    A Case of Senator Lynn Beyak and Anti-Indigenous Systemic Racism in Canada

    On March 7, 2017, Canadian Senator Lynn Beyak stood up in the Red Chamber and delivered a lengthy speech urging Canadians to recognise the positive aspects of the Indian Residential Schooling system that the Truth and Reconciliation Commission had failed to acknowledge. In their positions as settler teacher educators, the authors examine how Senator Beyak’s statements expose the depth of systemic settler colonialism, anti-Indigenous racisms, and unsettling beneficiary narratives here in Canada. The authors call on teacher educators to examine these systemic anti-Indigenous racisms in relation to how they can confront and disrupt settler Canadian colonialism and historical settler consciousness within teacher education and school curricula. Drawing on recent research done by educational researchers at Faculties of Education across Canada, the authors maintain that settler colonial benevolence and colonial systemic anti-Indigenous racisms can be unlearned and learned through ethical relationality, truth, and a critical praxis of reconciliation.Le 7 mars 2017, la sénatrice canadienne Lynn Beyak s’est levée dans la Chambre rouge et a prononcé un long discours dans lequel elle incitait les Canadiens à reconnaître les aspects positifs du système des pensionnats indiens que la Commission de vérité et réconciliation n’avait pas reconnus. Comme enseignants et enseignantes descendants des colons, les auteurs de cette communication examinent comment les déclarations de la sénatrice Beyak mettent en évidence la profondeur du colonialisme de peuplement systémique, des racismes anti-autochtones et des récits troublants des conquérants du Canada. Les auteurs demandent aux enseignants et aux éducateurs d’examiner ces racismes systémiques anti-autochtones en relation avec la façon dont ils peuvent confronter et déconstruire le colonialisme de peuplement et la conscience historique des colons dans les programmes scolaires et de formation des enseignants. En s’appuyant sur des recherches récentes effectuées par des chercheurs des Facultés d’éducation du Canada, les auteurs soutiennent que la bienveillance des colons et les racismes coloniaux systémiques anti-autochtones peuvent non seulement être déconstruits, mais aussi que les antiracismes peuvent aussi être reconstruits par l’entremise des relations éthiques, de la vérité et d’une pratique critique visant la réconciliation

    Preliminary evidence for human globus pallidus pars interna neurons signaling reward and sensory stimuli.

    The globus pallidus pars interna (GPi) is a component of the basal ganglia, a network of subcortical nuclei that process motor, associative, and limbic information. While non-human primate studies have suggested a role for the GPi in non-motor functions, there have been no single-unit studies of non-motor electrophysiological behavior of human GPi neurons. We therefore sought to extend these findings by collecting single-unit recordings from awake patients during functional stereotactic neurosurgery targeting the GPi for deep brain stimulation. To assess cellular responses to non-motor information, patients performed a reward task where virtual money could be won, lost, or neither, depending on their performance while cellular activity was monitored. Changes in the firing rates of isolated GPi neurons after the presentation of reward-related stimuli were compared between different reward contingencies (win, loss, null). We observed neurons that modulated their firing rate significantly to the presentation of reward-related stimuli. We furthermore found neurons that responded to visual-stimuli more broadly. This is the first single-unit evidence of human GPi neurons carrying non-motor information. These results are broadly consistent with previous findings in the animal literature and suggest non-motor information may be represented in the single-unit activity of human GPi neurons.NAH is supported by a Unilever/Lipton Graduate Fellowship in Neuroscience and a University of Toronto Fellowship.

    Grape Cultivar by Management System Trial Performance in 2007

    To identify grape cultivars adapted to Iowa, a cultivar by management system trial was established in 2002 at the Iowa State University (ISU) Horticulture Research Station (HRS) and the ISU Armstrong Research Farm (ARF) with a grant from the Leopold Center of Sustainable Agriculture. Fifteen cultivars, including ten wine and five seedless table cultivars, are being evaluated under 1) a conventional management system that relies on herbicides for weed control and application of insecticides and fungicides on a regular basis; 2) an IPM/best management system that uses herbicides as needed and relies on monitoring to determine the need for insecticides and fungicides; and 3) an organic approved system that relies on a straw mulch for weed control and use of organic-approved pest control strategies. This report summarizes the results for the 2007 growing season

    Reflection impulsivity in binge drinking: behavioural and volumetric correlates.

    The degree to which an individual accumulates evidence prior to making a decision, also known as reflection impulsivity, can be affected in psychiatric disorders. Here, we study decisional impulsivity in binge drinkers, a group at elevated risk for developing alcohol use disorders, comparing two tasks assessing reflection impulsivity and a delay discounting task, hypothesizing impairments in both subtypes of impulsivity. We also assess volumetric correlates of reflection impulsivity focusing on regions previously implicated in functional magnetic resonance imaging studies. Sixty binge drinkers and healthy volunteers were tested using two different information-gathering paradigms: the beads task and the Information Sampling Task (IST). The beads task was analysed using a behavioural approach and a Bayesian model of decision making. Delay discounting was assessed using the Monetary Choice Questionnaire. Regression analyses of primary outcomes were conducted with voxel-based morphometry analyses. Binge drinkers sought less evidence prior to decision in the beads task compared with healthy volunteers in both the behavioural and computational modelling analysis. There were no group differences in the IST or delay discounting task. Greater impulsivity as indexed by lower evidence accumulation in the beads task was associated with smaller dorsolateral prefrontal cortex and inferior parietal volumes. In contrast, greater impulsivity as indexed by lower evidence accumulation in the IST was associated with greater dorsal cingulate and precuneus volumes. Binge drinking is characterized by impaired reflection impulsivity suggesting a deficit in deciding on the basis of future outcomes that are more difficult to represent. These findings emphasize the role of possible therapeutic interventions targeting decision-making deficits.The study was supported by theWellcome Trust grant to VV (093705/10/Z) and to NA Harrison.

    To identify grape cultivars adapted to Iowa, a cultivar by management system trial was established in 2002 at the Iowa State University (ISU) Horticulture Research Station (HRS) and the ISU Armstrong Research Farm (ARF) with a grant from the Leopold Center of Sustainable Agriculture. Fifteen cultivars, including 10 wine and five seedless table cultivars, are being evaluated under 1) a conventional management system that relies on herbicides for weed control and application of insecticides and fungicides on a regular basis; 2) an IPM/best management system that uses herbicides as needed and relies on monitoring to determine the need for insecticides and fungicides; and 3) an organicapproved system that relies on a straw mulch for weed control and use of organic-approved pest control strategies. In 2008, the management systems treatments were discontinued, but still influenced the results. This report summarizes the results for the 2008 growing season
