What Does Today's Image Record.
Yu, Xiang ; DVOŘÁK, Tomáš (vedoucí práce) ; ŠIMŮNEK, Michal (oponent)
The thesis describes and analyses post-documentary photography with emphasis on contemporary Chinese theory and practice. The traditionally defined documentary function of photography has been challenged on many sides and the technology growth of the new media has caused the structural change of photographic language. Documentary function, the core characteristics of photographic language, is rapidly falling apart in this change. As an imported tool, photography has taken a special road in its growth in China. For well known ideology reasons, the documentary function of photography has displayed some very peculiar changes in its traditional past as well as in globalized China today. This paper will try to analyze various causes that influence the documentary function of photography, compare political and cultural differences and show the post-documentary characteristics of contemporary Chinese photography.

Projections of future water-energy-vegetation regimes at the Lysina catchment, Czech Republic

Hydrologic models represent useful tools for the understanding of forest hydrological functions. At the Lysina Critical Zone Observatory (50°03’ N, 12°40’ E; area 0.293 km2), a forest catchment in the western Czech Republic, a distributed physics-based hydrologic model, the Penn State Integrated Hydrologic Model (PIHM), was used to simulate long-term hydrological change under forest management practices, and to evaluate the comparative scenarios of the hydrological consequences under anticipated climate change. Stand age-adjusted LAI (leaf area index) curves were generated from an empirical relationship to represent changes in seasonal tree growth. By considering the age-adjusted LAI, the spatially distributed model was able to successfully simulate the integrated hydrologic response from snow melt, recharge, evapotranspiration, groundwater levels, soil moisture and streamfl ow, as well as spatial patterns of each hydrologic state and fl ux variables. Corrected climatic data from the ALADIN-Climate/CZ regional climate model with SRES A1B scenario and diff erent forest age categories (Norway spruce monoculture) were used for projection of hydrologic pattern shift at the study site in the future (2025–2050, 2071–2100). Th e model projections suggested that that the decrease in mean annual runoff would be from 422 mm (observed in 1990–2011) to 361 mm (2021–2100) and 345 mm (2071–2100) with notable changes in seasonal patterns represented by a runoff decrease in the spring and summer months.
