The son of a Lithuanian artist, Antanas Mockus was the president of the National University in Colombia before he became mayor of Bogota in 1995. As mayor, he transformed the city into a huge classroom, not only bringing to his administration a new view of governing but also transforming the way people exercised their citizenship. Mockus resorted…

Investigation of bioarcheological material of ancient human populations allows us to understand the subsistence behavior associated with various adaptations to the environment. Feeding habits are essential to the survival and growth of ancient populations. Stable isotope analysis is accepted tool in paleodiet (Schutkowski et al, 1999) and paleoenvironmental (Zernitskaya et al, 2014) studies. However, stable isotopes can be useful not only in investigating human feeding habits but also in describing social and cultural structure of the past populations (Le Huray and Schutkowski, 2005). Only few stable isotope investigations have been performed before in Lithuanian region suggesting a quite uniform diet between males and females and protein intake from freshwater fish and animal protein. Previously, stable isotope analysis has only been used to study a Stone Age population however, more recently studies have been conducted on Iron Age and Late medieval samples (Jacobs et al, 2009). Anyway, there was a need for more precise examination. Stable isotope analysis were performed on human bone collagen and apatite samples in this study. Data represented various ages (from 5-7th cent. to 18th cent.). Stable carbon and nitrogen isotope analysis on medieval populations indicated that individuals in studied sites in Lithuania were almost exclusively consuming C3 plants, C3 fed terrestrial animals, and some freshwater resources. Current investigation demonstrated social differences between elites and country people and is promising in paleodietary and daily life reconstruction. Acknowledgement I thank prof. dr. G.

horizons to production processing (Koroleva et al). The use of femtosecond lasers enables polymerization for flexible production of micro-optics and integrated optics (Malinauskas et al). Laser beams of moderate intensity are used to create surface relief patterning in polymer and hybrid matter (Babeva et al) while the use of optimized acrylamide photopolymers results in submicron holographic structures (Trainer et al). In a different concept, the application of laser radiation forces in soft polymer matter offers intriguing, yet unexplored, means for the organization of dense structures and filaments in polymer solutes, pointing to nonlinear optical applications (Anyfantakis et al). Finally, high laser intensities are used for the processing of soft polymer and hybrid matter. In the two modes of operation available, laser-induced forward transfer of polymers is a promising alternative for the creation of controlled structures (Palla-Papavlu et al), while ablative structuring creates interfaces with enhanced properties by excimer laser irradiation at the deep ultraviolet 193 nm and 157 nm wavelengths (Athanasekos et al). Such methods provide flexible tools for the fabrication of optimized photonic sensor structures based on hybrid nanocomposites incorporating diffractive optic interfaces, a technology enabling the recent advent of remote point sensing of chemical and physical agents by light (Vasileiades et al). A substantial part of this work has been supported in the framework of COST MP0604 Action `Optical Micro-Manipulation by Nonlinear Nanophotonics' of the European Science Foundation. We are confident that this collection of papers on light-induced material organization will guide the reader in this emerging field, inspire the interested scientific community and stimulate further research and innovation in this exciting and growing field.
