Abstract

In the present article the author describes the issue of relation between Synagogue and Church in the context of Johannine writings. The author makes analysis of the Johannine texts in order to show the traces of polemic between Judaism and Christianity. He shows the hostility between Synagogue and Church in the light of terms like aposunagōgos, “Jews” and other polemical expressions which occur in the Gospel of John, in the Letters of John and the Book of Revelation. The author tries to answer the question of how Sitz im Leben of the Johannine writings influences their content. The analysis of Jewish and Christian sources shows the tension and hostility between Rabbinic Judaism and Johannine Community after the destruction of the Jerusalem Temple. It leads to gradual separation between Synagogue and Church. In this article there are shown the reasons for the parting of the ways between Judaism and Christianity and its meaning for the contemporary dialogue between Synagogue and Church.

Abstract

The article presents the most frequent surname in Lithuania — Kazlauskas. Referring to the article “Mysterious Lewandowski” by K. Skowronek (2000), an attempt has been made to account for this frequency in three various ways. First, the principles behind the quantitative structure of anthroponomasticons (Zipf’s law) and the loss of surnames (genetic drift) are discussed. Then the Slavic origin of the surname under consideration has been highlighted as a typical trait of the majority of surnames in Lithuania. In connection with this fact, it has been stressed that caution must be exercised in proposing a thesis on its origin as a translation from Lithuanian on a mass scale, since this thesis requires plentiful empirical evidence. Finally, the etymology of the name is analyzed. Morphologically it is a typical surname derived from a toponym. This supposition is additionally supported by the existence in Poland of numerous localities called Kozłów, Kozłowo or similar name; these in turn are most likely to have been derived from appellative-based personal names of their owners or inhabitants, such as Kozieł.

Abstract

The advent of language implementation tools such as PyPy and Truffle/Graal have reinvigorated and broadened interest in topics related to automatic compiler generation and optimization. Given this broader interest, we revisit the Futamura Projections using a novel diagram scheme. Through these diagrams we emphasize the recurring patterns in the Futamura Projections while addressing their complexity and abstract nature. We anticipate that this approach will improve the accessibility of the Futamura Projections and help foster analysis of those new tools through the lens of partial evaluation.

Abstract

Post-Quantum Cryptography (PQC) attempts to find cryptographic protocols resistant to attacks by means of for instance Shor's polynomial time algorithm for numerical field problems like integer factorization (IFP) or the discrete logarithm (DLP). Other aspects are the backdoors discovered in deterministic random generators or recent advances in solving some instances of DLP. The use of alternative algebraic structures like non-commutative or non-associative partial groupoids, magmas, monoids, semigroups, quasigroups or groups, are valid choices for these new kinds of protocols. In this paper, we focus in an asymmetric cipher based on a generalized ElGamal non-arbitrated protocol using a non-commutative general linear group. The developed protocol forces a hard subgroup membership search problem into a non-commutative structure. The protocol involves at first a generalized Diffie-Hellman key interchange and further on the private and public parameters are recursively updated each time a new cipher session is launched. Security is based on a hard variation of the Generalized Symmetric Decomposition Problem (GSDP). Working with GF(2518) a 64-bits security is achieved, and if GF(25116) is chosen, the security rises to 127-bits. An appealing feature is that there is no need for big number libraries as all arithmetic if performed in Z251 and therefore the new protocol is particularly useful for computational platforms with very limited capabilities like smartphones or smartcards.

Abstract

In this paper, we describe secure gateway for Internet of Things (IoT) devices with internal AAA mechanism, implemented to connect IoT sensors with Internet users. Secure gateway described in this paper allows to (1) authenticate each connected device, (2) authorise connection or reconguration performed by the device and (3) account each action. The same applies to Internet users who want to connect, download data from or upload data to an IoT device. Secure Gateway with internal AAA mechanism could be used in Smart Cities environments and in other IoT deployments where security is a critical concern. The mechanism presented in this paper is a new concept and has been practically validated in Polish national research network PL-LAB2020.

Abstract

In this paper we propose right-angled Artin groups as a platform for secret sharing schemes based on the efficiency (linear time) of the word problem. Inspired by previous work of Grigoriev-Shpilrain in the context of graphs, we define two new problems: Subgroup Isomorphism Problem and Group Homomorphism Problem. Based on them, we also propose two new authentication schemes. For right-angled Artin groups, the Group Homomorphism and Graph Homomorphism problems are equivalent, and the later is known to be NP-complete. In the case of the Subgroup Isomorphism problem, we bring some results due to Bridson who shows there are right-angled Artin groups in which this problem is unsolvable.

Abstract

We demonstrate a modularity bug in the interface system of Java 8 on the practical example of a textbook design of a modular interface for vector spaces. Our example originates in our teaching of modular object-oriented design in Java 8 to undergraduate students, simply following standard programming practices and mathematical denitions. The bug shows up as a compilation error and should be xed with a language extension due to the importance of best practices (design delity).

Abstract

SQL Injection is one of the vulnerabilities in OWASP's Top Ten List forWeb Based Application Exploitation. These type of attacks take place on Dynamic Web applications as they interact with databases for various operations. Current Content Management System like Drupal, Joomla or Wordpress have all information stored in their databases. A single intrusion into these type of websites can lead to overall control of websites by an attacker. Researchers are aware of basic SQL Injection attacks, but there are numerous SQL Injection attacks which are yet to be prevented and detected. Over here, we present the extensive review for the Advanced SQL Injection attack such as Fast Flux SQL Injection, Compounded SQL Injection and Deep Blind SQL Injection. We also analyze the detection and prevention using the classical methods as well as modern approaches. We will be discussing the Comparative Evaluation for prevention of SQL Injection.

Abstract

The availability of cheap and widely applicable person identification techniques is essential due to a wide-spread usage of online services. The dynamics of typing is characteristic to particular users, and users are hardly able to mimic the dynamics of typing of others. State-of-the-art solutions for person identification from the dynamics of typing are based on machine learning. The presence of hubs, i.e., few instances that appear as nearest neighbours of surprisingly many other instances, have been observed in various domains recently and hubness-aware machine learning approaches have been shown to work well in those domains. However, hubness has not been studied in the context of person identification yet, and hubnessaware techniques have not been applied to this task. In this paper, we examine hubness in typing data and propose to use ECkNN, a recent hubness-aware regression technique together with dynamic time warping for person identification. We collected time-series data describing the dynamics of typing and used it to evaluate our approach. Experimental results show that hubness-aware techniques outperform state-of-the-art time-series classifiers.

Abstract

In the 19th and in the first half of the 20th century numerous parks were built all over Europe, which, though different in many aspects, still show certain similarities in space structure and composition. The question is, whether late modern public parks, built in the second half on the 20th century follow the classical design and composition „rules”? How did the extremely functionalist design approach of the era after WW2 influence park design? The answer is the result of a detailed analysis on space structure and composition principles of the parks built in these times. In this research I analyzed according to specific criteria the Jubileum Park in Budapest, one of the most prominent work of the late modern period in Hungary. The 12 ha Jubileum Park (built in 1965) is located in the heart of Budapest, on the top of Gellért Hill, next to river Danube. Laying high above the city on an exposed hillside, the park offers a broad view of the whole city. The structure of the park is basically determined by the extreme topography, and one of the great value of the park is the natural looking grading, which determines the space structure and fits to the natural terrain very nicely, and the walkway system, which fits to the contour lines and explores the whole site. Fitting to the windy and exposed hilltop position, in space division the terrain in the most appealing, the plantation is only secondary. From formal point an interesting feature is the dominance of two dimensional elements with characteristic shape, like flowerbeds or ornamental pools and the curves of the walkway system. Though the main function of the park is to underline the fantastic visual potential with providing viewpoints, there are some playgrounds as well. For the visitor of today the specialty of the park celebrating the 50th anniversary this year, is, that – disregarding some minor changes – there were no alterations since it exists. As a first step I analyzed the space structure of the park, putting an extra emphasis on the existence or lack of any axis, on the accentuation of the park entrances, on the space organization inside the park and on the existence/lack of hierarchy. Important aspect of analysis was the connection of the park to connecting urban fabric and green surfaces nearby. The next step was to compare the results with other parks built in former times, but having similar natural setting. The goal of the research is to determine, how much the spatial composition of Jubileum Park is different from the spatial composition of classical parks. The results might help to realize, what kind of spatial composition and space structure is typical of late modern parks. It would be important to preserve these space structural specialties of the Jubileum Park during a more and more urgent renovation.

Abstract

The study of the relationship “the natural qualities of water – the naturally built environment – the psycho- emotional conditions of human beings” from the perspective of architectural and landscape organization is essential nowadays. By investigating modern monuments we identified the methods of landscaping and composition planning to create the appropriate environment to emotionally impact the persons dealing with grief, sadness and loss. The conducted analysis of modern memorials allowed us to explore the role of water as an important compositional element in the architectural and landscape organization of monument sites. We also identified different methods of modeling water and how they affect related emotional impressions in creating the urban social environment that would preserve the historical and cultural memory from generation to generation.

Abstract

The public demand for urban parks, citizens’ use and habits are different in every age and region. But do public parks have some eternal, unchanging values in a field of social welfare? Can we regard the idea as a value, which brought to life the 18th century public park movement in today’s rushing, tinsel and digital world? Can we find any general aspect in park use forms, which is true, even to the casual visitor or a tourist in a historical garden or a daily guest in an average city park. The Budapest Városliget is one of the world’s first urban park, in some ways perhaps the first. The site was used for urban recreation from mid-18th century, and then the city of Pest decided to develop a public park to increase the livability of the city. The plan was drawn up by Heinrich Nebbien between 1813–1816. Although Nebbien’s plan realized partly due to the lack of resources, in the capital’s life the Városliget have been acting – with changing functions and space structure – as a vital part of the open space recreation for 200 years. This article focuses on the role of urban public parks, and analyses the relationship between changing space structure and use on the example of Városliget. The Városliget analysis is based on the structural and park user surveys, which were made during the last three decades. The history of the urban park clearly illustrates that cramming new functions beyond the historical outdoor recreational activities has not increased the value of the park, but significantly deteriorate what is value and what makes the park loveable. It is almost understandable that the park is not on the international tourism program, it does not appear on the map of the capital’s iconic creations, institutions. But it could be there. Everything predestines for it: two centuries of history, the idea of its birth and creation, its location in the city structure, its current old and valuable trees. The Városliget is a value in itself, without stuffing and subsuming with new institutional functions.

Abstract

In 1847, the City Council of Pest opened a new central necropolis. In 1956, the cemetery was declared to be a National Pantheon and Graveyard. Nowadays, about half of the territory of the cemetery is settled, the individually or artistically remarkable tombs are protected, and the rest of the site is being re-designed as green area. In some parts of the cemetery, burials can still be carried out, but the major part of the graveyard is functioning as a public park.

Abstract

Based on a study of Polish migrants living in England and Scotland, this paper explores how Polish families who have decided to bring up their children in the UK make initial school choices. The Polish parents taking part in our study generally had low levels of social and cultural capital (Bourdieu 1986) upon arrival in the UK: they had limited networks (predominantly bonding capital) (Putnam 2000) and a poor command of English, and lacked basic knowledge of the British education system. Meanwhile, this is a highly complex system, very much different from the Polish one; moreover, school choice plays a much more important role within the UK system, especially at the level of secondary education. We found that while some parents acted as ‘disconnected choosers’ (Gewirtz, Ball and Bowe 1995) follow-ing the strategy they would use in Poland and simply enrolling their children in the nearest available school, others attempted to make an informed choice. In looking for schools, parents first and foremost turned to co-ethnic networks for advice and support; nevertheless, parents who attempted to make an informed choice typically lacked ‘insider knowledge’ and often held misconceptions about the British education system. The one feature of the system Polish parents were very much aware of, however, was the existence of Catholic schools; therefore, religious beliefs played a key role in school choice among Polish parents (with some seeking and others avoiding Catholic schools). The ‘active choosers’ also made choices based on first impressions and personal beliefs about what was best for their child (e.g. in terms of ethnic composition of the school) or allowed their children to make the choice. Parents of disabled children were most restricted in exercising school choice, as only certain schools cater for complex needs. All in all, the Polish parents in our sample faced similar barriers to BME (Black Minor-ity Ethnic) parents in exercising school choice in the UK and, regardless of their own levels of education, their school selection strategies resembled those of the British working class rather than of the middle class. However, the risk of ‘bad’ initial school choice may be largely offset by a generally strong pref-erence for Catholic schools and parents’ high educational ambitions for their children.

Abstract

The issue of the educational system remains one of the crucial areas for the discussions pertaining to migrants’ integration and contemporary multicultural societies. Ever since the inception of compulsory schooling, children and youth have partaken in largely state-governed socialisation in schools, which provide not only knowledge and qualifications, but are also responsible for transferring the culture and values of a given society. Under this premise, the schooling system largely determines opportunities available to migrant children. This paper seeks to address the questions about the pathways to youth Polish migrant integration, belonging and achievement (or a lack thereof) visible in the context of the Norwegian school system. The paper draws on 30 interviews conducted in 2014 with Polish parents raising children abroad, and concentrates on the features of Norwegian school as seen through the eyes of Polish parents. Our findings show that the educational contexts of both sending and receiving socie-ties are of paramount importance for the understanding of family and parenting practices related to children’s schooling. In addition, we showcase the significance of Norwegian schools for children’s integration, illuminate the tensions in parental narratives and put the debates in the context of a more detailed analysis of the relations between school and home environments of migrant children. The paper relies on parental narratives in an attempt to trace and reflect the broader meanings of children’s education among Poles living abroad.

Abstract

Poles are today the largest group of family immigrants to Norway. Since Polish immigration is an intra-Euro-pean movement of labour, there are no specific laws or regulations, apart from labour regulations, pertaining to the introduction of Polish families to Norway and their settlement there. Consequently, there are few guidelines in schools and local authorities on dealing with Polish children in school. They receive the same introduction to school as immigrants from any other background, with no considera-tion of the specific characteristics of Poles. Equally, their parents are not eligible for the orientation courses and language classes that are offered to adult asylum seekers or refugees. As these are expen-sive, many Polish parents postpone language classes until they can afford them or find alternative ways of learning language and culture. In this article, I explore the inclusion of Polish children in Norwegian schools through the voices of teachers receiving Polish children in their classrooms and Polish mothers of children attending school in Norway. Interviews with both teachers and mothers reveal inadequate understandings of each other’s conceptions of school, education and the roles of home and school in the education of children. They also demonstrate a limited understanding of culturally bound interpre-tations of each other’s actions. Although both sides are committed to the idea of effective integration, we risk overlooking the social and academic challenges that Polish children face in Norwegian schools unless conceptions and expectations of school and education are articulated and actions are explained and contextualised. There is also a risk that cultural differences will be perceived as individual prob-lems, while real individual problems may be overlooked due to poor communication between schools and families. The data is drawn from an extended case study including classroom observations, inter-views with teachers and Polish mothers in Norway, and focus groups of educators and researchers in the field of social work.

Abstract

This article discusses and expands on two related issues. The first is the unexplored reasons for the departure of Polish migrant women: the forced migration phenomenon. The author describes the system behind forced migration as created at the intersections not only of care, gender and migration regimes but also of legal regimes. Second, the author points out that the close relation between forced migration and the process of ‘unbecoming a wife in the transnational context’ creates a distinctive type of trans-national motherhood experience. In order to explain the specificity of these types of experiences better the author introduces a new typology of transnational motherhood biographies. The case study of Al-dona is representative of the experiences of some Polish women in the period under study, 1989–2010.

Abstract

This article, through the prism of immigration policy models proposed by Stephen Castles (1995), Steven Weldon (2005) and Liah Greenfeld (1998), discusses those aspects of Norwegian immigration policy that refer directly to children. Areas such as employment, education, housing and health care influence the situation of an immigrant family, which in turn affects the wellbeing of a child. However, it is the education system and the work of Child Welfare Services that most directly influence a child’s position. Analysis presented in this article is based on the White Paper to the Norwegian Parliament, and data that were obtained in expert interviews and ethnographic observation in Akershus and Buskerud area in Norway, conducted between 2012 and 2014. The article raises the question whether the tools of im-migration policy used by social workers and teachers lead to integration understood as an outcome of a pluralist or individualistic-civic model of immigration policy or are rather aimed at assimilation into Norwegian society, attempting to impose the effect of assimilation or the collectivistic-civic policy model.

Abstract

The article provides a sociological analysis of national identities of Polish children growing up in Nor-way. The research results presented are unique in the sense that the portrayals of national identifica-tions constructed in the process of migration are shown through direct experiences of children. The analysis is based on semi-structured interviews with children, observation in the research situation (children’s rooms) and Sentence Completion Method. Adopting Antonina Kłoskowska’s analytical framework of national identity and her terminology of the so called ‘cultural valence’ (adoption of cul-ture), we argue that identities are processual and constructed, a result of the fact that mobility took place at a certain moment in time and in a specific geographical space. In addition, we see identities as conditioned by a plethora of identifiable objective and subjective reasons. The intensified mobility of children due to labour migrations of their parents leads to multiple challenges within the (re)construc-tions of children’s identities in their new place of settlement.

Abstract

This article sheds light on the unintended consequences of temporary migration from Poland by com-bining Merton’s functional analysis with Levitt’s work on social remittances. In addition to economic remittances, Polish migrants have been bringing norms, values, practices and social capital to their communities of origin since the end of the nineteenth century. The article presents a juxtaposition of the non-material effects of earlier migration from Poland, dating from the turn of the twentieth century, with those of the contemporary era of migration from Poland since the 1990s. The analysis shows that some aspects, such as negotiating gender roles, the changing division of household labour, individualistic lifestyles, new skills and sources of social capital, and changing economic rationalities are constantly being transferred by migrants from destination to origin communities. Con-temporary digital tools facilitate these transfers and contribute to changing norms and practices in Polish society. The article demonstrates that migration fulfils specific functions for particular sections of Polish society by replacing some functions of the communist state (e.g., cash assistance and loans from communist factories, factory and post-coop cultures) and by facilitating their adaptation to chang-ing conditions (e.g., changing gender relations, new models of family, job aspirations and social mobility).
