At the onset of the emergency, Latvia, like many parts of the world, experienced uncoordinated collective behavior that could potentially lead to significant changes in food supply chains. Therefore, one of the research directions of The National Research Program project “Towards the Post-pandemic Recovery: Economic, Political and Legal Framework for the Preservation of Latvia's Growth Potential and Increasing Competitiveness” (recovery-LV) (2020) was to find out how the Covid-19 crisis Restrictions have changed buyers' habits towards buying and consuming food. The article summarizes and analyses the research results of the content analysis, semi-structured interviews and survey conducted within the project. An analysis of the results shows that, as a result of the crisis, consumers are less likely to visit outlets, cook more often at home and choose more locally sourced food. It was concluded that the consumer agitation regarding the purchase of food products in 2020 was short-lived, which later returned to the usual limits of the habits of various socio-demographic groups of the population.","PeriodicalId":63151,"journal":{"name":"黄河文明与可持续发展","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84558225","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}

Although it is very easy nowadays to do many kinds of work remotely, many companies still do not want to introduce such practices on a permanent basis. Therefore, the research aims to examine the experience of companies in remote work to identify the economic benefits of remote work as well as develop scenarios for remote work. The research methodology is based on case study analysis, comparative analysis, economic analysis and the scenario method. The results of the research revealed that potential financial savings from applying remote work practices in companies varied, depending on the specifics of the industry and jobs, as well as the funds that the company was initially willing to invest in its employees. For companies, the largest economic savings from applying remote work practices came from maintenance of premises, as well as electricity and Internet bills, while the provision of equipment to their employees accounted for the smallest proportion of preliminary cost savings. However, the main disadvantages of remote work were the difficulty of controlling employees, communicating effectively with each other and ensuring successful teamwork. Companies could introduce part-time work practices if a large proportion of the tasks could be performed remotely, yet only the companies with a high level of automation of tasks might fully switch to remote work.","PeriodicalId":63151,"journal":{"name":"黄河文明与可持续发展","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72858056","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}

One of the most important tasks for investors in the context of the coronavirus crisis is the analysis, assessment and effective management of risks that can affect investment projects before investing. And also, the investor must identify the factors that negatively affect the project and develop measures to reduce their negative impact. Based on the above, it can be said that improving the risk management methodology and evaluating investment projects based on modern and best practices has become one of the urgent tasks. In this article, the author explains the essence of risk management and presents the main stages of risk management developed by foreign and domestic economists, and also expresses her own opinion about the stages of risk management of investment projects in the form of a scheme. The article also presents the content of the methods of risk analysis that are frequently used in practice. In particular, the author shows the essence of methods for assessing investment risks, such as Break-even point, the sensitivity analysis of the project, the method of Scenarios, the method for assessing the sustainability of the project, Expert evaluation method, Analogy method, and others. We can identify two aims of research: 1) to study the stages of investment risk management, developed by foreign and domestic scientists, and, on their basis, to propose the stages of risk management, developed by the author; 2) to study various methods of risk assessment, which are a key part of investment risk management, and develop proposals for their application in Uzbekistan. To achieve the objectives of the study, the following tasks were identified:  explain the content of the economic categories “risk” and “investment risk”;  explain the content of investment risk management;  study of the process (stages) of investment risk management, developed by foreign and domestic economists;  development by the author of the stages of the investment risk management process;  study and outline methods for assessing the risks of investment projects;  development of recommendations on the application of risk assessment methods in Uzbekistan.

Innovating or anticipating disability-related social innovations can contribute to product and services for disabled people, but also to eliminate social barrier and to integrate them into society. The aim is to analyse the ways for implementation of social innovation which is bringing maximum value of life for people with disabilities. We expect that factor values affecting people with disabilities may vary since we have different regional infrastructure, social support and services. This literature review study sheds researches social inclusion among people with disabilities. Results: We investigated main domains and factors representing main values for people with disabilities. Findings from this study indicate that people with disabilities may feel deep depression and anxiety in response to social isolation. This study may contribute to values of perceived isolation and promote social barrier elimination. Conclusion: The social tasks associated with regional disability-oriented infrastructure as support require attention in literature. Offering social innovation and assessing current level of needs in regions to people with disabilities will significantly increase social value.","PeriodicalId":63151,"journal":{"name":"黄河文明与可持续发展","volume":"61 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82654504","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}

Since 2007, biogas production in Latvia has increased significantly, as it was possible to receive co-funding from the EU Funds for the construction of biogas plants. In 2021, inputs of agricultural origin are used by 40 biogas plants with an average installed capacity of 1 MW. The emergence of biogas plants on livestock farms is facilitated by the development of a circular economy producing waste from the production process – manure and feed waste. Anaerobic fermentation results in digestate – a nutrient-rich plant fertilizer that reduces the application of chemical fertilizers. Rational use of biogas can reduce the need for fossil fuels. Energy production from biogas should be encouraged, as waste is used efficiently, thereby generating energy and reducing the release of greenhouse gases into the atmosphere. In Latvia, livestock production is one of the key industries of the national economy, which produces manure and feed waste. The present research calculated the amounts of cattle, pig and poultry manure and feed waste in Latvia. The research analysed livestock farms by number of cattle, pigs and poultry, the potential amounts of manure and waste produced and theoretical biogas output. Theoretically, 309 farms analysed can produce 93.5 mln. m3 of biogas from agricultural waste and construct 269 new biogas plants. A policy for supporting the construction of new biogas plants would contribute to the country’s independence from fossil energy sources, as well as increase the proportion of renewable energy sources to 50-70 % in final energy consumption by 2030. Farmers on whose farms a biogas plant could be built need to carefully consider the uses of the biogas produced. The uses could be thermal energy generation for heat supply, cogeneration (thermal and electrical energy) or biomethane production.","PeriodicalId":63151,"journal":{"name":"黄河文明与可持续发展","volume":"88 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81396594","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}

Authors looked for information related to the following questions: what are the criteria for evaluating logistics service providers; what are the requirements that logistics providers need to ensure to become a partner; what are the objectives of the selection contests (procurement tenders) defined by the companies; what are the main service quality indicators that are used to measure the performance of logistics service providers. Companies originated in the European Union from various countries have been examined. A literature review was conducted that helped to collect information regarding application of multiple-criteria decision-making for selection of logistics service providers and extract proposed selection criteria. Analysis of procurement documentation by logistics service providers was done to extract and group data that will be used to develop decision-making framework in further research. Authors created unique groups of logistics service providers selection criteria, requirements towards logistics service providers, selection goals and key performance indicators. Finally, general market research of pre-defined industries was made. There are very few studies dedicated to selection of criteria and requirements towards logistics service providers.

The development of information and communication technologies in the 21st century has transformed everyday work and life, and it was expected that, over time, teleworking would become a common practice in most companies. However, it was slower than initially expected due to various social and organizational factors. The COVID-19 pandemic accelerated the shift to forced remote work, creating problems and challenges for both employers and employees. This proves that new approaches and solutions are not only possible, but also useful and necessary. In order to find out what challenges employers have faced in the transition to remote work and what experience they have gained in order to solve them, two focus group discussions were organized with employers of Vidzeme region from different sectors. In order to compare the experience of employers and employees, a survey of 495 remote-working respondents was conducted between September and October 2020. The research data were collected in the framework of the National Research Programme project “Life with COVID-19\", during the first wave of the pandemic. The study reveals that the main challenges were to adapt business processes to the constraints of the emergency and the work organization of remote work, which requires new knowledge and skills such as how to sell, communicate, motivate, teach remotely and ICT skills. Teleworking during the COVID-19 pandemic posed challenges such as occupational safety risks, health risks, separating work from leisure time and acquiring new knowledge and skills in a short time.","PeriodicalId":63151,"journal":{"name":"黄河文明与可持续发展","volume":"112 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77847271","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}
