Abstract:
BackgroundIn May 2015, the Canadian province of Nova Scotia became the first jurisdiction in the world to ban menthol cigarettes specifically. The tobacco industry warned that ‘the primary effect of this law will be to increase the illegal tobacco market in Nova Scotia’. This is the first attempt to examine the impact of the menthol ban on trends in illicit cigarettes.Data and methodsData on the number of illicit cigarettes seized in Nova Scotia covering the period from 2007/2008 to 2017/2018 was obtained from the Provincial Tax Commission. Data from before and after the ban are compared.ResultsAccording to the local authorities, while the enforcement efforts in Nova Scotia have not declined, the number of seized illicit cigarettes declined significantly, from >60 000 cartons in 2007/2008 to <10 000 cartons in 2017/2018. Since the menthol ban, the seizure volume remained stable, with no statistically significant difference in the number of cigarettes seized before and after the menthol ban (t=−0.71, p=0.55). There were only a few small seizures of menthol cigarettes in the year following the ban, after which there have been no further seizures of menthol cigarettes.DiscussionContrary to the tobacco industry’s assertions, there was no surge in illicit cigarettes after the 2015 ban on menthol cigarette sales in Nova Scotia. Credible, industry-independent evidence on illicit cigarette trade is desperately needed to support the implementation of tobacco control policies.

Abstract:
Studies from the 1980s concluded that aluminum (Al) was not a significant contributor to Atlantic salmon ( Salmo salar ) toxicity in Nova Scotia, located on Canada’s Atlantic coast, because of the presence of dissolved organic matter that rendered ionic Al (Ali) biologically inaccessible. Since this earlier work, new interpretations of Ali effects, as well as improved techniques for its measurement, have been developed. However, no new data interpretation has been done to see if the conclusions reached in earlier work for Atlantic Canada were still valid. We sampled 97 salmon rivers from the provinces of New Brunswick (NB), Nova Scotia (NS), and the island of Newfoundland (NF) to determine total and Ali concentrations to see if results exceeded newer toxicity standards established by the European Inland Fisheries Advisory Commission. We found that southwestern NS, the region with the greatest loss of salmon populations, has seven rivers where autumn Ali values exceed values identified as toxic to aquatic life. A further three rivers exceed guidelines in NF. Our work shows that the sources of toxicity for salmon and other aquatic species in acidified environments are more complex than previously thought.

Abstract:
A total of 85 species of fish are known or suspected from Minas Basin and Minas Passage, Nova Scotia, Canada. This systematic review details their seasonal occurrence, habitat, abundance, migratory behavior, fisheries and potential impact from tidal power development. The fish assemblage is a mixture of species common to the Bay of Fundy and the Atlantic coast of Nova Scotia as well as numerous warm- and cold-water visitors seldom found elsewhere in Canada. Minas Basin fisheries exploit some species especially those that migrate through the Basin during summer. Fishes were captured or observed using angling, seines, benthic long lines, drift and fixed gill nets, intertidal fish weirs, bottom trawls and sightings while on vessels. Fishes are categorized with respect to their taxonomic diversity, seasonal occurrence, status, fisheries and the potential impact from tidal lagoons and propeller turbines resulting from development of tidal power in Minas Basin and Minas Passage. Keywords: Bay of Fundy, habitat, species status, propeller turbines, taxonomic relationship, tidal lagoons.

Abstract:
The strong tidal currents of the Minas Passage in the Bay of Fundy, Nova Scotia, have made this area an important site for testing and development of tidal power technologies. Understanding sediment processes in this area is essential for determining the impacts that large-scale tidal power extraction would have on the system. Previous estimates of sediment input to the Basin suggest that much more sediment enters the Basin than accumulates within it; therefore, the bottom sediment texture should be in hydrodynamic equilibrium with bottom currents. A recent study, however, showed that sediment texture is generally finer that what was expected based on current speeds. This paper uses geographic information systems methods to provide updated and more highly resolved measurements of the amount of sediment entering the Minas Basin from the dominant source, which is coastal erosion. Volumetric input from coastal erosion is 1.1 × 106 m3·a−1, which is more than two times smaller than previous estimates. This updated value makes input rates comparable to accumulation rates, and agrees with the hypothesis that bottom sediment texture is not in equilibrium with current speeds. Grain-size distributions also support the hypothesis that the Minas Basin acts as a sediment trap.

Abstract:
Abstract Following the recommendations of the Royal Commission on Bilingualism and Biculturalism, the Canadian and provincial governments undertook a wide array of measures to promote Canada's two official languages through education programs. Over the fifteen years following the passage of the Official Languages Act, minority and second official-language education programs developed in a markedly different fashion in the two provinces with the largest Acadian communities: New Brunswick and Nova Scotia. A combination of factors, including the demographic weight of the Acadian communities, the strategies of Acadian lobby groups, the attitudes of the majority and minority communities, and the ideologies of key politicians and civil servants must all be taken into account to explain the uneven development of official language education programs in these two “Acadian provinces”.

Abstract:
The growing need for reducing the negative impacts of climate change and ensuring a constant and environmentally friendly energy supply, led the way to the exploitation of renewable energy sources. Canada has already acknowledged this trend by incorporating more power from renewables on its energy mix. Similarly, Nova Scotia has started an ambitious energy program in which the substitution of most of the fossil fuels by wind energy, will play a significant factor. The purpose of this research is to investigate all suitable locations for wind energy development in the province of Nova Scotia, under the scope of minimizing environmental impacts, increasing social acceptance and maximizing energy production. This spatial analysis is performed through the combination of Geographical Information Systems (GIS) and a Multi Criteria Decision Analysis (MCDA). The analysis of the province was based on the preferences of wind experts and administration authorities, which formed the weights assigned on eight (8) evaluation criteria. The extract of the relative weights was succeeded by using the Analytical Hierarchy Process (AHP), while their spatial dimensions were expressed by GIS software. The above procedure was possible through the application of a methodology where exclusion areas were found on the first place and the remaining areas were assessed on their level of suitability. The implementation of the GIS-MCDA methodological framework indicates that, despite the exclusion of a significant part of the province, there is still enough space to develop wind energy. The applied methodology and relevant results could be used as a Decision-Making tool by planning authorities, wind developers, and stakeholders.

Abstract:
Community power is an alternative to the fossil-fuelled, centralized approach to electricity generation. Typically, community power involves low-carbon or renewable forms of electricity generation developed in relatively small generation facilities distributed geographically, entirely or in part owned by the local community. Community power has been found to improve the efficiency of energy systems by decreasing transmission losses and making better use of the heat by-product. Other benefits include increased community acceptance of renewable energy technologies, expedited deployment of renewable technologies, and rural economic development. This study identified how the Canadian province of Nova Scotia could develop a viable community power sector by learning from leaders in the field, namely Denmark and Ontario. Case studies of these leading jurisdictions were developed through literature reviews and interviews with key informants. Next, the conditions for success for community management of common pool resources were compared to the case studies to draw parallels between conditions for success in community power sectors in Denmark and Ontario. It was found that many of the conditions for successful community management of common pool resources were similar to those that realized viable community power sectors with the exception of ‘the relationship between the resource system and institutional arrangements.’ The conditions fell under the themes of: ‘resource system characteristics;’ ‘group characteristics;’ ‘the relationship between resource system and group characteristics;’ ‘institutional arrangements;’ and ‘the external environment.’ At the time of study, Nova Scotia was taking the initial steps to creating a community power sector. By way of interviews with key informants in the province, barriers to a viable community power sector were identified. Next, drawing from the experiences of the Denmark and Ontario, methods to overcome the barriers were identified. Recommendations for the Nova Scotia Departments of Energy, the Department of Economic and Rural Development and Tourism, the Department of Natural Resources, CEDIF businesses, municipalities, renewable power proponents, and academic institutions were concluded from this study. The recommended path will enable a successful community power sector in Nova Scotia, which will in turn help achieve the provincial renewable electricity targets, enable a more stable and efficient energy system, and increase economic prosperity, particularly in rural communities. The recommendations are specific to Nova Scotia, although they may inform steps to successful community power sectors in similar jurisdictions.

Abstract:
The present chapter traces the emergence of Scottish Atlantic writing in the seventeenth century by focusing on works from the 1620s that promote the colonization of Nova Scotia. It studies works written by James VI and I, William Alexander, Robert Gordon, Thomas Hariott, and Richard Guthry while also discussing the role the Virginia Company and the indigenous Mi'kmaq and Maliseet populations played in Scotland's attempts to colonize Nova Scotia. It situates these agents and works in the larger contexts of European empire-building. It also considers forms of internal colonialism in the British Isles, including writings about the Highlands and Islands and inner-British power dynamics after the Union of Crowns. The utopian tradition offers ways to understanding the spaces, temporalities, and cultural agents in the emerging Scottish Atlantic, including the tropes of newness and reform as well as the intertextual relationships with earlier travelogues and the longevity of the Scottish colonial imagination.

Abstract:
This chapter describes how, from 1792 to 1800, black colonists in Freetown, Sierra Leone—also referred to hereafter as “black Loyalists” and “Nova Scotians”—won several battles in the fight against black hunger. The Nova Scotians arrived in Africa in 1792 imbued with a sense of how to use food laws to exert dominance, and within half a decade, they had learned to behave as British subjects entitled to enforce that power. Whereas in Nova Scotia white Loyalists' food laws had controlled former bondpeople's access to food, in Sierra Leone, black colonists gained the right to enact their own antihunger rules, which white colonists uniformly approved, beginning in 1793. These Nova Scotians fought famine first by regulating their trade in alcohol, bread, fish, and meat. Later, the black Loyalists tried to regulate the trade of Africans, particularly Susu and Temne. These laws enabled former victual warriors to try to become victual imperialists by altering African food sales while occupying African land. This attempt failed because violent Temne and Susu reactions to colonists' price-fixing encouraged white councilmen in Sierra Leone to curtail black Loyalist lawmaking; those councilmen would later try to interfere with Africans' trade.

Abstract:
This introductory chapter discusses the important role of hunger during the American Revolution. Enduring, ignoring, creating, and preventing hunger were all ways to exercise power during the American Revolution. Hunger prompted violence and forged ties; it was a weapon of war and a tool of diplomacy. In North America, Cherokee, Creek, Delaware, Iroquois (Haudenosaunee), Miami, and Shawnee Indians grew and destroyed foodstuffs during the Revolutionary War, which forced their British and American allies to hunger with them, and to furnish provisions that accommodated Native tastes. By the 1810s, the United States had learned how to prevent Indian hunger, to weaponize food aid, and to deny Indians the power gained by enduring and ignoring scarcity. Meanwhile, people of African descent gained some power by creating white hunger during the Revolutionary War, but more so as formerly enslaved communities, primarily after leaving the new United States and migrating to British colonies in Nova Scotia and then Sierra Leone. After white officials in Sierra Leone realized that colonists' hunger-prevention efforts gave them too much freedom, black colonists lost their hunger-preventing rights. Ultimately, three key behaviors changed and were, in turn, changed by evolving ideas about hunger: food diplomacy, victual warfare, and victual imperialism.

Abstract:
Ocean energy developments are appearing around the world including Scotland, Ireland, Wales, England, Australia, New Zealand, Japan, Korea, Norway, France Portugal, Spain, India, the United States, Canada and others. North America’s first tidal energy demonstration facility is in the Minas Passage of the Bay of Fundy, near Parrsboro, Nova Scotia, Canada. The Fundy Ocean Research Center for Energy (FORCE) is a non-profit institute that owns and operates the facility that offers developers, regulators, scientists and academics the opportunity to study the performance and interaction of instream tidal energy converters (usually referred to as TISECs but called “turbines” in this paper.) with one of the world’s most aggressive tidal regimes. FORCE provides a shared observation facility, submarine cables, grid connection, and environmental monitoring at its pre-approved test site. The site is well suited to testing, with water depths up to 45 meters at low tide, a sediment -free bedrock sea floor, straight flowing currents, and water speeds up to 5 meters per second (approximately 10 knots). FORCE will install 10.896km of double armored, 34.5kV submarine cable — one for each of its four berths. Electricity from the berths will be conditioned at FORCE’s own substation and delivered to the Provincial power grid by a 10 km overhead transmission line. There are four berth holders at present: Alstom Hydro Canada using Clean Current Power Systems Technology (Canada); Minas Basin Pulp and Power Co. Ltd. with technology partner Marine Current Turbines (UK); Nova Scotia Power Inc. with technology partner OpenHydro (Ireland) and Atlantis Resources Corporation, in partnership with Lockheed Martin and Irving Shipbuilding. In November 2009, NSPI with technology partner OpenHydro deployed the first commercial scale turbine at the FORCE site. The 1MW rated turbine was secured by a 400-tonne subsea gravity base fabricated in Nova Scotia. The intent of this paper is to provide an overview of FORCE to the international marine energy community during OMAE 2011 taking place in Rotterdam, Netherlands.

Abstract:
Ocean ice capable of impacting marine operations occurs periodically in the most favorable sites for energy harvest from the tidal currents of the Bay of Fundy in Nova Scotia and New Brunswick. In-stream tidal current harvesting devices deployed at these sites should to be engineered to tolerate at least 30% ice cover with 15 cm (6 inch) thick floes at least 100 metres in length. Propelled by tidal currents and prevailing winds, ice floes may achieve velocities in excess of 8 knots in some locations. In very severe winters, in-stream tidal current harvesting devices may be subjected to periods of 90% cover of rapidly moving or packed ice thicker than 30 cm (12 inches). Markets for ice-tolerant tidal current harvesting devices developed under the moderate ice conditions in the headwaters of the Bay of Fundy may exist in other jurisdictions with energetic tidal flows which experience more severe conditions of ocean ice.

Abstract:
Large tidal currents exist in Minas Passage, which connects Minas Basin to the Bay of Fundy off the northwestern coast of Nova Scotia. The strong currents through this deep, narrow channel make it a promising location for the generation of electrical power using instream turbines. These strong currents are clearly illustrated in the results of a high-resolution, three-dimensional model of the flow through Minas Passage presented here. The simulations also clearly indicate the asymmetry of the flood and ebb tides and the 3D structure of the flow. A previous study has indicated that as much as 7000 MW could be extracted from the tidal currents through Minas Passage. However, this estimate was based on a complete fence of turbines across the passage, in essence a tidal barrage. In this paper, the power potential of partial turbine fences is examined. In order to estimate the power potential of turbine arrays, the theory of partial turbine fences is adapted to the particular dynamics of Minas Passage. The theory estimates the potential power of the fence and the change in flow that would result. The results are presented in terms of the portion of the cross-sectional area that the turbines occupy and the drag coefficient of the turbines. When the turbine fence occupies a large portion of the passage, the potential power of the fence rises significantly, to a value much larger than estimates based on the kinetic energy flux. The increase in power comes from the increased tidal head that a large turbine fence creates and the resulting increase in the turbine drag. We also present the efficiency of the turbine fence — given as the ratio of the power associated with the turbine drag over the total power extracted from the flow — and the impact of the turbines on the tidal flow. The results of the theory are compared to numerical simulations of the flow through the passage with turbines represented as regions of increased drag. The numerical simulations give power values that are three to six time as high as the theory suggests is possible. This discrepancy is examined by plotting the changes in tidal currents caused by the turbine fence.

Abstract:
When looking for a location for a wave energy converter (WEC) installation, developers usually look for sites with high or very high wave energy resource. From this perspective, countries like Scotland or Ireland have made great effort to include this energy source in their energy mix due to their expected high untapped potential. However, higher resource carries marine operation restrictions. Because of that, the selection of a site for a WEC deployment, the installation, operation and maintenance factors have to be considered from the beginning. In this work an analysis of the suitable locations for the development of wave energy is performed based on the operation and maintenance (O&M) parameters. This study is performed across the globe coastlines taking the met-ocean climate data from Reguero et al (2011) global reanalysis database (GOW) developed at IH Cantabria. Firstly, an analysis of the global availability and accessibility levels is performed all around the globe taking different wave height thresholds into account. Seven specific locations (North-West Denmark, West of Ireland, Chile, North of Spain, West Portugal, South-West Australia and North of Scotland) with high interest on wave energy have been further analyzed and compared. Secondly, the O&M access limits are quantified in terms of the weather windows and the waiting period between available weather windows. A statistical analysis of these parameters is performed within different weather windows lengths (6 h, 12 h and 24 h). The seasonality of these parameters is also analyzed. Finally, a failure analysis will be carried out, simulating the repair operation along the lifecycle of the device for different failure rates and waiting times. The affection of this failure and repair scheme over the power production of a device analyzed previously in Andres et al (2014) will be presented. In this study, some locations with high resource (Spain, Nova Scotia) lead to medium to high accessibilities/availabilities due to the balance between resource and persistence of the weather conditions. Some locations with high resource such as Chile or Australia resulted inaccessible during very long periods of time due to the persistence of severe conditions and then not very recommended for novel converters with uncertain failure rates.
