What is the impact of company specific adjustments on the acceptance and diffusion of logistic standards?

Transportation Networks and Logistics 4.0 work on the basis of integrated systems. These systems are enabled by standards which are widely used for the communication between IT-Systems. Due to individual requirements, standards are customized by companies. The extent of individualization has not yet been investigated. Therefore, we applied an empirical analysis on two mature logistic communication standards to identify the standard-application gap by calculating the interoperability between the applied standards. Within these results, we expand the standardization theory by simulating the network effects and the standard diffusion and quantify the impact of the company specific individualization of logistic standards. The identified findings help to improve the standard diffusion model and to improve the development of logistic standards

A Platform Business Model for Collaborative Additive Manufacturing

Modern manufacturing is caught in a trade-off between maximizing efficiency and staying flexible in dynamic markets. Inter-organizational sharing of manufacturing capacities on a digital marketplace could contribute to gain flexibility, reduce cost and capital employed as well as provide further business opportunities. Although current research has already prepared the ground for its technical conceptualization, research on such a marketplace’s implementation in a business model is scarce. However, since an efficient matching of supply and demand requires a sufficient number of platform users, attracting corporate customers with a suitable business model is crucial. The present research aims to address this problem by developing and evaluating a business model for a marketplace provider, illustrated for the case of additive manufacturing

Requirements and a Meta Model for Exchanging Additive Manufacturing Capacities

In an environment shaped by digital transformation and globalization, manufacturers face increasing market dynamics, cost pressure, and more sophisticated customer requirements. As this demands flexibility and adaptability, enterprises rely on new solutions for collaboration. A marketplace for production capacities supports companies in reducing order risks and improving responsiveness to changing market conditions. We seek to define requirements for a marketplace that is capable of matching products with production processes. With an initial focus on additive manufacturing, we aim to build a blueprint for similar application scenarios in other industrial contexts. Therefore, we employ a qualitative research based on expert interviews. Our results suggest that a marketplace for production capacities must address various requirements, which can be grouped under the categories of technologies, machines, and products. We further build a conceptual meta model that sets the groundwork for the matching and thus facilitates the implementation of the marketplace in practice

Size tunable visible and near-infrared photoluminescence from vertically etched silicon quantum dots

Corrugated etching techniques were used to fabricate size-tunable silicon quantum dots that luminesce under photoexcitation, tunable over the visible and near infrared. By using the fidelity of lithographic patterning and strain limited, self-terminating oxidation, uniform arrays of pillar containing stacked quantum dots as small as 2 nm were patterned. Furthermore, an array of pillars, with multiple similar sized quantum dots on each pillar, was fabricated and tested. The photoluminescence displayed a multiple, closely peaked emission spectra corresponding to quantum dots with a narrow size distribution. Similar structures can provide quantum confinement effects for future nanophotonic and nanoelectronic devices

Myelodysplastic syndromes: Aspects of current medical care and economic considerations in Germany

Myelodysplastic syndromes (MDS) are a heterogeneous group of diseases mainly affecting older people. The use of an increasing number of therapeutic options depends on a systematic risk stratification of the patients. A high percentage of MDS patients need blood transfusions as supportive care, which influence quality of life and cause a great part of the costs generated by MDS therapy. In this article which is based on a workshop about the burden of MDS held in October 2006 in Munich, MDS is discussed with regard to different aspects: current therapies, transfusion medicine, geriatrics, quality of life, and health economic aspects

Multiple sulphur and iron isotope composition of detrital pyrite in Archaean sedimentary rocks : a new tool for provenance analysis

Author Posting. © The Author(s), 2009. This is the author's version of the work. It is posted here by permission of Elsevier B.V. for personal use, not for redistribution. The definitive version was published in Earth and Planetary Science Letters 286 (2009): 436-445, doi:10.1016/j.epsl.2009.07.008.Multiple S (δ34S and δ33S) and Fe (δ56Fe) isotope analyses of rounded pyrite grains from 3.1 to 2.6 Ga conglomerates of southern Africa indicate their detrital origin, which supports anoxic surface conditions in the Archaean. Rounded pyrites from Meso- to Neoarchaean gold and uranium-bearing strata of South Africa are derived from both crustal and sedimentary sources, the latter being characterised by non-mass dependent fractionation of S isotopes (Δ33S as negative as -1.35‰) and large range of Fe isotope values (δ56Fe between -1.1 and 1.2‰). Most sediment-sourced pyrite grains are likely derived from sulphide nodules in marine organic matter-rich shales, sedimentary exhalites and volcanogenic massive sulphide deposits. Some sedimentary pyrite grains may have been derived from in situ sulphidised Fe-oxides, prior to their incorporation into the conglomerates, as indicated by unusually high positive δ56Fe values. Sedimentary sulphides without significant non-mass dependent fractionation of S isotopes were also present in the source of some conglomerates. The abundance in these rocks of detrital pyrite unstable in the oxygenated atmosphere may suggest factors other than high pO2 as the cause for the absence of significant non-mass dependent fractionation processes in the 3.2 – 2.7 Ga atmosphere. Rounded pyrites from the ca. 2.6 Ga conglomerates of the Belingwe greenstone belt in Zimbabwe have strongly fractionated δ34S, Δ33S and δ56Fe values, the source of which can be traced back to black shale-hosted massive sulphides in the underlying strata. The study demonstrates the utility of combined multiple S and Fe isotope analysis for provenance reconstruction of Archaean sedimentary successions.AH acknowledges support by NAI International Collaboration Grant and NRF grant FA2005040400027.

PBM Implementation Group, Making patient blood management the new norm(al) as experienced by implementors in diverse countries

Background: Patient blood management (PBM) describes a set of evidence-based practices to optimize medical and surgical patient outcomes by clinically managing and preserving a patient's own blood. This concepts aims to detect and treat anemia, minimize the risk for blood loss and the need for blood replacement for each patient through a coordinated multidisciplinary care process. In combination with blood loss, anemia is the main driver for transfusion and all three are independent risk factors for adverse outcomes including morbidity and mortality. Evidence demonstrates that PBM significantly improves outcomes and safety while reducing cost by macroeconomic magnitudes. Despite its huge potential to improve healthcare systems, PBM is not yet adopted broadly. The aim of this study is to analyze the collective experiences of a diverse group of PBM implementors across countries reflecting different healthcare contexts and to use these experiences to develop a guidance for initiating and orchestrating PBM implementation for stakeholders from diverse professional backgrounds. Methods: Semi-structured interviews were conducted with 1-4 PBM implementors from 12 countries in Asia, Latin America, Australia, Central and Eastern Europe, the Middle East, and Africa. Responses reflecting the drivers, barriers, measures, and stakeholders regarding the implementation of PBM were summarized per country and underwent qualitative content analysis. Clustering the resulting implementation measures by levels of intervention for PBM implementation informed a PBM implementation framework. Results: A set of PBM implementation measures were extracted from the interviews with the implementors. Most of these measures relate to one of six levels of implementation including government, healthcare providers, funding, research, training/education, and patients/public. Essential cross-level measures are multi-stakeholder communication and collaboration. Conclusion: The implementation matrix resulting from this research helps to decompose the complexity of PBM implementation into concrete measures on each implementation level. It provides guidance for diverse stakeholders to design, initiate and develop strategies and plans to make PBM a national standard of care, thus closing current practice gaps and matching this unmet public health need
