Suppose a forecasting scheme associates a probability p with some observed outcome. The entropy score given to this forecast is then log p . This article provides a review of the background to this scoring method, its main properties, and its relationships to concepts such as likelihood, probability gain, and Molchan’s m-s diagram. It is shown that, in terms of this score, an intrinsic characte...

We identify characteristics that affect firms’ ability to learn from their export activities. Our analysis employs propensity score matching (PSM) techniques and GMM regressions on a panel of Argentinian firms spanning 1992-2001. Characteristics we find important to learning-by-exporting are: foreign ownership, intensive use of imported inputs, a skilled workforce and small firm size. Finally, ...

Age/gender may likely influence the course of septic complications after trauma. We aimed to characterize the influence of age/gender on the response of circulating cytokines, cells and organ function in post-traumatic sepsis. We additionally tested whether post-traumatic responses alone can accurately predict outcomes in subsequent post-traumatic sepsis. A mouse 2-hit model of trauma/hemorrhag...

introduction: the aim of this study was to evaluate the impact of measurement of coronary artery calcification score (cac) in patients with suspected coronary artery disease (cad) and a normal myocardial perfusion scan. methods: in a prospective study we measured the calcium score of 74 patients (29 m, 45 f, mean age 58.7 (m) and 64.4 (f)) with suspicion of cad and a normal perfusion scan. in ...

In a recent paper we have shown that most non-expansive Lipschitz functions (in the sense of Baire’s category) have a maximal Clarke subdifferential. In the present paper, we show that in a separable Banach space the set of non-expansive Lipschitz functions with a maximal Clarke subdifferential is not only of generic, but also staunch. 1991 Mathematics Subject Classification: Primary 49J52.
