Magnetite-rich iron oxide copper-gold deposits are geologically and geochemically complex and present major challenges to geophysical investigation. They often sit beneath significant cover, exhibit magnetic remanence, and suffer from self-demagnetization effects. Because remanence in magnetite-bearing drill core samples is commonly overprinted by drilling, in situ natural remanent magnetization is difficult to measure accurately, and thus IOCGs cannot be modeled definitively using geophysics alone. We examined structural controls on a magnetite-rich IOCG in northwest Queensland and the relationships between structure, alteration, Fe (...) oxides, and mineralization at core to deposit scale. Magnetite within the deposit has a multidomain structure, and thus it would commonly have an in situ magnetization parallel to the earth’s field. In contrast, pyrrhotite has a pseudosingle-domain structure and so it is the predominant carrier of stable remanence within the ore system. Geophysical lineament analyses are used to determine structural controls on mineralization, geophysical filters are used to help define structural extent of the deposit, and basement geochemistry is used to map mineral footprints beneath cover. These techniques identified coincident anomalies at the intersection of north and northwest lineaments. Leapfrog™ interpolations of downhole magnetic susceptibility and Cu, Au, and Fe assay data were used to map the distribution of magnetite, copper, gold, and sulfur in 3D. The analysis revealed that Cu and Au mineralization were coupled with the magnetite net-vein architecture, but that Cu was locally enriched in the east–northeast-trending demagnetized zone. The results from this suite of geophysical, petrophysical, and geochemical techniques were integrated to constrain modeling of the Brumby IOCG. Brumby can be described as a breccia pipe sitting at the intersection of north-striking, east-dipping, and northwest-striking, southeast-dipping structures that plunges moderately to the south–southeast. The breccia pipe was overprinted by a relatively late net-vein magnetite breccia and crosscut by a later, magnetite-destructive, east–northeast-striking fault. (shrink)

The results of four experiments provide evidence for controlled processing in the absence of awareness. Participants identified the colour of a neutral distracter word. Each of four words was presented in one of the four colours 75% of the time or 50% of the time . Colour identification was faster when the words appeared in the colour they were most often presented in relative to when they appeared in another colour, even for participants who were subjectively unaware of any contingencies (...) between the words and the colours. An analysis of sequence effects showed that participants who were unaware of the relation between distracter words and colours nonetheless controlled the impact of the word on performance depending on the nature of the previous trial. A block analysis of contingency-unaware participants revealed that contingencies were learned rapidly in the first block of trials. Experiment 3 showed that the contingency effect does not depend on the level of awareness, thus ruling out explicit strategy accounts. Finally, Experiment 4 showed that the contingency effect results from behavioural control and not from semantic association or stimulus familiarity. These results thus provide evidence for implicit control. (shrink)

Educating business students for ethical professional practice is a growing concern for both the corporate world and business education. Highly publicised scandals have pushed public trust in business to an all?time low, resulting in losses of customers and high employee turnover. Corporate and business education leaders have begun to press for more effective models for promoting ethical development in business education. This study examined the effectiveness of one such model, Deliberate Psychological Education (DPE), in promoting greater cognitive moral reasoning in (...) undergraduate business students. Its significant, positive findings hold promise for the promotion of more ethical business professionals through preparatory classroom intervention. (shrink)

Recent studies show that when words are correlated with the colours they are printed in , colour identification is faster when the word is presented in its correlated colour than in an uncorrelated colour . The present series of experiments explored the possible mechanisms involved in this colour-word contingency learning effect. Experiment 1 demonstrated that the effect is already present after 18 learning trials. During subsequent unlearning, the effect extinguished equally rapidly. Two reanalyses of data from Schmidt, Crump, Cheesman, (...) and Besner ruled out an account of the effect in terms of stimulus repetitions. Experiment 2 demonstrated that participants who carry a memory load do not show a contingency effect, supporting the hypothesis that limited-capacity resources are required for learning. Experiment 3 demonstrated that memory resources are required for both storage and retrieval processes. (shrink)

A translation based on the Latin text of the Leonine edition. The Quaestiones Disputatae de Veritate constitutes Aquinas's most extended treatment of any single topic. Volume I discusses the nature of truth and divine and angelic intellects. Volume II deals with truth and human intellect. Volume III investigates the operation of the will.

Using a parallel mixed-methods design, the current study examined university students’ perceptions of academic cheating through collecting and analyzing both the quantitative and qualitative data. Our quantitative findings corroborate previous research that male students have engaged more in academic cheating than females based on students’ self-reports, and that undergraduate students are less willing to discuss issues on academic cheating as compared with their graduate counterparts. Five themes emerged from the thematic analysis of the qualitative data: flexible definitions for cheating, environmental (...) promotion of cheating, the moral transgression of cheating, cheating as an ambiguous justification, and cheating as a conscious decision making process. The mixed-methods findings indicate that there is no relationship between students’ gender or classification and their endorsements of the qualitative themes. However, non-White students are more likely to endorse the theme “cheating as an ambiguous justification.” Implications for reducing and preventing academic cheating at the university level are discussed.

In three experiments, each of a set colour-unrelated distracting words was presented most often in a particular target print colour . In Experiment 1, half of the participants were told the word-colour contingencies in advance and half were not . The instructed group showed a larger learning effect. This instruction effect was fully explained by increases in subjective awareness with instruction. In Experiment 2, contingency instructions were again given, but no contingencies were actually present. Although many participants claimed to be (...) aware of these contingencies, they did not produce an instructed contingency effect. In Experiment 3, half of the participants were given contingency instructions that did not correspond to the correct contingencies. Participants with these false instructions learned the actual contingencies worse than controls. Collectively, our results suggest that conscious contingency knowledge might play a moderating role in the strength of implicit learning. (shrink)

Les sociétés occidentales modernes sont souvent caractérisées comme « plurielles » et « pluralistes ». Cependant, cela n’exclut pas un consensus intégrateur sur les valeurs.Au contraire, le pluralisme fait lui-même partie d’un système de valeurs communément reconnu : l’éthique démocratique, avec son présupposé fondamental d’une dignité inhérente à la personne humaine en tant que telle et de « droits inaliénables » qui en découlent. La dignité humaine est l’équivalent séculier du symbole chrétien de l’« image de Dieu ». Le Christianisme (...) a influencé et continue à influencer le monde occidental, explicitement par la présence des Églises, implicitement par les orientations qu’il a instillées dans l’esprit occidental en matière de valeurs. Ces valeurs sont à ce point admises que leur origine chrétienne est largement oubliée.Qu’ils soient croyants ou non, les femmes et les hommes du monde occidental devraient prendre conscience des éléments chrétiens intégrés dans leur identité culturelle et apprécier leur importance. Modern Western societies are often styled as « plural » and « pluralistic ». Yet they do not lack an integrating value consensus.On the contrary : Pluralism is itself part of a commonly held value system : the democratic ethos with its basic assumption of a dignity inherent in the human person as such and of « inalienable rights » flowing from it. Human dignity is the secular equivalent of the Christian symbol of the « image of God ». Christianity has influenced and keeps influencing the Western world, explicitly by the presence of the churches, implicitly by the value orientations it has instilled into the Western mind. These values are so much taken for granted that their Christian origin is largely forgotten.Whether believers or not, Western men and women should know about and appreciate the Christian elements integrated into their cultural identity.
