COMMUTING PATTERNS IN RIGA AGGLOMERATION: EVIDENCE FROM A SURVEY ANALYSIS OF YOUTH
2021
In the last ten years the evident changes of settlement patterns through suburban growth near to capital city of Latvia occurred. Increase of distance between home and routine activity places as well as changes of public transport and rapid increase of car ownership initiated significant changes in commuting patterns of inhabitants living outside of Riga. Although the commuting from suburban area to Riga is recently broadly studied, however these researches focused primarily on able-bodied population leaving behind school-age children and young people. The aim of this study is to analyse commuting patterns of young people aged 12 to 17 moving from outskirts of Riga to school located in Riga…
El campo mediático-digital y la diferenciación social
2021
La digitalización de la sociedad ha abierto nuevos horizontes de investigación a la disciplina sociológica. Sin embargo, los análisis realizados en los últimos años tienden a dejar en un lugar secundario las referencias clásicas de la sociología. Este trabajo pretende mostrar la viabilidad del análisis de la cultura digital desde la perspectiva de los campos sociales de Pierre Bourdieu. Las herramientas teóricas y metodológicas que proporciona el autor francés pueden ser muy útiles para evitar tanto el utopismo digital como los análisis críticos influidos por perspectivas neomarxistas, centrados mayoritariamente en las formas de explotación económica. La teoría de los campos sociales puede …
Tunable source of infrared pulses in gas-filled hollow core capillary
2020
International audience; We report a tunable source that generates pulses in the infrared from an optical parametric amplification in a gas-filled hollow core capillary based on four-wave mixing process, in which the phase matching strongly depends on the gas pressure and the pump. In our case, we have generated pulses from 1 to 1.6 m in the sub-µJ level together with a parametric amplification in the visible.
The embryo-placental CD15-positive "vasculogenic zones" as a source of propranolol-sensitive pediatric vascular tumors.
2015
Abstract Objective Propranolol-induced involution is a unique biological feature of some pediatric vascular tumors, for instance infantile hemangioma (IH), cerebral cavernoma or chorioangioma. Currently, the cellular origin of these distinct tumors is unclear. In this study, we tested the hypothesis that propranolol-responsive vascular tumors are derived from common vessel-forming CD15 + progenitor cells which occur in early gestation. The aim of this study was to identify the tumor-relevant CD15 + progenitors at the early stages of embryo-placental development. Materials and methods Human embryo-placental units of 4–8 weeks gestation and pediatric vascular tumors were tested for expression…
Towards a theory of transnational academic capitalism
2013
This article draws attention to the relative lack of theoretically and methodologically elaborated approaches to understand and explain the complex relations between transnationalization of higher education and globalization seen especially from the point of view of global capitalism. The main aim of this article is to contribute to the construction of a theory of transnational academic capitalism (TAC). A theory of TAC argues that those networks, practices and activities that are blurring the boundaries between higher education, markets and states are increasingly becoming transnational without supposing that this transformation implies that local and national levels are insignificant in s…
When intentions turn into action: pathways to successful firm performance
2021
Entrepreneurship brings wealth to nations and contributes to their economic growth. People can take many paths to become entrepreneurs. Some join the family business, whilst others are born entrepreneurs, letting their innate intuition lead them into firm creation. For many, though, being able to learn and acquire the right skills is critical for a successful career as an entrepreneur. Like other human capital factors, entrepreneurial skills can be acquired. In today’s fast-changing society, it is of utmost importance for entrepreneurs not only to gain these skills but also to be surrounded by a supportive environment that will (1) guide them in the creation of their business idea and (2) h…

2014
IZGLĪTĪBAS PRIVĀTĀS UN SOCIĀLĀS ATDEVES NOVĒRTĒJUMS LATVIJĀ Anotācija Promocijas darba mērķis ir novērtēt izglītības ietekmi uz darba samaksu un darba produktivitāti indivīda un sabiedrības līmenī Latvijā, kā arī izstrādāt priekšlikumus izglītības nozīmes paaugstināšanai un atdeves novērtējuma lietošanai. Lai novērtētu izglītības privāto atdevi, tiek izmantota Mincera ienākumu funkcija, kā arī profesora E. de la Fuentes metodoloģija. Novērtējot sociālo atdevi, autore aprēķināja vīriešu un sieviešu (ar augstāko izglītību) cilvēkkapitālu laika posmā no 2000. līdz 2010. gadam un iegūtos rezultātus lietoja ražošanas funkcijā, aprēķinot izglītības ietekmi uz darba produktivitāti. Autore aprēķinā…

Combination of supported liquid membrane and solid-phase extraction for sample pretreatment of triazine herbicides in juice prior to capillary electr…
2002
A possibility of a combination of supported liquid membrane (SLM) and solid-phase extraction (SPE) for the determination of atrazine at microgram level in different type of fruit juices is presented. In comparison to SPE extraction from juice samples, the application of SLM-SPE enrichment provides much cleaner extracts and the possibility of lowering the limit of detection as low as 30 microg/l. However, it was also shown that by appropriate manipulation of SLM extraction conditions mainly flow-rate of donor phase and volume ratio between donor and acceptor phase, the level of detection can be further decreased to 10 microg/l. The results suggest that the application of SLM extraction prior…
