Multinational Enterprises in the New Europe: Are They Really Global?

Despite a pervasive belief that the world’s largest firms compete globally, the vast majority have most of their sales in their home region. Of the top 500 firms for which regional sales data are available, 118 are from Europe, and they compete predominantly within the European region. On average, 62.8% of their sales are in their home region; only three are global, 8 are host-region oriented and 16 are bi-regional, while 86 are home-region based. To illustrate the four categories, we present case studies of 9 European multinationals — Carrefour, TotalFinaElf, Deutsche Bank, Nokia, Philips, GlaxoSmithKline, L’Oréal Paris, Diageo,and AstraZeneca. We analyze the geographical distribution of their operations and their current structure. We also show that management research is strongly focusedon the special cases of global and bi-regional firms, rather than on the large majority of home-region firms. This implies that managing in the new Europe needs tobe regional, not global.

The Regional Focus of Asian Multinational Enterprises

In recent issues of this journal a debate has raged concerning the appropriate nature of academic research in the Asia Pacific region. In keeping with the expressed desire for both rigor and regional relevance in this research, we wish to demonstrate a strong commonality between the performance of large Asian firms and others from Europe and North America. The large Asian firms mostly operate on an intra-regional basis. It has been assumed that the path to success for Asian firms is globalization, yet we show that the literature supporting this is confined to a handful of unrepresentative case studies.Asian multinationals, regional strategy, internationalization, bibliometric analysis, firm-specific advantages

The Regional Nature of the World’s Automotive Sector

There are 29 automotive firms in the world’s largest 500 firms. Yet none of these are “global” firms, defined as having at least 20 per cent of their sales in each of the three regions of the broad “triad” of the E.U., North America and Asia. Indeed 23 of the 29 auto and auto parts firms are home-region based, with an average of 60.6 per cent of their sales as intra-regional. These are representative firms across the 500, as the average intra-regional sales for all manufacturing firms is 61.8 per cent. These are a few special cases, especially Toyota and Nissan of firms being active in two regions of the triad. DaimlerChrysler and Honda are “host-region oriented”. Seven cases are discussed in some detail to explore the reasons for the lack of globalization in the world automotive business.regional, intra-regional, automotive, globalization

Application of enhanced thermal ratings to primary substation transformers

The use of thermal modelling to increase the permissible load-carrying capability of distribution system transformers is attracting increasing interest. Many reported approaches calculate the rating of transformers in real-time in response to system conditions. In this paper, we describe an experiment to validate and tune the parameters of such a thermal model, and explain how the results have been used to inform the inclusion of model-based seasonal “enhanced” ratings in the network planning process

Network planning case study utilising real-time thermal ratings and computational fluid dynamics

Real-Time Thermal Ratings (RTTR) has a natural synergy with wind generation, since during periods of high local wind speed increased wind farm output coincides with uplifted line ratings. This paper describes a network planning study on a real section of UK distribution network. The study considers a branch of 132kV network connecting several wind farms to the grid. By assessing the local wind conditions in the area surrounding the wind farm and proposed overhead line, the study predicts the increase in energy throughput, and hence accommodated generation, for different routes considered for the overhead line. The locations of thermal bottlenecks in the proposed routes are identified. The study shows that a wind farm of 140MW can be connected to a conductor which could only support 90MW based on its static rating, and if the route is chosen correctly only 1% of the energy yield will be constrained

Fast frequency response from energy storage systems - A review of grid standards, projects and technical issues

Electric power systems foresee challenges in stability due to the high penetration of power electronics interfaced renewable energy sources. The value of energy storage systems (ESS) to provide fast frequency response has been more and more recognized. Although the development of energy storage technologies has made ESSs technically feasible to be integrated in larger scale with required performance, the policies, grid codes and economic issues are still presenting barriers for wider application and investment. Recent years, a few regions and countries have designed new services to meet the upcoming grid challenges. A number of grid-scale ESS projects are also implemented aiming to trial performance, demonstrate values, and gain experience. This paper makes a review on the above mentioned aspects, including the emerging frequency regulation services, updated grid codes and grid-scale ESS projects. Some key technical issues are also discussed and prospects are outlined

Killing Tensors and Conformal Killing Tensors from Conformal Killing Vectors

Koutras has proposed some methods to construct reducible proper conformal Killing tensors and Killing tensors (which are, in general, irreducible) when a pair of orthogonal conformal Killing vectors exist in a given space. We give the completely general result demonstrating that this severe restriction of orthogonality is unnecessary. In addition we correct and extend some results concerning Killing tensors constructed from a single conformal Killing vector. A number of examples demonstrate how it is possible to construct a much larger class of reducible proper conformal Killing tensors and Killing tensors than permitted by the Koutras algorithms. In particular, by showing that all conformal Killing tensors are reducible in conformally flat spaces, we have a method of constructing all conformal Killing tensors (including all the Killing tensors which will in general be irreducible) of conformally flat spaces using their conformal Killing vectors.Comment: 18 pages References added.

Mitosis can drive cell cannibalism through entosis.

Entosis is a form of epithelial cell cannibalism that is prevalent in human cancer, typically triggered by loss of matrix adhesion. Here, we report an alternative mechanism for entosis in human epithelial cells, driven by mitosis. Mitotic entosis is regulated by Cdc42, which controls mitotic morphology. Cdc42 depletion enhances mitotic deadhesion and rounding, and these biophysical changes, which depend on RhoA activation and are phenocopied by Rap1 inhibition, permit subsequent entosis. Mitotic entosis occurs constitutively in some human cancer cell lines and mitotic index correlates with cell cannibalism in primary human breast tumours. Adherent, wild-type cells can act efficiently as entotic hosts, suggesting that normal epithelia may engulf and kill aberrantly dividing neighbours. Finally, we report that Paclitaxel/taxol promotes mitotic rounding and subsequent entosis, revealing an unconventional activity of this drug. Together, our data uncover an intriguing link between cell division and cannibalism, of significance to both cancer and chemotherapy
