title: Progger 3: A low-overhead, tamper-proof provenance system

authors: Corrick, Tristan James Carlile

subjects: Progger

abstract: Data provenance, which describes how data is accessed and used since the time it is created, is a valuable resource with a wide range of uses. It can be used simply to know who has accessed one's data, or be used in more complex scenarios such as detecting malware. One method for collecting data provenance is to observe system calls. This thesis presents Progger 3, a system that observes system calls on Linux in order to collect data provenance. There are several existing provenance systems that observe system calls, but they have limitations regarding security, efficiency, and usability. Progger 3 remedies many of these limitations. As a result, Progger 3 is a working implementation of a provenance system that can observe any system call, guarantee tamper-proof provenance collection as long as the kernel on the client is not compromised, and transfer the provenance to other systems with confidentiality and integrity, all with a relatively low performance overhead.

title: Culture and Cognitive Theory: Toward a Reformulation

authors: Thakker, Jo

subjects: culture

abstract: In a provocative and important recent article Anthony Marsella (1998) makes an eloquent plea for the forging of a new metadiscipline of psychology that he labels global-community psychology. Marsella argues that we need a radical rethinking of the fundamental premises of psychology, rooted as they are in Western cultural traditions. Features of an emergent global-community psychology include an emphasis on multicultural and multidisciplinary approaches to human behavior that draw attention to the importance of context and meaning in human lives. Marsella's call for a global-community psychology reflects, in part, a growing body of literature that demonstrates the importance of cultural factors in a diver-sity of psychological domains such as cognition, emotion, social behavior, and psychopathology.

title: Bicultural challenges for educational professionals in Aotearoa

authors: Glynn, Ted

abstract: As educational professionals in New Zealand at the approach of the twenty-first century, some 158 years after the Treaty of Waitangi, we face some major challenges in examining our bicultural goals and achievements. In this paper I explore some of these goals and achievements which I believe must be addressed in our pedagogical practice and in our educational research.
