The objective of this research was to design an economically efficient logistics management model for fuel retail enterprises to improve their competitiveness. In the current global market situation, fuel retail enterprises face various challenges, such as sharp increase in raw material price, intense market competition, high price sensitivity, low profitability, and significant logistics costs. By combining theoretical and practical insights, an improved logistics management model was designed, which provides significant competitive advantage for fuel retail enterprises. The designed model incorporates and integrates three distinct logistics arrangements, resulting in considerable advantages for fuel retail enterprises. These advantages include a reduction in logistics costs and increased independency from the fluctuating logistics service expenses. To determine the economic efficiency of the designed logistics management model, it was validated by using data obtained from a fuel retail enterprise based in Sweden. Results of the research indicated that the fuel retail enterprise can anticipate an annual reduction in logistics costs ranging from 2.91% to 3.32% from the implementation of the improved logistics management model. On top of that, the developed logistics management model is projected to be economically viable until 2027, assuming the continuation of the current market trends and conditions. The findings of the research suggest that other fuel retail enterprises may also benefit from implementation of the designed model in the current market conditions.

Developed transport and storage sector has up-most importance for production capacities in regions, especially in rural areas, ensuring supplies and deliveries, including well-developed and maintained infrastructure, transport vehicles, IT systems and human capital. Till 2040 demand for highly-educated and qualified logistics specialists will increase in Latvia due to growing labour costs, introduction of new technologies and digital solutions. The aim of the study is to identify the recent trends that give valuable findings for education and regional development policy elaboration and implementation in order to achieve balanced regional development promoting also rural development. The findings reveal that the higher the share of population with higher education the higher the wages. The regions with the larger share of population with higher education are mainly urban and pre-dominantly urban regions. However, transport and logistics sector is in all regions as well as demand for logistics specialists. Balanced regional development is crucial for sustainable development in national and the European Union level.

Innovations are very important condition and tool for competitive entrepreneurship. To obtain more effective approaches, researchers are devoting deepened analysis for many factors influencing innovations and innovative activities indicating that there is an important influence on different sources of information on innovations — own company, co-operation with universities and business incubators, with research organisations. Empirical research results were based on survey results of entrepreneurs and on analysis of obtained survey results by use of descriptive statistics indicators confirmed that entrepreneurs in Kurzeme region biggest inspiration get in their own company as well as from suppliers of equipment, programs and materials but they have less influence on information about innovations from universities and other higher education institutions as well as private organisations, also research organisations.

The strengths and weaknesses of Latvian business incubators across various regions of Latvia could be identified based on the analysis. This can help to make policy decisions and guide resource allocation to contribute to the development of the business incubator ecosystem in the future.

The topic of this article is relevant because in Lithuania the assessment of the area occupied by plantations and green spaces has shown that the area standards do not meet the requirements and recommendations of the World Health Organization. Green spaces are regulated differently in different countries of the European Union. Lithuania has also developed a legal framework for the protection, management and establishment of new plantations and green spaces. However, this legal framework is improving and new laws are being added to it. Comparative, analytical, as well as statistical, and logical analysis methods were used for the investigation. The data of the Land Fund of the Republic of Lithuania for 2002–2022 were used for comparative investigation. The aim of this article is to perform an analysis of the change in the trees and shrubs greenery area of Lithuania in 2002–2022. In Lithuania, for example, trees and shrubs occupied 84,687.48 ha in 2002. In 2022, the plantation area amounted to 208,609.48 ha. From 2002 to 2022 the area of tree and shrub plantations in Lithuania increased by 123,922.00 ha or 146.33%. The analysis shows that in the period between the years 2002 and 2022 the biggest increase in the area of shrubs and plantations took place in Utena County (32,715.83 ha or 395.27%), but the smallest increase in Tauragė County (2,642.93 ha or 37.69%) and Marijampolė County (4,581.39 ha or 72.25%). The development of plantation areas has been positively influenced by the creation of an appropriate legislative framework and the implementation of plantation programs in counties and municipalities.

Tourists’ environmentally responsible behaviour (ERB) in response to climate change is a topic that is becoming increasingly important during the Covid-19 pandemic as people’s values change. Tourism is facing an economic downturn and now is the time to prepare for a new upswing. Meanwhile, a new narrative is needed in response to climate change, as tourism is a net polluter of the environment. That is why tourist ERB studies are becoming more and more relevant in the world, including Latvia, too. The objective of this paper is to determine the ERB of tourists in response to climate change. The questionnaire included 30 research questions and generated 383 answers from respondents from the Vidzeme region of Latvia. Several research methods were used in the study: descriptive and correlation method, KMO and BARLETT’S, Cohen’s Kappa and Cronbach’s alpha tests, Exploratory factor analysis and Principal Components Analysis. The study found that the factors attitude, behaviour, awareness, control, environmental knowledge, experience and values influence tourists’ ERB; however, environmental knowledge and experience show a slight advantage. To direct the continuation of the research towards the creation of the tourism ERB model in Latvia.

Lowering emissions expelled from internal combustion engines has been the focus of researchers worldwide. Adding hydroxy gas to current internal combustion engines can be an effective way of lowering CO2, CO, HC and particle emissions, as well as improve combustion. Because of this, a review of previously conducted research on the addition of hydroxy gas to different internal combustion engines has been produced. During this review, it was concluded that addition of hydroxy gas can be an effective way of lowering fuel consumption and CO, CO2 and HC emissions in petrol engines, as well as fuel consumption and CO and HC emissions in diesel engines.

Universities play an important role in providing a wide range of services and connecting all stakeholders, such as employers, alumni, and other community members to prepare students for future employment, establish networking with labour market representatives, assist them in integrating into the labour market, and develop students’ as potential specialists’ employability skills, thereby fostering their career development in the university educational environment. The aim of this study is to analyse the career related theories and propose a career development model for economics and business-focused universities. The following research methods were used: desk study, analysis and evaluation of scientific literature (theoretical research method); reflection of personal experience (empirical research method). The theoretical research emphasised modern career-related theories and resulted in a proposal for a career development model for a university. A mandatory course that formally prepares students as prospective specialists for employment and internship, exposure to the labour market via internship, networking events, and mental support provided by qualified psychologists, university teachers as part of an academic advising programme and alumni organized in the form of an alumni mentorship programme, are the main pillars of the proposed career development model.

The phenomenon of global climate change holds utmost importance in its impact on forest ecosystems. To mitigate the effects of this phenomenon, several European countries have introduced non-native tree species into their forests. However, comprehensive ecological analysis is needed to assess the suitability of these non-native species. Pinus strobus is often considered a potential substitute for native species. Tree-ring analysis is a useful methodology for evaluating the relationship between tree growth and meteorological conditions, given the significant impact of these conditions on tree development. In this study, 25 core samples were collected from an experimental plantation of Pinus strobus located in the western part of Latvia for analysis. The plasticity of the tree-ring width of Pinus strobus was evaluated using a multiple additive regression model. The analysis revealed that the previous summer precipitation was a significant factor, indicating the drought sensitivity of the increment. Additionally, the temperature in the previous July and August was also found to be a significant meteorological parameter, suggesting some tradeoffs between growth and the formation of nutrient reserves. The estimated growth responses suggest that the radial increment of Pinus strobus growing outside its native range is highly weather-sensitive, implying uncertainty in its growth with anticipated climatic changes. These findings emphasize the need for further ecological analysis to determine the suitability of non-native tree species and their ability to withstand the climatic changes.

Mortality rates and co-morbidities are high in people with psychiatric disorders. These patients have unhealthy dietary habits, which include increased consumption of fast food, snacks, sweets, saturated fats, and reduced consumption of protein, fruits, vegetables, and legumes, which contributes to the risk of developing chronic diseases such as obesity, type 2 diabetes, and cardiovascular disease. Unhealthy and monotonous eating habits lead to a significant lack of nutrients such as protein, omega-3 fatty acids, B-group vitamins, and fibre. The aim of the literature review is to investigate the main diet problems of patients with psychiatric disorders and, based on the studies on the nutritional value of legumes, to evaluate their suitability for the development of new products for patients with psychiatric disorders. Studies show the beneficial effects of legumes on the regulation of rapid fluctuations in cholesterol, blood pressure, excess body weight, and glucose levels, which in general delay the formation of inflammation and reduce the risk of psychiatric disorders. The benefits of legumes are due to their high protein and fibre content, low fat content, and content of iron, copper, magnesium, zinc, and B-group vitamins. In addition, legumes contain bioactive compounds that contribute to the prevention of chronic diseases.
