The general solution of the Frenet system of differential equations for curves in the pseudo-Galilean space { G^1_3}

In this paper the general solution of the Frenet system of differential equations for curves in the pseudo-Galilean space is given. The analogous result in the isotropic (pseudotropic), doubly isotropic and Galilean space are obtained in [3],[4] and [5]. Such result is still unknown in the Euclidean space. There is one particular solution for the Euclidean case in [1] and three particular solutions in [2]

Less is more: possibility and necessity as centres of gravity in a usage-based classification of core modals in Polish

In this paper we present the results of an empirical study into the cognitive reality of existing classifications of modality using Polish data. We analyzed random samples of 250 independent observations for the 7 most frequent modal words (móc, można, musieć, należy, powinien, trzeba, wolno), extracted from the Polish national corpus. Observations were annotated for modal type according to a number of classifications, including van der Auwera and Plungian (1998), as well as for morphological, syntactic and semantic properties using the Behavioral Profiling approach (Divjak and Gries 2006). Multiple correspondence analysis and (polytomous) regression models were used to determine how well modal type and usage align. These corpus-based findings were validated experimentally. In a forced choice task, naive native speakers were exposed to definitions and prototypical examples of modal types or functions, then labeled a number of authentic corpus sentences accordingly. In the sorting task, naive native speakers sorted authentic corpus sentences into semantically coherent groups. We discuss the results of our empirical study as well as the issues involved in building usage-based accounts on traditional linguistic classifications

Spatial Segregation of Roma Settlements Within Serbian Cities. Examples from Belgrade, Novi Sad, and Kruševac

This chapter focuses on the spatial segregation of Roma settlements within Serbian cities, shaped by the long-standing ethnic distance and social exclusion. In order to understand the broader context, the historical background against which Roma settlements emerged in Serbia, as well as their current demographic, legislative, and urban characteristics, are briefly presented. Several forms of segregation of Roma settlements are analysed, including segregation as a consequence of racist hostility, institutional discrimination by city administration, and development-based conflicts. Examples of setting up a wall enclosing a Roma settlement in Kruševac, racist pressures that prevent the construction of housing for Roma in Belgrade and the reluctance to improve and legalise Roma settlements in Novi Sad, illustrate the various manifestations of segregation and division of urban space in Serbia.The Urban Book Serie

Implementation of Learning Outcomes in Mathematics for Non-Mathematics Major by Using E-Learning

Learning outcomes are considered to be a key tool for student-centered teaching and learning. They can be successfully implemented in teaching and learning mathematics on higher educational level and together with appropriate level of technology enhanced learning can provide the framework for successful learning process even for students that have not been primarily interested in mathematics. The aim is to present the case study of implementation of learning outcomes and e-learning in several mathematical courses at the Faculty of Organization and Informatics of the University of Zagreb. First of all, there are examples of mathematical courses in the first year since the first study year is crucial for retaining students. Further, there are mathematical courses taught at higher years of undergraduate study and the first year of graduate study. Again, educational process is appropriately supported by ICT and executed through blended e-learning, as well as the use of social software.</jats:p
