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.

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.

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.

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.

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.

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).

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.

The paper concerns a risk assessment and management methodology in critical infrastructures. The aim of the paper is to present researches on risk management within the experimentation tool based on the OSCAD software. The researches are focused on interdependent infrastructures where the specific phenomena, like escalating and cascading effects, may occur. The objective of the researches is to acquire knowledge about risk issues within interdependent infrastructures, to assess the usefulness of the OSCAD-based risk manager in this application domain, and to identify directions for further R&D works. The paper contains a short introduction to risk management in critical infrastructures, presents the state of the art, and the context, plan and scenarios of the performed validation experiments. Next, step by step, the validation is performed. It encompasses two collaborating infrastructures (railway, energy). It is shown how a hazardous event impacts the given infrastructure (primary and secondary eects) and the neighbouring infrastructure. In the conclusions the experiments are summarized, the OSCAD software assessed and directions of the future works identified.

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.

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.

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.

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.

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.

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.

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.

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).

The process of social remitting is complex and multilayered, and involves numerous social actors that at each stage face several choices. By definition, the process of socially remitting ideas, codes of behav-iour and practices starts with the migrants themselves and their social context in the destination country. This paper focuses on the as yet unexplored issue of resistance performed and articulated by migrants confronted with potential change influenced by social remittances and the generalised process of diffu-sion. Faithful to the understanding of social remittances as ultimately a process where individual agency is the crucial determinant, the article follows the ideas, practices and values travelling across the trans-national social field between Britain and various localities in Poland. Resistance to change and new ways of doing things is a continuous dialogical process within one culture’s power field, which is un-derstood here in anthropological terms as a porous, open-ended field of competing meanings and dis-courses. Notions of bifocality, infra-politics of power relations and resistance are an important aspect of remittances and their reinterpretations, and resistance to social remittances by migrants, both in their destinations and in their communities of origin, is a crucial component of the whole process without which our understanding of remittances is incomplete.

This paper explores how the workplace experience of migrants helps to determine part of the social remittances they can make to their country of origin. The social remittance literature needs to pay more attention to work as an element of the migrant experience. Focus is placed on public internet forums related to newspapers in Poland because these are a very open means of communicating experience to the public sphere. To support the analysis, UK census and other data are used to show both the breadth of work done by Polish migrants in the UK and some of its peculiarities. This is then followed with a more qualitative analysis of selected comments from the gazeta.pl website. The complexities of both the range of migrants’ ideas about their work and also the analysis of internet-based newspaper com-ment sites as a form of public communication are shown.
