Making academic freedom and institutional autonomy real in boundary conditions: some issues from African higher education
"In this presentation on the occasion of the 20th Anniversary of the Magna Charta Universitatum in Bologna, I will make six points. Some of these are general observations on the Magna Charta and others are issues from African higher education which may help to illuminate our understanding of the value, limits and potential of the Magna Charta.
Rule groupings: An approach towards verification of expert systems
Knowledge-based expert systems are playing an increasingly important role in NASA space and aircraft systems. However, many of NASA's software applications are life- or mission-critical and knowledge-based systems do not lend themselves to the traditional verification and validation techniques for highly reliable software. Rule-based systems lack the control abstractions found in procedural languages. Hence, it is difficult to verify or maintain such systems. Our goal is to automatically structure a rule-based system into a set of rule-groups having a well-defined interface to other rule-groups. Once a rule base is decomposed into such 'firewalled' units, studying the interactions between rules would become more tractable. Verification-aid tools can then be developed to test the behavior of each such rule-group. Furthermore, the interactions between rule-groups can be studied in a manner similar to integration testing. Such efforts will go a long way towards increasing our confidence in the expert-system software. Our research efforts address the feasibility of automating the identification of rule groups, in order to decompose the rule base into a number of meaningful units
Terrorists Are Always Muslim but Never White: At the Intersection of Critical Race Theory and Propaganda
When you hear the word âterrorist,â who do you picture? Chances are, it is not a white person. In the United States, two common though false narratives about terrorists who attack America abound. We see them on television, in the movies, on the news, and, currently, in the Trump administration. The first is that âterrorists are always (brown) Muslims.â The second is that âwhite people are never terrorists.â Different strands of critical race theory can help us understand these two narratives. One strand examines the role of unconscious cognitive biases in the production of stereotypes, such as the stereotype of the âMuslim terrorist.â Another strand focuses on white privilege, such as the privilege of avoiding the terrorist label. These false narratives play a crucial role in Trumpâs propaganda. As the critical race analysis uncovers, these two narratives dovetail with two constituent parts of propaganda: flawed ideologies and aspirational myths. Propaganda relies on preexisting false ideologies, which is another way to describe racist stereotyping. Propaganda also relies on certain ideals and myths, in this case, the myth of white innocence and white superiority. Thus, the Trump administrationâs intentional invocation of both narratives amounts to propaganda in more than just the colloquial sense. Part I illustrates each of the two narratives. Part II then analyzes them through a critical race lens, showing how they map onto two strands of critical race theory. Next, Part III examines how these narratives simultaneously enable and constitute propaganda. Finally, Part IV argues that the propagation of these false narratives hurts the nationâs security
Hospital and home teachers' views about teaching students who have medically defined mental health needs
Rising numbers of students with medically defined mental health needs are
being referred to some hospital and home teaching services (HHTS). In July
2006 hospital and home teachers were surveyed about how this affects their
work, in order to share ideas and help to promote good practice.
A definition of mental health needs was not included in order to avoid limiting
responses. In this challenging area, with no easy answers and this report, a
small contribution to complex discussions, is intended to raise as well as to
answer questions. âStudentsâ will refer to students with medically defined
mental health needs
Multi-viewpoint clustering analysis
In this paper, we address the feasibility of partitioning rule-based systems into a number of meaningful units to enhance the comprehensibility, maintainability and reliability of expert systems software. Preliminary results have shown that no single structuring principle or abstraction hierarchy is sufficient to understand complex knowledge bases. We therefore propose the Multi View Point - Clustering Analysis (MVP-CA) methodology to provide multiple views of the same expert system. We present the results of using this approach to partition a deployed knowledge-based system that navigates the Space Shuttle's entry. We also discuss the impact of this approach on verification and validation of knowledge-based systems
