The traces of the battle of the Frigid river in Veraldar saga, Ambrósius saga biskups and its potential echoes in Kirialax saga

This article analyzes and discusses the traces which the Battle of the Frigid River and its protagonists left in two Old Icelandic texts: Veraldar saga from the early thirteenth century, and Ambrósius saga biskups from approximately the same period. The Viking Eugenius in the Icelandic romance Kirialax saga, most likely to have been written in the fourteenth century, might have been modelled on the same historical figure as the one referred to in Veraldar saga and Ambrósius saga. In Veraldar saga, the Emperor Theodosius I is described as being the most important figure of his age, a representative of imperial power and a staunch supporter of Christian orthodoxy, while Eugenius is assigned the minor role of usurper. In Ambrósius saga, the battle is described in detail, with the emphasis on hagiographical elements which evolved around the event during the Late Antiquity. In Kirialax saga, the Viking Eugenius, who might have been borrowed from Veraldar saga, is depicted - together with Attila and Theodoric the Ostrogoth - as one of the efficient and intimidating war leaders who were invading Italy during the Late Antiquity, which, by implication, increases the value of Kirialax\u27s victory over such an enem

Bilješke o taxicab geometriji

The taxicab geometry is one of non-Euclidean geometries. Hermann Minkowski (Gesammelte Abhandlungen) introduced this geometry more than 100 years ago. In this hundred years there were the periods of marginalization and the periods of great interest and wide application of this geometry. Today there is a whole specter of application and implementation of the taxicab geometry. There are several reasons for this. First, the taxicab geometry is similar to Euclidean geometry and easy to understand. It can be observed as such a metric system where the points correspond to the intersections of the streets in the imagined city, streets run only horizontally and vertically. There are no one-way streets. From the previous description the name taxicab geometry arises. The taxicab geometry is appropriate to discuss out during the undergraduate study in the form of essays, seminar works and diploma thesis as it is described in [7] and [9]. Second, the taxicab geometry is interesting for theoretical geometry study, too. It can be analyzed by synthetic approach (introduced by David Hilbert), or by metric approach ( described by George David Birkhoff). Mentioned approaches are described and discussed in [6]. There is the third approach in geometry using abstract groups and group theory. This approach was introduced by Felix Klein and Arthur Cayley. They claimed that geometry had to be studied through acting the group of motions on the given set. Further, some propositions about ellipses in the taxicab geometry are proved. Third, the practical value of the taxicab geometry is its wide application in (urban) transportation problems, city planning and so on. This application has been described in [10].Taxicab geometrija jedna je od neeuklidskih geometrija. Tu je geometriju još prije 100 godina razmatrao Hermann Minkowski (Gesammelte Abhandlungen), a od tada doživljavala je periode marginalizacije i gotovo zaborava, ali i periode velikog zanimanja i široke primjene. Danas se može pronaći čitav spektar upotrebe i primjene taxicab geometrije. Za to postoji više razloga. Prvo, taxicab geometrija bliska je euklidskoj geometriji i lagana za razumijevanje. Može se promatrati kao metrički sustav u kojem točke korespondiraju križanjima ulica u zamišljenom gradu gdje ulice idu samo horizontalno i vertikalno i nema jednosmjernih ulica (odatle i naziv taxicab geometrija). Kao takva pogodna je za izučavanje na dodiplomskom studiju u obliku eseja, seminarskih radova i diplomskih radova (kao što je opisano u [7] i [9]). Drugo, taxicab geometrija zanimljiva je za izučavanje i sa stanovišta teorijske geometrije. Moguće ju je opisati upotrebom sintetičkog pristupa (koji je uveo David Hilbert), ali i metričkim pristupom (za koji je zaslužan George David Birkhoff). Oba ova pristupa pojašnjena su i upotrebljena za uvođenje taxicab geometrije u [6]. Postoji i treći pristup u geometriji preko apstraktne algebre i teorije grupa koji su uveli Felix Klein i Arthur Cayley koji tvrdi da se geometrija treba proučavati preko djelovanja grupe gibanja na zadani skup. Nadalje, dokazat ćemo neke poučke o elipsi u taxicab geometriji. Treće, praktična je vrijednost taxicab geometrije njezina široka primjenjivost na stvarne (urbane) probleme transporta, planiranja gradova itd. O tim primjena govori se npr. u [10]

Exploring the grammar of perception A case study using data from Russian

In this paper, I pursue the distributional hypothesis that the meaning of a word is derived from the linguistic contexts in which it occurs and apply it to verbs of perception. Differently from NLP implementations of the distributional hypothesis, I explicitly limit the range of variables to the grammatical domain and chart the way in which verbs of Vision, Hearing and Touch are used, morphologically and syntactically, in a representative sample of corpus data. Some aspects of experience are so central and pervasive that reference to them has grammaticalized (Divjak 2010; see also Janda & Lyashevskaya 2011; Newman 2008). The aim is, firstly, to determine to which extent a verb’s grammatical context alone allows us to classify utterances according to the perception type, and, secondly, to chart the similarities and differences in the verbs’ preference for morphological markers and syntactic constructions. If contexts are highly specialized, language structure, as it is witnessed in use, could assist sensory impaired speakers in building up viable representations of concepts, even if sensory experience is lacking. If, in addition, similarities between certain sensory perception verbs are high, sensory impaired speakers could use these similarities to perform analogical mapping across senses and ground concepts relating to the impaired sense in a cognate sensory experience. The findings are relevant for concept acquisition and representation in general and for concept acquisition and representation in sensory impaired populations, such as the blind, in particular

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]

PRILOG ISTRAŽIVANJU REFLEKSIJA RIJECI »NUMERUS« U INFORMATIČKOM NAZIVLJU NJEMAČKOG JEZIKA

U radu se iznose rezultati autorova istraživanja o refleksiji riječi »numerus« u informatičkom nazivlju. Uspoređuju se stanje i normiranje tog nazivlja u niemačkom i hrvatskom ili srpskom jeziku. Dok je u njemačkom jeziku ustanovliena brojnost izraza izvedenih iz korijena »numer«, u hrvatskom ili srpskom jeziku može se još uvijek govoriti o skromnosti nazivlja tog porijekla. Na kraju autor ukazuje na potrebu timskog rada na informatičkom nazivlju i normiranja radi njegove jednoznačne primjene

Social network analysis of study environment

Student working environment influences student learning and achievement level. In this respect social aspects of students’ formal and non-formal learning play special role in learning environment. The main research problem of this paper is to find out if students\u27 academic performance influences their position in different students\u27 social networks. Further, there is a need to identify other predictors of this position. In the process of problem solving we use the Social Network Analysis (SNA) that is based on the data we collected from the students at the Faculty of Organization and Informatics, University of Zagreb. There are two data samples: in the basic sample N=27 and in the extended sample N=52. We collected data on social-demographic position, academic performance, learning and motivation styles, student status (full-time/part-time), attitudes towards individual and teamwork as well as informal cooperation. Afterwards five different networks (exchange of learning materials, teamwork, informal communication, basic and aggregated social network) were constructed. These networks were analyzed with different metrics and the most important were betweenness, closeness and degree centrality. The main result is, firstly, that the position in a social network cannot be forecast only by academic success and, secondly, that part-time students tend to form separate groups that are poorly connected with full-time students. In general, position of a student in social networks in study environment can influence student learning as well as her/his future employability and therefore it is worthwhile to be investigated

A learning perspective on individual differences in skilled reading: Exploring and exploiting orthographic and semantic discrimination cues

The goal of the present study is to understand the role orthographic and semantic information play in the behaviour of skilled readers. Reading latencies from a self-paced sentence reading experiment in which Russian near-synonymous verbs were manipulated appear well-predicted by a combination of bottom-up sub-lexical letter triplets (trigraphs) and top-down semantic generalizations, modelled using the Naive Discrimination Learner. The results reveal a complex interplay of bottom-up and top-down support from orthography and semantics to the target verbs, whereby activations from orthography only are modulated by individual differences. Using performance on a serial reaction time task for a novel operationalization of the mental speed hypothesis, we explain the observed individual differences in reading behaviour in terms of the exploration/exploitation hypothesis from Reinforcement Learning, where initially slower and more variable behaviour leads to better performance overall

Laypersons' perception of common cold and influenza prevention : a qualitative study in Austria, Belgium and Croatia

Background: Common cold and influenza result in an increased number of primary care consultations, significant work/school absences and cause a socio-economic burden. Laypeople's perceptions and knowledge regarding common cold and influenza prevention is poorly understood and under-researched. Objectives: Our study explores laypeople's knowledge of prevention of common cold and influenza across three European countries. Furthermore, it investigates if there is any distinction between prevention activities focussing on reasons impacting the attitude towards influenza vaccination as well as investigating cross-country variation. Methods: In total, 85 semi-structured individual interviews were performed across three European countries (Austria n = 31, Belgium n = 30, Croatia n = 24). Qualitative thematic content analysis was performed. Results: Most participants across all three countries made no distinction between the prevention of the common cold and influenza and referenced the same preventative measures for both conditions. They mainly expressed negative attitudes towards influenza vaccination possibly effective but only intended for high-risk groups (bedridden/older people, chronic patients or health workers). There were very few cross-country differences in results. Conclusion: The perception of health risk of contracting influenza and a primary healthcare physicians' recommendation played an important role in shaping participants' decisions towards vaccination. Primary healthcare physicians are invited to assess and if necessary adjust inappropriate prevention behaviour through their everyday patient consultations as well as add to the knowledge about influenza severity and influenza vaccination benefits to their patients
