Managing User Associations and the Factors of Laws and Cultures in an Information Flow Control Model for Object-Oriented Systems

by Shih-chien Chou
"... Users who play roles in an executing application may be in different security levels. In the application, information in high security levels should not be leaked to users in low security levels. To prevent information leakage, information flow control models can be used. We developed a series of mo ..."

This paper presents the newest model we developed, which of-fers the following two new functions: (1) correcting permissions invalidated by user as-sociation change and (2) adapting to different laws and cultures in different

Refactoring Object-Oriented Frameworks

by William F. Opdyke , 1992
"... This thesis defines a set of program restructuring operations (refactorings) that support the design, evolution and reuse of object-oriented application frameworks. The focus of the thesis is on automating the refactorings in a way that preserves the behavior of a program. The refactorings are defin ..."

A Set Of Principles For Conducting And Evaluating Interpretive Field Studies In Information Systems

by Heinz K. Klein, Michael D. Myers , 1999
"... This article discusses the conduct and evaluation of interpretive research in information systems. While the conventions for evaluating information systems case studies conducted according to the natural science model of social science are now widely accepted, this is not the case for interpretive f ..."

Modern Information Retrieval

by Ricardo Baeza-Yates, Berthier Ribeiro-Neto , 1999
"... Information retrieval (IR) has changed considerably in the last years with the expansion of the Web (World Wide Web) and the advent of modern and inexpensive graphical user interfaces and mass storage devices. As a result, traditional IR textbooks have become quite out-of-date which has led to the i ..."

Separation of ownership and control

by Eugene F. Fama, Michael C. Jensen - JOURNAL OF LAW AND ECONOMICS , 1983
"... This paper analyzes the survival of organizations in which decision agents do not bear a major share of the wealth effects of their decisions. This is what the literature on large corporations calls separation of “ownership” and “control.” Such separation of decision and risk bearing functio ..."

Toward a model of text comprehension and production

by Walter Kintsch, Teun A. Van Dijk - Psychological Review , 1978
"... The semantic structure of texts can be described both at the local microlevel and at a more global macrolevel. A model for text comprehension based on this notion accounts for the formation of a coherent semantic text base in terms of a cyclical process constrained by limitations of working memory. ..."

. Furthermore, the model includes macro-operators, whose purpose is to reduce the information in a text base to its gist, that is, the theoretical macrostructure. These opera-tions are under the control of a schema, which is a theoretical formulation of the comprehender's goals. The macroprocesses

The empirical case for two systems of reasoning

by Steven A. Sloman , 1996
"... Distinctions have been proposed between systems of reasoning for centuries. This article distills properties shared by many of these distinctions and characterizes the resulting systems in light of recent findings and theoretical developments. One system is associative because its computations ref ..."

Risk and protective factors for alcohol and other drug problems in adolescence and early adulthood: Implications for substance abuse prevention

by J. David Hawkins, Richard E Catalano, Janet Y Miller - Psychological Bulletin , 1992
"... The authors suggest that the most promising route to effective strategies for the prevention of adolescent alcohol and other drug problems is through a risk-focused approach. This approach requires the identification of risk factors for drug abuse, identification of methods by which risk factors hav ..."

Culture in action: Symbols and strategies
