The Determinants of Credit Spread Changes.
- Journal of Finance
, 2001
"... ABSTRACT Using dealer's quotes and transactions prices on straight industrial bonds, we investigate the determinants of credit spread changes. Variables that should in theory determine credit spread changes have rather limited explanatory power. Further, the residuals from this regression are ..."

-grade bond yield changes on Treasury yield changes and stock returns (see Kwan (1996)) we find that the R 2 falls to five percent when the dependent variable is credit spread changes. Hence, while much is known about yield changes, we have very limited knowledge about the determinants of credit spread
Cross-domain collaboration recommendation
- In KDD’12
, 2012
"... Interdisciplinary collaborations have generated huge impact to society. However, it is often hard for researchers to establish such cross-domain collaborations. What are the patterns of cross-domain collaborations? How do those collaborations form? Can we predict this type of collaborations? Cross-d ..."

collaborations exhibit very different patterns compared to traditional collaborations in the same domain: 1) sparse connection: cross-domain collaborations are rare; 2) complementary expertise: cross-domain collaborators often have different expertise and interest; 3) topic skewness: cross-domain collaboration
Computational testing : Why, how and how much
- ORSA Journal on Computing
, 1990
"... This considers the issues associated with performing and reporting computational testing in the context of original research in operations research, particularly in its interface with computer science. The scope includes nonnumerical computations, such as fundamental algorithms and information stru ..."

Section 2 suggests broad methods of testing, recognizing strengths and weaknesses of each. Finally, Section 3 gives guidelines for how much computational testing is appropriate, depending on why
Whom You Know Matters: Venture Capital Networks and Investment Performance,

"... Abstract Many financial markets are characterized by strong relationships and networks, rather than arm's-length, spot-market transactions. We examine the performance consequences of this organizational choice in the context of relationships established when VCs syndicate portfolio company inv ..."

Once we control for network effects in our models of fund and portfolio company performance, the importance of how much investment experience a VC has is reduced, and in some specifications, eliminated. Finally, we provide initial evidence on the evolution of VC networks. Key words: Venture

Sharing Expertise: Challenges for Technical Support
- eds): Expertise Sharing: Beyond Knowledge Management, MIT-Press
, 2003
"... Knowledge is an important resource in economy these days. It is typically distributed among different actors and embodied in various artefacts (cf. Saloman 1993; Hutchins 1995; Ackerman and Halverson 1998). So, on the level of national economies as well as on the level of an individual organizations ..."

organizations, it is important to find innovative ways to stimulate learning by sharing knowledge among humans. There are mainly two - often intertwined - ways on how to share knowledge. On the direct way, human actors of different kinds of expertise can communicate and help each other to construct new
Anonymous Hierarchical Identity-Based Encryption (Without Random Oracles). In: Dwork
- CRYPTO 2006. LNCS,
, 2006
"... Abstract We present an identity-based cryptosystem that features fully anonymous ciphertexts and hierarchical key delegation. We give a proof of security in the standard model, based on the mild Decision Linear complexity assumption in bilinear groups. The system is efficient and practical, with sm ..."

, there have been a number of IBE schemes proven secure without random oracles, such as BTE from where r is chosen by the encryptor and g, g 1 , g 3 , and e(g 1 ,ĝ 2 ) are public system parameters. Notice, there are now two elements in G, and between them there is enough redundancy to determine whether a
