Community-level risk factors for notifiable gastrointestinal illness in the Northwest Territories, Canada, 1991-2008
Aliya Pardhan-Ali, Jeff Wilson, Victoria L Edge, Chris Furgal, Richard Reid-Smith, Maria Santos, Scott A McEwen
BMC Public Health , 2013, DOI: 10.1186/1471-2458-13-63
Abstract: The rate of campylobacteriosis was modeled using a Poisson distribution while rates of giardiasis and salmonellosis were modeled using a Negative Binomial distribution. Rate ratios (the ratio of the incidence of disease in the exposed group to the incidence of disease in the non-exposed group) were estimated for infections by the three major pathogens with potential community-level risk factors.Significant (p≤0.05) associations varied by etiology. There was increased risk of infection with Salmonella for communities with higher proportions of ‘households in core need’ (unsuitable, inadequate, and/or unaffordable housing) up to 42% after which the rate started to decrease with increasing core need. The risk of giardiasis was significantly higher both with increased ‘internal mobility’ (population moving between communities), and also where the community’s primary health facility was a health center rather than a full-service hospital. Communities with higher health expenditures had a significantly decreased risk of giardiasis. Results of modeling that focused on each of Giardia and Salmonella infections separately supported and expanded upon previous research outcomes that suggested health disparities are often associated with socioeconomic status, geographical and social mobility, as well as access to health care (e.g. facilities, services and professionals). In the campylobacteriosis model, a negative association was found between food prices in communities and risk of infection. There was also a significant interaction between trapping and consumption of traditional foods in communities. Higher rates of community participation in both activities appeared to have a protective effect against campylobacteriosis.These results raise very interesting questions about the role that traditional activities might play in infectious enteric disease incidence in the NWT, but should be interpreted with caution, recognizing database limitations in collection of case data and ris
A spatial and temporal analysis of notifiable gastrointestinal illness in the Northwest Territories, Canada, 1991-2008
Aliya Pardhan-Ali, Olaf Berke, Jeff Wilson, Victoria L Edge, Chris Furgal, Richard Reid-Smith, Maria Santos, Scott A McEwen
International Journal of Health Geographics , 2012, DOI: 10.1186/1476-072x-11-17
Abstract: There was geographic variability in the rates of NGI with higher notifications in the south compared to the north. Incidence of NGI exhibited seasonality with peaks in the fall months for most years. Two possible outbreaks were detected in the fall of 1995 and 2001, of which one coincided with a previously recognized outbreak. Overall, incidence of NGI fluctuated from 1991 to 2001 followed by a tendency for rates to decrease from 2002 to 2008.The distribution of NGI notifications varied widely according to geographic region, season and year. While the analyses highlighted a possible bias in the surveillance data, this information is beneficial for generating hypotheses about risk factors for infection.

BMC Public Health , 2006, DOI: 10.1186/1471-2458-6-307
Abstract: The magnitude and distribution of acute GI in British Columbia (BC), Canada was evaluated via a cross-sectional telephone survey of 4,612 randomly selected residents, conducted from June 2002 to June 2003. Respondents were asked if they had experienced vomiting or diarrhoea in the 28 days prior to the interview.A response rate of 44.3% was achieved. A monthly prevalence of 9.2% (95%CI 8.4 – 10.0), an incidence rate of 1.3 (95% CI 1.1–1.4) episodes of acute GI per person-year, and an average probability that an individual developed illness in the year of 71.6% (95% CI 68.0–74.8), weighted by population size were observed. The average duration of illness was 3.7 days, translating into 19.2 million days annually of acute GI in BC.The results corroborate those from previous Canadian and international studies, highlighting the substantial burden of acute GI.Gastrointestinal illness (GI) is a global public health concern. In developed countries, GI is typically mild and self-limiting, but has considerable economic impact due to high morbidity [1-3]. Recent studies on the burden of GI in the general population of a number of countries have been reported [4-12]. To estimate the burden of GI in the Canadian population, the Public Health Agency of Canada (PHAC; formerly Health Canada) developed the National Studies on Acute Gastrointestinal Illness (NSAGI) initiative in 2000. Population-based studies, designed to describe self-reported, acute GI in selected Canadian populations, are part of this initiative. In March 2002, the PHAC completed the first such population study in the City of Hamilton, Ontario, Canada [13]. In order to determine if the burden of GI was the same across the country, a second population study was completed in the province of British Columbia (BC) in June 2003. Additionally, since public health in Canada is primarily a provincial responsibility, this study was conducted to provide information to BC policy makers. The current paper describes the frequen
A Giant Arc in a ROSAT Detected Cluster of Galaxies

Physics , 1994,
Abstract: We report the serendipitous discovery of a giant grvitational arc in the Abell Supplementary cluster S295 during optical follow-up observations of clusters detected in the ROSAT All-Sky Survey. The cluster has a redshift z=0.3007 and a velocity dispersion of about 900 km/sec. This is the first giant arc newly found in a ROSAT Survey cluster, indicating the potential advantage of searching for giant arcs in X-ray selected clusters.
Examination of Complementarity in Speech and Emotional Vocalization Perception  [PDF]
Victoria L. Harms, Lorin J. Elias
Psychology (PSYCH) , 2014, DOI: 10.4236/psych.2014.58098
Abstract:

Lateralization of cognitive functioning is a well-established principle of cerebral organization. The left and right hemispheres are known to play distinct and complementary roles in the processing of information. What is still unclear is whether these asymmetrically lateralized functions have a common or distinct developmental origin; are left and right processes lateralized through causal influences, or is the laterality of each function independently influenced? Left- and right-lateralized functions are commonly assessed in isolation, with little attention to the relationship in the degree and direction of lateralization within individuals. This relationship between left-hemisphere processing of speech sounds and right-hemisphere processing of emotional vocalizations was examined using dichotic listening tasks. An overall complementary pattern of lateralization was observed across participants, but no significant relationship was found for degree of lateralization of speech and emotional vocalization processing within individuals. These results support the view that functions in the left and right hemispheres are independently lateralized.

The place of quality assurance in managing animal welfare during long distance transport
John L. Barnett,Michelle K. Edge,Paul H. Hemsworth
Veterinaria Italiana , 2008,
Abstract: The authors describe the development of an animal welfare component of a quality assurance (QA) programme for the land transportation of livestock in Australia. Relationships among animal welfare practices on farms, during transport and at destinations require an approach that covers the entire production chain. The need for QA programmes includes increased awareness in the transport industry that animal welfare is an issue that engages the broader community and recognition that contentious welfare standards are discussed in the public domain and that public attitudes influence animal welfare standards. Three booklets have been produced that cover animal welfare issues in transport for the major commercial livestock species. Strategies for implementation of QA in industry have also been developed. The welfare standards have been incorporated into the transport industry's QA programme. QA programmes need to be acceptable to the community, be able to meet all customers' requirements and demonstrate to government authorities that they provide appropriate confidence that animal welfare standards have been met. The full impact of QA programmes will be fully appreciated when their ability to deliver comprehensive benefits and continual improvements in animal welfare has been evaluated.
The role of spin-orbit coupling in topologically protected interface states in Dirac materials
D. S. L. Abergel,Jonathan M. Edge,Alexander V. Balatsky
Physics , 2014, DOI: 10.1088/1367-2630/16/6/065012
Abstract: We highlight the fact that two-dimensional materials with Dirac-like low energy band structures and spin-orbit coupling will produce linearly dispersing topologically protected Jackiw-Rebbi modes at interfaces where the Dirac mass changes sign. These modes may support persistent spin or valley currents parallel to the interface, and the exact arrangement of such topologically protected currents depends crucially on the details of the spin-orbit coupling in the material. As examples, we discuss buckled two-dimensional hexagonal lattices such as silicene or germanene, and transition metal dichalcogenides such as MoS$_2$.

Las intrincadas relaciones entre investigación, desarrollo e innovación con progreso y bienestar y la importancia de su divulgación
Victoria López Rodas
Circunstancia , 2008,
Abstract: Entre los temas prioritarios en divulgación científica está el explicar porqué hay que invertir esfuerzo y dinero en ciencia y tecnología. A menudo se argumenta que la pujanza económica de un país está íntimamente ligada a su capacidad para la innovación y que ésta a su vez depende de la inversión estatal en investigación básica y aplicada. El rápido crecimiento de EEUU durante el siglo XX se pone a menudo como ejemplo de sociedad innovadora resultante de una elevada inversión estatal. Sin embargo la realidad es mas compleja y no siempre las grandes inversiones estatales en I+D+i han sido garantía de desarrollo económico. Además de la inversión, también se necesita un conjunto de actitudes sociales frente a la ciencia (tradición científica-tecnológica). Como la capacidad para hacer Ciencia es una de las características esenciales de los seres humanos, invertir en Ciencia y difundirla es, sin duda, alguna invertir en Humanidad.
