| Pressure-driven and temperature-driven transitions of two thermoresponsive polymers, poly(N-isopropylacrylamide) (pNIPAM) and poly(N-vinylisobutyramide) (pNVIBA)), in both a soluble linear polymer form and a cross-linked hydro-gel form, were examined by a dynamic light-scattering method and direct microscopic observation, respectively. Their behavior was compared with that of protein systems. Changes in some characteristic parameters in the time-intensity correlation functions of dynamic light-scattering measurement of aqueous solutions of pNIPAM at various pressures and temperatures showed no essential differences during temperature and pressure scanning and, as a whole, the motions of polymers in aqueous solutions were similar in two types of transitions... |

| Stored reserves are critical for the early spring growth of reproductive and vegetative sinks in sweet cherry (Prunus avium L.). To study the distribution of carbon storage reserves on new, highly productive hybrid rootstocks in sweet cherry, an experiment was established using 5-yr-old cv. 'Regina' on the semi-vigorous rootstock 'Gisela®6' ('GI®6'). Using whole-canopy enclosure chambers, five trees were pulse-labeled three times with high levels of 13CO2 during the fall. At leaf drop, leaves, buds, wood, bark and roots were sampled for gas chromatography-mass spectrometry (GC-MS) analysis. The storage organs with the highest percentages of excess 13C atoms were the roots and the older wood in the trunks, branches and buds. During the spring, newly... |

| This paper offers a novel interpretation of the introduction of floodplain rehabilitation and rural development into the water policy for the Tisza River in Hungary. It looks at the role of individuals and the strategies that they used to bring about water policy change. Five strategies are explored: developing new ideas, building coalitions to sell ideas, using windows of opportunity, playing multiple venues and orchestrating networks. Our discussion on the importance of each strategy and the individuals behind it is based on interviews, group discussions and a literature review. The international and political attention sparked by a series of floods, dike failure and a major cyanide spill, which preceded national elections, opened a window of opportunity... |

| Global environmental change requires responses that involve marked or qualitative changes in individuals, institutions, societies, and cultures. Yet, while there has been considerable effort to develop theory about such processes, there has been limited research on practices for facilitating transformative change. We present a novel pathways approach called Three Horizons that helps participants work with complex and intractable problems and uncertain futures. The approach is important for helping groups work with uncertainty while also generating agency in ways not always addressed by existing futures approaches. We explain how the approach uses a simple framework for structured and guided dialogue around different patterns of change by using examples. We... |

| Urban water governance regimes around the world have traditionally planned large-scale, centralized infrastructure systems that aim to control variables and reduce uncertainties. There is growing sectoral awareness that a transition toward sustainable alternatives is necessary if systems are to meet society’s future water needs in the context of drivers such as climate change and variability, demographic changes, environmental degradation, and resource scarcity. However, there is minimal understanding of how the urban water sector should operationalize its strategic planning for such change to facilitate the transition to a sustainable water future. We have integrated concepts from transitions, resilience, and institutional theory to develop a... |

| To understand milk processing systems in Caucasia and analyze their history，nine households of agro-pastoralists were surveyed in Georgia and Armenia. The techniques of clotting agent using series，fermented milk processing series and cream separating series ware broadly shared among agro-pastoralists over Georgia and Armenia. The characteristics of milk processing systems in Caucasia are 1) the milk processing techniques (clotting agent using series and fermented milk processing series) in Caucasia base on those techniques of West Asia，2) the cream separating series have developed in Caucasia because of its cooler natural environment，3) butter and butter-oil making by the technique of fermented milk processing series became unnecessary，thus the fermented... |

| This Discussion Paper focuses on developments of the agricultural sector in the federal states of the former Eastern Germany after German reunification. Descriptive analysis is involved to display problems of transition process and changes in agricultural production and structures. The results of the analysis report considerable differences in the agricultural sector between New and Old Federal States after 15 years after the reunification. These differences are especially to find in a variety of existing legal forms, considerably higher share of rented land, lower cattle stock as well as larger farm size of the farms in the New Federal States. Observed structural changes of the German agricultural sector display that due to European Union measures the... |

| The paper investigates theoretically and empirically the role of courts for contract enforcement in transition agriculture. In a survey of 306 Polish hog farmers conducted in 1999, only 38.5% of them reported to believe that they could use courts to enforce contracts with their most important customer. Furthermore, those who believe the legal system could be used would accept significant financial losses before taking action. We develop a theoretical model, based on the costs and benefits of court enforcement, which captures the boundary between contracts to be regarded as "enforceable" and "not-enforceable" and, simultaneously, the threshold of taking legal action. The empirical analysis strongly supports our model: (1) the farmers' responds can be... |

| With the collapse of the socialist regime in East Germany in late 1989 and the rising political call for unification in early 1990, a deep change of the institutional structure became necessary. The (agricultural) administration had to be totally restructured. This referred not only to substance, functions and tasks which had to be adjusted – similar to all other transition economies - to the market-economic and pluralistic democratic system, but also the whole administrative set-up had to be re-established in line with the West German system. Hence, a new administrative system had to be built up from scratch in the East, while the socialist one had to be dismantled in a short period. Overall, this institutional change seems to have been accomplished... |

| This paper is an extraction of some results achieved in a comprehensive study of Russia's transition in its regional as well as sectoral dimension. Thereby, the transition process between 1993 - 2000 has been approximated by aggregated developments of productivity, technical change, and technical efficiency which all have been calculated by a Stochastic Frontier Analysis (SFA). The obtained results have been analyzed with respect to any institutional circumstances in a second analytical step. Based on that, in a third step, some political call for actions have been specified as well as addressed according to regional/federal responsibility. The study has shown a notable heterogeneity within the considered regional as well as sectoral transition paths.... |

| Using only transition period data, this paper analyses revealed comparative advantages (RCAs) and specialisations to identify the 3-digit SITC (Standard International Trade Classification) sectors in which the EUs trade liberalisation with Eastern European applicants may represent opportunities or competition between them and EU South. First, during the transition period potential competition occurs in labour-intensive sectors. Over one-third of Eastern European and EU South exports overlap both in the labour-intensive factor content and in the destination market (EU North). Second, the clothing and footwear export unit values of Visegrad countries are very close to those of EU South, indicating similar quality levels. Third, the greatest potential... |
