Impacts of supply chain management on company value: benchmarking companies from the fast moving consumer goods industry

Brandenburg, M. ., & Seuring, S. . (2011). Impacts of supply chain management on company value: benchmarking companies from the fast moving consumer goods industry. Logistics Research, 3(4), 233–248. http://doi.org/10.1007/s12159-011-0056-7

Abstract

The research question addressed is to which extent supply chain management (SCM) creates value from cost and working capital. The paper provides an empirical evaluation including insights on important criteria for value creation. In a secondary data analysis, 10 leading fast moving consumer goods (FMCG) companies are benchmarked regarding the value created from cost of goods sold (COGS) and working capital within the time horizon 2003–2008. The study applies benchmarking methodology and a discounted cash flow (DCF) based model for quantifying value contributions. It is shown that SCM is realized in a value-adding way with different emphasis on COGS or working capital. Monetarily working capital components (trade payables, trade receivables) have a high relevance for value creation. Continuous improvements and long lasting developments of value drivers are more appropriate for value creation than alternating improvements and deteriorations. Timing aspects of value driver developments have to be considered for value creation. The value of the paper stems from empirical comparison of value created by working capital and COGS and from evidence of important criteria for value creation. Further analysis based on cost components as well as benchmarking with different or extended content, such as fixed asset performance or cross-industry benchmarking, leave room for future research.

Informatics in Radiology: Use of a C-Arm Fluoroscopy Simulator to Support Training in Intraoperative Radiography

Bott, O. ., Dresing, K. ., Wagner, M. ., Raab, B.-W. ., & Teistler, M. . (2011). Informatics in Radiology: Use of a C-Arm Fluoroscopy Simulator to Support Training in Intraoperative Radiography. RadioGraphics, 31, E65-E75. http://doi.org/10.1148/rg.313105125

Abstract

Mobile image intensifier systems (C-arms) are used frequently in orthopedic and reconstructive surgery, especially in trauma and emergency settings, but image quality and radiation exposure levels may vary widely, depending on the extent of the C-arm operator s knowledge and experience. Current training programs consist mainly of theoretical instruction in C-arm operation, the physical foundations of radiography, and radiation avoidance, and are largely lacking in hands-on application. A computer-based simulation program such as that tested by the authors may be one way to improve the effectiveness of C-arm training. In computer simulations of various scenarios commonly encountered in the operating room, trainees using the virtX program interact with three-dimensional models to test their knowledge base and improve their skill levels. Radiographs showing the simulated patient anatomy and surgical implants are “reconstructed” from data computed on the basis of the trainee s positioning of models of a C-arm, patient, and table, and are displayed in real time on the desktop monitor. Trainee performance is signaled in real time by color graphics in several control panels and, on completion of the exercise, is compared in detail with the performance of an expert operator. Testing of this computer-based training program in continuing medical education courses for operating room personnel showed an improvement in the overall understanding of underlying principles of intraoperative radiography performed with a C-arm, with resultant higher image quality, lower overall radiation exposure, and greater time efficiency.

Bio-mining the microbial treasures of the ocean: New natural products

Imhoff, J. F., Labes, A. ., & Wiese, J. . (2011). Bio-mining the microbial treasures of the ocean: New natural products. Biotechnology Advances, 29, 468–482. Abgerufen von http://oceanrep.geomar.de/12044/

Abstract

The biological resources of the oceans have been exploited since ancient human history, mainly by catching fish and harvesting algae. Research on natural products with special emphasis on marine animals and also algae during the last decades of the 20th century has revealed the importance of marine organisms as producers of substances useful for the treatment of human diseases. Though a large number of bioactive substances have been identified, some many years ago, only recently the first drugs from the oceans were approved. Quite astonishingly, the immense diversity of microbes in the marine environments and their almost untouched capacity to produce natural products and therefore the importance of microbes for marine biotechnology was realized on a broad basis by the scientific communities only recently. This has strengthened worldwide research activities dealing with the exploration of marine microorganisms for biotechnological applications, which comprise the production of bioactive compounds for pharmaceutical use, as well as the development of other valuable products, such as enzymes, nutraceuticals and cosmetics. While the focus in these fields was mainly on marine bacteria, also marine fungi now receive growing attention. Although culture-dependent studies continue to provide interesting new chemical structures with biological activities at a high rate and represent highly promising approaches for the search of new drugs, exploration and use of genomic and metagenomic resources are considered to further increase this potential. Many efforts are made for the sustainable exploration of marine microbial resources. Large culture collections specifically of marine bacteria and marine fungi are available. Compound libraries of marine natural products, even of highly purified substances, were established. The expectations into the commercial exploitation of marine microbial resources has given rise to numerous institutions worldwide, basic research facilities as well as companies. In Europe, recent activities have initiated a dynamic development in marine biotechnology, though concentrated efforts on marine natural product research are rare. One of these activities is represented by the Kieler Wirkstoff-Zentrum KiWiZ, which was founded in 2005 in Kiel (Germany).
