Opis:: Aim. This research paper discusses the educational process of immigrant children in Lithuania with the intention to determine the integration trajectory most likely to be chosen by the immigrant students. Methods. The research methods include legal analysis of Lithuanian legislations related to immigration, immigrant integration and education, meta-analysis of previous research on immigrant integration into Lithuanian society as well as semi-structured interviews with experts of the field. Results. Having completed the research, the following conclusion has been drawn: immigrant children education in Lithuania does not tend to create conditions for successful integration and more often than not influences immigrant students to choose those integration paths that may inspire inner or outer conflict. This is due to the lack of integration policy and strategy at the state level as well as the tendency to create a cultural hierarchy wherein the Lithuanian culture is implicitly considered as above others. Practical application. The results of the research can be used to improve the conditions of immigrant children education in Lithuanian schools on the national level as well as by schools willing to foster the integration of immigrant students; the results can also be considered in the process of establishing integration policy on the state level.

Opis:: Production, processing and consumption within Slovenian agrarian space are fragmented due to physical constraints (72.4% of the territory categorised as ANC) and socio-geographic factors. Based on available data, five essential building blocks of contemporary Slovenian agrarian space (available land, change management, integrated circular economy, adjustable policies, and flexibility of institutions) are discussed. Interrelations among the building blocks shape the modernisation trajectories of approx. 70,000 agricultural holdings in Slovenia. The coexistence of three modernisation trajectories, i.e. practised autarky, various forms of pluri-activity, and small-scale intensive and innovative modernisation, creates a complex mosaic. The governance of multifunctional and multi-structured agrarian space is becoming more demanding.

Opis:: The paper seeks to map the shifting contours of IR (International Relations) research in India from its predominantly area-studies focus towards disciplinary inquiries and within that, from the traditional realist frameworks towards an engagement with critical theories ranging from constructivism and feminism to post-colonialism. With a growing Indian involvement in the domain of global governance, the scholarly research is also going beyond an Indo-centric focus to addressing the diverse problematiques of modern IR as such. The pedagogic practices of Indian IR are however, not matching the pace of such changes. The paper concludes that developing critical pedagogic practices will play a determining role in shaping the future of the IR discipline in India.

Opis:: Family involvement in education is highlighted as a key factor to boost students’ success. In this paper, we analyze ninth-graders’ discourses on how they see family participation in school-related activities. data derive from 38 biographical interviews involving students from eight public schools from North Portugal. Following a narrative approach, findings emphasize that active involvement of parents make up a fundamental dimension for the consolidation of educational projects. data reveal that mothers play a leader role in the educational setting, while fathers’ lack of participation can impact negatively on students’ trajectories. In addition, research indicates that an extended family can emerge as crucial to the maintenance of a schooling project.

Opis:: In his book, Čitanje grada (Reading the City), Krešimir Nemec stated that A.G. Matoš has „modeled after Baudelaire, introduced to the Croatian literature a figure of an idle observer, a curious pedestrian or a flâneur, a typical impressionist product of urban culture and aesthetics of the street”. As a reference and a starting point for reflection on flâneurism’s motifs in contemporary Croatian literature, A.G. Matoš is used as a factor of distinction in outlining one of the most characteristic aspects of the so-called transitional literature. Having said that, a common conclusion is that flâneurism has, in the Croatian contemporary prose, moved from thestreets to the shopping malls. However, contemporary Croatian prose offers the reading of other flâneurism practices as a movement that reflects the changes in categories of urban life, space, daily life and discourse in the transition period from the 20th to the 21st century due to the transformative processes such as a transition, globalization and media revolution. Ultimately, Nemec writes: „If he had experienced the present era of electronics and virtual reality, Matoš probably would have called the tireless surfers of the endless Internet sphere electronic flâneurs”.

Opis:: This paper is about four Japanese university students majoring in international studies, who participated in a two-year study examining changes in their motivation. Using monthly interviews and a 29-item questionnaire on Dörnyei’s (2005) L2 motivational self system that was administered alongside each interview, the trajectories of learner motivation were investigated, based on both quantitative and qualitative data. First, changes in the participants’ motivation were identified using quantitative data. Next, a variety of motivators and demotivators that learners experienced both inside and outside of their classrooms were analyzed using the qualitative data. With the data obtained, this study focuses on how four learners’ language learning motivation and contexts adapt to each other, and how the dynamics of the four learners’ motivation changes due to their learning experiences. Each learner was different in their trajectory of motivation and the kinds of motivators and demotivators that they experienced in their particular contexts. The four learners underwent unique motivators and demotivators, and reacted differently. While participants identified their ideal L2 selves, or ought-to L2 selves, these self-guides were not strengthened by their L2 experiences over time. Based on these findings, the importance of studying the rich experiences of language learners in motivation research is discussed.

Opis:: The motion of deuterons in dynamical filamentary configurations of a PF pinch column has been studied with a three-dimensional numerical model. Apart from magnetic fields, the motion-induced electrical fields as well as ion-ion and ion-electron collisions have been included in the equations of deuteron motion. Calculations were performed for different numbers of filaments and its spatial distributions under different initial conditions. Energy of ions was assumed to be from 10 keV up to 200 keV. The results obtained have shown many possible modes of ion motion and have demonstrated that the current filaments can cause peculiarities observed in the angular distribution of deuterons emitted from the PF pinch column.

Opis:: The method of “in-plane generating trajectories” is a method designed to study the enveloping profiles associated with a pair of rolling centrodes. This method assumes knowledge the analytical form of the in-planes trajectories described by the points onto the profiles to be generated. These trajectories are known in the reference system of the generating tool, which may be a rack-gear, a gear-shaped or a rotary cutter tool. The envelope of these trajectories represents the profile of the generating tool. An original method for determining the enveloping condition is presented in this paper. Application for ordered curling of non-involute profiles were developed based on the specific enveloping condition. A new solution is proposed. This solution uses the capabilities of the CATIA graphical environment. Graphical solutions are proposed versus analytical solutions in order to validate the proposed method.

Opis:: In this paper, a Tectonophysics map of Rybnik region is presented which is based on the method of determining the direction of the trajectory of the principal stresses in the rock mass and axis orientation of these stresses. This method is used in tectonophysicsand is based on the character and parameters of faults. The whole map of Rybnik region encompasses an area of active mines: Rydułtowy-Anna, Marcel, Chwałowice, Jankowice as well as closed ones: Rymer and 1 May of Marcel mine. The paper presents only some fragments of the maps made for the four fault systems and a collective map of tectonophysic, i.e., showing chart areas of compaction for all the systems. The tectonophysics map was made to a scale of 1:20 000. Before the proper work which was the reconstruction of the compaction zone, preparatory work was done. This consisted of updates in 2013 of the tectonics of this area. As a result, tectonic maps were obtained where faults were projected on one level to get their proper azimuth and their inclination. So, a map was made which was used to separate four fault systems arising in similar conditions of stress. Next followed the reconstruction of the main stress fields, which was the cause of faults. On the map there are plotted trajectories showing minimum stress (σ₃) and areas of compaction. The maps thus constructed will be used for further studies on the stress spreading and the impact of these areas for geomechanical properties.
