Environmental sustainability aspects in short food supply chains: The views of organic farmers and consumers
2023
Ušča, Maija | Aļeksējeva, Lāsma
Globally, food systems are the most significant cause of environmental change; therefore, efforts to create more environmentally sustainable food systems are presented. One of the directions is strengthening the local actors and short food supply chains. Simultaneously, changes in farming systems are needed, and organic agriculture is one of the ways to make food systems more environmentally sustainable. Despite the abundance of research on the environmental consciousness of consumers in short food supply chains, the question is raised whether local food chain farmers are also committed to environmental sustainability. Therefore, this paper aims to explore the importance of environmental sustainability to organic short food supply chain actors. More specifically, the research depicts the views of organic farmers and consumers and their relation to the actual environmental sustainability of short food supply chains. During the research, a specific short food supply chain – a direct purchasing network – was explored. A qualitative approach was applied to reach the aim. Thus, in-depth interviews and observations were used as a research method. The research results demonstrated the views of farmers and consumers of the specific network regarding environmental sustainability aspects in the network. In the research, such environmental aspects as the circularity of resources, biodiversity, chemicals in the environment, seasonality and locality of diets, and the distance (food miles) were admitted as crucial ones by the specific short food supply chain actors. The differences in opinions of consumers and farmers emerged when thinking about the scale of their views.

2023
Sabunevica, Stefanija | Zagorska, Jelena
In recent years, the demand for organic fermented dairy products has been growing. Lactic acid bacteria (LAB) are of major interest in the food industry due to their ability to form the quality and functionality of fermented products. A significantly higher LAB cell count is presented in organic (ORG) fermented products such as yoghurt and kefir, than their conventional (CONV) counterparts. There is still a lack of information on the possible explanation and evidence of ORG milk as a better medium for LAB growth. The aim of the present review is to summarise the results of research articles on the milk compounds and their effect on LAB growth, and to identify differences between ORG and CONV milk that may provide a plausible explanation for their influence on LAB growth in ORG milk. The monographic method was used in this study. According to the previous research, significant differences were established in a content and range of carbohydrates, nitrogen sources, fats, macro elements and microelements, as well bioactive compounds in ORG and CONV milk. The composition of ORG milk may have potential benefits for the development of LAB due to the higher concentration of peptides and long-chain polyunsaturated fatty acids in it.

2023
Roscher, Bjarne Erik | Balina, Signe
This research in progress paper investigates the multifaceted factors shaping the work-related attitudes of top managers in organizations with a focus on Germany. Through in-depth interviews with seasoned experts, it reveals crucial work attitudes, examines the impact of interpersonal and procedural factors, and evaluates information’s role in the principal-agent relationship at top management levels. The findings challenge conventional assumptions, providing different perspectives on leadership and highlighting the evolving nature of management practices in the digital age. The study also explores potential differences between top IT managers and other C-level roles, investigating their implications. The results of this research based on expert interviews are used in a broader context of research to triangulate literature analysis findings and quantitative surveys in order to develop a comprehensive understanding of factors influencing top managers’ work attitudes. Semi-structured expert interviews were conducted to gain a comprehensive perspective on the influencing factors of work attitudes in top management functions. Six German experts participated, bringing diverse backgrounds and affiliations with professional associations. Despite varied perspectives, universal importance was identified in key work attitudes, challenging assumptions of significant differences between employer and employee representatives. A novel contrast between hierarchical and broader perspectives within owner and worker associations emerged, suggesting a need for a more comprehensive understanding of management approaches. Additionally, interpersonal factors in leadership, information flow, trust-building, were highlighted as contributions. Furthermore, distinctions and commonalities between IT management and other top managerial roles were identified. This study both confirms existing knowledge and introduces valuable insights to management science, potentially shaping future research and practices.

2023
Roziņš, Rihards | Brencis, Raitis | Spulle, Uldis | Spulle-Meiere, Ivanda
It is well known that wood tends to shrink and swell as the relative humidity of the air changes. There have been, and still are, attempts to make dimensionally stable wood panels such as Dendrolight®. The physical-mechanical, operational, including acoustic, properties of this material have been significantly improved compared to traditional wood-based panels. However, the production of this material requires very specific processing equipment and a large energy investment. The developers of this material in Latvia invented and patented wood, Lightweight Stabilised Blockboard (LSB). In order for this material to be used in the production of various products, it is necessary to clarify its characteristic, technological, as well as operational properties. The study gathers information about the sound absorption properties of various natural and wood materials, characteristics, and the sound absorption of the studied material at different sound frequencies. The reviewed sources of information indicate that nowadays there are still problems in sound conduction and absorption and isolation issues are being addressed in building acoustics. The production of samples and the determination of sound absorption were carried out using a developed methodology developed in accordance with regulatory requirements. The data obtained in the practical study were compared with the relevant indicators of the Dendrolight® and wood-based panels used for building structures and to determine their compliance with the requirements set forth in the standards ISO 10534-2 and ISO 11654. Research data show that LSB corresponds to E sound absorption class in some of the investigated frequencies.
