    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.

    PKA and Sch9 control a molecular switch important for the proper adaptation to nutrient availability (2005)

    Notes: In the yeast Saccharomyces cerevisiae, PKA and Sch9 exert similar physiological roles in response to nutrient availability. However, their functional redundancy complicates to distinguish properly the target genes for both kinases. In this article, we analysed different phenotypic read-outs. The data unequivocally showed that both kinases act through separate signalling cascades. In addition, genome-wide expression analysis under conditions and with strains in which either PKA and/or Sch9 signalling was specifically affected, demonstrated that both kinases synergistically or oppositely regulate given gene targets. Unlike PKA, which negatively regulates stress-responsive element (STRE)- and post-diauxic shift (PDS)-driven gene expression, Sch9 appears to exert additional positive control on the Rim15-effector Gis1 to regulate PDS-driven gene expression. The data presented are consistent with a cyclic AMP (cAMP)-gating phenomenon recognized in higher eukaryotes consisting of a main gatekeeper, the protein kinase PKA, switching on or off the activities and signals transmitted through primary pathways such as, in case of yeast, the Sch9-controlled signalling route. This mechanism allows fine-tuning various nutritional responses in yeast cells, allowing them to adapt metabolism and growth appropriately.

    Effect of petrochemical sludge concentrations on microbial communities during soil bioremediation (2005)
    Oxford, UK : Blackwell Publishing Ltd
    FEMS microbiology ecology 53 (2005), S. 0 
    Details

    Topics: Biology
    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.

    Description / Table of Contents: Contributions to the Chemistry of Sulfur. 115. Crystal and Molecular Structure of BenzopentathiepineThe structure of benzopentathiepine has been determined from three-dimensional single-crystal X-ray data. The crystal are monoclinic, space group P21/c, with 4 molecules in the unit cell of dimensions a = 6.942(4) Å, b = 10.223(10) Å, c = 13.015(8) Å, β = 102,15(10)°. The conformation of the seven-membered ring is the chair form. Details of the conformation are discussed. Bond distances, bond angles, and dihedral angles are compared with those in other molecules, which have similar structure.
