JVLMA bibliotēkas Fotogrāfiju un attēlu datubāzes izstrāde: satura aspekts

2017

Bakalaura darbā pētīta Jāzepa Vītola Latvijas Mūzikas akadēmijas bibliotēkas Fotogrāfiju un attēlu datubāzes kvalitāte satura aspektā. Vairākus gadus datubāze nav papildināta vai apsekota, trūkst informācijas par tās izstrādes principiem. Pētījuma mērķis ir izpētīt esošo situāciju, lai uzlabotu datubāzes kvalitāti nākotnē. Darba teorētisko bāzi veido pragmatisma pieeja, “Holistiskais DB novērtēšanas modelis” un digitālo kolekciju izstrādes vadlīniju ieteikumi satura atlasē un metadatu pievienošanā. Izmantojot interviju un kontentanalīzi, noskaidroti satura atlases kritēriji un novērtēti aprakstošie metadati. Rezultāti atklāj, ka atlasē svarīga ir objektu saistība ar Mūzikas akadēmiju, savuk…

Search for supersymmetry in events with photons, bottom quarks, and missing transverse momentum in proton-proton collisions at a centre-of-mass energ…

2013

A search has been performed for the experimental signature of an isolated photon with high transverse momentum, at least one jet identified as originating from a bottom quark, and high missing transverse momentum. Such a final state may originate from supersymmetric models with gauge-mediated supersymmetry breaking in events in which one of a pair of higgsino-like neutralinos decays into a photon and a gravitino while the other decays into a Higgs boson and a gravitino. The search is performed using the full dataset of 7 TeV proton–proton collisions recorded with the ATLAS detector at the LHC in 2011, corresponding to an integrated luminosity of 4.7 fb−1. A total of 7 candidate events are o…

Studējošo jauniešu grāmatu izvēles faktori

2019

Maģistra darba „Studējošo jauniešu grāmatu izvēles faktori” pētījuma mērķis ir noskaidrot, kādi faktori un cik lielā mērā ietekmē studējošo jauniešu drukāto grāmatu izvēli gan iegādājoties, gan aizņemoties tās. Pētījums tiek balstīts uz filozofijas teoriju – fenomenoloģiju un Švarca vērtību modeli. Fenomenoloģija kā filozofijas virziens skaidro, cilvēka apziņā esošos fenomenus, savukārt, Švarca vērtību modelis skaidro, kā veidojas cilvēka vērtību pasaule un kā tā ietekmē katru indivīdu. Izmantojot Delfu metodi un intervēšanu, pētījuma rezultātā tika noskaidrots, ka noteicošie faktori, kas ietekmē studējošo jauniešu grāmatu izvēli ir tēma, lasīšanas mērķis, lasīšanas vide, grāmatas cena un a…

Atlas of the Baltic languages: from idea to pilot project

2015

Atl as of the B a ltic l a ngu a ge s : from idea to pilot project Dialectologists from Latvian Language Institute of the University of Latvia and the Department of Language History and Dialectology of the Institute of the Lithuanian Language, have developed a proposal for a joint project entitled, The Atlas of the Baltic Languages, which is intended to demonstrate the close kinship of these two Baltic languages. A pilot project, supported by a grant from the University of Latvia and Directorate for the Millenium of Lithuania has been carried out between 2006 and 2008 to determine what the form and eventual content of such an atlas might be. In 2009 a summary of work carried out on the pilo…

Search for pair production of first or second generation leptoquarks in proton-proton collisions at sqrt(s)=7 TeV using the ATLAS detector at the LHC

2011

This paper describes searches for the pair production of first or second generation scalar leptoquarks using 35  pb−1 of proton-proton collision data recorded by the ATLAS detector at √s=7  TeV. Leptoquarks are searched in events with two oppositely-charged muons or electrons and at least two jets, and in events with one muon or electron, missing transverse momentum and at least two jets. After event selection, the observed yields are consistent with the predicted backgrounds. Leptoquark production is excluded at the 95% CL for masses MLQ<376 (319) GeV and MLQ<422 (362) GeV for first and second generation scalar leptoquarks, respectively, when assuming the branching fraction of a leptoquark…

Direct and oblique approaches to the craniovertebral junction: Nuances of microsurgical and endoscope-assisted techniques along with a review of the …

2017

Purpose: The aim of this review is to provide an update of the technical nuances of microsurgical and endoscopic-assisted approaches to the craniovertebral junction (transnasal, transoral, and transcervical), and to report on the available clinical results in order to identify the best strategy. Methods: A nonsystematic update of the reviews and reporting on the anatomical and clinical results of endoscopic-assisted and microsurgical approaches to the craniovertebral junction (CVJ) was performed. Results: Pure endonasal and cervical endoscopic approaches still have some disadvantages, including their steep learning curves and their deeper surgical fields. Endoscopically assisted transoral s…
