personal Networks a tool for gaining insight into the transmission of knowledge about food and medicinal plants among tyrolean austrian migrants in australia brazil and peru
Journal of Ethnobiology and Ethnomedicine, 2014Co-Authors: Ruth Haselmair, Heidemarie Pirker, Elisabeth Kuhn, Christian R VoglAbstract:Background: Investigations into knowledge about food and medicinal plants in a certain geographic area or within a specific group are an important element of ethnobotanical research. This knowledge is context specific and dynamic due to changing ecological, Social and economic circumstances. Migration processes affect food habits and the knowledge and use of medicinal plants as a result of adaptations that have to be made to new surroundings and changing environments. This study analyses and compares the different dynamics in the transmission of knowledge about food and medicinal plants among Tyrolean migrants in Australia, Brazil and Peru. Methods: A Social Network Approach was used to collect data on personal Networks of knowledge about food and medicinal plants among Tyroleans who have migrated to Australia, Brazil and Peru and their descendants. A statistical analysis of the personal Network maps and a qualitative analysis of the narratives were combined to provide insight into the process of transmitting knowledge about food and medicinal plants. Results: 56 personal Networks were identified in all (food: 30; medicinal plants: 26) across all the field sites studied here. In both sets of Networks, the main source of knowledge is individual people (food: 71%; medicinal plants: 68%). The other sources mentioned are print and audiovisual media, organisations and institutions. Personal Networks of food knowledge are larger than personal Networks of medicinal plant knowledge in all areas of investigation. Relatives play a major role as transmitters of knowledge in both domains. Conclusions: Human sources, especially relatives, play an important role in knowledge transmission in both domains. Reference was made to other sources as well, such as books, television, the internet, schools and restaurants. By taking a personal Network Approach, this study reveals the mode of transmission of knowledge about food and medicinal plants within a migrational context.

A Social Network Approach to change detection in the interdependence structure of global stock markets
Social Network Analysis and Mining, 2013Co-Authors: Ram Babu Roy, Uttam Kumar SarkarAbstract:A novel method is proposed to rank the stock indices from across the globe to capture changes in the dominance of an index with respect to other indices. A correlation-based Network structure is formulated and centrality measures are used to track these changes. Temporal evolution of the minimum spanning tree derived from the Network of 93 stock indices worldwide has been analyzed with data from Bloomberg for the 5-year period from year 2006 through 2010. Measures are suggested for identifying dominant stock indices in the global stock market. It is investigated how the stock market turbulence can be detected by measuring the relative change in the ranks of the stock indices and in the Network centralization of the emergent Network structure. The study reveals how inclusion of abstract non-living entities such as stock indices in the Social Network analysis framework can capture the latent interdependence as manifested in the stock market. The chosen period of study encompassed the behavioral change in the stock market Network before and after the collapse of Lehman Brothers in the USA, revealing interesting counter-intuitive findings that the turbulence following the collapse of Lehman Brothers had a structure-loosening impact on the global stock market.

a Social Network Approach to examine the role of influential stocks in shaping interdependence structure in global stock markets
Advances in Social Networks Analysis and Mining, 2011Co-Authors: Ram Babu Roy, Uttam Kumar SarkarAbstract:This paper investigates the role of influential stocks in shaping the emergent system-level interdependence in global stock markets using a large set of stocks selected from major stock market indices from across the globe. We have proposed a method to identify influential stocks using various centrality measures used in Social Network analysis literature. Our study shows how these influential stocks provide key linkages in integrating the global stock markets as an interconnected system. We have also shown that the regional influence dominates over the economic sector influence in shaping the topological structure of stock market Network. The study also captures the change in the topology of this Network following the collapse of Lehman Brothers.
