Social media networks are increasing in popularity and have been integrated into many aspects of daily life. Analysis of the ways in which individuals use social media is important for understanding social, cultural, and environmental issues. This study examines experiences of farmers’ market customers through their self-expression on social networks. Contributions to the Instagram social network based on the #farmersmarket hashtag were gathered on a single day, yielding 19,398 contributions created by 13,862 users. Six major linked hashtags were identified (#Organic, #Fresh, #Food, #Local, #Vegan, and #Healthy), providing key indicators of the characteristics of farmers’ markets that are valued by customers. Four customer segments were identified: Product Oriented, Emotional Oriented, Social Oriented, and Product-Social Oriented, with strong interconnections identified between these communities. The results of this study provide insights into consumer values and behaviors in the farmers’ market context and will be of practical use for future marketing and management.
Business modelling facilitates the understanding of value creation logic in organizations in general. Identifying the components of business models based on different criteria helps understanding the fundamentals of business and the position of entrepreneurs and managers in companies. The present research is focused on the definition of a specific business model for the Czech agribusiness sector. Based on the theoretical background and evaluation of selected business models, the aim is to create a new business model, using components which take into account the specifics of this particular industry.
Comblike glycodendrimers were prepared by the chemoselective ligation of cysteine-modified glycopeptides (1-7) with a 3-maleimidopropionate-modified linear synthetic carrier (8). Glycodendrimers bearing mono-, di-, or tri-Tn clusters (9-11) were tested as inhibitors using plant and mammalian lectins. In the former group, the Codium fragile lectin showed moderate discrimination among 9, 10, and 11. In the latter group, A and B isoforms of rat NKR-P1 lectin strongly discriminated between 9 and 10. 10 caused a 4-fold increase in killing of the NK resistant tumor cell lines at concentrations as low as 10(-8) M. Surprisingly, 11 interacted exclusively with the rat NKR-P1B isoform and inhibited efficiently natural killing in both rats and humans, even in the presence of the activating compounds 9 and 10. Dinitrophenol haptenization or influenza virus hemagglutinin T-cell epitope conjugation increased the immunogenicity of the parent compounds and resulted in the production of Tn specific antibodies.
The amount of European farm acreage devoted to organic foods has been increasing each year over the past three decades, as farmers strive to meet consumer demand for these products. To understand what factors drive this demand, researchers have focused on the end customers' perception of organic food and their motivations to purchase it. The standard research methods are questionnaires and literature review; however, these tend to be expensive, time consuming, or involve work with secondary data. This paper compares 14 studies carried out using standard research methods with the results of a social network analysis based on 344,231 posts by 73,380 Instagram users. The result of the comparison shows that in the case of organic food, the characteristic of "healthy" is the most important one to customers, both based on questionnaire surveys and the social network analysis. Moreover, based on these two analyses, 4 key areas can be identified as factors that are important to customers buying organic food: (1) health consciousness, (2) ecological motives, (3) tasty and (4) hedonism. As the results indicate, social network analysis can be considered a method with a high potential for gaining a greater insight into customers' perceptions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
