Surface electroencephalogram (EEG) recording remains the gold standard for noninvasive assessment of electrical brain activity. It is the most efficient way to diagnose and classify epilepsy syndromes as well as define the localization of the epileptogenic zone. The EEG is useful for management decisions and for establishing prognosis in some types of epilepsy. Electroencephalography is an evolving field in which new methods are being introduced. The Canadian Society of Clinical Neurophysiologists convened an expert panel to develop new national minimal guidelines. A comprehensive evidence review was conducted. This document is organized into 10 sections, including indications, recommendations for trained personnel, EEG yield, paediatric and neonatal EEGs, laboratory minimal standards, requisitions, reports, storage, safety measures, and quality assurance.

Background: Community care workers’ experience of delivering support to people with dementia is less researched than that of residential workers. The purpose of the study is to explore community-based dementia care workers’ perspectives about their roles and the contextual variables that impact upon their work experiences.
Method: A qualitative design was employed. Twenty-five community dementia care workers (average age 53 years, majority female and employed casually) participated in standardized semi-structured interviews about their job roles, training, employer agenda, organizational support, and intention to stay. A deductive approach to Interpretive Phenomenological Analysis was adopted to identify key themes.
Results: Three themes highlighted workers’ experiences. Occupational communion described strong attachment to clients and a desire for greater connection with colleagues. Job demands described the challenges of work, which varied with intensity. Job resources ranged from positive (strong organizational commitment) to negative (poor pay and conditions). Occupational communion was identified as a concept that exists at the interface between social and organization psychology that was perceived to be essential for adaptive coping. Identifying themes informed a conceptual model for designing intervention components aimed at improving workers’ skills, capabilities, and employer supportive functions.
Conclusion: Occupational communion may be particularly relevant for women's caring careers and future research is needed to explore the relevance of this concept for men. To determine reliable change associated with interventions that target occupational communion, further investigation is required in relation to measurement approaches.

Background: Dementia increasingly impacts every health and social care system in the world. Preparing the dementia care workforce is therefore paramount, particularly in light of existing problems of staff retention and turnover. Training interventions will need to increase worker and organizational capacity to deliver effective patient care. It is not clear which training interventions best enhance workers’ capacity. A review of the evidence for dementia care training interventions to enhance worker capacity and facilitate organizational change is presented.
Methods: A systematic literature review was conducted. All selected randomized intervention studies aimed to enhance some aspect of dementia care worker or workforce capacity such as knowledge of dementia, psychological well-being, work performance, and organizational factors such as retention or service delivery in dementia care.
Results: Seventy-four relevant studies were identified, but only six met inclusion criteria for the review. The six studies selected focused on worker and organizational outcomes in dementia care. All interventions were multi-component with dementia education or instructional training most commonly adopted. No interventions were found for the community setting. Variable effects were found for intervention outcomes and methodological concerns are raised.
Conclusion: The rigor of scientific research in training interventions that aim to build capacity of dementia care workers is poor and a strong need exists for evaluation and delivery of such interventions in the community sphere. Wider domains of interest such as worker psychological health and well-being need to be examined further, to understand capacity-building in the dementia care workforce.

Rock weathering plays an important role in soil development. A better understanding of how different temperature and moisture regimes impact on the rates of rock breakdown can thus contribute to our knowledge of how rates of soil production might be affected by changes in climate. Laboratory simulations using two temperature cycles determined from field data and three moisture levels were carried out on samples of granite from three locations along the Victoria Land coast. Estimates of weathering rate from these experiments were of the same order of magnitude as some other more field based studies undertaken in similar environments. However, actual values for samples from the three locations varied depending on the specific characteristics of the rock, especially grain size, porosity and extent of micro-cracking. Moisture availability was found to be an important factor in determining weight loss in the samples from Gneiss Point but not in those from Terra Nova Bay or Teall Island with the moderate level of moisture application having the greatest impact. Spring/autumn temperature cycles had a different effect on the breakdown of the rock samples compared to summer cycles but the magnitude of the effect was dependent on moisture level and rock characteristics, especially quartz content and the ability to absorb heat and moisture. The samples of rock from Terra Nova Bay and Gneiss Point where no moisture had been applied had significantly higher rates of breakdown under spring/autumn cycles than summer ones. However, this effect was reversed in the Gneiss Point samples after moisture was added. A future climate scenario using the weathering rates found in this research where there was, for example, a 10% increase in summer temperature cycles and a corresponding decrease in spring/autumn cycles predicted that a reduction in weathering would occur in conditions of little or no precipitation at Terra Nova Bay and Gneiss Point but there would be limited effect under higher levels of moisture.

Candidates for coronary artery bypass graft surgery have been found to exhibit reduced cognitive function prior to surgery. However, little is known regarding the factors that are associated with pre-bypass cognitive function. A battery of neuropsychological tests was administered to a group of patients listed for bypass surgery (n = 109). Medical, sociodemographic and emotional predictors of cognitive function were investigated using structural equation modeling. Medical factors, namely history of hypertension and low ejection fraction, significantly predicted reduced cognitive function, as did several sociodemographic characteristics, namely older age, less education, non-English speaking background, manual occupation, and male gender. One emotional variable, confusion and bewilderment, was also a significant predictor whereas anxiety and depression were not. When significant predictors from the three sets of variables were included in a combined model, three of the five sociodemographic characteristics, namely age, non-English speaking background and occupation, and the two medical factors remained significant. Apart from sociodemographic characteristics, medical factors such as a history of hypertension and low ejection fraction significantly predicted reduced cognitive function in bypass candidates prior to surgery.
