The real exchange rate and competitiveness in Latvia
2006
Freimane, R.
The main aim of the paper is to analyse influence of the real exchange rate on competitiveness of Latvia. Using fundamental equilibrium exchange rate methodology the equilibrium real exchange rate for Latvia is estimated. According the model's results the real exchange rate was overvalued almost during all the reporting period and therefore it could be used as one of the factors influencing competitiveness of Latvia.

2006
Perkumiene, D. | Raupeliene, A.
Family relations have always played and still play an important role in the system of social relations. The family is a primary social cell; if executes the fundamental functions of prolongation of relation, upbringing of young generation, and mutual moral and material support of family members. One of the main stages of family creation from both legal and social points of view is contracting a marriage. The form of entering into a marriage and the definition of family legal relations have been changing in the run of history depending on the culture, church and state relationship, and general philosophy of the particular period of time. The Old Testament of Holy Writ gives information about the marriage. In the ancient times marriage and family were more of a religious institution managed by the church, but as marriage is the roof of every legal establishment - family, relations, church, and state - it attracted a wider mass attention. The social and legal relations and aspects of Lithuanian rural family setting and its existence of different periods were really original and interesting. Researching the conception and development of the legal and social family relations and comparing them to the modern law, essential differences can be observed, but at the same similarities, which have not changed till our times, can be found. At all times the prevailing family model in Lithuania was the traditional family model and the main differences in comparison to the modern family model are the forms of marriage registration and its stability. This family model was predominant in the rural areas of late XIX century Lithuania.

2006
Kruma, Z. | Kreicbergs, V. | Adams, A.
During processing of aromatized rapeseed oils, volatiles from the added spices migrate in oil and give specific taste and aroma to oils, but there are no investigations about volatile compound migration in oil. The aim of this research was to determine volatile compounds in oils aromatized with basil, oregano, and thyme. In basil 43 volatile compounds, in oregano - 39, and in thyme - 37 volatile compounds were identified. In oil aromatized with basil - 8, in oil aromatized with oregano - 20, and in oil aromatized with thyme 11 volatile compounds were identified. From the total amount of identified compounds in spices, 23-30% of volatiles found in thyme migrated in oil aromatized with thyme, from oregano in oil migrated 12-15% of volatiles, but from basil in oil aromatized with basil - only 5% of volatiles. More volatile compounds as camphene, alpha-pinene, and alpha-thujene migrate in oil better than less volatile compounds like methyl chavicol, and thymal. Migration of the same compound in oil from various spices differed. It could be explained by the location of the volatile compound in plant structure.

2006
Kivite, J. | Karklina, D.
Several farmers of Latvia have established ostrich substituting traditional animal growing farms. Ostrich meat is frequently described as a healthy alternative to other meat products. Ostrich, a red meat, is even lower in calories, cholesterol and fat than skinless chicken and turkey, while remaining high in the content of iron and protein. The aim of the investigation is to evaluate the chemical composition of frozen ostrich meat obtain in Latvia and compare it with other meats. The samples of meat for experiments were obtained from ostrich meat producers. Moisture content was determined by drying of the samples at 100 deg C to a constant weight (ISO 6406). Protein content was determined by Kjeldahl method (ISO 5983). Fat content was determined by Soxlet extraction method (ISO 6492). The calories in different meats were determined by an approved procedure which includes summing of the calories from fat and from protein. The investigations showed that there were no significant differences between the main components of ostrich meat produced in Latvia and those found in the data in literature. Chemical composition of ostrich meat does not significantly differ from that of other types of meat. The research suggests that ostrich meat can be substituted for beef or chicken in any recipe, including meat-processing products.

2006
Miezite, O. | Dreimanis, A.
In the time of the decrease of global fossil resources storage wood, pulp has an increasing importance as a heat energy source. In Latvia, grey alder stands occupy 189.9 thousand ha with a total growing stock of 31.1 mil. m**3. So far in most of cases grey alder is estimated as a low value tree species, because tree dimensions do not to allow obtain a significant proportion of timber quality wood. The increasing fuel shortage has caused the need for growing grey alder as a bio energy supply. Grey alder has not been analyzed intensive until now, therefore the aim of the investigation is to estimate the stand productivity and or above ground biomass; that could serve as a background for recommendations to establish grey alder stands for energy-wood production. The grey alder biomass is dependent on wood density, but density - on wood moisture. The average newly felled grey alder wood density in April is 0.76+-0.011 g cmE-3, but absolutely dry wood density for trees felled in October, the average value of absolutely dry wood is 0.46+-0.005 g cmE-3, which is 1% more than in the spring, but these relationships are not significant relative moisture demonstrates water content in newly felled wood. Its average value is 54.7+-0.5% in April and 53.5+-0.05% in October. Empirical formulae are worked out for absolutely dry stem and branch biomass

2006
Jansons, A. | Baumanis, I. | Dreimanis, A. | Gailis, A.
Survival, growth (height, diameter at breast height, stem volume, yield) and quality (thickest branch up to 2 meters of tree height, branchiness, and stem straightness in grades) of phenotypically selected Scots pine plus-tree progenies from different regions in Latvia at the age of 32 years have been analyzed. The material was planted in 4 tests in different forest types (Cladinoso-callunosa, Vacciniosa, Hylocomyosa, and Oxalidosa) in Kalsnava, Eastern part of Latvia. Average number of trees per family varied from 11 to 21 (survival 18-35%). Mean height for Scots pine at the age of 32 years was 14.2 -16.3 m, coefficient of variation -10-17%, diameter at breast height - 13.1-17.7 cm, 24-32%, stem volume 0.1-0.2 m**3, 49-64%, diameter of thickest branch at up to 2 meters of tree height - 1.3-1.7 cm, 23%. To secure ability for detection of significant (alpha=0.05) family differences, average number of trees number per family at evaluation age should be at least 24. Narrow sense individual tree heritability (h**2) was 0.11 for stem volume, 0.09 for diameter at breast height, and 0.07-0.11 for diameter of thickest branch up to two meters of tree height.

2006
Dunska, I.
After Latvia has joined the EU, all the positive social and economic changes make us to believe that students' personalities will be developed in the same positive way. Of course it should be admitted that any changes in young personalities can be strongly affected by the university study course, its aims and content. Joining the EU allowed many Latvian students to use the possibility of studying and working abroad, and many of them are already using this chance not even thinking about the future of their native region. The majority of LUA students come from province as do many more from other higher schools but they differ from other higher schools but they differ from the previous generations with their more dynamical and free vision and more constructive actions. At the same time the idea of students' responsibility and upbringing their sense of affiliation to their native regions becomes more relevant. We investigated students' awareness of responsibility and civil maturity. The attention was paid to the development of students' patriotic attitudes during the acquisition of the course of studies at the institution of higher education. It is very important how a student's matured personality was developed. Love to the motherland was emphasized in Latvian pedagogy in pre-war years, but in our higher schools the idea of patriotic upbringing still remains at the very low level or sometimes does not even exist. The main objective for the higher schools management is initiating this process overwhelming student's drift away from their native district. The innovating rural tourism course for higher schools can be regarded as one of the possible instruments of patriotic upbringing.

Penke, D. | Katane, I.
The school's education surrounding is the places where social experience and children's learning opinion are gathered develop the system of attitudes. It values actualizes education's needs and develop the motivation of self-realization and develop motivates to continue the education. It is important to develop the skills to make a prognosis, to plan and to project the future. The aim motivation must be the real key in this process. The education of career is the school especially the main thing for rural schools that provide the long-term development during the crisis of demography and competition. The authors offer: 1) the typical needs of pupils for education in the surrounding of education, which is based on ecological approach in education and stresses the link between the surrounding and man in the holistic way, 2) the analysis of done investigations and evaluation in the part of discussions analysing the approach of career's education problems in the rural school, giving the references to other authors' views and investigations.

2006
La Rovere, Roberto | Aw-Hassan, Aden A. | Turkelboom, Francis | Thomas, Richard
Agricultural research in marginal dry areas can contribute to reducing poverty through the development of technological, institutional and policy options for poor farmers. Such research should address diversified opportunities and development pathways. This article analyses the diversity of livelihood strategies of rural people living in the Khanasser Valley in northwestern Syria, an area that is typical of marginal drylands. It proposes an operational classification of households based on their different livelihood strategies, applying an integrated methodology within a Sustainable Livelihoods framework. Households are classified into three clusters: agriculturists, labourers and pastoralists. The article examines the diversity of livelihoods involved, and considers where and how research should be directed to have greatest impact on poverty. Given that rural households are not homogeneous but dynamic entities, with diverse assets, capabilities and opportunities, the definition of household typologies can help to target development research. The article concludes that while agriculturists benefit most, poor labourers with enough land can also gain from pro-poor agricultural research. The poorest households with little land, and pastoralists, benefit little or only indirectly.
