Internetnutzung in der deutschen Agrarwirtschaft: Online-Handelsportale als neue Organisationsform

This paper describes the concept of E-commerce portals, so called E-hubs, in its basic characteristics and analyses their potential impacts on agribusiness enterprises and agricultural markets. Since these impacts depend on the level of market penetration of this new type of organisation, it is further attempted to identify the most relevant factors that determine future acceptance and utilisation of internet portals at sector and enterprise level.E-commerce, agriculture, farm trade, Farm Management, Research and Development/Tech Change/Emerging Technologies,

Führungsverhalten beziehungsweise Führungsstile in Agrarunternehmen

The development of the relationship between employer and employee is an important aspect of management, i. e. management behaviour and management style play an important role with regard to the employee as a critical factor for success. Increasing average sizes of agricultural enterprises and numbers of employees and the missing hierarchical structures create the need for additional motivation opportunities. In the agricultural sector the quality performance of labour activities is difficult to control, therefore, it becomes even more important to discuss management behaviour and management styles. Management styles are mainly described theoretically in the literature but rarely for agricultural enterprises. An empirical study demonstrates that in practice agricultural entrepreneurs are aware of numerous management styles. Although various standard management styles are known to the managers, the successful manager quickly adapts his individual management style to the current situation.management behaviour, management styles, Farm Management, Labor and Human Capital,

MicroRNA expression profiles during cotton (Gossypium hirsutum L) fiber early development

The role of microRNAs (miRNAs) during cotton fiber development remains unclear. Here, a total of 54 miRNAs belonging to 39 families were selected to characterize miRNA regulatory mechanism in eight different fiber development stages in upland cotton cv BM-1. Among 54 miRNAs, 18 miRNAs were involved in cotton fiber initiation and eight miRNAs were related to fiber elongation and secondary wall biosynthesis. Additionally, 3,576 protein-coding genes were candidate target genes of these miRNAs, which are potentially involved in cotton fiber development. We also investigated the regulatory network of miRNAs and corresponding targets in fiber initiation and elongation, and secondary wall formation. Our Gene Ontology-based term classification and KEGG-based pathway enrichment analyses showed that the miRNA targets covered 220 biological processes, 67 molecular functions, 45 cellular components, and 10 KEGG pathways. Three of ten KEGG pathways were involved in lignan synthesis, cell elongation, and fatty acid biosynthesis, all of which have important roles in fiber development. Overall, our study shows the potential regulatory roles of miRNAs in cotton fiber development and the importance of miRNAs in regulating different cell types. This is helpful to design miRNA-based biotechnology for improving fiber quality and yield
