Vygotsky’s Analysis of Children’s Meaning Making Processes

Vygotsky’s work is extensive and covers many aspects of the development of children’s meaning-making processes in social and cultural contexts. However, his main focus is on the examination of the unification of speaking and thinking processes. His investigation centers on the analysis of the entity created by this unification - an internal speaking/thinking system with meaning at its center. Despite the fact that this speaking/thinking system is at the center of Vygotsky’s work, it remains little explored. This article relies on Vygotsky’s writings, particularlyThinking and Speech, to describe his examination of the speaking/thinking system. To analyze it he derives the unit -znachenie slova - “meaning through language.” InThinking and Speech Vygotsky describes the origins and development ofznachenie slova as a unit of the speaking/thinking system. He also details his genetic, functional, and structural analysis of the processes through which children internalize meaning in social interaction and organize it in an internal, psychological system. The foundation of this system is the child's ability to generalize by using symbolic representation in meaningful communication. Vygotsky’s analysis of the structure of generalization in the speaking/thinking system is central to his examination of how children make meaning of their sociocultural worlds

Combined MRI-PET dissects dynamic changes in plant structures and functions

Unravelling the factors determining the allocation of carbon to various plant organs is one of the great challenges of modern plant biology. Studying allocation under close to natural conditions requires non-invasive methods, which are now becoming available for measuring plants on a par with those developed for humans. By combining magnetic resonance imaging (MRI) and positron emission tomography (PET), we investigated three contrasting root/shoot systems growing in sand or soil, with respect to their structures, transport routes and the translocation dynamics of recently fixed photoassimilates labelled with the short-lived radioactive carbon isotope (11)C. Storage organs of sugar beet (Beta vulgaris) and radish plants (Raphanus sativus) were assessed using MRI, providing images of the internal structures of the organs with high spatial resolution, and while species-specific transport sectoralities, properties of assimilate allocation and unloading characteristics were measured using PET. Growth and carbon allocation within complex root systems were monitored in maize plants (Zea mays), and the results may be used to identify factors affecting root growth in natural substrates or in competition with roots of other plants. MRI-PET co-registration opens the door for non-invasive analysis of plant structures and transport processes that may change in response to genomic, developmental or environmental challenges. It is our aim to make the methods applicable for quantitative analyses of plant traits in phenotyping as well as in understanding the dynamics of key processes that are essential to plant performance
