A comment on the confinement problem

by Steven B. Lipner - In Proceedings of the fifth ACM symposium on Operating systems principles, SOSP ’75 , 1975
"... The confinement problem, as identified by Lampson, is the problem of assuring that a borrowed program does not steal for its author information that it processes for a borrower. An approach to proving that an operating system enforces confinement, by preventing borrowed programs from writing informa ..."

A Note on the Confinement Problem

by Butler W. Lampson , 1973
"... This not explores the problem of confining a program during its execution so that it cannot transmit information to any other program except its caller. A set of examples attempts to stake out the boundaries of the problem. Necessary conditions for a solution are stated and informally justified. ..."

Heuristic Evaluation of User Interfaces

by Jukob Nielsen, Rolf Molich - IN: PROCEEDINGS OF THE CHI´90 CONFERENCE, SEATTLE , 1990
"... Heuristic evaluation is an informal method of usability analysis where a number of evaluators are presented with an interface design and asked to comment on it. Four ex-periments showed that individual evaluators were mostly quite bad at doing such heuristic evaluations and that they only found betw ..."

A closed-form solution for options with stochastic volatility with applications to bond and currency options

by Steven L. Heston - Review of Financial Studies , 1993
"... I use a new technique to derive a closed-form solution for the price of a European call option on an asset with stochastic volatility. The model allows arbitrary correlation between volatility and spotasset returns. I introduce stochastic interest rates and show how to apply the model to bond option ..."

to other problems. Many plaudits have been aptly used to describe Black and Scholes ’ (1973) contribution to option pricing theory. Despite subsequent development of option theory, the original Black-Scholes formula for a European call option remains the most successful and widely used application

Certification of Programs for Secure Information Flow

by Dorothy E. Denning, Peter J. Denning , 1977
"... This paper presents a certification mechanism for verifying the secure flow of information through a program. Because it exploits the properties of a lattice structure among security classes, the procedure is sufficiently simple that it can easily be included in the analysis phase of most existing c ..."

compilers. Appropriate semantics are presented and proved correct. An important application is the confinement problem: The mechanism can prove that a program cannot cause supposedly nonconfidential results to depend on confidential input data.

"... 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 ..."

approach the problem using a forward-looking measure. In particular, we employ changes in the slope of the "smirk" of implied volatilities of options on S&P 500 futures to determine perceived changes in the probability of such jumps. Options and futures prices were obtained from Bridge. Our

Toward a Conceptual Framework for Mixed-Method Evaluation Designs. Educational Evaluation and Policy Analysis

by Jennifer C. Greene, Valerie J. Caracelli, Wendy F. Graham , 1989
"... In recent years evaluators of educational and social programs have expanded their method-ological repertoire with designs that include the use of both qualitative and quantitative methods. Such practice, however, needs to be grounded in a theory that can meaningfully guide the design and implementat ..."

-toire (Cook, 1985; Mathison, 1988). In re-cent years, this repertoire has been consid-erably expanded with the acceptance of qualitative methods as appropriate, legiti-mate, and even preferred for a wide range of evaluation settings and problems. Concom-itantly, evaluators have expressed renewed interest

Abstract: Africa has had slow growth and a massive exodus of capital. In many respects it has been the most capital-hostile region. We

Telephone call centers: Tutorial, review, and research prospects

by Noah Gans, Ger Koole, Avishai Mandelbaum - Mgmt , 2003
"... Telephone call centers are an integral part of many businesses, and their economic role is significant and growing. They are also fascinating socio-technical systems in which the behavior of customers and employees is closely intertwined with physical performance measures. In these environments trad ..."
