In industries like telecom, postal services or energy provision, universal service obligations (uniform price and universal coverage) are often imposed on one market participant. Universal service obligations are likely to alter firms' strategic behavior in such competitive markets. In this paper we show that, depending on the entrant's market coverage and the degree of product differentiation, the Nash equilibrium in prices involves either pure or mixed strategies. We show that the pure strategy market sharing equilibrium, as identified by Valletti et al. (2002) defines a lower bound on the level of equilibrium prices. [less ▲]

Price discrimination is one of the most complex areas of EC competition law. There are several reasons for this. First, the concept of price discrimination covers many different practices (discounts and rebates, tying, selective price cuts, discriminatory input prices set by vertically-integrated operators, etc.) whose objectives and effects on competition significantly differ. From the point of view of competition law analysis, it is thus not easy to classify these practices under a coherent analytical framework. Second, there is a consensus among economists that the welfare effects of the (various categories of) price discrimination are ambiguous. It is hard to say a priori whether a given form of price discrimination increases or decreases welfare. The response to this question may indeed depend on which type of welfare standard (total or consumer) is actually pursued. Moreover, even if one agrees on a given standard, the welfare effects of discriminatory prices generally depend on factual issues, such as whether it increases or decreases total output. Third, the exact scope of Article 82(c), the only Treaty provision dealing with discrimination, is not entirely clear. While the European Commission (hereafter, the Commission) and the Community courts have applied Article 82(c) to many different practices, there are good reasons to believe that this provision should be applied to a limited set of circumstances, most forms of discrimination being adequately covered by Article 82(b) or other provisions of the Treaty. Against this background, the main objective of this paper is to throw some light on the compatibility of price discrimination with EC competition law. In order to do so, this paper does not seek to propose a grand unifying theory that would provide a single test offering a way to distinguish between practices compatible and incompatible with the EC Treaty. Instead, we offer an analytical framework which distinguishes between different categories of price discrimination depending on their effects on competition. Different tests may thus be needed to assess the compatibility of the practices belonging to these categories with EC competition law. Another objective of the paper is to show that Article 82(c) should only be applied to the limited circumstances where a non-vertically integrated dominant firm price discriminates between customers with the effect of placing one or several of them at a competitive disadvantage vis-a-vis other customers (secondary line price discrimination). In contrast, Article 82(c) should not be applied to pricing measures designed to harm the dominant firm's competitors (first line price discrimination) or to fragment the single market across national lines. As will be seen, relying on Article 82(c) to condemn such practices goes against the letter and the spirit of this provision and may also apply a wrong test to such practices. It is also not necessary since other Treaty provisions can be used to achieve this objective. [less ▲]

This paper offers an examination of three significant familial inscriptions from the Hellenistic period. The texts are detailed cultic dossiers initiated by three individuals—Diomedon on Cos, Poseidonios in Halicarnassus, and Epikteta on Thera. Though they are often very briefly grouped together, these inscriptions are discussed here in greater textual and contextual detail. In particular, the analysis focusses on the cult personnel, which is appointed in these families, demonstrating that it remains independent from the polis, but is organised with reference to a civic framework. By setting these inscriptions in parallel, the discussion opens up productive perspectives on the evolutions of familial cults in the Hellenistic period.—The inscription of Poseidonios is reedited in an Appendix by Jan-Mathieu Carbon.

The objective of truss topology optimization is to find, for a given weight, the stiffest truss, defined as a subset of an initially choosen set of bars called the ground structure. The restrictions are bounds on bar volumes and the satisfaction of equilibrium equations. For a single load case and without bounds on bar volumes, the problem can be written as a linear programming problem with nodal displacements as variables. The addition to the objective function of a quadratic term vanishing at the optimum allows us to use a dual solution scheme. A conjugate gradient method is well suited to maximize the dual function. Several ground structures are introduced. For large networks, those where each node is connected to those situated in a certain vicinity give a good compromise between generating a reasonable number of bars and obtaining a sufficient number of possible directions. Some examples taken from the literature are treated to illustrate the quality of the solution and the influence of initial topology. (C) 1997 Civil-Comp Ltd and Elsevier Science Ltd. [less ▲]

AL amyloidosis is a rare systemic disease resulting from tissue accumulation of amyloid fibrils derived from monoclonal immunoglobulin light chains. It can disrupt the tissue architecture and consequently cause organ dysfunction. The prognosis is poor with a median survival of 13 months in untreated patients. By illustrating the case of a patient whose AL amyloidosis was detected after presenting a nephrotic syndrome, the characteristics of the disease are reviewed as well as diagnostic criteria and current available therapeutics.

As derived from gene cloning and sequencing, the 489-amino-acid DD-peptidase/penicillin-binding protein (PBP) produced by Actinomadura R39 has a primary structure very similar to that of the Escherichia coli PBP4 [Mottl, Terpstra & Keck (1991) FEMS Microbiol. Lett. 78, 213-220]. Hydrophobic-cluster analysis of the two proteins shows that, providing that a large 174-amino-acid stretch is excluded from the analysis, the bulk of the two polypeptide chains possesses homologues of the active-site motifs and secondary structures found in the class A β-lactamase of Streptomyces albus G of known three-dimensional structure. The 74-amino-acid insert occurs at equivalent places in the two PBPs, between helices α2 and α3, away from the active site. Such an insert is unique among the penicilloyl serine transferases. It is proposed that the Actinomadura R39 PBP and E. coli PBP4 form a special class, class C, of low-Mr PBPs/DD-peptidases. A vector has been constructed and introduced by electrotransformation in the original Actinomadura R39 strain, allowing high-level expression and secretion of the DD-peptidase/PBP (250 mg . 1-1). The gene encoding the desired protein is processed differently in Actinomadura R39 and Streptomyces lividans. Incorrect processing in Streptomyces lividans leads to a secreted protein which is inert in terms of DD-peptidase activity and penicillin-binding capacity. [less ▲]

We retrospectively analyzed 32 cases of primary central nervous system lymphoma (PCNSL). Five cases were diagnosed in the period 1987-1994, for 27 cases in the period 1995-2002. There were 17 men and 15 women whose median age was 69 years. Three patients were immunodeficient. The commonest symptoms were focal deficit (16 patients) and cognitive/behaviour disturbances (14 patients). Radiologically, a total of 47 contrast-enhancing lesions were observed in 32 patients; 18 patients had deep-seated lesions. All but two patients underwent histological diagnosis following craniotomy (11 patients) and/or stereotaxic biopsy (22 patients); diagnosis was obtained on CSF cytology in one patient with a third ventricle tumour. In the last patient, the diagnosis was based on the finding of marked tumour shrinkage under corticotherapy, despite two negative histological examinations. Treatment included surgical resection (10 patients), chemotherapy (25 patients) and/or radiotherapy (12 patients). According to the therapeutic recommendations of the GELA (Groupe d'Etude des Lymphomes de l'Adulte), 19 patients received at least two courses of high-dose methotrexate; intrathecal chemotherapy was used in 20 patients with methotrexate and/or cytosine arabinoside. Radiation therapy consisted of whole brain irradiation followed by a boost on tumour site. Nine patients received a combined treatment of chemotherapy and radiotherapy. Twelve patients showed rapid progression to death. At the time of last contact, 28/32 patients (88%) had died, all from PCNSL disease or from complications due to its treatment. The median Survival time was 13.9 months. We conclude that PCNSL is an increasingly frequent tumour. The diagnosis is obtained by stereotactic biopsy in the majority of cases. The prognosis appears dismal despite an intensive multidisciplinary therapeutic approach. (C) 2004 Elsevier B.V. All rights reserved. [less ▲]

Primary cerebral lymphoma is a rare disease. The aim of this study is to compare the survival of the patients treated with radiotherapy alone vs. patients treated with a combined schedule of radio-chemotherapy. Our results will be compared with currently published data and main prognostic factors will be briefly discussed. PATIENTS AND METHODS: Between 1974 and 1990, 27 cases of primary cerebral lymphoma were diagnosed at our institution. All patients had biopsy-proven disease, the pathology of which was reviewed for this study. RESULTS: The overall median survival time was 24 months and one-, two- and three-year overall survival was 59, 46 and 29% respectively. The median radiation dose was 46 Gy, ranging from 19.5 to 60 Gy. The median dose per fraction was 2 Gy (ranging from 1.61 to 3 Gy). The median elapsed treatment time was 32 days (ranging from three to 45 days). We were not able to demonstrate any statistically significant difference between patients who received radiotherapy alone (n = 14, median survival time = 24 months) and those who received a combination of chemotherapy and radiotherapy (n = 11, median survival time = 30 months), (p = 0.4). Prognostic factors of survival were tested using a univariate analysis (Wilcoxon test). Parameters such as mass appearance (unilobular, p = 0.048), performance status at the time of the diagnosis (0 to 1, p = 0.014), and CT imaging (hypodense, p = 0.043) influenced positively survival. Centroblastic histology (Kiel) was found associated with a negative prognosis (p = 0.043). CONCLUSION: In our experience, there is no statistically significant difference of survival between patients treated with radiotherapy alone or with a combined treatment of radio-chemotherapy. Other prognostic factors of survival were discovered, although the analysis was univariate, due to the limited number of patients. Multicentric prospective studies should be elaborated in order to optimize the treatment of this disease. [less ▲]
