Vernetzte Kreativität - Menschzentrierte Gestaltung und Integration einer Community-Plattform für Innovationsimpulse = Connected Creativity - Human Centred Design and Integration of a Community Platform for Innovation Impulses

In der vorliegenden Arbeit werden Handlungsempfehlungen zur Gestaltung und Integration einer Community-Plattform für Innovationsimpulse aus einer Fallstudie abgeleitet. Basis bildet eine theoretische Untersuchung von Humanfaktoren im Kontext von Innovationsimpulsen. Im Kern der Arbeit werden diese Faktoren durch Interviews und eine Befragung detailliert. Auf diesen Erkenntnissen wird ein Prototyp einer Plattform gestaltet, in einer Organisation eingeführt und genutzt

Einflussfaktoren auf die Bondemissionsprämie im Bereich der alternativen Energien: Eine Note

Determinants of Bond Issuance Spreads for Alternative Energy Firms: A NoteThe following analysis presents empirical evidence on the investor demanded risk premium at the bond issuance. The sample consists of bonds issued by alternative energy firms in Germany between 2008 and 2012. Our results show that besides the well-known influence of ratings, other factors may significantly influence bond spreads. As the size of the issue and the denomination increases, the yield spread decreases. Thus apparently, large issue sizes directed towards institutional investors are capable to benefit from favorable bond issues in the past. In addition, the economic climate and risk-free rate exhibit a significantly negative coefficient, indicating that positive economic climates as well as a high risk-free rate lead to lower issuance spreads. Thus, the currently prevailing low interest rate in conjunction with moderate economic growth results in increased spreads and therefore hampers bond placements. Enforcement measures by the BMU and BMWi could further exacerbate this unfavorable situation

A loop-mediated isothermal amplification (LAMP) based assay for the rapid and sensitive group-specific detection of fumonisin producing Fusarium spp

Fumonisins are mycotoxins that contaminate maize and maize-based food products, and feed. They have been associated with nerve system disorders in horses, pulmonary edema in swine as well as neural tube defects and esophageal cancer in humans. The fum1 gene codes for a polyketide synthase involved in the biosynthesis of fumonisins. It is present in the genomes of all fumonisin producing Fusarium spp. Reliable detection of fum1 can provide an estimate of the toxicological potential of cultures and food sources. Therefore, a fum1 specific LAMP assay was developed and tested with purified DNA of 48 different species from the Fusarium fujikuroi species complex (FFSC). The fum1 gene was detected in 22 species among which F. fujikuroi, F. globosum, F. nygamai, F. proliferatum, F. subglutinans and F. verticillioides were the most prominent fumonisin producers. None out of 92 tested non-Fusarium species showed cross reactions with the new assay. The lowest limit of detection (LOD) was 5 pg of genomic DNA per reaction for F. fujikuroi, F. nygamai and F. verticillioides. Higher LODs were found for other LAMP positive species. Apart from pure genomic DNA, the LAMP assay detected fumonisin-producers when 103 conidia/reaction were used as template after mechanical lysis. LAMP-results were well correlated with FB1 production. This is the first report on fumonisin production in strains of F. annanatum, F. coicis, F. mundagurra, F. newnesense, F. pininemorale, F. sororula, F. tjataeba, F. udum and F. werrikimbe. Usefulness of the LAMP assay was demonstrated by analyzing fumonisin contaminated maize grains. The new LAMP assay is rapid, sensitive and reliable for the diagnosis of typical fumonisin producers and can be a versatile tool in HACCP concepts that target the reduction of fumonisins in the food and feed chain.Fil: Wigmann, Évelin F..

Development of Small Carbonate Banks on the South Florida Platform Margin: Response to Sea Level and Climate Change

Geophysical and coring data from the Dry Tortugas, Tortugas Bank, and Riley\u27s Hump on the southwest Florida margin reveal the stratigraphic framework and growth history of these carbonate banks. The Holocene reefs of the Dry Tortugas and Tortugas Bank are approximately 14 and 10 m thick, respectively, and are situated upon Pleistocene reefal edifices. Tortugas Bank consists of the oldest Holocene corals in the Florida Keys with earliest coral recruitment occurring at ∼9.6 cal ka. Growth curves for the Tortugas Bank reveal slow growth (less than 1 mm/yr) until 6.2 cal ka, then a rapid increase to 3.4 mm/yr, until shallow reef demise at ∼4.2 cal ka. Coral reef development at the Dry Tortugas began at ∼6.4 cal ka. Aggradation at the Dry Tortugas was linear, and rapid (∼3.7 mm/yr) and kept pace with sea-level change. The increase in aggradation rate of Tortugas Bank at 6.2 cal ka is attributed to the growth of the Dry Tortugas reefs, which formed a barrier to inimical shelf water. Termination of shallow (less than 15 m below sea level) reef growth at Tortugas Bank at ∼4.2 cal ka is attributed to paleoclimate change in the North American interior that increased precipitation and fluvial discharge. Reef growth rates and characteristics are related to the rate of sea-level rise relative to the position of the reef on the shelf margin, and are additionally modified by hydrographic conditions related to climate change
