| Mixed sediments are constituted of cohesive and non-cohesive materials with distinct behaviours that numerical models traditionally manage separately. This paper first introduces a rapid state of the Art in sediment transport modelling in order to point out the specific requirements for process-based models applied to mixed sediments. Based on a preliminary study by Waeles et al. (2007), which showed the validity of the advection approach to compute fine sand transport, a complete modelling strategy is described: it is applied to the suspended transport of sand and mud mixtures, and accounts for consolidation of mixed sediments. Special care is paid to the realistic representation of the structure and density of sand and mud mixtures, and to the... |

| The sediment characteristics of hydrate-bearing reservoirs profoundly affect the formation, distribution, and morphology of gas hydrate. The presence and type of gas, porewater chemistry, fluid migration, and subbottom temperature may govern the hydrate formation process, but it is the host sediment that commonly dictates final hydrate habit, and whether hydrate may be economically developed. In this paper, the physical properties of hydrate-bearing regions offshore eastern India (Krishna-Godavari and Mahanadi Basins) and the Andaman Islands, determined from Expedition NGHP-01 cores, are compared to each other, well logs, and published results of other hydrate reservoirs. Properties from the hydrate-free Kerala-Konkan basin off the west coast of India are... |

| Sediment transport modelling in estuarine environments, characterised by cohesive and non-cohesive sediment mixtures, has to consider a time variation of erodibility due to consolidation. Generally, validated by settling column experiments, mud consolidation is now fairly well simulated; however, numerical models still have difficulty to simulate accurately the sedimentation and consolidation of mixed sediments for a wide range of initial conditions. This is partly due to the difficulty to formulate the contribution of sand in the hindered settling regime when segregation does not clearly occur. Based on extensive settling experiments with mud-sand mixtures, the objective of this study was to improve the numerical modelling of mixed-sediment consolidation... |

| Processing plants in eight major food industries were highly productive before being acquired and they significantly improved their labor productivity afterward, Economic Research Service and U.S. Census Bureau researchers found in their analysis of Census data. The plant-level data on production inputs and costs provided a detailed picture of food-production facilities involved in mergers and acquisitions. The industries are meatpacking, meat processing, poultry slaughtering and processing, cheese making, fluid milk processing, flour milling, feed processing, and oilseed crushing. The analysis suggests that mergers and acquisitions contributed to the general improvement in labor productivity, echoing an earlier ERS study. Labor productivity is defined as... |

| Consolidation and structural changes in the food industry have had profound impacts on firms, employees, and communities in many parts of the United States. Over 1972-92, eight important food industries underwent a structural transformation in which the number of plants declined by about one-third and the number of employees needed to staff the remaining plants dropped by more than 100,000 (20 percent). The number of plants in one other industry also dropped, but that industry added jobs. Economists generally attribute structural changes such as these to rising or falling demand and shifts in technology. This report examines consolidation and structural change in meatpacking, meat processing, poultry slaughter and processing, cheese products, fluid milk,... |

| Napjainkban a világgazdaság egyik legfontosabb megoldásra váró problémája, hogy hogyan előzhető meg újabb globális pénzügyi és gazdasági válságok kialakulása, illetve léteznek-e olyan módszerek, eszközök, amelyek segítségével a már kialakult válságok hatásai, következményei mérsékelhetők. A módszerek, eszközök részben már rendelkezésre állnak, melyek közül célszerű kiemelni a konszern számvitel módszertanát, mert segítségével elkészíthető konszolidált éves beszámolót. E konszolidált éves beszámoló ugyanis alkalmas arra, hogy a konszerntagok közötti belső kapcsolatokból adódó halmozódásokat kiszűrve előmozdítsa a vállalatcsoportok reális megítélését. Segítségével elkerülhetővé válhat a – válság kialakulásában nagymértékben szerepet játszó – jogi, pénzügyi... |

| Mergers, acquisitions, and internal growth among grocery retailers, largely since 1996, have increased the share of grocery store sales accounted for by the largest 4, 8, and 20 food retailers nationwide. Similar consolidation is occurring among food wholesalers. At the same time, new packaged and branded produce items are gaining acceptance with consumers and vying for shelf space in the supermarket produce department. Growers, shippers, and their trade associations fear the possibility of fewer buyers for their products, particularly if new marketing and trade practices such as volume incentive rebates and slotting fees become widespread. This report uses data from the Censuses of Wholesale Trade and Retail Trade and industry sources to examine changes... |

| Consolidation in the agricultural biotechnology industry can both enhance and dampen market competition. This report examines the causes and consequences of industry consolidation and its effect on market efficiency. In some cases, concentration realizes economies of scale, which can improve market efficiency by driving down production costs. The protection of intellectual property rights is integral to the agricultural biotechnology marketplace, stimulating research and development, investment, and the development of substitute markets. However, excessively broad intellectual property rights can hinder the market for innovation. Recent data on mergers, acquisitions, and strategic collaborations in the agricultural biotechnology industry, as well as the... |

| Meatpacking consolidated rapidly in the last two decades: slaughter plants became much larger, and concentration increased as smaller firms left the industry. We use establishment-based data from the U.S. Census Bureau to describe consolidation and to identify the roles of scale economies and technological change in driving consolidation. Through the 1970's, larger plants paid higher wages, generating a pecuniary scale diseconomy that largely offset the cost advantages that technological scale economies offered large plants. The larger plants' wage premium disappeared in the 1980's, and technological change created larger and more extensive technological scale economies. As a result, large plants realized growing cost advantages over smaller plants, and... |

| In an era of rapid consolidation in banking, the effect of mergers on the availability of credit to agricultural businesses is unclear. Commercial bank mergers have profoundly altered the urban credit marketplace and are positioned to do the same for the agricultural credit marketplace. Adjustment models are estimated with data on independent bank consolidations from 1988 through 1995. The regression results bode well for agricultural lending if acquiring banks have larger concentrations of assets in agriculture than acquired banks. Conversely, if acquiring banks have smaller concentrations than acquired banks, acquisitions have a negative impact on agricultural lending. Since most acquiring banks have smaller agricultural loan concentrations than... |

| This paper examines the impact of farmland readjustment projects on farmland use and structural adjustment in Niigata, Japan. We use census data of rural communities for 1990 and 2000 to conduct pooled regression, first-difference, difference-in-differences, and propensity score matching estimations. We find positive impact of farmland readjustment projects in alleviating farmland abandonment and in facilitating outsourcing of agricultural works and farmland rental. The results suggest that farmland consolidation may be an effective option to resolve farmland fragmentation and to promote structural adjustment in concentrating farmland to efficient farmers which is a premise for strengthening the agricultural sector under economies of scale. |

| Despite extensive research and policy initiatives to increase the technical, financial, and managerial capacity of small drinking water systems, there has been little research focusing on understanding how consolidation can increase the overall capacity of the drinking water industry. Consolidation of water systems may be a mechanism that increases regulatory compliance by removing poorly performing systems from the industry and replacing inefficient management and/or capital. The US drinking water system is highly fragmented, with over 50,000 Community Water Systems (CWSs), of which the vast majority are classified as "small" by the US Environmental Protection Agency (EPA). A discrete choice model is employed to determine the characteristics shared by... |
