    This research examines human resource management (HRM) in subsidiaries of US multinational firms (MNCs) operating in the UK and Germany. Together with parallel studies in Ireland and Spain it explores the potential tensions resulting from a transfer of US-type human resource (HR) policies to Europe. Whilst we expected that the liberal market British economy would not provide a major challenge for the transfer of US practices, we foresaw that the more densely institutionalized German business system would constitute a more serious barrier to transfer. This report is based on case studies of four large US MNCs. In all four firms we conducted interviews in the British and German subsidiaries, as well as the US and/or European headquarters, with HR managers, line managers and non-managerial employees. For three substantive issues – diversity management, employee participation and pay – as well as for the processual issue of ‘centralization–decentralization’ this report analyses whether the four US MNCs studied have global policies, how these are transferred to Europe and the extent to which they have to be adapted to the British and German contexts. Our findings support previous research which suggests that HR policies in US MNCs are not only relatively standardised, but also build on US domestic policies. However, the mechanisms of transfer appear to have changed. Whereas in the past, written guidelines, the transfer of home-country employees and extensive reporting seem to have been the major mechanisms employed to ensure that global policies were applied, today HR information systems, regional European headquarters and international teams of HR managers seem to play a more important role. Over the last decade, national subsidiaries in both countries have lost autonomy in HR decision-making. However, this has not been primarily in the form of recentralization towards headquarters, but rather towards the regional level and/or business unit. Turning to substantive issues, as expected, the German institutional environment represents a stronger challenge for US MNCs than the British one. Of particular importance is codetermination which affects all four firms and which in at least three of them exerts pressure on local management to adjust global polices to local conditions. However, in most cases the observed deviations were only marginal. Similarly, the German system of multi-employer bargaining does not constitute a major hurdle for US MNCs seeking to apply global practices. Although in general German host-country pressures were stronger than those in the UK, we found that UK management was able to use its role of interpreter of the local environment to force some adaptation of global policies, particularly in the substantive area of diversity management, suggesting that the extent to which local adaptation occurs is not entirely dependent on the strength of employment-relations institutions in the host country. Regarding practical implications, our research points firmly to the limits of global policies. With their knowledge of the local context subsidiary-level managers can and should have some freedom to adapt global policies to the local context. At least in Germany they have an additional role, as they have to manage a complex institutional environment. The system of collective bargaining and codetermination fosters collective HR policies that are often incompatible with the more individualistic global policies pursued by US MNCs. Nevertheless, as the case studies show, US MNCs are able to manage these institutions in such a way that the need for adaptation is minimized. This process of institutional arbitrage tends to be performed by local managers with a deep knowledge of the hostenvironment

    Immobilisation of glycosidases from commercial preparation on magnetic beads: Part 2: Aroma enhancement in wine using immobilised glycosidases

    Most of the terpenes in wines are conjugated to various sugars, representing a significant reservoir of aromatic precursors. To promote the release of these terpenes, certain enzymes, such as ÎČ-glucosidase, α-arabinosidase and α-rhamnosidase, are necessary. A simple and cost-effective procedure for the immobilisation of multiple glycosidase activities (ÎČ-D-glucopyranosidase, α-L-arabinofuranosidase, α-L-rhamnopyranosidase and ÎČ-D-xylopyranosidase) from commercial Aspergillus niger preparation onto magnetic beads as carriers was developed as reported in Part 1 (Ferner et al. 2016).The aim of this work was to analyse a possible application of this immobilised biocatalyst due to its well-known advantages over soluble enzyme preparations – that is, control of the reaction process and preparation of enzyme-free products. Volatile compounds were analysed by gas chromatography (mass spectrometric detection). After the treatment of the model wine with different glycosides and white wine with immobilised glycosidases, the amount of free terpenes was significantly increased with respect to that of the control wine.The results of this study are of considerable interest for possible future applications of immobilised enzymes in the wine-making industry

    Cyanoketene: the microwave spectrum and structure of an unstable molecule

    Get PDF
    Abstract The unstable molecule cyanoketene has been prepared by pyrolysis in a flow system, and the microwave spectra of five isotopic species, a-and b-type, have been measured in the frequency range from 8 to 40 GHz. Precise rotational constants and centrifugal distortion parameters up to the sixth order were obtained. The molecule has been shown to be planar, and a reliable structure was derived. Also the N -quadrupole coupling constants and the dipole moment components have been determined. The results could be a basis for interstellar spectroscopy of this molecule

    Malignant peripheral nerve sheath tumor of the breast: case report

    Get PDF
    <p>Abstract</p> <p>Background</p> <p>Malignant peripheral nerve sheath tumor is a rare soft tissue sarcoma of ectomesenchymal origin. It is the malignant counterpart of benign soft tissue tumors like neurofibromas and schwannomas and may often follow them. Common sites include deeper soft tissues, usually in the proximity of a nerve trunk. Breast is an extremely rare location of this lesion and presentation as a breast lump in the absence of pain or previous benign neural tumor is even rarer.</p> <p>Case presentation</p> <p>A 38-year-old female presented with complaints of painless, hard breast lump for three months which was clinically suspected to be a ductal carcinoma with inconclusive fine needle aspiration cytology. Histopathology revealed a malignant spindle cell tumor which was confirmed to be malignant peripheral nerve sheath tumor on the basis of immunopositivity for vimentin, neurone specific enolase and S-100.</p> <p>Conclusion</p> <p>To the best of our knowledge only six such case reports have been published in literature. The differential diagnosis of malignant peripheral nerve sheath tumor should be considered by the clinician as well as the pathologists in the work-up of a breast neoplasm as treatment and prognosis of this rare malignancy is different.</p

    Contested resources: unions, employers, and the adoption of new work practices in US and UK telecommunications

    Get PDF
    The pattern of adoption of high-performance work practices has been explained in terms of strategic contingency and in terms of union presence. We compare the post-deregulation/privatization changes in work practice at AT&T, Bell Atlantic and British Telecom. On the basis of these cases, we argue that the choice of new work practices should be understood as a consequence not only of the company's resources or changes in its environment, nor of a simple union presence, but also as a consequence of the practices' effects on union power, the nature of the union's engagement, and the union's strategic choices

    Multi‐Site Conformational Exchange in the Synthetic Neomycin‐Sensing Riboswitch Studied by 19 F NMR

    Get PDF
    The synthetic neomycin-sensing riboswitch interacts with its cognate ligand neomycin as well as with the related antibiotics ribostamycin and paromomycin. Binding of these aminoglycosides induces a very similar ground state structure in the RNA, however, only neomycin can efficiently repress translation initiation. The molecular origin of these differences has been traced back to differences in the dynamics of the ligand:riboswitch complexes. Here, we combine five complementary fluorine based NMR methods to accurately quantify seconds to microseconds dynamics in the three riboswitch complexes. Our data reveal complex exchange processes with up to four structurally different states. We interpret our findings in a model that shows an interplay between different chemical groups in the antibiotics and specific bases in the riboswitch. More generally, our data underscore the potential of 19F NMR methods to characterize complex exchange processes with multiple excited states

    ÂčâčF NMR Untersuchung des Konformationsaustauschs mehrerer ZustĂ€nde im synthetischen Neomycin‐bindenden Riboschalter

    Get PDF
    Der synthetische Neomycin-bindende Riboschalter interagiert mit seinem Liganden Neomycin sowie mit den verwandten Antibiotika Ribostamycin und Paromomycin. Die Bindung dieser Aminoglykoside induziert sehr Ă€hnliche Grundzustandsstrukturen in der RNA, allerdings kann nur Neomycin die Initiierung der Translation effizient unterdrĂŒcken. Der molekulare Ursprung dieser Unterschiede wurde auf Unterschiede in der Dynamik der Ligand-Riboschalter-Komplexe zurĂŒckgefĂŒhrt. In diesem Artikel kombinieren wir fĂŒnf komplementĂ€re fluorbasierte NMR-Methoden, um die Dynamik der drei Riboschalter-Komplexe im Sekunden- bis Mikrosekundenbereich genau zu quantifizieren. Unsere Daten offenbaren komplexe Austauschprozesse mit bis zu vier strukturell unterschiedlichen ZustĂ€nden. Wir interpretieren unsere Ergebnisse in einem Modell, das ein Zusammenspiel zwischen verschiedenen chemischen Gruppen in den Antibiotika und spezifischen Basen im Riboschalter zeigt. Allgemeiner unterstreichen unsere Daten das Potenzial von 19F NMR-Methoden, komplexe Austauschprozesse mit mehreren angeregten ZustĂ€nden zu charakterisieren

    Parents’ experiences of caring for a young person with neurofibromatosis type 1 (NF1): a qualitative study

    Get PDF
    Neurofibromatosis type 1 (NF1) is a variable and unpredictable genetic condition that can lead to changes to an individual’s appearance. Research has started to explore children’s and young people’s experiences of living with the condition; however, there is a lack of research with parents. This exploratory qualitative study set out to examine parents’ experiences of caring for a young person with NF1. Seven parents took part in semi structured interviews which were subjected to a thematic analysis. Three key themes were identified which related to managing the uncertainty of the condition, the impact of an altered appearance, and others’ awareness and understanding of NF1. Parents felt that understanding NF1 themselves in order to support their child was beneficial whilst a perceived lack of understanding by others was cited as a significant challenge. Parents require trustworthy information and also more widely call for greater understanding and awareness of the condition
