Starptautisko privāttiesību attīstība Latvijā

2016

Maģistra darbā “Starptautisko privāttiesību attīstība Latvijā”, izmantojot vairākas zinātniskās pētniecības metodes, analizēta starptautisko privāttiesību, galvenokārt kolīziju normu, attīstība Latvijā, vērtējot nacionālā regulējuma mijiedarbību ar starptautisko un Eiropas Savienības regulējumu. Maģistra darba gaitā secināts, ka, lai gan ir notikusi starptautisko privāttiesību attīstību, tomēr Civillikumā ietverto kolīziju normu attīstība Latvijā gandrīz nav notikusi, pamatojoties uz arvien pieaugošo Eiropas Savienības regulējuma ietekmi. Tomēr, neskatoties uz Eiropas Savienības regulējumu, būtu nepieciešams atkārtoti aktualizēt jautājumu par starptautisko privāttiesību likuma izstrādi Latv…

Grāmatvedības politikas analīze un pilnveidošana SIA “Silja”

2017

Bakalaura darba mērķis ir uz grāmatvedības politikas prasību un teorētisko nosacījuma pamata veikt SIA “Silja” grāmatvedības politikas analīzi, atklāt nepilnības un izstrādāt priekšlikumus grāmatvedības politikas pilnveidošanai. Pirmajā nodaļā tiek apskatīti grāmatvedības politikas veidošanas principi un to regulējošā likumdošana, lai darba praktiskajā daļā varētu analizēt SIA “Silja” īstenoto grāmatvedības politiku. Otrajā nodaļā tiek analizēta uzņēmuma SIA “Silja” esošā grāmatvedības politika un tās īstenošana, veicot uzņēmuma grāmatvedības politikas dokumentu novērtēšanu, lai varētu izstrādāt priekšlikumus grāmatvedības politikas pilnveidošanai, kā arī izpētīts SIA “Silja” grāmatvedības …

High order normal form construction near the elliptic orbit of the Sitnikov problem

2011

We consider the Sitnikov problem; from the equations of motion we derive the approximate Hamiltonian flow. Then, we introduce suitable action–angle variables in order to construct a high order normal form of the Hamiltonian. We introduce Birkhoff Cartesian coordinates near the elliptic orbit and we analyze the behavior of the remainder of the normal form. Finally, we derive a kind of local stability estimate in the vicinity of the periodic orbit for exponentially long times using the normal form up to 40th order in Cartesian coordinates.

Non-Gaussian Distribution for Var Calculation: an Assessment for the Italian Market

2001

Abstract In this paper we compare different approaches to computing VaR (Value-at-Risk) for heavy tailed return series. Using data from the Italian market, we show that almost all the return series present statistically significant skewness and kurtosis. We implement (i) the stable models proposed by Rachev et al . (2000), (ii) an alternative to the Gaussian distributions based on a Generalized Error Distribution and (iii) a non-parametric model proposed by Li (1999). All the models are then submitted to backtest on out-of-sample data in order to assess their forecasting power. We observe that when the percentiles are low, all the models tested produce results that are dominant compared to …

Los cursos en línea, masivos y abiertos en educación superior: análisis para la enseñanza de las NIIF

2016

Esta tesis doctoral se propone explorar en el campo contable, específicamente en la enseñanza de las Normas Internacionales de Información Financiera (NIIF) una de las formas más recientes de aplicación tecnológica en educación, como son los Massive Open Online Courses (MOOC). Modalidad educativa que, en medio de importantes debates educativos, ha sido considerada como apoyo al aprendizaje a lo largo de la vida y una forma de innovación en la educación. La tesis está estructurada en tres partes: la primera, conformada por 2 capítulos que constituyen el marco teórico de la tesis. La segunda parte tiene 5 capítulos que corresponden a los estudios empíricos. Finalmente la tercera parte se comp…

The distribution of Rare Earth Elements discriminates the growth substrate of Vitis vinifera L.

2021

Sustainable agricultural, food-related strategies and geographic traceability require understanding of the plant physiological response to stress potentially generated by contaminated soils. Here, we have investigated the effect of contaminated substrate on growth of Vitis vinifera L. plants analysing the distribution of full Rare Earth Elements (REE) spectra in different parts of the plant. Experiments were carried out using pristine plants growing in a handmade substrate (blank experiment) and in REE artificially-enriched soil (spiked experiment). Our results show that both plant mass and REE amount in leaves are not influenced by the substrate enrichment while roots are by one-order of m…

Axons take a dive

2014

In the walls of the lateral ventricles of the adult mammalian brain, neural stem cells (NSCs) and ependymal (E1) cells share the apical surface of the ventricular-subventricular zone (V-SVZ). In a recent article, we show that supraependymal serotonergic (5HT) axons originating from the raphe nuclei in mice form an extensive plexus on the walls of the lateral ventricles where they contact E1 cells and NSCs. Here we further characterize the contacts between 5HT supraependymal axons and E1 cells in mice, and show that suprependymal axons tightly associated to E1 cells are also present in the walls of the human lateral ventricles. These observations raise interesting questions about the functio…

Biciliated ependymal cell proliferation contributes to spinal cord growth

2012

Two neurogenic regions have been described in the adult brain, the lateral ventricle subventricular zone and the dentate gyrus subgranular zone. It has been suggested that neural stem cells also line the central canal of the adult spinal cord. Using transmission and scanning electron microscopy and immunostaining, we describe here the organization and cell types of the central canal epithelium in adult mice. The identity of dividing cells was determined by 3D ultrastructural reconstructions of [3H]thymidine-labeled cells and confocal analysis of bromodeoxyuridine labeling. The most common cell type lining the central canal had two long motile (9+2) cilia and was vimentin+, CD24+, FoxJ1+, So…
