Dyscalculia is a cognitive disorder, math anxiety – emotional. Dyscalculia is a mathematics learning difficulty which is a brain-based condition connected to information organization and proceeding. In turn, mathematical anxiety is one of the emotional factors that causes learning difficulties in mathematics. Therefore, to promote progress in mathematics, the aim of this study is to identify learning difficulties in mathematics from the perspective of teachers and parents, to identify existing experiences in overcoming these learning difficulties in mathematics, and to determine the support needed by teachers. To achieve this goal, both parents and teachers have been surveyed as part of this study. About one-fifth of students have signs of dyscalculia, but 25% – mathematical anxiety. In Latvia, the most problematic type of dyscalculia is the ability to perform mathematical activities and perform both operational and practical calculations, but mathematical anxiety is equally common at all stages of education. According to a survey of teachers, only 7% of students have no mathematics learning difficulties. Parents associate children’s learning difficulties with the organization of the learning process (intensive curricula, when the teacher does not have the opportunity to implement a differentiated / individual approach), as well as teachers’ attitudes. Research shows that teachers are unable or unaware of how to determine whether a student has dyscalculia or math anxiety and do not have appropriate skills, know-how or training to help a student who experiences learning disabilities and difficulties with mathematics.","PeriodicalId":34950,"journal":{"name":"Livestock Research for Rural Development","volume":"64 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80188013","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}

Up to date, eight P. tritici-repentis races have been described based on chlorosis, necrosis, or both symptoms caused on race differential wheat genotypes: ‘Glenlea’, 6B662, 6B365, and ‘Salamouni’. Symptom development on differential genotypes depends on the interaction of the pathogen’s necrotrophic effectors named Ptr ToxA, Ptr ToxB, and Ptr ToxC with host susceptibility genes. Ptr ToxA is encoded by the single copy gene ToxA and induces necrosis on sensitive wheat cultivars. Ptr ToxB causes chlorosis and is encoded by the multicopy gene ToxB. The Ptr ToxC is the non-proteinaceous, polar, low molecular mass molecule that also induces chlorosis, but up to date, the gene encoding this toxin is unknown. Races producing Ptr ToxA are predominant in the global Ptr population. There are several reports about new putative races of P. tritici-repentis that do not conform with the current race system, so further research is required. This study aims to collect and systematise available information about the virulence and races of P. tritici-repentis.","PeriodicalId":34950,"journal":{"name":"Livestock Research for Rural Development","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72676331","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}

The purpose of the research is to use construction inspection strategies associated with artificial intelligence to predict the market value of a residential apartment. In this academic experiment, only 6 samples of residential apartments are used. Those samples are located in the Lithuania Republic square at Vila Zelina neighborhood, in São Paulo, Brazil, a source in February 2021. The method uses the results of the inspection of civil engineering and converts them into linguistic terms. The result considers the imprecision, uncertainty, and subjectivity of human expression combined with artificial intelligence and civil engineering. To test the feasibility of the process, a comparison is made between the market values of the samples and the values predicted by the Fuzzy logic.

The willingness to do remote jobs was also examined, and the picture of prone to remote job employee by demographic characteristics of the respondents was drawn. The most convenient distant locations, informational and communication technologies (ICT) and addresses of indirect communication were identified. It was found that survey participants are not resistant to work remotely, and it also showed that at least partially remote job could be designed in majority of Lithuanian companies. Most of them prefer flexible mixed variation of remote and traditional work.

In order to reduce agricultural GHG emissions, agricultural practices have to promote sustainable land management by helping to prevent soil erosion and creating the potential to increase soil carbon stock. Sustainable soil management includes reducing tillage and introducing legumes in crop rotation. The aim of the study is to identify the impacts of the soil tillage and the cultivated crops on formation of GHG emissions. The study site has 24 experimental fields where two types of soil tillage have been used and four crops where grown (wheat Triticum aestivum, rape Brassica napus, beans Vicia faba and barley Hordeum vulgare). Soil humidity, soil temperature and measurements of GHG emissions have been carried out during the plant vegetation period from 2018 to 2020. GHG emissions where measured using Picarro G2508. A total of 460 measurements of GHG emissions were made in 2018, 2019 and 2020. The minimum value of N2O emission is -19.5 g ha-1 day-1, but the maximum is 273.4 g ha-1 day-1. CH4 emission has a minimum value of -84.8 g ha-1 day-1, and a maximum of 514.1 g ha-1 day-1. The minimum value of CO2 emission is -13.0 kg ha-1 day-1, but maximum of 1026.7 kg ha-1 day-1. The results of CO2, CH4 and N2O emissions show a significant discrepancies between the arithmetic mean and the median values which indicates the observed extreme values.

Social farming is both a new and a traditional concept. It originates from the traditional rural self-help networks that were well established in rural areas before the modernisation of agriculture and the rise of the public welfare system. Social agriculture covers at least three dynamic areas of society – rural development, social entrepreneurship and the growing demand for social care services, and it is closely linked to the concept of multifunctional agriculture. As a form of social entrepreneurship, social farming could create the opportunity to reconnect farmers with their local communities through the opening of their farms as part of the social support system of the community. Caring for people with dementia is a particular challenge. Currently in Latvia, families where one of the family members has dementia have only two options - to place their relatives in a care institution or to take care of them in the family. Foreign experience shows that social care farms can provide care services to people with early dementia. This paper, exploring demand for these services in Latvia, is based on the case study of families caring for persons with dementia in Rūjiena municipality in April 2020.","PeriodicalId":34950,"journal":{"name":"Livestock Research for Rural Development","volume":"47 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90853508","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}

However, there have been many foodborne outbreaks in Europe, the United States, and other parts of the world associated with pathogens contamination of sprouts. These outbreaks pose a constant challenge to the entire sprouts industry. The aim of this study was to determine the presence of Shiga toxin-producing Escherichia coli (STEC), Salmonella spp., and potentially pathogenic bacteria in germinated grains and seeds intended for industrial food production and ready for use without further processing. In this study, grains of wheat (Triticum aestivum), seeds of broccoli (Brassica oleracea), alfalfa (Medicago sativa), radish (Raphanus sativus) and hemp (Cannabis sativa) were germinated for 72 hours and were evaluated compared with ungerminated grains and seeds. The presence of E.coli was assessed by the inoculation of enrichment broth to Tryptone Bile X-glucuronide (TBX) and Eosin methylene blue (EMB) agars, and colony characterization with MALDI-TOF. E.coli was carried out in accordance with LVS ISO 16649-2:2007. The presence of STEC was determined in accordance with ISO/TS 13136:2012. Salmonella spp. detection was in accordance with ISO 6579-1:2017. As a result, E.coli, Salmonella spp., and STEC were not found in any sample. However, environmental bacteria were detected in TBX dry seeds and 12 h – soaked seeds. The presence of Enterobacteriaceae was found in all samples by colony characterization on EMB by MALDI-TOF.

Using SWOT analysis matrix, strengths and weaknesses, opportunities and threats of the compliance system for Ukrainian agricultural enterprises have been identified. It has been established that the agricultural business is able to ensure the implementation and operation of the compliance system, which is focused on international compliance values. An algorithm for introducing a compliance system into the activities of agricultural enterprises has been proposed. Its implementation and observance will allow agricultural enterprises to minimize compliance risks, ensure their financial stability and innovative development, increase trust of customers, partners and investors to be competitive both in the domestic market and external one. It has been determined that compliance risk management is a cyclical process, whose main goal should be to minimize the identified risks using the development and implementation of appropriate control procedures and measures. In order to minimize compliance risks arising in the process of relations between agricultural enterprises and counterparties, an organizational model of their management has been proposed. The application of the methodological approaches presented in the model will allow agricultural enterprises to establish working relationships with counterparties, including foreign ones, and in the future to attract foreign capital and investment in their activities.","PeriodicalId":34950,"journal":{"name":"Livestock Research for Rural Development","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81514830","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}
