Performance- and value-oriented decision support for supply chain configuration

Brandenburg, M. ., Kuhn, H. ., Schilling, R. ., & Seuring, S. . (2014). Performance- and value-oriented decision support for supply chain configuration. Logistics Research, 7(1), 16. http://doi.org/10.1007/s12159-014-0118-8

Abstract

The task of supply chain (SC) configuration is to establish a product-specific SC for new products. Apart from cross-regional network aspects and inter-disciplinary factors, the problem complexity is driven by dynamics and uncertainties of short product life cycles. SC configuration affects SC performance and value creation. Hence, resulting impacts have to be measured and compared under consideration of dynamics and uncertainties. In the conceptual part of this paper, dynamics and uncertainties of SC configuration are integrated into a conceptual framework for value-based supply chain management. In the model-based part of this paper, this framework is linked to a discrete-event simulation model. The performance outcomes and value impacts of SC configuration options are empirically assessed in a case study of a fast-moving consumer goods manufacturer. The shortfalls of cost-focused decision-making without consideration of capital-related factors and non-financial aspects are illustrated.

Calcarides A?E, Antibacterial Macrocyclic and Linear Polyesters from a Calcarisporium Strain

Silber, J. ., Ohlendorf, B. ., Labes, A. ., Erhard, A. ., & Imhoff, J. F. (2013). Calcarides A?E, Antibacterial Macrocyclic and Linear Polyesters from a Calcarisporium Strain. Marine Drugs, 11, 3309–3323. Abgerufen von http://oceanrep.geomar.de/21998/ (Original work published 2025)

Abstract

Bioactive compounds were detected in crude extracts of the fungus, Calcarisporium sp. KF525, which was isolated from German Wadden Sea water samples. Purification of the metabolites from the extracts yielded the five known polyesters, 15G256\ensuremath\alpha, \ensuremath\alpha-2, \ensuremath\beta, \ensuremath\beta-2 and \ensuremath\pi (1?5), and five new derivatives thereof, named calcarides A?E (6?10). The chemical structures of the isolated compounds were elucidated on the basis of one- and two-dimensional NMR spectroscopy supported by UV and HRESIMS data. The compounds exhibited inhibitory activities against Staphylococcus epidermidis, Xanthomonas campestris and Propionibacterium acnes. As the antibacterial activities were highly specific with regard to compound and test strain, a tight structure-activity relationship is assumed.

Integrated Therapy Safety Management System

Podtschaske, B. ., Fuchs, D. ., & Friesdorf, W. . (2013). Integrated Therapy Safety Management System. British Journal of Clinical Pharmacology, 76(Suppl 1), 5–13. http://doi.org/https://doi.org/10.1111/bcp.12155 (Original work published September 2013)

Abstract

The aim is to demonstrate the benefit of the medico-ergonomic approach for the redesign of clinical work systems. Based on the six layer model, a concept for an ‘integrated therapy safety management’ is drafted. This concept could serve as a basis to improve resilience. Methods The concept is developed through a concept-based approach. The state of the art of safety and complexity research in human factors and ergonomics forms the basis. The findings are synthesized to a concept for ‘integrated therapy safety management’. The concept is applied by way of example for the ‘medication process’ to demonstrate its practical implementation. Results The ‘integrated therapy safety management’ is drafted in accordance with the six layer model. This model supports a detailed description of specific work tasks, the corresponding responsibilities and related workflows at different layers by using the concept of ‘bridge managers’. ‘Bridge managers’ anticipate potential errors and monitor the controlled system continuously. If disruptions or disturbances occur, they respond with corrective actions which ensure that no harm results and they initiate preventive measures for future procedures. The concept demonstrates that in a complex work system, the human factor is the key element and final authority to cope with the residual complexity. The expertise of the ‘bridge managers’ and the recursive hierarchical structure results in highly adaptive clinical work systems and increases their resilience. Conclusions The medico-ergonomic approach is a highly promising way of coping with two complexities. It offers a systematic framework for comprehensive analyses of clinical work systems and promotes interdisciplinary collaboration.

Calcaripeptides A?C, Cyclodepsipeptides from a Calcarisporium Strain

Silber, J. ., Ohlendorf, B. ., Labes, A. ., Näther, C. ., & Imhoff, J. F. (2013). Calcaripeptides A?C, Cyclodepsipeptides from a Calcarisporium Strain. Journal of Natural Products, 76, 1461–1467. Abgerufen von http://oceanrep.geomar.de/21997/ (Original work published Juli 2013)

Abstract

The isolation and structure elucidation of the novel calcaripeptides A (1), B (2), and C (3) and studies on their biosynthetic origin are described. The calcaripeptides were identified from Calcarisporium sp. strain KF525, which was isolated from the German Wadden Sea. Compounds 1?3 are macrocyclic structures composed of a proline and a phenylalanine residue as well as a nonpeptidic substructure. Structure elucidation was achieved by applying one- and two-dimensional NMR spectroscopy supported by high-resolution mass spectrometry. X-ray crystallography was performed to determine the relative configuration of 1. The absolute configuration of 1 was assigned by HPLC of the amino acids after hydrolysis of the molecule and derivatization with chiral agents. Studies on the biosynthesis by feeding 13C-labeled substrates revealed that the nonpeptidic part of 1 originates from acetate and l-methionine. The involvement of a hybrid between a polyketide synthase and a nonribosomal peptide synthetase in the biosynthesis of the calcaripeptides is discussed.
