  • Parallel corpora are made by human beings. However, as an MT system is an aggregation of state-of-the-art NLP technologies without any intervention of human beings, it is unavoidable that quite a few sentence pairs are beyond its analysis and that will therefore not contribute to the system. Furthermore, they in turn may act against our objectives to make the overall performance worse. Possible unfavorable items are n : m mapping objects, such as paraphrases, non-literal translations, and multiword expressions.

  • Whereas the selection of segmentation variables mainly drawn from management needs is straightforward, the selection of variables used as descriptors of the identified segments is more complex. This complexity stems not only from the enormous num- ber of possible variables, but also from the necessary twofold link these variables have to offer, namely the link with the selected segmentation variables on the one hand, and the link with secondary data on media profiles, distributional coverage etc.

  • The run on prime MMMFs caused further disruption to already stressed short term corporate credit markets. Though many of the redemptions from prime MMMFs flowed into Treasury and Government MMMFs, and thus MMMF assets in aggregate fell less sharply than those of prime MMMFs, the Treasury and Government funds were not eligible to purchase many of the corporate issues that prime MMMFs were selling or ceasing to roll over.

  • We use these theoretical underpinning to specify estimable equations for the supply of and demand for corporate credit. Since theory does not provide clues as to the possible structural forms of these equations we basically rely on reduced forms. Data considerations, in particular, the availability of relevant statistical data, also has played a certain role in the specification of these equations.

  • Skylines, and other directly related problems such as multiobjective opti- mization [Steuer 1986], maximum vectors [Kung et al. 1975; Matousek 1991], and the contour problem [McLain 1974], have been extensively studied and nu- merous algorithms have been proposed formain-memory processing. To the best of our knowledge, however, the first work addressing skylines in the context of databaseswasBorzsonyi et al.

  • Graphical techniques reveal that there is a strong correlation between turnover rates and the firm’s decision not to offer health insurance, and this pattern holds both in the aggregate (Figure 4) and when firm size is controlled for (Figure 5). In each figure, the average turnover rate is measured on the horizontal axis and the proportion of firms not offering health insurance is measured on the vertical axis.

Alert details include transmission data such as, source and destination IP addresses in the packet, as well as security analysis information (performed by the Sensor) such as attack type and severity. Alerts are backed up to the database and archived in order of occurrence.

  • Our aim is to contribute to the above literature by proposing a life-cycle model with individual income uncertainty that can be used to assess how various macroeconomic factors a®ect the equilibrium value of household credit. We show that its value de- pends on (i) the lending-deposit interest rate spread, (ii) individual income uncertainty, (iii) individual productivity persistence, and (iv) the generosity of the pension system.

  • While there is a broad literature on the returns to schooling, few studies have investigated the returns to an MBA. The value of an MBA degree is a concern to potential MBA students, and articles in the popular press and schools themselves often report average starting salaries of graduates as an indicator of program effectiveness without addressing issues of selection. The more rigorous attempts to determine the efficiency or value-added of MBA programs rely on aggregate data of student characteristics as reported by top-rated schools (Tracy and Waldfogel, 1997; Colbert et al.
