title: Random Relational Rules

authors: Pfahringer, Bernhard

subjects: computer science

abstract: Exhaustive search in relational learning is generally infeasible, therefore some form of heuristic search is usually employed, such as in FOIL[1]. On the other hand, so-called stochastic discrimination provides a framework for combining arbitrary numbers of weak classifiers (in this case randomly generated relational rules) in a way where accuracy improves with additional rules, even after maximal accuracy on the training data has been reached. [2] The weak classifiers must have a slightly higher probability of covering instances of their target class than of other classes. As the rules are also independent and identically distributed, the Central Limit theorem applies and as the number of weak classifiers/rules grows, coverages for different classes resemble well-separated normal distributions. Stochastic discrimination is closely related to other ensemble methods like Bagging, Boosting, or Random forests, all of which have been tried in relational learning [3, 4, 5].

title: The soil geochemistry in the Beardmore Glacier Region, Antarctica: Implications for terrestrial ecosystem history

authors: Lyons, W.B.

abstract: Although most models suggest continental Antarctica was covered by ice during the Last Glacial Maximum (LGM) it has been speculated that endemic species of soil invertebrates could have survived the Pleistocene at high elevation habitats protruding above the ice sheets. We analyzed a series of soil samples from different elevations at three locations along the Beardmore Glacier in the Transantarctic Mountains (in order of increasing elevation): Ebony Ridge (ER), Cloudmaker (CM), and Meyer Desert (MD). Geochemical analyses show the MD soils, which were exposed during the LGM, were the least weathered compared to lower elevations, and also had the highest total dissolved solids (TDS). MD soils are dominated by nitrate salts (NO₃/Cl ratios >10) that can be observed in SEM images. High δ¹⁷O and δ¹⁸O values of the nitrate indicate that its source is solely of atmospheric origin. It is suggested that nitrate concentrations in the soil may be utilized to determine a relative “wetting age” to better assess invertebrate habitat suitability. The highest elevation sites at MD have been exposed and accumulating salts for the longest times, and because of the salt accumulations, they were not suitable as invertebrate refugia during the LGM.

title: Archetypes and the unthought: The projection of the King’s Court in New Zealand television media

authors: Mataira, Kelvin

abstract: This thesis explores archetypal projections of conflict in Television New Zealand’s news and current affairs as an unthought. The television news and current affairs programmes identified in the thesis relate to issues of conflict between the Maori people of New Zealand, and the Government and Crown agencies of New Zealand. The unresolved issues of conflict are manifest in what has become popularly known as the Treaty of Waitangi settlement process.

The thesis is informed by Foucault’s conviction that the unthought is the power that is linked to every mode of knowledge. The thesis argues that knowledge in relation to thought is limited because the knowledge is surrounded by an immense region of shadow. In an ontology based on thought only it is shown how the Shadow and the King’s Court archetypes conceal and prevent human beings from comprehending other discourses.

It is argued that Foucault’s concern with the unthought is reflected in Carl Gustav Jung’s convictions about the collective unconscious. Jung’s theory of the quarternio: thinking, sensing, intuition and feeling that describe the four functions of the mind, inform the theory and the methodology for the thesis. It is proposed that the discursive activities of television media can be understood in relation to Hermes the Greek God of magic, lies and illusion. It is further proposed that the images that are projected from television media can be informed by mythical accounts of Hermes’ behaviour and activity in relation to Zeus, Apollo, Dionysus, and Ares.

In the thesis, the quarternio and the Greek Gods are represented by the archetypes of the King’s Court. The Ruler archetype represents Zeus and Apollo as the thinking function of the mind. The Sage archetype is shown to be located in close proximity to the Ruler. The Warrior archetype represents Dionysus as the sensing function of the mind. The Magician archetype represents Hermes as the intuitive function of the mind. The Fool archetype represents Ares as the feeling function of the mind. The Destroyer archetype as the inferior and rejected contents of the collective unconscious represents the archetypal Shadow that undermines the activities of the King’s Court. 

It is maintained in the thesis that television media projections of the King’s Court are a metaphor of the mind, and in particular of the contents of the collective unconscious. The King’s Court as a mythical and archetypal metaphor invites an inspection of the unthought through the epistemology of image. The thesis furnishes a methodology based on the epistemology of television. Through an analysis of popular contemporary films such as the Star Wars Trilogy that are shown to be heavily invested with archetypal motif, discourses for each of the King’s Court archetypes are presented. Foucault’s notion of the rituals and gestures that constitute the true discourse in a regime of truth informs the definition of discourse in the thesis. Discourse in the thesis is to be understood as verbal and non-verbal modes of communication.

Foucault’s notion of disciplinary power provides a method for analysing television news and current affairs programmes as an order of discourse. Disciplinary power enables an understanding of the power relations in television media as the power that circulates in an inquisition between the examiner and the confessor. The archetypes of the King’s Court are projected through the rituals of inquisition in television media.

In the analysis all of the archetypes of the King’s Court are seen except for the Magician. Television it is argued represents the Magician. The Destroyer, the Ruler the Sage, the Warrior and the Fool on television media are controlled by the Magician. The Magician shows that the Ruler’s discourse reflected through the King’s Court represents the regime of truth. The competing discourse of the Destroyer as archetypal foe is located outside of the King’s Court and in opposition to the Ruler’s discourse. The Ruler’s discourse is Apollonine. The Ruler projects the image of control, peace, reconciliation, rationality, serenity, authority, and wealth. The Sage as the intellectual and the Fool as the archetypal Trickster are shown to actively facilitate the power of the Ruler. The Warrior who is projected as a powerful leader may be alienated from the King’s Court.
