Sink or swim : on associative structuring in longer Latvian folksongs
The oral tradition of Latvian lyrical folksongs, or dainas, began to be recorded at the beginning of the last century and is currently available in both the printed and the electronic media. These songs are in octosyllabic blank verse divided by a caesura, and the overwhelming majority of them follow a trochaic meter, the rest being dactylic.1 The classical source is the collection of 217,996 text versions classified and published by Krisjanis Barons (Barons and Visendorfs 1894-1915), in which a "song" is typically presented as a brief, epigrammatic quatrain unit, with barely 10[percent] of the material consisting of texts longer than eight lines. The same system of text identification was adopted in the supplement to this corpus published by Peateris Smits (1936-39) and in the Daina Data Base (1982), a transcription of a 12-volume collection incorporating the essential elements of both these primary sources (Svabe et al. 1952-56).Not
UNIVERSITY STUDENTS’ GROWTH GOALS, OPPORTUNITIES FOR GOAL FULFILLMENT, AND PERCEIVED UNIVERSITY AND MESOSYSTEM SUPPORT
This study assessed the relationship between students’ growth goals and perceived opportunities to achieve these goals in Latvia and the perceived support from the university and the mesosystem. Socialization models emphasize that the setting of personal goals occurs in continuous interaction with the sociocultural context, which includes perceived opportunities to achieve these goals and the interpersonal environment. Both – perceived support from close people (mesosystems) and perceived support from the university – are significant for students. The study involved 432 university students between 18 and 49. We have assessed the extent to which students’ goals regarding education, work, and personal growth are predicted by perceived opportunities to achieve these goals in Latvia and by the perceived support from parents, relatives, friends, classmates, teachers, and the university as an institution. The results of structural equation modeling revealed that personal growth goals are positively predicted by all three elements - the perceived opportunities to achieve these goals and the perceived academic and mesosystem support. The support of the classmates was connected to the support of the mesosystem that indicates the importance of friendly relations among students. Students’ growth goals were the most closely associated with the perceived support in their specific environment – the university. In general, the results confirm the complex interaction of personal growth goals with the social and cultural environment in particular circumstances
THE EFFECTS OF MYOFASCIAL SELF-RELEASE METHOD AND TOOL APPLICATION ON ATHLETE STRENGTH INDICATORS IN TIBIA EXTENSOR MUSCLES IN FITNESS
The aim of the present study was to analyse the effectiveness of myofascial self-release methods and the use of the tool in the development of strength indicators in the tibia extensor muscles. Instrumental assessment of muscle function was performed on a REV 9000, Technogymᴿ, Italy. The subjects of our study were twenty healthy fitness athletes aged between 20 and 23 years. A set of strength exercises was developed, consisting of 10 exercises focused on increasing the muscle strength of tibia extensor muscles. For the experimental group self-massage with a roller was applied. When applying strength-development exercises with a set of self-release, the dynamics of maximum strength results are as follows: the force balance of the dominant and the non-dominant leg in the control group before (p=0.001) and after (p=0.02) the experiment, and in the experimental group before (p=0.01) and after (p=0.02) the experiment remained unchanged – no significant changes were observed in the results between the groups; - positive dynamics in strength changes were observed for the dominant leg between the control group (p=0.08) and the experimental group (p=0.37) before and after the experiment. The positive increase in the results is in favour of the experimental group, although there are no significant statistical differences in the results of the control group. On the other hand, no differences in the strength dynamics of the non-dominant leg were found.
Engineering design of the EURISOL multi-MW spallation target
The European Isotope Separation On-Line Radioactive Ion Beam project (EURISOL) is set to design the 'next-generation' European Isotope Separation On-Line (ISOL) Radioactive Ion Beam (RIB) facility. It will extend and amplify current research on nuclear physics, nuclear astrophysics and fundamental interactions beyond the year 2010. In EURISOL, four target stations are foreseen, three direct targets of approximately 100 kW of beam power and one multi-MW target assembly, all driven by a high-power particle accelerator. In this high power target station, high-intensity RIBs of neutron-rich isotopes will be obtained by inducing fission in several actinide targets surrounding a liquid metal spallation neutron source. This article summarises the work carried out within Task 2 of the EURISOL Design Study, with special attention to the coupled neutronics of the mercury proton-to-neutron converter and the fission targets. The overall performance of the facility, which will sustain fast neutron fluxes of the order of 1014 n/cm2/s, is evaluated, together with the production of radionuclides in the actinide targets, showing that the targeted 1015 fissions/s can be achieved. Some of the greatest challenges in the design of high power spallation sources are the high power densities, entailing large structural stresses, and the heat removal, requiring detailed thermo-hydraulic calculations. The use of a thin martensitic steel beam-window and a well-controlled mercury flow has been shown to reduce the von-Misses stress in the former below the 200 MPa limit, with reasonable maximum flow rates of ~6 m/s. Alternatively, a windowless target configuration has been proposed, based on a liquid mercury transverse film. With this design, higher power densities and fission rates may be achieved, avoiding the technical difficulties related to the beam window. Experimentally, several tests have been performed at IPUL (Riga, Latvia) in order to study the stability of the liquid metal flow and validate the mercury loop design
The integral equation approach to kinematic dynamo theory and its application to dynamo experiments in cylindrical geometry
The conventional magnetic induction equation that governs hydromagnetic
dynamo action is transformed into an equivalent integral equation system. An
advantage of this approach is that the computational domain is restricted to
the region occupied by the electrically conducting fluid and to its boundary.
This integral equation approach is first employed to simulate kinematic dynamos
excited by Beltrami-like flows in a finite cylinder. The impact of externally
added layers around the cylinder on the onset of dynamo actions is
investigated. Then it is applied to simulate dynamo experiments within
cylindrical geometry including the von Karman sodium (VKS) experiment and the
Riga dynamo experiment. A modified version of this approach is utilized to
investigate magnetic induction effects under the influence of externally
applied magnetic fields which is also important to measure the proximity of a
given dynamo facility to the self-excitation threshold.Comment: 22 pages, 14 figure
Musiknedladdning och attityder
Titel: Musiknedladdning och attityder – En kvalitativ intervjustudie
Författare: Peter Freibergs och Linda Solberg
Handled.: Annika Bergström
Kurs: Fördjupningskurs VT-07
Syfte: Vårt syfte att undersöka ungdomars/unga vuxnas attityder till olaglig
nedladdning av musik och koppla samman det med livsstil och beteende.
Metod: Kvalitativ intervjustudie.
Material: Tio stycken respondenter
Huvudres.: Fyra av tio respondenter hade övervägande positiva attityder. Tre av tio
hade övervägande negativa attityder och tre av tio hade blandade attityder.
Lättillgängligheten och att det är gratis är viktiga argument för de positiva. Man kan provlyssna och upptäcka ny musik samt få tag på sådant som annars kan vara svårt att få tag på. Ur artisters synvinkel ses det som positivt att de kan nå ut med sin musik .
Negativa argument är att man stjäl någons musik, vilket i slutändan gör att artisterna inte har råd att producera mer musik och att skivaffärer då också försvinner. De pekar även på lagen som ger stränga straff.
Sambandet mellan attityd och beteende ser olika ut för olika personer. Personer med övervägande positiva attityder gentemot fildelning upplever ingen kognitiv dissonans (tankekonflikt eller obehag) då deras
attityder och beteenden överensstämmer. Personer med övervägande negativa attityder gentemot fildelning upplever, enligt teorin, kognitiv dissonans då deras attityder inte överensstämmer med deras beteende.
De tycker att det är fel att ladda ned, men gör det ändå. Denna obalans reducerar de genom att ändra sitt beteende efter attityden och laddar ned mindre. På så sätt väger de upp obalansen och det känns mer rätt att
ladda ned. Andra reducerar obalansen genom att ändra sin attityd även om det inte är lika utmärkande. Det gör de genom att framföra argument som gör att det känns bättre och inte lika fel för dem att ladda ned.
Livsstil är en viktig grund för vilka attityder en person har. Vi har sett fall där personer med liknande livsstil har samma attityd. Samtidigt har vi sett fall där de med liknande livsstil inte alls är överens.
Vi har kunnat utläsa olika sociala världar vilka kan skapas av en intressegemenskap som att spela i band eller att leva i en parrelation

Influence of Multimodal Priming on Customer Behaviour
Nav salīdzinošo pētījumu par patērētāju uzvedības praimošanu audiālajā, vizuālajā, semantiskajā modalitātē. Pētījuma mērķis bija noskaidrot, vai, praimojot patērētājus caur dažādām modalitātēm, tas ietekmē viņu pirkšanas uzvedību. Datu ievākšanai tika īstenoti trīs pētījumi: pilotpētījums (piedalījās 125 respondenti) eksperiments Nr. 1 (203 respondenti) un eksperiments Nr. 2 (56 respondenti). Eksperimentos tika manipulēts ar četriem praimiem trīs modalitātēs, ar un bez iejaukšanās uzdevuma. Neviens no izvēlētajiem praimiem neietekmēja patērētāju uzvedību. Tomēr vāju ietekmi uzrādīja iejaukšanās uzdevums. Netika gūts apstiprinājums, ka iejaukšanās uzdevums mediē praimošanu, tas iedarbojās neatkarīgi. Rezultāti norāda, ka patērētāju uzvedību vienkāršs praima stimuls neietekmē vai ietekmē ļoti nelielā mērā. Atslēgas vārdi: praims, praimings, patērētāju uzvedība, dinamisko sistēmu modelis.There are no comparative studies on the priming of consumer behavior in audio, visual, and semantic modality. The aim of the study was to find out whether the priming of consumers through different modalities affects their buying behavior. Three studies were carried out to collect data: a pilot study (participated 125 respondents) experiment No. 1 (203 respondents) and experiment No. 2 (56 respondents). The experiments were manipulated with four primes in three modalities, with and without intervening task. None of the selected primes affected consumer behavior. However, the intervening task showed a weak effect. There was no evidence that the intervening task mediated priming, it acted independently. The results show that consumer behavior by a simple prime stimulus is not affected or is affected to a very small extent. Keywords: prime, priming, consumer behavior, the dynamic system model
