Former peat extraction fields are a type of flooded lands which are often mentioned as significant source of greenhouse gas (GHG) emissions. In Latvia, the area of flooded lands in former peat extraction fields is 5.3 kha. The aim of the study is to evaluate GHG emissions from flooded former peat extraction fields to define that the flooded lands are the key source of GHG emissions and approve that further studies are necessary to elaborate country specific emission factors. The study is implemented in three areas in central part of the country, where peat extraction was stopped 25-35 years ago. Measures continued for 12 months, in 9 subplots, each was represented by 3 measurement points. Water and air temperature, as well as water level was measured during the study. According to the study results, flooded areas are a significant source of CO2 emissions (967±107 kg CO2-C ha‑1 yr-1); however, the most significant agent of GHG emissions in flooded areas is methane (CH4) – 435±98 kg CH4-C kg ha-1 yr-1. Flooded areas are not significant source of nitrous oxide (N2O) emissions. The net emissions from flooded areas are 18.1±3.7 tons CO2 eq ha-1 yr-1. According to the study results, flooded lands are a significant (one of the largest) source of emissions, and further studies are necessary to improve GHG modelling solutions and activity data.","PeriodicalId":226281,"journal":{"name":"Research for Rural Development 2022 : annual 28th International scientific conference proceedings","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128667081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Monographic method was used to analyse pulse seeds chemical content, possible pre-treatment methods, functional properties, covering the latest information about high-moisture extrusion, raw materials and technical parameters used. Pulses are a good source of protein, carbohydrates, minerals and vitamins. Chemical content, functional properties of yellow peas and different varieties of beans, except grey peas are well described in scientific literature. Germination can be promising pre-treatment for pulse seeds, it increases folic acid content, water absorption capacity and reduces the amount of antinutrients. Extrusion technology increases ready product protein digestibility and induces changes in antinutrient activity. High-moisture food extrusion characterises with moisture of raw materials above 40.00% where mostly protein concentrate and isolates from pulses are used.","PeriodicalId":226281,"journal":{"name":"Research for Rural Development 2022 : annual 28th International scientific conference proceedings","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122222356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to reduce the unemployment rate, it is necessary to increase motivation and incentives to look for a job, to improve readiness for work and help to find a suitable job, as well as to expand employment opportunities. Public employment services have become an important point for jobseekers, giving workers and employers access to a number of passive and active labour market support mechanisms. Active labour market policies are a key tool through which welfare states seek to improve the employment prospects of the unemployed. Ongoing monitoring and evaluation of the impact of active labour market policies and programs are needed to strengthen the effectiveness and efficiency of policies in responding to the needs of different groups. This study analyzes the data obtained from the survey of the unemployed with the aim of finding out how actively the unemployed cooperate with the state employment service and use services offered by it, as well as to reveal the possible shortcomings and shortcomings of this society, so that it is possible to eliminate them and increase the efficiency of this cooperation.","PeriodicalId":226281,"journal":{"name":"Research for Rural Development 2022 : annual 28th International scientific conference proceedings","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129262406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three different spectral compositions – red & blue (RB), red, green & blue (RGB) and red, green, blue, yellow & orange (RGBYO) LED luminaires and fluorescent light (FL) as control were used. Photon flux density of 110 μmol m-2 s-1 and 16/8h light/dark photoperiod was maintained for all luminaires. Stem and leaf morphological characteristics were affected by clone specific reaction to light treatment, while fresh and dry weight were affected only by clone. Partially opposite effect of red light amount in combination with yellow and orange light (RGBYO and FL luminaires) was observed on total plant length and main shoot elongation for two of ten birch clones. Length of third internode (four of ten clones) and leaf total and average area (three of ten clones) were stimulated by red light in combination with yellow and orange light. In general, our study shows that silver birch in vitro cultures exhibit clone specific, light-dependent morphological plasticity. We conclude that fluorescent lamps can be replaced with RGBYO, due to optimal spectral composition emitted by this luminaire and potential to adjust proportion of red light, thus providing individual approach for propagation of high-quality genotypes.","PeriodicalId":226281,"journal":{"name":"Research for Rural Development 2022 : annual 28th International scientific conference proceedings","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121110506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, health literacy (HL) skills development in Latvia, also in other OECD countries, is a priority area. Insufficient HL information base in Latvia is a fundamental basis for the research goal: to determine factors influencing HL and their changes among the population of Vidzeme statistical region (LV008) in Latvia. The study compares the authors’ 2020 study based on the European Health Literacy Questionnaire (HLS-EU-Q47). The study includes survey of respondents (n = 383) using pen-and-paper interviewing (PAPI) and telephone interview approach. Various methods and tests were used: Principal axis factor analysis (PFA) with varimax rotation, Confirmatory factor analysis (CFA), Compare means Independent-sample T-test, Anova, Kaiser-Mayer-Olkin (KMO), Bartlett’s test and Chi-squared test, Cronbach’s and Spearman-Brown methods, correlations (Pearson and Spearman’s) and Multiple linear regression (MLR) with Assumption Testing analysis, and Cronbach’s test. The study identified four factors influencing health literacy: access, understanding, evaluation, and use. Compared to the study conducted by the authors in 2020, which determined that education has a positive impact on factor – access, the HL has increased more strongly in the age groups 18-19, 20-29 and 30-39. However, among women the HL level has decreased compared to the previous study by authors and HLS-EU, the proportion of people with sufficient and excellent HL in the European Union has increased overall by 13.5%, while the proportion of people with limited HL decreased by 24.4%.","PeriodicalId":226281,"journal":{"name":"Research for Rural Development 2022 : annual 28th International scientific conference proceedings","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116786577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the determinants of inflows of FDI are often analysed at the regional and national level, the impact of the EU funding on the spatial distribution of FDI between the administrative entities within a single country is not extensively studied. The research objective is to assess the possible net impact of the EU funding on FDI inflows in Latvian rural districts, thus enabling the more targeted policy decisions with respect to the structure in future EU funding. To evaluate this impact, Instrumental Variables method is applied using the panel data on Latvian rural districts. The research results confirm that positive direct impact of the EU funding on the FDI inflows in Latvian rural districts exists, and it is substantial and statistically significant. At the same time, confounded ‘third factors’ might exist with negative impact on FDI inflows. While the spatial distribution of the FDI inflows in several regional aspects is rather uneven, the respective differences in the EU funding are less pronounced confirming the existence of negative ‘third factors’. Hence, the structure of the support by EU funds has to be revised to improve the local potential determinants of the FDI inflows with emphasis on infrastructure and human capital.","PeriodicalId":226281,"journal":{"name":"Research for Rural Development 2022 : annual 28th International scientific conference proceedings","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132886310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thirty-four cows of the local black-and-white breed of the second lactation (24–47 days after calving) were transferred from a brick barn for 100 heads with tie-stall keeping in a newly low cost housing facility for 400 heads with free-stall keeping. Milking equipment also changed: before the changing conditions of keeping, cows were milked in the milk duct at UDM-100, and after changing the conditions in the milking parlor at Carousel, 32 cows were milked at the same time. We divided the first 30 days in the new conditions of keeping and milking into VI periods. The duration of the main behavioral reactions: lying down, drinking, and eating food in the first days after changing the conditions of keeping and milking decreased significantly – by 181; 13 and 89 min, respectively. Behavioral responses at the end of the adaptation period (30 days) was lower than on the last day before changing housing and milking conditions. During the first 5 days after the change of housing and milking conditions, the average productivity of cows decreased by 1.39 kg (or 6.01%), content of milk fat, protein and lactose by 0.03; 0.02 and 0.04%, respectively compared to the last day before the transfer of animals.
