    Informal contacts and performance in innovation teams (2005)

    Notes: Purpose - The paper addresses the effect friendly and friendship relationships among members of innovation teams on the performance of the teams. Design/methodology/approach - The members of innovation teams may develop friendly and friendship relationships over time. In our study, we focus on the effect of the frequency of such non-work relationships on team performance. For this research, we collected full network data on non-work relationships in a sample of 44 innovation teams and investigate how these "friendly and friendship networks" affect the performance of innovation teams. Findings - As result turns out that the frequency of friendly ties has positive as well as negative consequences on team performance, whereas the frequency of friendship ties positively relates to the performance. Research limitations/implications - The results indicate the importance of informal relations for the performance of innovation teams. Further, it is shown that friendly and friendship relations have different theoretical and practical implications. Future research can overcome the limitations of the presented research by concentrating on larger sample sizes and longitudinal research designs. Practical implications - Building on the results of the study managers can better orchestra innovation teams focussing not only on formal but also on informal contacts. The main practical implication is to strive for friendship contacts and to avoid too strong friendly contacts. Originality/value - The study adds knowledge to the research on informal relationships and performance two-fold. First, the findings testify that friendly and friendship contacts are different and not part of the same dimension, and there is strong evidence for the importance of informal contacts.

    Effect of petrochemical sludge concentrations on microbial communities during soil bioremediation (2005)

    Notes: Qualitative and quantitative changes of microbial communities in soil microcosms during bioremediation were determined throughout one year. The soil was contaminated with 0%, 2.5%, 5%, 10% (wt/wt) of petrochemical sludge containing polynuclear aromatic hydrocarbons. We analyzed the hydrocarbon concentration in the microcosms, the number of cultivable bacteria using CFU and most probable number assays, the community structure using denaturing gradient gel electrophoresis, and the metabolic activity of soil using dehydrogenase activity and substrate-induced respiration assays. After one year of treatment, the chemical analysis suggested that the hydrocarbon elimination process was over. The biological analysis, however, showed that the contaminated microcosms suffered under long-term disturbance. The number of heterotrophic bacteria that increased after sludge addition (up to 108–109 cells ml−1) has not returned to the level of the control soil (2–6 × 107 cells ml−1). The community structure in the contaminated soils differed considerably from that in the control. The substrate-induced respiration of the contaminated soils was significantly lower (10-fold) and the dehydrogenase activity was significantly higher (20–40-fold) compared to the control. Changes in the community structure of soils depended on the amount of added sludge. The species, which were predominant in the sludge community, could not be detected in the contaminated soils.

    In-Situ CO2 Monitoring Network Evaluation and Design: A Criterion Based on Atmospheric CO2 Variability (2013)
    Wiley
    Details
    Publication Date: 2013-01-17
    Description: [1]  Estimates of surface fluxes of carbon dioxide (CO 2 ) can be derived from atmospheric CO 2 concentration measurements through the solution of an inverse problem, but the sparseness of the existing CO 2 monitoring network is often cited as a main limiting factor in constraining fluxes. Existing methods for assessing or designing monitoring networks either primarily rely on expert knowledge, or are sensitive to the large number of modeling choices and assumptions inherent to the solution of inverse problems. This study proposes a monitoring network evaluation and design approach based on the quantification of the spatial variability in modeled atmospheric CO 2 . The approach is used to evaluate the 2004-2008 North American network expansion, and to create two hypothetical further expansions. The less stringent expansion guarantees a monitoring tower within one correlation length of each location (1 CL), requiring an additional 8 towers relative to 2008. The more stringent network includes a tower within one half of a correlation length (½ CL) and requires 35 towers beyond the 1 CL network. The two proposed networks are evaluated against the network in 2008, which temporarily had the most continuous monitoring sites in North America thanks to the Mid-Continent Intensive project. Evaluation using a synthetic data inversion shows a marked improvement in the ability to constrain both continental- and biome-scale fluxes, especially in areas that are currently under-sampled. The proposed approach is flexible, computationally inexpensive, and provides a quantitative design tool that can be used in concert with existing tools to inform atmospheric monitoring needs.

    The use of variable CO2 in the data assimilation of AIRS and IASI radiances (2012)
    Wiley
    Details
    Publication Date: 2012-04-15
    Description: An important component of the assimilation of radiance observations from the AIRS and IASI satellite instruments is the radiative transfer modelling. Currently, the RTTOV model used in the ECMWF IFS system uses a fixed value for CO 2 . Neglecting the spatio-temporal variability of CO 2 introduces an error in the simulation of the satellite radiances, which could affect the quality of the analyses and forecasts. The current assumption is that variational bias correction corrects most of this error and therefore minimizes the impact on the forecast scores. This paper investigates the possibility of modelling CO 2 within the IFS to improve the radiative transfer modelling. Results show that the required bias correction is significantly reduced when using more realistic CO 2 values. The impact on the analysis quality and forecast scores is mostly neutral with some indication of improvement in the Tropics and the stratosphere. Copyright © 2011 Royal Meteorological Society
