Purpose – The focus of extant strategy literature is on for-profit organisations and within these group public organisations. There are other forms of organisations and following the deep recession of 2008 there is greater interest in other forms of organisation. In this case study and interview the aim is to examine strategy, strategic decisions and strategic management of a not-for-profit provident. Design/methodology/approach – The paper draws on documentary evidence and a semi-structured interview with Ray King, chief executive of Bupa. The perspective of CEO is key in strategy and such perspectives are relatively rarer. Findings – Bupa invests its surplus to provide better healthcare. Free from the pressures of quarterly reporting and shareholders it can pursue long-term value creation for members rather than short-term surpluses. Research limitations/implications – The case study and interview offers a unique insight into strategy-making within a successful mutual provident that has grown organically and externally becoming an international leader in health insurance. Originality/value – This case study sheds light on strategy-making within a not-for-profit provident that has diversified and grown significantly over the past six decades. Furthermore, very few case studies offer insight into the thinking of a chief executive who has successfully managed a business in a turbulent environment.

Purpose – The purpose of this paper is to demonstrate how strategy is developed and implemented in an organisation with an unusual ownership model. Partnerships are not a prevalent form of ownership but as this case demonstrates they can be extremely effective. Furthermore this case demonstrates how logical incrementalism can be used to implement major strategic decisions. Design/methodology/approach – The paper draws on company documentary evidence and a semi-structured interview with Mr Charlie Mayfield, Chairman of John Lewis Partnership. A chairman has a helicopter view of business whose perspectives are rarely captured by strategy researchers. This case study offers an insight into strategic thinking of a chairman and chief executive of a successful company. Research limitations/implications – The case study and interview offer a unique insight into the rationale behind strategic decisions within a successful partnership that has grown organically in a highly competitive retail market without high gearing. Originality/value – This case study sheds light on strategic moves within partnership. Furthermore, very few case studies offer insight into the thinking of a chief executive who has successfully managed a business in a turbulent environment.

Synoptic activity over the Northern Hemisphere is evaluated in ensembles of ECHAM5/MPI-OM1 simulations for recent climate conditions (20C) and for three climate scenarios (following SRES A1B, A2, B1). A close agreement is found between the simulations for present day climate and the respective results from reanalysis. Significant changes in the winter mid-tropospheric storm tracks are detected in all three scenario simulations. Ensemble mean climate signals are rather similar, with particularly large activity increases downstream of the Atlantic storm track over Western Europe. The magnitude of this signal is largely dependent on the imposed change in forcing. However, differences between individual ensemble members may be large. With respect to the surface cyclones, the scenario runs produce a reduction in cyclonic track density over the mid-latitudes, even in the areas with increasing mid-tropospheric activity. The largest decrease in track densities occurs at subtropical latitudes, e.g., over the Mediterranean Basin. An increase of cyclone intensities is detected for limited areas (e.g., near Great Britain and Aleutian Isles) for the A1B and A2 experiments. The changes in synoptic activity are associated with alterations of the Northern Hemisphere circulation and background conditions (blocking frequencies, jet stream). The North Atlantic Oscillation index also shows increased values with enhanced forcing. With respect to the effects of changing synoptic activity, the regional change in cyclone intensities is accompanied by alterations of the extreme surface winds, with increasing values over Great Britain, North and Baltic Seas, as well as the areas with vanishing sea ice, and decreases over much of the subtropics.

We present a dynamic causal model that can explain context-dependent changes in neural responses, in the rat barrel cortex, to an electrical whisker stimulation at different frequencies. Neural responses were measured in terms of local field potentials. These were converted into current source density (CSD) data, and the time series of the CSD sink was extracted to provide a time series response train. The model structure consists of three layers (approximating the responses from the brain stem to the thalamus and then the barrel cortex), and the latter two layers contain nonlinearly coupled modules of linear second-order dynamic systems. The interaction of these modules forms a nonlinear regulatory system that determines the temporal structure of the neural response amplitude for the thalamic and cortical layers. The model is based on the measured population dynamics of neurons rather than the dynamics of a single neuron and was evaluated against CSD data from experiments with varying stimulation frequency (1–40 Hz), random pulse trains, and awake and anesthetized animals. The model parameters obtained by optimization for different physiological conditions (anesthetized or awake) were significantly different. Following Friston, Mechelli, Turner, and Price (2000), this work is part of a formal mathematical system currently being developed (Zheng et al., 2005) that links stimulation to the blood oxygen level dependent (BOLD) functional magnetic resonance imaging (fMRI) signal through neural activity and hemodynamic variables. The importance of the model described here is that it can be used to invert the hemodynamic measurements of changes in blood flow to estimate the underlying neural activity.

We examine whether and under what circumstances World Bank and International Monetary Fund (IMF) programs affect the likelihood of major government crises. We find that crises are, on average, more likely as a consequence of World Bank programs. We also find that governments face an increasing risk of entering a crisis when they remain under an IMF or World Bank arrangement once the economy's performance improves. The international financial institution's (IFI) scapegoat function thus seems to lose its value when the need for financial support is less urgent. While the probability of a crisis increases when a government turns to the IFIs, programs inherited by preceding governments do not affect the probability of a crisis. This is in line with two interpretations. First, the conclusion of IFI programs can signal the government's incompetence, and second, governments that inherit programs might be less likely to implement program conditions agreed to by their predecessors.

The protease activated receptor-2 (PAR-2) belongs to a family of G-protein-coupled receptors that are activated by proteolysis. Trypsin cleaves PAR-2, exposing an N-terminal tethered ligand (SLIGRL) that activates the receptor. Messenger RNA (mRNA) for PAR-2 was found in guinea pig airway tissue by reverse transcription-polymerase chain reaction, and PAR-2 was found by immunohistochemistry in airway epithelial and smooth-muscle cells. In anesthetized guinea pigs, trypsin and SLIGRL-NH(2) (given intratracheally or intravenously) caused a bronchoconstriction that was inhibited by the combination of tachykinin-NK(1) and -NK(2) receptor antagonists and was potentiated by inhibition of nitric oxide synthase (NOS). Trypsin and SLIGRL-NH(2) relaxed isolated trachea and main bronchi, and contracted intrapulmonary bronchi. Relaxation of main bronchi was abolished or reversed to contraction by removal of epithelium, administration of indomethacin, and NOS inhibition. PAR-1, PAR-3, and PAR-4 were not involved in the bronchomotor action of either trypsin or SLIGRL-NH(2), because ligands of these receptors were inactive either in vitro or in vivo, and because thrombin (a PAR-1 and PAR-3 agonist) did not show cross-desensitization with PAR-2 agonists in vivo. Thus, we have localized PAR-2 to the guinea-pig airways, and have shown that activation of PAR-2 causes multiple motor effects in these airways, including in vivo bronchoconstriction, which is in part mediated by a neural mechanism.

Alkyl esters of p–hydroxybenzoic acid (parabens) are widely used as preservatives in personal care products, foods and pharmaceuticals. Their oestrogenic activity, their measurement in human breast tissue and their ability to drive proliferation of oestrogen-responsive human breast cancer cells has opened a debate on their potential to influence breast cancer development. Since proliferation is not the only hallmark of cancer cells, we have investigated the effects of exposure to parabens at concentrations of maximal proliferative response on migratory and invasive properties using three oestrogen-responsive human breast cancer cell lines (MCF-7, T-47-D, ZR-75-1). Cells were maintained short-term (1 week) or long-term (20±2 weeks) in phenol-red-free medium containing 5% charcoal-stripped serum with no addition, 10-8M 17-oestradiol, 1-5x10-4M methylparaben, 10-5M n-propylparaben or 10-5M n-butylparaben. Long-term exposure (20±2 weeks) of MCF-7 cells to methylparaben, n-propylparaben or n-butylparaben increased migration as measured using a scratch assay, time-lapse microscopy and xCELLigence technology: invasive properties were found to increase in matrix degradation assays and migration through matrigel on xCELLigence. Western immunoblotting showed an associated downregulation of E-cadherin and -catenin in the long-term paraben-exposed cells which could be consistent with a mechanism involving epithelial to mesenchymal transition. Increased migratory activity was demonstrated also in long-term paraben-exposed T-47-D and ZR-75-1 cells using a scratch assay and time-lapse microscopy. This is the first report that in vitro, parabens can influence not only proliferation but also migratory and invasive properties of human breast cancer cells.

This article reports the results of a mixed-methods approach to investigating the association between globalisation and MATESOL in UK universities. Qualitative and quantitative data collected from academic staff through eight emails, four interviews and 41 questionnaires indicate that the globalised context of higher education have affected these programmes in a number of ways including an increasing interest in recruiting more international students and a growing awareness about the need for curriculum and content modifications. The analysis of the data suggests that although change has been an inherent characteristic of these MAs over the past decade, it has been implemented gradually and conservatively, often relying on a dialectic relationship between academic staff and universities’ policies. The results imply that factors other than globalisation have also been at work. Many of the participants contend that globalisation has not lowered the quality of these MAs or standards of good practice.

Multi-proxy analyses from floodplain deposits in the Colne Valley, southern England, have provided a palaeoenvironmental context for the immediately adjacent Terminal Upper Palaeolithic and Early Mesolithic site of Three Ways Wharf. These deposits show the transition from an open cool environment to fully developed heterogeneous floodplain vegetation during the Early Mesolithic. Several distinct phases of burning are shown to have occurred that are chronologically contemporary with the local archaeological record. The floodplain itself is shown to have supported a number of rare Urwaldrelikt insect species implying human manipulation of the floodplain at this time must have been limited or episodic. By the Late Mesolithic a reed-sedge swamp had developed across much of the floodplain, within which repeated burning of the in situ vegetation took place. This indicates deliberate land management practices utilising fire, comparable with findings from other floodplain sequences in southern Britain. With similar sedimentary sequences known to exist across the Colne Valley, often closely associated with contemporary archaeology, the potential for placing the archaeological record within a spatially explicit palaeoenvironmental context is great.

Purpose – The purpose of this paper is to demonstrate how strategy is developed and implemented within a subsidiary of a global organization, the relationship between subsidiary and headquarters and the need for continuous change and adaption to remain relevant. Furthermore, this case study describes a successful process of invention and adoption. Design/methodology/approach – The paper draws on documentary evidence and a semistructured interview with Jill McDonald CEO and President of McDonald’s Northern Europe Division with responsibility for the UK, Sweden, Finland, Denmark, Norway and the Republic of Ireland. Management research rarely captures the views of the top executive, yet the top executives have a broad picture and are key strategic decision makers. Findings – The case study and interview offers a unique insight into factors contributing to McDonald’s unprecedented success (it has paid an increased dividend for the past 37 years). It also sheds light on its successful internationalization strategy. Originality/value – The case study draws on published material and augments this with an in-depth interview with the Chief Executive. Very few case studies offer insight into the thinking of a Chief Executive managing a subsidiary of a global organization. Its value lies in the lessons that managers and students of management can draw on the approach adopted by a highly successful global organization.
