    Title: Petrology and Geochemistry of Ultramafic-Gabbroic Intrusions in the Abitibi Area, Ontario, Author: Neil D. MacRae, Location: ThodeA brief review of the general geology of the peridotite belt south of Lake Abitibi is presented. The petrography and geochemistry of each major intrusion is discussed in detail and mineral and element variation diagrams are drawn for a number of cross sections. The degree of differentiation of the initial magmas is discussed and illustrated by comparison with a hypothetical model. On the assumption that all ultramafic-gabbroic intrusions in the area are related, a model for the physical evolution of the assemblage is suggested. The criteria of classification of ultramafic rocks are examined with particular reference to the analysed rocks. In this relationship, a brief statement of the origin of basaltic magmas is presented.ThesisDoctor of Philosophy (PhD

    Mine and me: exploring the neural basis of object ownership.

    Previous research has shown that encoding information in the context of self-evaluation leads to memory enhancement, supported by activation in ventromedial pFC. Recent evidence suggests that similar self-memory advantages can be obtained under nonevaluative encoding conditions, such as when object ownership is used to evoke self-reference. Using fMRI, the current study explored the neural correlates of object ownership. During scanning, participants sorted everyday objects into self-owned or other-owned categories. Replicating previous research, a signifi- cant self-memory advantage for the objects was observed (i.e., self-owned &amp;gt; other-owned). In addition, encoding self-owned items was associated with unique activation in posterior dorso- medial pFC (dMPFC), left insula, and bilateral supramarginal gyri (SMG). Subsequent analysis showed that activation in a subset of these regions (dMPFC and left SMG) correlated with the magni- tude of the self-memory advantage. Analysis of the time-to-peak data suggested a temporal model for processing ownership in which initial activation of dMPFC spreads to SMG and insula. These results indicate that a self-memory advantage can be elic- ited by object ownership and that this effect is underpinned by activity in a neural network that supports attentional, reward, and motor processing

    Objective To measure the effect of brief behavioural counselling in general practice on patients’ consumption of fruit and vegetables in adults from a low income population. Design Parallel group randomised controlled trial. Setting Primary health centre in a deprived, ethnically mixed inner city area. Participants 271 patients aged 18-70 years without serious illness. Intervention Brief individual behavioural counselling based on the stage of change model; time matched nutrition education counselling. Main outcome measures Self reported number of portions of fruit and vegetables eaten per day, plasma β carotene, α tocopherol, and ascorbic acid concentrations, and 24 hour urinary potassium excretion. Assessment at baseline, eight weeks, and 12 months. Results Consumption of fruit and vegetables increased from baseline to 12 months by 1.5 and 0.9 portions per day in the behavioural and nutrition groups (mean difference 0.6 portions, 95% confidence interval 0.1 to 1.1). The proportion of participants eating five or more portions a day increased by 42% and 27% in the two groups (mean difference 15%, 3% to 28%). Plasma β carotene and α tocopherol concentrations increased in both groups, but the rise in β carotene was greater in the behavioural group (mean difference 0.16 μmol/l, 0.001 μmol/l to 1.34 μmol/l). There were no changes in plasma ascorbic acid concentrations or urinary potassium excretion. Differences were maintained when analysis was restricted to the 177 participants with incomes ≤ £400 (€596, $640) a week. Conclusions Brief individual counselling in primary care can elicit sustained increases in consumption of fruit and vegetables in low income adults in the general population

    Help, I need somebody: Automatic action and inaction

    The goal of behavioral control is of central importance in everyday life. When the production of an unwanted action can have deleterious consequences for perceivers, there is considerable virtue in the possession of a mental system that edits its behavioral products to meet the demands of a challenging world. Accordingly, in an attempt to extend existing work on this topic (e.g., Bargh, Chen, &amp; Burrows, 1996), in the present research we investigated the extent to which the automatic elicitation of action may be moderated by features of the task environment and perceivers' goal states. Our findings were unequivocal. When inhibitory cues were present in the environment (i.e., Experiment 1), or perceivers had a competing goal in mind (i.e., Experiment 2), automatic behavioral priming effects were eliminated. We consider the implications of our findings for recent treatments of behavioral priming and action control.</p
