A celebrity chef goes global : the business of eating

Purpose &ndash; This paper examines the internationalization strategy of Gordon Ramsay Holdings Ltd (GRH) from its base in London. While a substantial body of research on the strategic prerequisites for successful internationalization already exists, little attention has been given within this literature to the international growth of small, informally organized and entrepreneurially-driven firms. The discussion also identifies the challenges facing GRH as it strives to continue its international expansion. Design/methodology/approach &ndash; The paper utilizes various published sources from the general press, business press and trade journals to examine the international expansion of GRH on the back of the personal brand the charismatic Gordon Ramsay has achieved in culinary and media circles. The growth of the GRH organization is interpreted through a theoretical framework of strategic capabilities and relationships. Findings &ndash; The analysis illustrates how critical resources and capabilities, branded reputation, and strategic relationships established in GRH\u27s home market have been leveraged effectively overseas. The most fundamental challenge facing GRH going forward is balancing the opportunities and pressures for growth against the need to maintain the highest levels of quality in existing establishments. This &ldquo;balancing act&rdquo; has to unfold within an empire in which the entrepreneur-emperor (Ramsay) has less and less time to devote to any particular activity or establishment. Originality/value &ndash; The case illustrates the importance of developing and leveraging strategic capabilities and relationships in support of successful international expansion. Some of the unique challenges associated with the internationalization of small, informally organized and entrepreneurially-driven (and branded) firms are addressed in terms of both problems and solutions.<br /

Non-market strategy and the \u27race to the bottom\u27: lessons from the Baywatch experience

This article examines how international firms operate strategically in the non-market environment to secure advantages which improve their cost and/or revenue structures and, hence, their economic performance. It centres on a detailed case study of the globally popular Baywatch television show\u27s efforts during 1999 to secure attractive locational subsidies by placing the states of New South Wales, Queensland (both in Australia) and Hawaii into competition with each other in a \u27race to the bottom\u27. The article is organized into three main sections: the first briefly reviews the concept of non-market strategy; the second examines the Baywatch case in detail; and the conclusion presents some lessons for various stakeholders involved in this and similar non-market contexts.<br /

Apprehending business and society

This paper claims to make a contribution by addressing a significant number of epistemological, theoretical and methodological problems in the business and society literature. We identify six sets of potential influences promoting corporate social responsibility. The private sector encompasses intra-organisational obligations and pressures from competitors, investors and consumers. Governmental and non-governmental organisations exert regulatory pressures. Calling upon radical institutional theory, we address each set with respect to its conceptual arguments, its empirical salience in terms of the latest relevant research, and our considered opinion regarding its prospects to be a significant factor in promoting outcomes consistent with social welfare. The conclusion addresses their combined potential to put capitalism on a firmly sustainable track, or whether they amount to an ideological distraction from capitalist pathologies. A call is made for fresh imaginings of the discourse.<br /

Disrobing the emperor : mainstream CSR research and corporate hegemony

Purpose &ndash; This paper aims to utilise a typological matrix as the basis to categorise various corporate-society interventions. It aims to argue that an instrumental version of corporate social responsibility (CSR) is hegemonic in both the theoretical and normative domains of mainstream research, and that this hegemony underpins an intellectual blockage that prevents the field from achieving critical reflexivity and ultimately, a justifiable raison d\u27e^tre. Design/methodology/approach &ndash; The paper reflects on the extant CSR literature in the context of globalisation; presents a two-dimensional typological matrix to be used in positioning corporate-society interventions; provides examples of particular activities relevant to each quadrant of the matrix; and considers the wider political economy of CSR research. Findings &ndash; The logical implications of the corporation as an institution behaving in increasing accordance with the normative expectations of mainstream CSR scholarship will likely lead in the direction of increasing corporate hegemony. Practical implications &ndash; The paper proposes the adoption of the more theoretically coherent and empirically precise terms enlightened self-interest and corporate social irresponsibility in CSR and related research streams, as well as the institutional relocation of much future CSR research to disciplinary areas outside of the business school. Originality/value &ndash; The typological matrix presented in this paper offers a new way of locating corporate-society interventions. The partial abandonment of the term &ldquo;CSR&rdquo; by researchers, as well as the institutional relocations of much CSR research, are original notions.<br /

Degenerate Kalman filter error covariances and their convergence onto the unstable subspace

The characteristics of the model dynamics are critical in the performance of (ensemble) Kalman filters. In particular, as emphasized in the seminal work of Anna Trevisan and coauthors, the error covariance matrix is asymptotically supported by the unstable-neutral subspace only, i.e., it is spanned by the backward Lyapunov vectors with nonnegative exponents. This behavior is at the core of algorithms known as assimilation in the unstable subspace, although a formal proof was still missing. This paper provides the analytical proof of the convergence of the Kalman filter covariance matrix onto the unstable-neutral subspace when the dynamics and the observation operator are linear and when the dynamical model is error free, for any, possibly rank-deficient, initial error covariance matrix. The rate of convergence is provided as well. The derivation is based on an expression that explicitly relates the error covariances at an arbitrary time to the initial ones. It is also shown that if the unstable and neutral directions of the model are sufficiently observed and if the column space of the initial covariance matrix has a nonzero projection onto all of the forward Lyapunov vectors associated with the unstable and neutral directions of the dynamics, the covariance matrix of the Kalman filter collapses onto an asymptotic sequence which is independent of the initial covariances. Numerical results are also shown to illustrate and support the theoretical findings

Comparison of dimethyl sulfoxide treated highly conductive poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) electrodes for use in indium tin oxide-free organic electronic photovoltaic devices

Indium tin oxide (ITO)-free organic photovoltaic (OPV) devices were fabricated using highly conductive poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) as the transparent conductive electrode (TCE). The intrinsic conductivity of the PEDOT:PSS films was improved by two different dimethyl sulfoxide (DMSO) treatments – (i) DMSO was added directly to the PEDOT:PSS solution (PEDOT:PSSADD) and (ii) a pre-formed PEDOT:PSS film was immersed in DMSO (PEDOT:PSSIMM). X-ray photoelectron spectroscopy (XPS) and conductive atomic force microscopy (CAFM) studies showed a large amount of PSS was removed from the PEDOT:PSSIMM electrode surface. OPV devices based on a poly(3-hexylthiophene):[6,6]-phenyl-C61-butyric acid methyl ester (P3HT:PCBM) bulk hetrojunction showed that the PEDOT:PSSIMM electrode out-performed the PEDOT:PSSADD electrode, primarily due to an increase in short circuit current density from 6.62 mA cm−2 to 7.15 mA cm−2. The results highlight the importance of optimising the treatment of PEDOT:PSS electrodes and demonstrate their potential as an alternative TCE for rapid processing and low-cost OPV and other organic electronic devices

Inefficient Cytotoxic T Lymphocyte–Mediated Killing of HIV-1–Infected Cells In Vivo

Understanding the role of cytotoxic T lymphocytes (CTLs) in controlling HIV-1 infection is vital for vaccine design. However, it is difficult to assess the importance of CTLs in natural infection. Different human leukocyte antigen (HLA) class I alleles are associated with different rates of progression to AIDS, indicating that CTLs play a protective role. Yet virus clearance rates following antiretroviral therapy are not impaired in individuals with advanced HIV disease, suggesting that weakening of the CTL response is not the major underlying cause of disease progression and that CTLs do not have an important protective role. Here we reconcile these apparently conflicting studies. We estimate the selection pressure exerted by CTL responses that drive the emergence of immune escape variants, thereby directly quantifying the efficiency of HIV-1–specific CTLs in vivo. We estimate that only 2% of productively infected CD4þ cell death is attributable to CTLs recognising a single epitope. We suggest that CTLs kill a large number of infected cells (about 107) per day but are not responsible for the majority of infected cell death

The Viking viewer for connectomics: scalable multi-user annotation and summarization of large volume data sets

Modern microscope automation permits the collection of vast amounts of continuous anatomical imagery in both two and three dimensions. These large data sets present significant challenges for data storage, access, viewing, annotation and analysis. The cost and overhead of collecting and storing the data can be extremely high. Large data sets quickly exceed an individual's capability for timely analysis and present challenges in efficiently applying transforms, if needed. Finally annotated anatomical data sets can represent a significant investment of resources and should be easily accessible to the scientific community. The Viking application was our solution created to view and annotate a 16.5 TB ultrastructural retinal connectome volume and we demonstrate its utility in reconstructing neural networks for a distinctive retinal amacrine cell class. Viking has several key features. (1) It works over the internet using HTTP and supports many concurrent users limited only by hardware. (2) It supports a multi-user, collaborative annotation strategy. (3) It cleanly demarcates viewing and analysis from data collection and hosting. (4) It is capable of applying transformations in real-time. (5) It has an easily extensible user interface, allowing addition of specialized modules without rewriting the viewer
