The Impact of Conjugate Margins Analysis on Play Fairway Evaluation – An Analysis of the Hydrocrabon Potential of Nova Scotia

Assessment of the damage of one fishery by another requires knowledge of the overlap, in time and space, of the damaging fishing effort and the abundance of the damaged species, as well as a measure of the rate of damage. This approach was used to measure the impact of inshore scallop dragging on lobsters in Nova Scotia. Areas of reported co-occurrence of lobster and scallop grounds were surveyed by divers to determine the extent of overlap. Only 2 of 52 sites surveyed had lobsters on scallop grounds that could be dragged. Divers surveyed one site six times during 1987 and 1988 and found lobsters most abundant during August and September. Only 2% of the lobsters in the path of scallop drags were either captured or injured. The estimated value of lobsters destroyed by dragging for scallops during periods of peak lobster abundance was minor: $757 at one site and $176 at the other. Restricting dragging to periods of low lobster abundance significantly reduces this cost.

The Impact

Introduction: Blood transfusions continue to be a critical intervention in patients presenting to emergency departments (ED). Improved understanding of the adverse events associated with transfusions has led to new research to inform and delineate transfusion guidelines. The Nova Scotia Guideline for Blood Component Utilization in Adults and Pediatrics was implemented in June 2017 to reflect current best practice in transfusion medicine. The guideline includes a lowering of the hemoglobin threshold from 80 g/L to 70 g/L for transfusion initiation, to be used in conjunction with the patient's hemodynamic assessment before and after transfusions. Our study aims to augment understanding of transfusion guideline adherence and ED physician transfusing practices at the Halifax Infirmary Emergency Department in Nova Scotia. Methods: A retrospective chart review was conducted on one third of all ED visits involving red-cell transfusions for one year prior to and one year following the guideline implementation. A total of 350 charts were reviewed. The primary data abstracted for the initial transfusion, and subsequent transfusion if applicable, from each reviewed chart included clinical and laboratory data reflective of the transfusion guideline. Based on these data, the transfusion event was classified one of three ways: indicated based on hemoglobin level, indicated based on patient's symptomatic presentation, or unable to determine if transfusion indicated based on charting. Results: The year before guideline implementation, the total number of transfusions initiated at a hemoglobin of between 71-80 was 31 of 146 total transfusions. This number dropped by 23.6% to 22 of 136 in the year following guideline implementation. The number of single-unit transfusions increased by 28.0% from 47 of 146 in the year prior to 56 of 136 in the year after guideline implementation. The initial indication for transfusion being unable to be determined based on charting provided increased by 120%. The indication for subsequent transfusions being unable to be determined based on charting increased by 1500% (P < 0.05). Conclusion: These data suggest that implementing transfusion guidelines effectively reduced the number of transfusions given in the ED setting and increased the number of single-unit transfusions administered. However, the data also suggest the need for better education around transfusion indications and proper documentation clearly outlining the rationale behind the decision to transfuse.

Significant Economic Loss

The effect of galls induced by Hemadas nubilipennis Ashmead (Hymenoptera: Pteromalidae) on the morphology and reproduction of lowbush blueberry (Vaccinium angustifolium Aiton) was studied over two seasons in three Nova Scotia blueberry fields. Comparisons of galled and non-galled shoot characteristics, and position on shoots of galls formed in the years of vegetative and reproductive growth were made. In June 1999, 30 newly galled vegetative shoots were arbitrarily selected, tagged and measured along with similar sized non-galled shoots on the galled clone and a neighbouring non-galled clone. Shoot characteristics were measured in the reproductive season during bloom and after harvest. At two sites, the dry weights of leaves and stems on galled shoots measured in the reproductive season were significantly less than non-galled shoots, but at a third site there was no difference in stem allocation. Galls reduced berry production on shoots at two sites. Proportions of terminally positioned galls differed significantly among study sites in the reproductive season. Shoots with terminal galls were significantly shorter, lighter and allocated less weight to leaves and stems than shoots with basally positioned galls. If the reports of increasing gall populations in Nova Scotia during the 1990s are correct, there may be good reason to believe that there will be significant economic loss of blueberries in the future.

Abstract. The source attribution of observed variability of total PM2.5 concentrations over Halifax, Nova Scotia was investigated between 11 July–26 August 2011 using measurements of PM2.5 mass and PM2.5 chemical composition (black carbon, organic matter, anions, cations and 33 elements). This was part of the BORTAS-B (quantifying the impact of BOReal forest fires on Tropospheric oxidants using aircraft and satellites) experiment, which investigated the atmospheric chemistry and transport of seasonal boreal wild fire emissions over eastern Canada in 2011. The US EPA Positive Matrix Factorization (PMF) receptor model was used to determine the average mass (percentage) source contribution over the 45 days, which was estimated to be: Long-Range Transport (LRT) Pollution 1.75 μg m−3 (47%), LRT Pollution Marine Mixture 1.0 μg m−3 (27.9%), Vehicles 0.49 μg m−3 (13.2%), Fugitive Dust 0.23 μg m−3 (6.3%), Ship Emissions 0.13 μg m−3 (3.4%) and Refinery 0.081 μg m−3 (2.2%). The PMF model describes 87% of the observed variability in total PM2.5 mass (bias = 0.17 and RSME = 1.5 μg m−3). The factor identifications are based on chemical markers, and they are supported by air mass back trajectory analysis and local wind direction. Biomass burning plumes, found by other surface and aircraft measurements, were not significant enough to be identified in this analysis. This paper presents the results of the PMF receptor modelling, providing valuable insight into the local and upwind sources impacting surface PM2.5 in Halifax during the BORTAS-B mission.

The Impact

The objective of this research is to compare the economic benefits (defined as visitor spending) and costs of a UNESCO World Heritage (WH) designation. The study focuses on two sites in Nova Scotia; Old Town Lunenburg (designated as a WH site in 1995) and Grand Pré National Historic Site (which has applied for a WH status). Pre/post designation visitation data from Lunenburg was used to quantify the impact (6.2%) in the Nova Scotia context. A proportional (to visitation) impact was projected for Grand Pré. The analysis indicates that the level of visitation is important in determining economic viability and that the rising costs of a WH designation further challenge smaller scale attractions.

The Relationship

John McGahern, in his fiction and memoir, follows an ancient bardic tradition exemplified in our time by the poets Seamus Heaney and Sorley MacLean. This chapter takes a more personal approach to make connections between the author’s childhood in a small place on Cape Breton Island, Nova Scotia, and the early years of John McGahern, Seamus Heaney and Sorley MacLean, a Scottish poet. The chapter examines the author’s own formation as a journalist and novelist – a journey greatly influenced by McGahern and by the strong Irish and Scottish tradition of Breton Island - alongside that of the three writers. It explores the relationship between growing up on an island and a sense of isolation and inferiority that might go with it, and the impact that this kind of life might have had on McGahern’s, Heaney’s and MacSorley’s work and personality.

External Defibrillator

Introduction: The COVID-19 pandemic has led to widespread closures of non-essential businesses and buildings. The impact of such closures on public automated external defibrillator (AED) accessibility compared to mobility trends is unknown. Methods: We identified all publicly available online AED registries in Canada last updated May 1, 2019 or later. AEDs were classified by location type using addresses and registry notes, and deemed completely inaccessible, partially inaccessible, or unaffected using government-issued closure orders as of May 1, 2020. We mapped AED location types to categories used by Google’s COVID-19 Community Mobility Reports and calculated the median percent change in daily traffic between Feb. 15 - May 1, 2020 (excluding Apr. 10-12). We compared the percent of completely inaccessible AEDs to the median percent change in traffic for each category. Results: We identified three provincial (British Columbia, Alberta, Nova Scotia) and two municipal (Mississauga and Toronto in Ontario) online AED registries, collectively covering 13.1 million people. Of the 5,845 AEDs identified, 69.9% were completely inaccessible, 18.8% were partially inaccessible, and 11.3% were unaffected. AEDs in parks (n=141), almost all retail and recreational locations (n=1,539), and two-thirds of workplaces (n=3,633) were completely inaccessible, grocery and pharmacy-based (n=173) AEDs were partially inaccessible, and transit station (n=277) and residential (n=85) AEDs were unaffected. The largest discrepancies between AED accessibility and mobility occurred in parks (100% completely inaccessible vs. 10.5% traffic decrease), retail and recreation (99.0% completely inaccessible vs. 48.0% traffic decrease), and transit stations (100% unaffected vs. 63.0% traffic decrease). Conclusion: Government-mandated closures due to the COVID-19 pandemic have led to a greater reduction in AED accessibility than mobility in many locations across Canada.
