of the factors traditionally mentioned as influencing the term structure are thus included in a way which is fully consistent with maximizing behavior and rational expectations. The model leads to specific formulas for bond prices which are well suited for empirical testing.

. Thus, we examine how changes in credit spreads respond to proxies for both changes in the probability of future default and for changes in the recovery rate. Separately, recent empirical studies find that the corporate bond market tends to have relatively high transactions costs and low volume. 1

strand of birds is deficient in thymine, thymine to cytosine transitions are less common than in other taxa. Amino acid replacement in a segment of the cytochrome b gene is faster in mammals and birds than in fishes and the pattern of replacements fits the structural hypothesis for cytochrome b

, and (iii) a heuristic network search based on false discovery rate multiple testing. Steps (ii) and (iii) correspond to an empirical Bayes estimate of the network topology. Results: Using computer simulations we investigate the sensitivity (power) and specificity (true negative rate) of the proposed

This paper details an empirical pilot study that explores the development of several conceptual measures and models regarding intellectual capital and its impact on business performance. The objective of this pilot study is to explore the development of items and constructs through principal

subclass of such systems, we propose using Event-B to helpful their specification and their safe development. In this article, we mainly report our experience with the Even-B stepwise development of a situated MAS which study the displacement of vehicles in a convoy. This article aims also at serving as a

is critical to the interpretation and generation of discourse, the question of how speakers and hearers accomplish this disambiguation is rarely addressed. This paper reports results of empirical studies on discourse and sentential uses of cue phrases, in which both text-based and prosodic features were

of resources, tagging systems are still not well studied or understood. In this paper, we provide a short description of the academic related work to date. We offer a model of tagging systems, specifically in the context of web-based systems, to help us illustrate the possible benefits of these tools. Since

Much recent research has pointed to the critical role of architecture in the development of a firm’s products, services and technical capabilities. A common theme in these studies is the notion that specific characteristics of a product’s design – for example, the degree of modularity it exhibits

the representations have been evoked, their content can influence the behavior during some time. Neurons in a number of brain structures show sustained activations after an initial CS has occurred. The activations arise usually during specific epochs of well-differentiated instrumental tasks, such as during movement
