria and Romania). The authors offer a statistical analysis of GDP growth and unemployment in individual groups of countries. In the final part of the article, the most important conclusions are summed up. These include the fact that the analyzed groups of countries display major differences in unemployment rates, along with changes in employment figures and labor productivity. Moreover, in most these countries, GDP growth has had a limited effect on unemployment. The only exception is Central Europe, though the European members of the Commonwealth of Independent States and transition economies in the Balkans also stand out positively.

Opis:
Sometimes you may judge the book by its cover. Those familiar with the works of Guglielmo Meardi know very well that his name as the author usually signals a controversial, if not a provocative content. Italian-born Meardi, who currently is the Head of prestigious Industrial Relations Research Unit at the Warwick Business School, has been covering developments in the field of work and employment relations in Europe for more than two decades, paying special attention to transformations of that field in the Central and Eastern Europe (CEE). He pioneered field research in the Polish a# liates of multinational corporations. In $%%$ Meardi stepped forward with a thesis that fuzziness, disorganization and hybridity of Polish industrial relations make our country look like an ‘American Trojan horse (Meardi 2002), posing a threat to the foundations of European Social Model. Ten years later the Author does not hesitate to formulate even more acute diagnosis, writing openly about EU’s lack of capability to maintain the social dimension of European integration after the 2004-2007 enlargement. In his book Meardi claims that the accession of post-communist countries to the EU produced a convenient excuse for undermining the idea of the intrinsic nature of work as a value, which should not be assessed only from a market perspective, as either profitable or not. What happened in the New Member States (NMS) from the CEE after the accession, serves as the evidence.

Celem pracy jest wskazanie zmian w krajobrazie rolniczym wynikających z przerwania ciągłości osadnictwa. Skutki krajobrazowe utraty ciągłości kulturowej omówiono na przykładzie dorzecza Wiaru w Polskich Karpatach Wschodnich, obszaru reprezentatywnego dla regionów, w których w wyniku wysiedleń ludności powstały trwałe pustki osadnicze. Wielkość i kierunek przemian krajobrazu określono z wykorzystaniem analizy kartograficznej map archiwalnych w podejściu HGIS (ang. Historical GIS). Opracowana w 2015 r. przez J. Plit regionalizacja współczesnych krajobrazów historyczno-kulturowych Polski stanowiła ramy teoretyczne do prowadzonych rozważań.
The aim of the study is to identify changes in rural landscape resulting from the break in the continuity of settlement. Landscape effects of cultural decline are presented on the example of Wiar River basin in Polish Eastern Carpathians, an area representative for the regions, where after displacement of inhabitants human population has been hardly restored. The magnitude and direction of changes in landscape structure were determined by means of cartographic analysis of archival maps in Historical GIS approach. The historical-cultural regionalization of Polish landscape developed by J. Plit in 2015 was adopted as theoretical framework for further considerations.

Opis:
A compliant beam subjected to large deformation is governed by a multifaceted nonlinear differential equation. In the context of theoretical mechanics, solution for such equations plays an important role. Since it is hard to find closed-form solutions for this nonlinear problem and attempt at direct solution results in linearising the model. This paper investigates the aforementioned problem via the multi-step differential transformation method (MsDTM), which is well-known approximate analytical solutions. The nonlinear governing equation is established based on a large radius of curvature that gives rise to curvature-moment nonlinearity. Based on established boundary conditions, solutions are sort to address the free vibration and static response of the deforming flexible beam. The geometrically linear and nonlinear theory approaches are related. The efficacy of the MsDTM is verified by a couple of physically related parameters for this investigation. The findings demonstrate that this approach is highly efficient and easy to determine the solution of such problems. In new engineering subjects, it is forecast that MsDTM will find wide use.

Opis:
The problem of boundary layer flow and heat transfer of nanofluids over nonlinear stretching of a flat sheet in the presence of a magnetic field and chemical reaction is investigated numerically. In this paper, a new locally modified single-phase model for the analysis is introduced. In this model, the effective viscosity, density and thermal conductivity of the solid-liquid mixtures (nanofluids) which are commonly utilized in the homogenous single-phase model, are locally combined with the prevalent single-phase model. Similarity transformation is used to convert the governing equations into three coupled nonlinear ordinary differential equations. These equations depend on five local functions of the nanoparticle volume fraction viz., local viscosity ratio, magnetic, Prandtl, Brownian motion and thermophoresis functions. The equations are solved using Newton’s method and a block tridiagonal matrix solver. The results are compared to the prevalent single-phase model. In addition, the effect of important governing parameters on the velocity, temperature, volume fraction distribution and the heat and mass transfer rates are examined.

Opis:
Background: Model transformations play a key role in Model-Driven Engineering (MDE). Testing model transformation is an important activity to ensure the quality and correctness of the generated models. However, during the evolution and maintenance of these model transformation programs, frequently testing them by running a large number of test cases can be costly. Regression test selection is a form of testing, which selects tests from an existing test suite to test a modified program. Aim: The aim of the paper is to present a test selection approach for the regression testing of model transformations. The selected test case suite should be smaller in size than the full test suite, thereby reducing the testing overhead, while at the same time the fault detection capability of the full test suite should not be compromised. Method: approach is based on the use of a traceability mapping of test cases with their corresponding rules to select the affected test items. The approach is complemented with a tool that automates the proposed process. Results: Our experiments show that the proposed approach succeeds in reducing the size of the selected test case suite, and hence its execution time, while not compromising the fault detection capability of the full test suite. Conclusion: The experimental results confirm that our regression test selection approach is cost-effective compared to a retest strategy.

Opis:
Concept. COVID-19 has pressed the need for social distancing that was unprecedentedly invoked across societies during the pandemic. The governments that launched emergency steps to divert physical learning systems into online pedagogical alternatives created critical possibilities and adverse challenges for both tutors and learners. The study aims to review several cases concluding that the closure of schools and colleges has impacted around 94% of the student population across globe. The present study tries to comprehend the transformation (both expansion and constraints) in the pedagogical processes comparing results and feedback from both developed and developing nations. Result and Discussion. The study made a far-reaching analysis on the sweeping impact of COVID-19 at the integrative three-tier educational level i.e., primary, secondary and higher education in two separate perspectives i.e., teachers and learners. The restrictive movement policies adopted by governments have changed the conventional (face-to-face) educational practices. The findings suggest that different populations faced different problems during the pandemic because of number of reasons which is discussed and highlighted in the study. Originality. In order to map efficacy and efficiency, the principles, difficulties, and praxis of online educational pedagogy have been comprehensively examined in the study. The key contribution of the research is the result claiming the potential of technology as well as the obstacles faced by students while learning, due to digital mechanisms.

Opis:
Directed by Ricardo Abad and choreographed by Matthew Santamaria, Sintang Dalisay—a Filipino adaptation of Shakespeare’s Romeo & Juliet—is often lauded for its use of the igal ethnic dance of the Sama-Badjau, a Muslim tribe located in the southern region of the Philippines. It depicts Rashiddin and Jamillia’s star-crossed love amidst a violent and ancient feud between their families. This paper discusses the process and product of interweaving performance traditions and cultures in Sintang Dalisay and how the adaptation transforms Shakespeare’s Romeo and Juliet from tragic to utopic. It does so in two aspects: the kinesthetic and the mythic. First, the use of the igal dance motif expresses and unearths the play’s inherently religious and celestial language. Second, the appropriation of Asian myths or beliefs—particularly of Chinese and Filipino origins—transforms and transcends the tragic ending of Romeo and Juliet’s deaths.

Opis:
This paper introduces a new generalization of the Pareto distribution using the Marshall Olkin generator and the method of alpha power transformation. This new model has several desirable properties appropriate for modelling right skewed data. The Authors demonstrate how the hazard rate function and moments are obtained. Moreover, an estimation for the new model parameters is provided, through the application of the maximum likelihood and maximum product spacings methods, as well as the Bayesian estimation. Approximate confidence intervals are obtained by means of an asymptotic property of the maximum likelihood and maximum product spacings methods, while the Bayes credible intervals are found by using the Monte Carlo Markov Chain method under different loss functions. A simulation analysis is conducted to compare the estimation methods. Finally, the application of the proposed new distribution to three real-data examples is presented and its goodness-of-fit is demonstrated. In addition, comparisons to other models are made in order to prove the efficiency of the distribution in question.
