Effect ofMicrocystis aeruginosa andNodularia spumigena on survival ofEurytemora affinis and the embryonic and larval development of the Baltic herrin…

2003

Laboratory experiments were carried out to investigate the effect of two strains of Microcystis aeruginosa and a strain of Nodularia spumigena on the survival of Eurytemora affinis (Copepoda) and on the embryonic and larval development of the Baltic spring-spawning herring Clupea harengus membras. The trials were made in water taken from Parnu Bay, at a salinity of 3.7–5.1 psu, a constant temperature (15°C ± 1°C in trials with Eurytemora and herring embryos; 18°C ± 2°C with herring larvae), and an oxygen concentration of 8.8–10.4 ppm. The strains tested had a negative impact on the survival of Eurytemora, as well as on the embryonic development and hatching regime of the Baltic herring. In …

Theoretical Old-Age Pension Benefits and Replacement Rates in the Baltic States: A Retrospective Simulation

2016

Abstract The author presents a comparative analysis of old-age pension systems in Estonia, Latvia and Lithuania using a method of retrospective simulation run on a self-developed model. The model baseline case is a person retiring in December 2014 after 40 years of service with nationwide average salary. Other cases include low and high-earners, funded schemes participants and simulations for modified notional capital valorisation formulae. Three study countries return very dissimilar results, which is caused by differences in their pension systems’ designs. Lack of non-contributory element (basic pension) in Latvia leads to a low degree of progressivity, with inexcusably low pensions to lo…

Human Dietary Intake of Organochlorines from Baltic Herring: Implications of Individual Fish Variability and Fisheries Management

2007

This study examines the extent to which Finnish human dietary intake of organochlorines (PCDD/Fs and PCBs) originating from Northern Baltic herring can be influenced by fisheries management. This was investigated by estimation of human intake using versatile modeling tools (e.g., a herring population model and a bioenergetics model). We used a probabilistic approach to account for the variation in human intake of organochlorines originating from the variation among herring individuals. Our estimates were compared with present precautionary limits and recommendation for use. The results show that present consumption levels and frequencies of herring give a high probability of exceeding recom…

Structural and Static Prerequisites for the Internationalization of Small and Medium – Sized Enterprises in the Baltic States

2014

Abstract The pace and extent of internationalization of small and medium-sized enterprises (SMEs) is the result of the interaction of various factors and preconditions. This article examines one of these prerequisites - the currently established structure of SMEs in the Baltic States. The relationship between the different components of SMEs or the SMEs structure is the slowly varying parameters of the functioning of the economy. However, as an integral element of the economic system, the SME structure affects its development, including internationalization of business. Based on statistical data, the opportunities for small firms to outsource business activities as a perspective form of int…

Sustainability of Pension Systems in the Baltic States

2016

Objective: The objective of the paper is to identify how the concept of sustainability is understood and ensured in the pension systems of Estonia, Latvia and Lithuania; and what implications it brings to the performance of pension schemes. Research Design & Methods: Analysis of various conceptual and methodological approaches to the notion of sustainability of pension systems. Comparative analysis of present pension legislation, as well as preceding stage of pension reforms,   accompanied by a number of numerical models. Findings: The understanding of sustainability is limited by narrow ‘fiscal’ meaning in Latvia, compared to more a multifaceted concept that includes the principle of socia…

Complementary methods assessing short and long-term prey of a marine top predator ‒ Application to the grey seal-fishery conflict in the Baltic Sea.

2019

The growing grey seal (Halichoerus grypus) population in the Baltic Sea has created conflicts with local fisheries, comparable to similar emerging problems worldwide. Adequate information on the foraging habits is a requirement for responsible management of the seal population. We investigated the applicability of available dietary assessment methods by comparing morphological analysis and DNA metabarcoding of gut contents (short-term diet; n = 129/125 seals, respectively), and tissue chemical markers i.e. fatty acid (FA) profiles of blubber and stable isotopes (SIs) of liver and muscle (mid- or long-term diet; n = 108 seals for the FA and SI markers). The methods provided complementary inf…

Baltijas valstu un Somijas tūrisma galamērķa tēla elementi Krievijas auditorijā

2022

Tēlam ir ļoti liela nozīme ceļojuma galamērķa veiksmīgā attīstībā, jo pozitīvs tēls palielina galamērķa atpazīstamību un ietekmē tūristu vēlmi apmeklēt šo galamērķi. Šī pētījuma mērķis ir izpētīt galamērķa tēlu veidojošos elementus, ko Krievijas ceļotāji veido un izplata par Baltijas valstīm (Igauniju, Latviju un Lietuvu) un Somiju. Šajā darbā tēls, tostarp tēla elementi tiek pētīti, izmantojot krievu tūristu atsauksmju, kas publicētas ar ceļošanu saistītās tīmekļa vietnēs, satura analīzi. Darbā tiek atklāti nozīmīgākie galamērķa tēla atribūti, tādi kā, kultūras un dabas resursi, atmosfēra, infrastruktūra, gastronomiskais piedāvājums un nakts dzīve, tīrība, drošība, vietējo iedzīvotāju vies…

Ab initio calculations of the atomic and electronic structure of BaZrO3 (111) surfaces

2013

Abstract The paper presents and discusses the results of calculations of surface relaxations and energetics for the polar (111) surface of BaZrO 3 using a hybrid B3LYP description of exchange and correlation. On the (111) surface, both Zr- and BaO 3 -terminations were analyzed. For both Zr and BaO 3 -terminated BaZrO 3 (111) surface upper layer atoms, with the sole exception of BaO 3 -terminated surface Ba atoms, relax inwards. The Zr-terminated BaZrO 3 (111) surface second layer Ba atoms exhibit the strongest relaxation between all Zr and BaO 3 -terminated BaZrO 3 (111) surface atoms. The calculated surface relaxation energy for Zr-terminated BaZrO 3 (111) surface is almost fifteen times l…

Comparative analysis of the electronic structures of mono- and bi-atomic chains of IV, III–V and II–VI group elements calculated using the DFT LCAO a…

2015

Using the first principle non-relativistic linear combination of atomic orbitals (LCAO) and relativistic linearized augmented cylindrical wave (LACW) methods, the band structure of the covalent and partially ionic ANB8−N single atom width chain is calculated. Both the LCAO and LACW methods show that the chains of C, Si, Ge, Sn, and Pb are metallic. However, there is a great difference between the relativistic and non-relativistic band structures. The π bands crossing the Fermi level are orbitally doubly degenerate in the non-relativistic model. The relativistic LACW calculations demonstrate that the spin and orbital motion of electrons are coupled, thereby splitting the π bands. The spin–or…
