Cross-lingual document retrieval categorisation and navigation based on distributed services

The widespread use of the Internet across countries has increased the need for access to document collections that are often written in languages different from a user’s native language. In this paper we describe Clarity, a Cross Language Information Retrieval (CLIR) system for English, Finnish, Swedish, Latvian and Lithuanian. Clarity is a fully-fledged retrieval system that supports the user during the whole process of query formulation, text retrieval and document browsing. We address four of the major aspects of Clarity: (i) the user-driven methodology that formed the basis for the iterative design cycle and framework in the project, (ii) the system architecture that was developed to support the interaction and coordination of Clarity’s distributed services, (iii) the data resources and methods for query translation, and (iv) the support for Baltic languages. Clarity is an example of a distributed CLIR system built with minimal translation resources and, to our knowledge, the only such system that currently supports Baltic languages

CIRCULAR ECONOMY AS A TOOL FOR SUSTAINABLE DEVELOPMENT: A THEORETICAL PERSPECTIVE

Climate change, depletion of natural resources, social inequality and poverty, a lack of food resources, etc. issues related to world sustainable development has become increasingly relevant in the last 50 years, negatively affecting people\u27s opportunities, and living standards in various countries. Despite these problems, the average level of wealth of the population in the world is gradually increasing over time. Considering forecasts on population growth by the end of the 21st century, it must be admitted that the current world-dominant linear economic model is fully unsustainable in resource consumption, as there is a natural barrier to economic growth. The aim of the present research study is to explore the potential of the circular economy as a tool for achieving sustainable development, based on a theoretical framework. This paper was built based on a broad literature review to examine the limitations and conceptual gaps of the circular economy concept as a tool for achieving sustainable development. It has been concluded that the circular economy concept undeniably has huge potential to promote sustainability within planetary boundaries as well as it can be implemented to decouple economic growth from the utilization of finite resources. However, a broader analysis of the circular economy concept allows us to assert that to date, a clear and effective approach for the transition to this economic model, affecting all areas of sustainable development (i.e. environmental, economic, social) has not been developed. In addition, the circular economy concept is still evolving, there is a tendency to view the circular economy concept holistically, covering various sub-concepts of the circular economy under the common Sustainable Circular Economy concept\u27s umbrella

INTEGRATION OF THE POPULATION AT RISK OF SOCIAL EXCLUSION INTO THE LABOR MARKET: ANALYSIS OF THE SITUATION AND SOLUTIONS

The topic of the scientific work is "Integration of the population at risk of social exclusion into the labor market." Analysis of the situation and solutions\u27\u27. Population at risk of social exclusion is a group of people who have an increased risk of ending up in situations of social exclusion or who are already in situations of social exclusion. State financial resources are insufficient to solve all socio-economic problems. In recent years, social entrepreneurship has been an active mechanism for solving socio-economic problems. Social entrepreneurship and a type of business whose priority is the creation of social assets, a company of financial self-sufficiency and sustainability. The author of the paper conducted an in-depth analysis of the situation regarding the integration of the population at risk of social exclusion into the labor market, and based on the knowledge gained, developed recommendations and proposals

Influence Of Wastewater On Zooplankton Community Of The Daugava River After Daugavpils Wastewater Treatment Plant Modernization

During seasonal studies 2010 (May-October, once/ thrice a month), samples of zooplankton were collected at the Daugava River section from 10 km upstream to 10 km downstream from the Daugavpils treatment plant wastewater discharge into the Daugava River. Changes in the quantitative and qualitative characteristics, saprobity index and species diversity (Shannon-Wiener index) were employed for the analysis of zooplankton community structure in the Daugava River. The Daugava River is polluted by Daugavpils wastewater, however the untoward influence of pollution on zooplankton is observed only in years and in seasons with low water level and discharge. The effect of Daugavpils wastewater pollution on changes in the zooplankton community is considered

PRINCIPLES OF A CIRCULAR ECONOMY IN THE FOOD SECTOR: A SYSTEMATIC LITERATURE REVIEW

Since the transition to a circular economy (CE) in various sectors is a priority strategic goal of policy planning in the European Union (EU), the goal of this article is to reveal the principles of the CE in the food sector. To achieve the goal, the study is based on a systematic literature review using the literature synthesis and analysis method and the PRISMA 2020 approach for the selection of appropriate literature. From 25 articles, which were selected from the SCOPUS database, 20 were left for final analysis. Based on the literature review, it was discovered that the main principles of the CE in the food sector are management of resources and waste, emission control, natural and production resource sustainability, increase in energy efficiency, reduction and prevention of food waste, recycling and reuse of food waste and public involvement in the transition to the CE. The determination of CE principles in the food sector is the basis for choosing goals and a right strategy for the implementation of CE principles in practice in this are

THE DAUGAVA (ZAPADNAJA DVINA) ZOOPLANKTON FROM SUROZHA (BELARUS) TO DUNAVA (LATVIA)

The research has been done on qualitative and quantitative composition of zooplankton in the Daugava between Suroza and Dunava. The investigation was carried out in July – August 2008. The collection of samples was done using the net with 65µ mesh. For analysing the abundance of zooplankton method APHA 10200 was applied. Samples from 21 places were analysed assembling from the right side, left side and midchannel of the river. Species Rotatoria, Cladocera and Copepoda were found and zooplankton communities and diversity of species in the Daugava left side, right side and midchannel were compared taking into account the factors affecting them

Review of Cryptosporidium and Giardia in the eastern part of Europe, 2016

Introduction: This paper reviews the current knowledge and understanding of Cryptosporidium spp. an d Giardia spp. in humans, animals and the environment in 10 countries in the eastern part of Europe: Bosnia and Herzegovina, Croatia, Czech Republic, Estonia, Hungary, Latvia, Poland, Romania, Serbia and Slovenia. Methods: Published scientific papers and conference proceedings from the international and local literature, official national health service reports, national databases and doctoral theses in local languages were reviewed to provide an extensive overview on the epidemiology, diagnostics and research on these pathogens, as well as analyse knowledge gaps and areas for further research. Results: Cryptosporidium spp. and Giardia spp. were found to be common in eastern Europe, but the results from different countries are difficult to compare because of variations in reporting practices and detection methodologies used. Conclusion: Upgrading and making the diagnosis/detection procedures more uniform is recommended throughout the region. Public health authorities should actively work towards increasing reporting and standardising reporting practices as these prerequisites for the reported data to be valid and therefore necessary for appropriate control plans.Peer reviewe
