CO2 and O2 exchange rates, chlorophyll fluorescence and P700 oxidation (absorption at 830 nm) were recorded in Helianthus amuus L. leaves grown in soil in a growth cabinet. Phase-portraits of CO2 exchange rate plotted against three other parameters were ušed to interpret control of electron transport during photosynthesis oscillations, initiated by transfer from air to the saturating CO2. Plots of the CO2 exchange rate vs. P700 revealed that the P700 part which remained oxidized was almost proportional to CO2 exchange rate during both the ascending and descending phase of oscillations.
When reflecting on the symbolic integration of migrants into their host societies, sociological and anthropological discourses are challenged by the fact that recent migrants do not simply leave their homelands behind but make great efforts to maintain their attachments at a distance. In this article the authors examine a transnational migrant network of eight highly educated young women from the post-socialist region of southern Slovakia and devote special attention to the construction of their diasporic identity and shared life-world. They interpret the migration of these highly educated people not as a rupture but as a coherent continuation of their life course. In order to understand their recent biographical situation, it is necessary to consider the role that a particular form of habitus plays in migration. The authors claim that the experience of living in the culturally hybrid life-world of Czechoslovak Hungarians has played an important role in shaping their ability to live in the dual world of migrants.
