Role of eIntermediaries in the United States Paper Supply Chain

Kallioranta, Sanna Maria 08 April 2003 (has links)
In an attempt to streamline the paper supply chain, paper industry vertical business-to-business eMarketplaces were established to help industry players to decrease inefficiencies in their supply chains, to minimize negative effects of economic cyclicality, and to achieve better visibility. eMarketplaces rode the hype of revolutionizing the way in which industries conduct business, citing the cost savings achieved by expanded market reach, operational efficiencies, aggregated purchasing, and finding the least expensive suppliers. Adoption of eIntermediaries has been lower than expected in the paper industry and many of the paper vertical start-ups failed when the economy softened and the dot.com bubble burst. This thesis examines the expectations, experience and role of eIntermediaries in the paper supply chain. eIntermediaries failed to fulfill paper suppliers expectations regarding key promises, such as improving cash flow, reducing cycle time, and reducing errors. None of the paper supplier respondents achieved the expected benefits from eIntermediary implementation. Overall paper suppliers lack commitment and trust for eIntermediaries. Paper buyer and paper supplier attitudes and expectations on eIntermediaries do not differ significantly. Both suppliers and buyers are concerned that using eIntermediaries would lead to loss of contact with exchange partners, but paper suppliers have a greater level of concern. Suppliers are most concerned with profitability, security of sensitive information, technical resources, costs, and the need to restructure established business processes in the context of using eIntermediaries. B2B exchanges seem to have underestimated the complexity of the paper industry and overestimated companies ability to adopt eCommerce. Organizational changes, changes in business processes, development of industry standards, and improvements in integration technology systems are all needed to capture benefits from B2B exchanges.

The Influence of Different Ground Cover Treatments on the Growth of Outplanted Seedlings on Remined Sites in Eastern Tennessee

Rizza, John J 01 May 2007 (has links)
There is growing interest in the reforestation of surface mined lands for the production of valuable forest products and creation of quality wildlife habitat. These objectives can be met by planting native woody and herbaceous species on reclaimed surface mines. However, in this region, many of the common ground cover species used to reduce erosion, compete aggressively with tree seedlings, preventing successful establishment. A research project was designed with two main objectives: to investigate the growth and survival of tree seedlings across different herbaceous ground cover treatments, and to identify the relationship between the growth and function of tree seedlings and microsite variables. Five tree species, native to the eastern hardwood forest surrounding the mine site, were planted in 2005. They are: yellow poplar (Liriodendron tulipifera), sugar maple (Acer saccharum), northern red oak (Quercus rubra), eastern redbud (Cercis canadensis), and Virginia pine (Pinus virginiana). Five different ground cover treatments were applied within four replicated planting areas. Two treatments consisted of two different native warm season grass mixes, two were standard reclamation mixes, and one was an unseeded control. Growth and survival, seedling transpiration rate, light measurements, soil respiration, groundcover biomass, and soil chemical properties were measured and analyzed. Survival was significantly different across tree species, with sugar maple having the best overall survival and yellow-poplar the poorest. Seedling survival tended to be greatest within the native warm season grass treatments; however growth rates were variable between all treatments. Seedling survival and growth was related to the amount of herbaceous cover suggesting that tree species react differently to the conditions associated with the surrounding level of herbaceous cover. Moderate ground cover resulted in the best survival, while bare ground or full cover demonstrated the poorest survival rates for northern red oak and eastern redbud. Sugar maple transpiration rate was significantly greater in the moderate (50-75%) cover class during the second growing season. Soil chemical concentrations differed significantly between years, but not between treatments. Soil respiration significantly increased during the two years of this study. The results suggest that moderate herbaceous cover is advantageous for the establishment tree seedlings.
