| 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... |

| 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... |

| This study examines Food Stamp Program (FSP) participation patterns with an emphasis on macroeconomic effects and age differences. Entry into and exit out of the program are examined with data from the Survey of Income and Program Participation 2004 panel using probit techniques. The results indicate that young adults easily enter the FSP but quickly move out. Older people are hesitant to enter the FSP but they stay on longer compared to their younger counterparts. The estimation results confirm the common belief that economic dynamics and FSP participation are negatively related. When the unemployment rates rise, the likelihood of entry and continuation on food stamps increases. This study also documents that the macroeconomic effects on FSP transitions... |

| A key objective of China's reform program was to reduce distortions in the economic system and enhance growth. However, when implemented in incremental and partial ways, local governments or individuals have chance to capture rents inherent in the reform process. Young (2000) warned that the rent-seeking behavior might lead to increasing market fragmentation. Empirical studies have since shown that this did not happen in the product markets. In this paper we argue that as rents from the product markets were squeezed out during the reform process, rent-seeking behavior shifted to the factor markets, especially the capital and land markets. The reform process now needs to be deepened to ensure that the factor markets also become more integrated and efficient. |

| Prior to the EU accession Polish agricultural sector was experiencing serious structural problems. Not surprisingly Polish agricultural negotiations with EU were the toughest. Polish officials wanted to convince domestic rural electorate that the farms will operate on the competitive basis in enlarged EU. This paper investigates, however, how the competitiveness has been evolving yet prior to the accession, given the strong pressures within which it had to operate. We asked if Polish farms were responsive to this pressure - that is whether they were able to increase their productivity sufficiently to counter negative forces at work and maintain their competitiveness. The research showed a gloomy picture of declining farm productivity together with... |

| 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... |

| Land reform started in Ukraine 14 years ago became one of the most important issues in transformation of large state agricultural enterprises into market oriented agricultural enterprises. Significant changes in land use and land ownership has happened as a result of land reform implementation in Ukraine. Namely, state monopoly on land was eliminated, agricultural land was privatized, citizens of Ukraine received land plots in possession, first land transactions have happened at agricultural land market etc. Actual data regarding Ukrainian land relations reformation is systematized in this Discussion paper with especial focus on establishing the prerequisites of further formation and perspective development of the agricultural land market in Ukraine.... |

| The possibility for self-financing in agriculture is very small, primarily due to lower labour productivity leading to lower rate of surplus value. Therefore, in the development of Serbian agriculture, special importance is attached to other sources of financing such as: the Agrarian budget, i.e. credits of the Ministry of Agriculture, Forestry and Water Management; credits of business banks; development funds; leasing companies. With the reconstruction of the Serbian banking system in 1994, the primary issue, as an important source for financing agriculture used primarily for current reproduction, was abandoned. Due to transition to a market economy system and cancellation of financing from the primary issue, economic entities in agriculture have found... |

| 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... |

| 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... |

| This study tests the theory of rationing, examining changes in household consumption behavior during the transition to a market economy in Poland, 198792. A model of consumption under rationing is developed and fitted to prereform quarterly data from the Polish Household Budget Survey. Virtual prices, prices at which consumers would have voluntarily chosen the rationed levels of goods, are derived for food and housing. The prereform Almost Ideal Demand System (AIDS) model with rationing is estimated. Estimates from the virtual AIDS yield plausible values for price and income elasticities. The AIDS model (without rationing) is also fitted to postreform quarterly household survey data for comparison and evaluation. When the two sets of results are compared,... |
