    Notes: One of the key features of the new economy seems to be the change from individual to collective efficiency: the joint performance of systems of networked enterprises. That movement has an international dimension mainly related to the new strategies of transnational corporations. from the perspective of developing countries important changes might be taking place, as a consequence of the positioning of their firms in that new interorganisational networking. This is the focus of this study. An analytical model was developed for the assessment of which industrial segment shows the potential to be an international player for having the required organisational competencies. The conceptual framework was built around the idea that participation in an interorganisational network depends on the competencies built by each firm and influences the conditions for strategy formulation. A survey about the recent evolution of industry in Brazil was prepared. The outcomes reveal the relative position of the Brazilian firms in international networks, what leads to an overall picture of the competitiveness of local industry.

    Notes: Abstract. A parallel pipeline is shown to be a natural method of speeding up a typical computer vision application, face inspection using `eigenfaces'. Faces within a stream of video images are continuously surveyed in a manner akin to a `conveyor belt' inspection process. The parallelisation is a new exemplar of a scheme for the rapid prototyping of large-scale, multi-algorithm applications suitable for transfer to a message-passing multicomputer. A general solution, pipelined processor farms, is preferred to a customised solution. This paper gives details of the software tools and software engineering methods employed to tackle this class of problem.

    Notes: Abstract  A long-term study of the effects of nutrient enrichment on coral reefs (ENCORE Experiment) was carried out at One Tree Island (23°30′S; 152°96′E), Great Barrier Reef, between 1992 and 1996. The experiment involved the addition of water-soluble nutrients to 12 microatolls which contained a range of organisms and were situated within the larger lagoon. Three replicates of each of three nutrient treatments (nitrogen, phosphorus, nitrogen plus phosphorus) and an untreated set of three control atolls were prepared using the 12 selected microatolls. As part of the larger ENCORE experiment, changes in the chemical composition of the alcyonacean soft coral Sarcophyton ehrenbergi Marenzeller (Octocorallia: Alcyonacea), placed in the treatment microatolls, were monitored for a 1 yr period in an attempt to detect any responses attributable to nutrient enrichment. Multivariate analyses were performed to determine whether there were any patterns of response in the different nutrient treatments. At the level of individual metabolites, there were no clear treatment effects. However, the ratio of bioactive or stress metabolites (terpenes) to energy storage metabolites (lipids), referred to as the “physiological-change indicator”, revealed effects of nutrient enrichment. Nitrogen enrichment resulted in a trend towards higher physiological-change indicators than control or phosphorus treatments in the majority of cases, while phosphorus enrichment significantly decreased the ratio relative to controls. In most cases, the physiological-change indicator increased in soft soft corals relocated into contact with the scleractinian Pocillopora damicornis. The potential of soft corals to serve as indicators of a changed nutrient regime is discussed.

    Family with neurofibromatosis type 2 and autosomal dominant hearing loss: identification of carriers of the mutated NF2 gene (1995)

    Notes: Abstract A family is presented in which neurofibromatosis type 2 (NF2) and autosomal dominant hearing loss segregate in an apparently independent way. The presence of the latter condition caused anxiety in all family members at risk for NF2 in whom hearing loss became apparent. Previously, we identified a G → A transition in the donor splice site of exon 5 of the NF2 gene in a family member with proven NF2. As expected, the mutation was present in two other family members who fulfilled the diagnostic criteria for NF2. Four out of five family members at risk for NF2 developed hearing loss. Two of these had the G → A transition. The mutation was absent in the two other individuals with hearing loss and in the fifth family member without hearing loss or other clinical symptoms. In this family, the identification of the underlying NF2 gene mutation excluded NF2 as the cause of hearing loss in two potential carriers of the mutated gene. On the other hand, it enabled the identification of two carriers of the NF2 gene mutation who did not fulfill the diagnostic criteria for NF2. They will have to be monitored very carefully for the development of NF2-associated tumors. The consistent association within this family of a relatively mild clinical phenotype with the NF2 mutation, supports earlier suggestions that intrafamilial variability is small in NF2

    Notes: Abstract In this study the GSTμ phenotype and ADH genotype at the ADH3 locus were investigated in a group of 39 alcoholic men with upper respiratory/digestive tract cancer: 21 with oropharyngeal cancer and 18 with laryngeal cancer. The results are compared with those of a control group of 37 alcoholic men without alcohol-related medical complications. Of the control subjects, 48% were found to be GSTμ deficient [GSTμ(–)] and 19% carried the ADH3 1/ADH3 1 genotype. In the laryngeal cancer patients, a significantly elevated frequency of both the GSTμ(–) (78%) and ADH3 1/ADH3 1 genotype (56%) was observed, relative to the control group. On the basis of this result, the risk of laryngeal cancer associated with the GSTμ(–) and ADH3 1/ ADH3 1 genotypic combination within the population of alcoholics was estimated to be 12.9 with a 95% confidence interval of 1.8–92 (P 〈 0.01) relative to alcoholic individuals who have GSTμ [GSTμ(+)] and are not ADH3 1/ADH3 1. Thus, alcoholics who are GSTμ(–) and ADH3 1/ADH3 1 have at least an 80% greater risk of developing laryngeal cancer than alcoholics who are GSTμ(+) and who are not ADH3 1/ ADH3 1. In addition, the oropharyngeal cancer patients had excess frequencies of both GSTμ(–) (62%) and ADH3 1/ ADH3 1 (43%) relative to the control group, but these excess frequencies were not statistically significant. The GSTμ(–) and ADH3 1/ADH3 1 genotypic combination may be a constitutional risk factor for laryngeal cancer among alcoholics.

    Calogero–Moser systems with periodic and doubly periodic interaction potentials and loop algebras (2001)

    Notes: For a finite number of particles on the line pairwise interacting with 1/r2 potential, the positions are given by the eigenvalues of some time-dependent matrix. Infinite periodic or doubly periodic replication of the particles yields Calogero–Moser systems with periodic or doubly periodic interaction potential. We are thus led to consider matrices of infinite order, which are identified with Fourier series with matrix coefficients, depending on an additional parameter. These distributional loops of matrices (tori of matrices in the doubly periodic case) are shown to obey simple (partial) differential equations, which allow us to determine them explicitly. Thus we obtain the already known solution of the Calogero–Moser system on the circle, and provide a new insight for the system on the torus. © 2001 American Institute of Physics.

    The changing pattern of operations management in developing countries: The case of Brazil (1999)

    Notes: Economic activity is becoming increasingly globalised. Multinational enterprises, which are the main drivers of that process, are reconsidering the role of their subsidiaries. In countries where the industrialisation process was heavily dependent on multinationals, such as Brazil, these changes are intrinsically relevant, as they influence the operations of local companies as well as the definition of economic and industrial policies. This paper, based on longitudinal studies of 21 leading Brazilian companies (11 subsidiaries and 10 local), identifies the different roles performed by the subsidiaries in the global competitive strategies chosen by distinct TNCs as well as the strategic and organisational changes adopted by local companies aiming to participate in global productive chains and networks. The final picture reveals that the transition to a globalised competition logically requires the development of new concepts of production systems for developed and developing countries.

    Notes: The haemagglutinin HA is a trimer of identical subunits and is the more abundant viral surface glycoprotein of the influenza virus. It is the target of antibodies that neutralize viral infectivity. Antibodies that bind to HA with 3:1 and 1:1 stoichiometries have been identified. Here, an antibody whose Fab binds to HA with an unprecedented 2:1 Fab:HA stoichiometry is characterized. The complex has been crystallized and synchrotron data to 3.5 Å resolution have been collected. Molecular replacement confirms the stoichiometry of the complex.
