Proaktivitātes un darba stresa saistība ar alkohola lietošanu ēdināšanas jomas darbiniekiem

2022

Maģistra darba mērķis ir teorētiski analizēt literatūru, kas izskaidro darba stresu, proaktīvas personības iezīmes konstruktu saistībā ar alkohola lietošanas paradumiem ēdināšanas jomas darbiniekiem, un uz tās pamata izvirzīt un pārbaudīt pētījuma hipotēzes. Kvantitatīvi izpētīt saistības starp alkohola lietošanas paradumiem un proaktīvas personības iezīmēm saistībā ar darba stresu. Darba ietvaros tika pētīti un apkopoti tādi zinātniskie raksti un pētījumi, kas apskata stresu, darba stresu, proaktīvas personības konstruktu, stresa pārvarēšanas stratēģijas un alkohola lietošanas paradumus, kā arī apkalpošanas un it īpaši, ēdināšanās jomas, profesijas specifiskās īpatnības. Aptaujai tika izma…

Experimental Investigation on Stiffness and Strength of Single-Lap Z-Pinned Joints in a Laminated CFRP Stress-Ribbon Strip

2016

Carbon fiber-reinforced polymer (carbon-polymer) is an advanced lightweight composite material with high strength and excellent resistance to corrosion and fatigue. Over the past decades, application of fiber-reinforced polymers has been spread from the aerospace to other branches of industry such as automobile and civil engineering. Unidirectional carbon-polymers have a high potential for replacing steel in tensile members. Recently, the first carbonpolymer stress-ribbon bridge has been constructed in Germany. The non-laminated strip-loop carbon-polymer thin strips were used as the load bearing components in this bridge. In comparison with the laminated components, the applied cables are c…

Projektu pārskats kā žanrs

2018

Projektu vadība ir iefiltrējusies daudzās biznesa jomās, tomēr projektu pārskats kā žanrs nav bijis pilnvērtīgi izpētīts. Šī pētījuma mērķis bija izpētīt projektu pārskatu žanru veicot retorisko posmu un soļu analīzi un apskatot laika aspektu formas katrā retoriskajā posmā. Lai sasniegtu izvirzīto mērķi, tika veikta žanra analīze korpusam, kurš sastāvēja no 50 nejauši izvēlētiem projektu pārskatiem no Kopienas Pētniecības un attīstības informācijas dienesta (Community Research and Development Informative Service) (CORDIS) datubāzes. Empīriskās analīzes rezultāti liecināja, ka projektu pārskatu retoriskā uzbūve sastāv no četriem retoriskajiem posmiem un katrs retoriskais posms ir izpildīts a…

Karjeras mērķu kvalitātes un satura un proaktīvas karjeras uzvedības atšķirības dažādu kursu un līmeņu studentiem

2021

Maģistra darba mērķis bija noskaidrot, vai karjeras mērķu kvalitātei ir saistības ar proaktīvu karjeras uzvedību un kā karjeras mērķu saturs un kvalitāte un proaktīva karjeras uzvedība atšķiras dažādu nozaru, līmeņu un kursu studentiem. Pētījumā piedalījās 168 dažādu nozaru, līmeņu un kursu studenti. Izmantotas 3 aptaujas, kas adaptētas latviešu valodā darba ietvaros: Karjeras mērķu kvalitātes aptauja (Career Goals Quality, Greco, 2016), Karjeras mērķu aptauja (Career Goals, Seibert, Kraimer, Holtom & Pierotti, 2013) un Proaktīvas karjeras uzvedības aptauja (Proactive Career Behavior Measure, Strauss, Griffin & Parker, 2012). Pētījumā noskaidrots, ka karjeras mērķu kvalitātei un proaktīvai …

Supraclavicular approach is an easy and safe method of subclavian vein catheterization even in mechanically ventilated patients: Analysis of 370 atte…

2009

BACKGROUND: Central venous catheters are commonly inserted for hemodynamic monitoring, volume monitoring, administration of medications, long-term total parenteral nutrition, access for renal replacement therapy, cardiopulmonary resuscitation, and difficult peripheral catheterization. The primary outcome of this study was to define venipuncture, catheterization and entire procedure success rates, and finally complication rate of subclavian venous catheterization via the supraclavicular approach with special focus on mechanically ventilated patients. The secondary outcome was to potentially make recommendations regarding this technique of central venous catheterization in mechanically ventil…

Discussing Mathematical Learning and Mathematical Praxeologies from a Subject Scientific Perspective

2018

International audience; This programmatic contribution discusses the link between concepts from Anthropological Theory of Didactics (ATD) and the “subject-scientific point of view” according to Holzkamp (1985, 1993). The main common concern of ATD and the subject-scientific approach is to conceptualize and analyse “objects” like “institutionalized mathematical knowledge” and “university” not as conditions that cause reactions but essentially as meanings in the sense of generalized societal reified action possibilities. The link of both approaches is illustrated by the issue of “real numbers” in the transition from school to university: Hypotheses are derived for further actual-empirical res…

"You've got the color, but you dont't have the shades" : primary education CLIL teachers' identity negotiation within the Finnish context

2018

This dissertation explores how professional identity is experienced by teachers in Content and Language Integrated Learning (CLIL) instruction. In particular, it addresses professional identity in relation to two immediate contexts of teacher activity, i.e. that of the classroom and that of the collegial community. In addition to exploring how these two sides of the professional self give rise to a broader understanding of professional identity, this dissertation also explores aspects of professional agency and the negotiation of emotions in their work. The dissertation is founded on fourteen interviews with Finnish kindergarten and primary education teachers doing CLIL. The data were thema…

Classical and reverse substituent effects in meta- and para-substituted nitrobenzene derivatives

2017

Electron-accepting properties of the nitro group were studied in a series of meta- and para-X-substituted nitrobenzene derivatives (X = NMe2, NH2, OH, OMe, CH3, H, F, Cl, CF3, CN, CHO, COMe, CONH2, COOH, COCl, NO2, NO). For this purpose Hammett-like approaches were applied based on quantum chemistry modeling; the B3LYP/6-311++ G(d,p) method was used. The substituent effect (SE) was characterized by the mutually interrelated descriptors: the charge of the substituent active region, cSAR(X), and substituent effect stabilization energy, SESE, as well as substituent constants, σ. Classical SE is realized by dependences of the structural parameters of the nitro group (ONO angle and NO bond lengt…
