“Knowledge Translation in a Community-Based Study of the Relations Among Violence Exposure, Post- Traumatic Stress and Alcohol Misuse in Mi’kmaq Youth”

In 2004, our research group was invited to continue a research partnership with a Nova Scotian Mi’kmaq community that was concerned about the causes of and interventions for adolescent alcohol misuse in their community. While our previous collaborative research focused on reducing adolescent alcohol misuse by targeting motivations for drinking that were personality specific (see Mushquash, Comeau, & Stweart, 2007), the more recent collaboration sought to investigate the possible relationship between exposure to violence, post-traumatic stress, and alcohol misuse. The present paper outlines the steps involved in gaining community consent, the plan for results sharing, the tangible benefits to the community that have been documented, and future directions and lessons learned. The paper will demonstrate how the principles of Knowledge Translation (CIHR, 2006) provide a framework for this process

Building a Collaborative Understanding of Pathways to Adolescent Alcohol Misuse in a Mi’kmaq Community: A Process Paper

In April of 2006, a team of researchers consisting of both university and community partners from a Mi’kmaq reserve in Nova Scotia began the data-collection phase of a high school-based research study that had been two years in planning. The study examines the possible relationships between youth-reported childhood maltreatment, posttraumatic stress disorder (PTSD) symptoms, depressive symptoms, alcohol misuse, and resiliency factors. The aim of the research study is to provide information about adolescent alcohol misuse that is of practical benefit to community-based service providers, and capable of making a scholarly contribution to the scientific study of the relations of anxiety/mood symptoms and addictive behaviours. The primary aim of this paper is to present both the context from which the project grew, and the steps involved in conducting research with our school partners and the community service providers. Asecondary aim is to present some of the preliminary data from the study, with a specific focus on resiliency

The influence of gas velocity, salt type and concentration on transition concentration for bubble coalescence inhibition and gas holdup

The influence of gas velocity (3.5, 10, and 18mm/s), salt type (NaCl, NaF, NaBr, NaI and CsCl) and salt concentration (0.001–3M) on bubble coalescence in a small bubble column were studied. The bubble coalescence was determined by the relative change in the measured light intensities passing through the salt solutions and clean deionised water. It was shown that the transition salt concentration for bubble coalescence inhibition (determined at 50% of bubble coalescence) of all investigated salts decreases with increasing superficial gas velocity. The difference in the transition concentration between NaCl, NaF, NaBr and CsCl does not significantly change with the gas velocity. However that difference between NaI and the other salts significantly decreases with increasing the gas velocity. The gas holdup significantly increases with NaCl, NaF, NaBr and CsCl concentrations but does not significantly change with NaI concentration. These new results imply that the transition salt concentration for bubble coalescence and gas holdup depend not only on the salt properties (i.e. the ion type and their combination) as previously reported, but also on the hydrodynamic conditions

First bulk and surface results for the ATLAS ITk Strip stereo annulus sensors

A novel microstrip sensor geometry, the stereo annulus, has been developed for use in the end-cap of the ATLAS experiment's strip tracker upgrade at the HL-LHC. Its first implementation is in the ATLAS12EC sensors a large-area, radiation-hard, single-sided, ac-coupled, \ninp design produced by the ITk Strip Sensor Collaboration and fabricated by Hamamatsu Photonics in early 2017. The results of the initial testing of two ATLAS12EC batches are presented here with a comparison to specification. The potential of the new sensor shape to reinvigorate endcap strip tracking is explained and its effects on sensor performance are isolated by comparing the bulk mechanical and electrical properties of the new sensor to the previous iteration of prototype, the conventional barrel ATLAS12A sensor. The surface properties of the new sensor are evaluated for full-size unirradiated sensors as well as for mini sensors unirradiated and irradiated with $p^{+}$ up to a fluence of $2.2 \times 10^{15}$\neqsq. The results show that the new stereo annulus ATLAS12EC sensors exhibit excellent performance and the expected irradiation evolution

Neuroanatomy and Neuroimaging of Anxiety Disorders

Neuroimaging methods can be used to examine functional brain differences between healthy individuals and those with anxiety disorders. After the brain regions implicated in the pathophysiology of anxiety disorders (e.g., amygdalo-cortical circuitry) are reviewed, neuroimaging studies of posttraumatic stress disorder (PTSD), social anxiety disorder (SAD), specific phobia (SP), and panic disorder (PD) that report activations in these regions are discussed. Studies of obsessive-compulsive disorder (OCD) implicate a distinct neurocircuitry profile (i.e., cortico-striatal-thalamic circuit) compared to the other anxiety disorders. Few neuroimaging studies of generalized anxiety disorder (GAD) have been conducted. In addition, results from functional connectivity analyses and the effects of treatment on neuroimaging findings are summarized
