Resumen

ABSTRACT The consideration in Canada of risk analysis for microorganisms in food by the Health Protection Branch (HPB) is in its formative stage. These analyses have become necessary because of the need for better control of imported and domestically produced food. A working group has been established between Health Canada and Agriculture and Agrifood Canada to consider a joint approach to risk analysis for foodborne microbiological hazards. Within the Bureau of Microbial Hazards of the HPB four health-risk determinations have been initiated. Three of these are for broad categories of products: dairy, fish and shellfish, and meat and poultry. These are meant as background documents for more specific risk assessments. The fourth, on cracked eggs, is designed to give management options for the control of this commodity. These determinations are being developed as required and different approaches are being considered. The working group is in agreement that standard definitions of terms and methodologies need to be used, and that these should come from discussions with other national and international agencies and associations, such as the Codex Alimentarius Commission. Recommendations include the need both for risk analysis to provide a clear process for food control by government and industry, and for directed research and surveys to provide more information on the status of hazards at different stages of specific processes from preharvest to consumer handling.

Resumen

Literature on sustainable agriculture was examined using qualitative research methods to identify institutional barriers to the transition to sustainable agriculture, and solutions to overcome them. Information was also collected from different participants in the food and agriculture system by conducting interviews and workshops, and by soliciting comments on discussion papers of preliminary findings.
An explanatory scheme (or general theory) was developed to organize strategies for overcoming institutional barriers using an efficiency--substitution--redesign framework. Efficiency strategies involve minor changes to existing activities, resulting in more efficient resource use. Substitution strategies involve replacing one product, technique or activity with another. Redesign strategies require solutions and institutional activities that mimic ecological processes. Solutions consistent with each category are analyzed and discussed in the areas of research, education, technology transfer, government programs and regulations, taxation, safety nets, consumer activism, marketing and advertising, corporate legal status, and organizational design and management.

Resumen

Scientific research, technological development, and commercialisation are processes through which new technologies continually emerge and enter markets. Nanotechnology is an example of an emergent technology (or rather a suite of technologies) which promises to open up a universe of possibilities for the development of new products and processes. Advocates of the technology argue that nanotechnology has the potential to spur economic development while at the same time offering partial solutions to many of the grand challenges of our times such as alleviating hunger, providing new energy sources, reducing climate change, curing diseases, etc. However, alongside these optimistic views, there are also fears and apprehensions concerning the safe and ethical development of nanotechnologies, including the need to address potential negative impacts on the natural environment and human health and safety. The food and food packaging area has shown itself to be a particularly sensitive sector in this respect where the potential for nanoparticles to enter the human body has enhanced the sensitivity of the industry to public concern. The past has shown that any changes or modifications made to food have resulted in public backlash (e.g. GM foods). Due to this some parts of the food and packaging industry remain cautious about making transparent their use of nanotechnologies in their products and processes. However, simultaneously pressure is mounting from regulatory agencies, and from some activists, to pursue the safe and 'responsible' development of nanotechnologies (whatever that may be) as an ethical obligation. The use of nanotechnologies in food and food packaging has become increasingly complex because of its introduction at various points in the food chain, giving rise to debates as to "who is responsible". As a contribution to the debate on what constitutes the 'responsible' governance of new/emergent technologies, this thesis investigates the governance of nanotechnologies and the idea of 'responsibility' and 'responsible innovation' through the lens of perspectives of different actors within the nanotech food chain. A qualitative research methodology was used where semi-structured interviews were conducted with a heterogeneous group of actors with a particular focus on the food and food packaging sectors. Research in comparative national settings (Canada and India) was conducted on the grounds that regulation of nanotechnologies differs significantly across OECD and non-OECD countries, and where the global debate on nanotechnologies is organised and dominated by OECD countries. Findings from this thesis showed that the set of critical elements, such as health and safety, that are put forward by such OECD countries like Canada for the 'responsible' development of nanotechnologies are not the same as that found in India and are seen to differ. In India, meeting the grand challenges of society such as food security, clean drinking water and alleviating poverty take precedent over other elements, where science, technology (such as nanotechnologies) and innovation are harnessed by entrepreneurs, and small and large firms to solve these national problems. However, while I began the study with the intention of comparing two national territories with different regulatory settings, the study also found a case of collaborative Canada-India transnational research network where 'responsibility' is influenced through certain funding criteria set by the more dominant partner, Canada. This suggests the return of public intervention by dominant OECD countries in pro-actively shaping R&D processes that are influencing the 'responsible' development of nano-products in such emerging markets, where there is a potential for future trade associations.

Resumen

L’objectif principal de cette thèse est la caractérisation et l’analyse des transformations du système alimentaire des Inuit du Nunavik, et en particulier les enjeux soulevés à l’intersection des interactions humains-milieux, puis les conséquences encourues pour le bien-être et la santé des Inuit. Des pistes de solution pour améliorer la résilience du système alimentaire dans cette région nordique y sont explorées, dont la principale est le développement de projets de jardinage communautaire. La collecte des données pour réaliser les quatre articles qui forment le corps de cette thèse s’est échelonnée entre octobre 2015 et mars 2019 dans les villages nordiques de Kuujjuaq et Kangiqsujuaq, au Nunavik. Différentes méthodes ont été combinées, dont la principale se base sur les principes de la recherche-action participative. Les résultats illustrent que les aliments traditionnels issus des activités de chasse, de pêche et de cueillette demeurent des vecteurs importants de la relation au territoire et du bien-être inuit, malgré le fait qu’ils ne représentent plus qu’une fraction de la diète. La perte de mobilité et l’adoption d’un nouveau mode de vie, accompagnées et rendues possibles par la transition nutritionnelle, ont perturbé les interactions humains-milieux à différents niveaux. La plus grande pression exercée sur l'environnement naturel provient des activités humaines menées ailleurs sur la planète et d’un modèle de consommation incompatible qui génèrent de nombreuses externalités négatives sur l’environnement et la santé humaine. À travers leur alimentation, les Inuit du Nunavik sont dorénavant connectés au reste du monde par le biais du système alimentaire globalisé, dont les ramifications complexes couvrent toute la planète Or, au Nunavik, les défauts inhérents à la chaîne de production agroalimentaire globalisée s’expriment d’une façon bien singulière. L’intensification des liens entre économie inuit et économie globalisée concourt à placer les territoires nordiques dans une position d’échange inégal et de dépendance envers les producteurs et les fournisseurs d’un secteur agroalimentaire exogène au sein duquel les résidents du Nord ont peu d’occasions de se faire entendre. La souveraineté alimentaire à l’égard des aliments du marché est ainsi fortement limitée
The main objective of this thesis is the characterization and analysis of the transformations of the Nunavik Inuit food system, and particularly the issues raised at the intersection of human-environment interactions and their consequences for Inuit health and well-being. Possible solutions to improve the resilience of the food system in this northern region are explored, the main one being the development of community gardening projects. The collection of data to complete the four articles that make up the body of this thesis took place between October 2015 and March 2019 in the northern villages of Kuujjuaq and Kangiqsujuaq, Nunavik. This research combines different methods, the main one being based on the principles of participatory action research. The results illustrate that traditional foods from hunting, fishing and gathering activities continue to be important drivers of Inuit’s well-being and relationship to the land, despite the fact that they are now consumed in smaller quantities. The loss of mobility and the adoption of a new way of life, accompanied and made possible by the nutritional transition, have disrupted human-environment interactions at different levels. The greatest pressure on the natural environment comes from human activities elsewhere in the world and from a pattern of inconsistent consumption that generates many negative externalities on the environment and human health. Through the food they eat, the Inuit are now connected to the rest of the world through the globalized food system, the complex ramifications of which cover the entire planet. In Nunavik, the defects inherent in the global agri-food production chain are expressed in a very singular way. The intensification of the links between the Inuit economy and the globalized economy contributes to placing the northern territories in a position of unequal exchange and dependence on the producers and suppliers of an exogenous agri-food sector in which northern residents have few opportunities to be heard. Food sovereignty over market foods is thus severely limited

Resumen

All branches of federal government are required to change their business practices to a paperless operation. Privacy and information security are critical for the protection of information shared over networks internally between the U.S. government agencies and externally with nonfederal organizations (businesses; state, local, and foreign governments; academia; etc.) or individuals. The public-key infrastructure (PKI) is the simplest, most widely used architecture for secure data exchange over unsecured networks. It integrates computer hardware and software, cryptography, information and network security, and policies and procedures to facilitate trust in distributed electronic transactions and mitigate the associated risks. Federal PKI (FPKI) is PKI designed for implementation and use by government agencies. Federal PKI research was under way since 1991, and by the end of 2005, the federal PKI included 13 cross-certified federal entities, three approved shared service providers (SSPs; Verisign, Cyber- Trust, National Finance Center/U.S. Department of Agriculture [USDA]), one state, and three foreign countries (Canada, UK, and Australia; Alterman, 2005). Initially envisioned as an interoperability mechanism for federal organizations exclusively, the federal PKI is now positioned for trust interoperability and cross-certification internally among federal agencies and externally with other organizations.

"Research Station at Cambridge and somewhat later at the Wantage Research Laboratories of the Atomic Energy Research Establishment. By the mid- or late 1950s national research programs on food irradiation were also underway in Belgium, Canada, France, The Netherlands, Poland, the Soviet Union, and the Federal Republic of Germany. This early history of food irradiation has been reviewed by Goldblith (9), Goresline (10), and Josephson (11). In 1960 the first books on food irradiation appeared, written by Desrosiers and Rosenstock in the United States (12) and Kuprianoff and Lang in Germany (13). A first international meeting devoted to discussion of wholesomeness and legisla tive aspects of food irradiation was held in Brussels in 1961 (14). In the United Kingdom the report of a government working party on irradiation of food (15) summarized and evaluated the studies done until 1964. The first commercial use of food irradiation occurred in 1957 in the Federal Republic of Germany, when a spice manufacturer in Stuttgart began to improve the hygienic quality of his products by irradiating them with electrons using a Van de Graaff generator (16). The machine had to be dismantled in 1959 when a new food law prohibited the treatment of foods with ionizing radiation, and the company turned to fumigation with ethylene oxide instead. In Canada irradiation of potatoes for inhibition of sprouting was allowed in 1960 and a private company, Newfield Products Ltd., began irradiating potatoes at Mont St. Hilaire, near Montreal, in September 1965. The plant used a 60Co source and was designed to process some 15,000 t of potatoes a month. It closed after only one season, when the company ran into financial difficulties (17). In spite of these setbacks, interest in food irradiation grew worldwide. At the first International Symposium of Food Irradiation, held in Karlsruhe, Germany, and organized by the International Atomic Energy Agency (IAEA), representa tives from 28 countries reviewed the progress made in research laboratories (18). However, health authorities in these countries still hesitated to grant permissions for marketing irradiated foods. At that time only three countries— Canada, the United States, and the Soviet Union— had given clearance for human consump tion of a total of five irradiated foods, all treated with low radiation doses. The food industry had not yet made use of the permissions. Irradiated foods were still not marketed anywhere. Questions about the safety for human consumption of irradiated foods were still hotly debated and this was recognized as the major obstacle to commercial utilization of the new process. As a result of this recognition the International Project in the Field of Food Irradiation (IFIP) was created in 1970, with the specific aim of sponsoring a worldwide research program on the wholesomeness of irradiated foods. Under the sponsorship of the IAEA in Vienna, the Food and Agriculture Organization (FAO) in Rome, and the Organization for Economic Cooperation and Development (OECD) in Paris, 19 countries joined their re sources, with this number later growing to 24 (see Table 1).

Resumen

The article offers an analysis of the development of the tractor and combine harvester fleet in 2001 - 2016. There are stated tractors and combines of the most common brands registered in the country. A methodology has been developed for the estimation of an adequate quantity of tractors and combines for timely cultivation of the sowing areas under agricultural crops. The methodology is based on the calculation of the annual increase in the summary engine capacity of the entire fleet of tractors and combine harvesters, and its comparison with the annual increase in the sowing areas. It is assumed that 10% of the sowing areas are cultivated by worn-out tractors, and 7.5% of the new tractor and combine capacity is required for the replacement (amortisation) of the worn-out tractors. We consider that the increase in the summary capacity should compensate for the increase in the sowing areas, taking into account also the impact of the total yield upon the productivity of the machinery. It has been found out that during the period the summary engine capacity of the tractors has grown 1.52 times, the summary engine capacity of the combine harvesters – 2.8 times; in the same period the area under agricultural crops has increased approximately 1.38 times but the area under cereals and canola – approximately 1.8 times. Several authors consider specific capacity kWh-1 as a criterion for the estimation of an adequate quantity of the machinery; therefore there are calculated also its changes in a 16-year period, with the specific capacity of both the tractors and combine harvesters increasing. The average specific power kWh-1 is considered as relatively high, but, due to the concentration of production, a decrease in this indicator is possible in the future. The average weighted capacity of the purchased new tractors and combine harvesters has also increased. The increase in the summary capacity of the tractor fleet compensates for the increase in the sowing areas and even exceeds it a little. In its turn, the increase in the summary capacity of the combine fleet allows timely harvesting the significantly increased sowing area, and more than twice the increased totals yield at the end of the period, and, compared to the beginning, slightly shorten the harvesting duration. The calculations do not include weather conditions during the harvesting period. As increase in the sowing areas and total yield is expected still further, upgrading of the tractor fleet should be continued at approximately the same rate – by purchasing, on the average, 600 to 700 new tractors and 80 to 100 new combine harvesters every year.

Resumen

Through the use of nonlinear finite element analysis (NLFEA), submarine pressure hull designs could potentially be based on calculated limit states that include the full geometric complexity of the structure, and real-world effects such as build imperfections. In addition, NLFEA could provide a rational means of assessing the effects of in-service damage on structural performance. Analysis of pressure hulls using 3D NLFEA is not currently supported in design codes, primarily because the uncertainty regarding the accuracy of the method has not been quantified. Defence Research and Development Canada (DRDC), the R&D branch of the Canadian Navy, is undertaking work to develop a partial safety factor for 3D NLFEA of pressure hulls, by comparison of numerically calculated collapse pressures to experimental results. Data from experiments previously conducted at various institutions will be augmented by a pressure hull testing program currently being undertaken by a joint project of DRDC and the Ministry of Defence of the Netherlands. The development of NLFEA modeling and analysis guidelines, as well as a revised design/analysis procedure, will be discussed, as well as a history of the DRDC submarine structures research program.

Resumen

This essay aims to analyse the impact of the 2020 global pandemic on the stock indexes of France (CAC 40), Germany (DAX 30), USA (DOW JONES), United Kingdom (FTSE 100), Italy (FTSE MID), Japan (Nikkei 225) and Canada (TSX 300), from January 2018 to June 2020, with the sample being divided into two sub periods: first sub period from January 2018 to August 2019 (Pre-Covid); second period from September 2019 to June 2020 (Covid-19). In order to carry out this analysis, different approaches were taken in order to analyse whether: (i) the global pandemic (Covid-19) increased the persistence of the G7 financial markets? In the Pre-Covid period, we can verify the presence of long memories in the Canadian market (TSX), while the markets in France (CAC 40) and Italy (FTSE MID) show signs of balance, since the random walk hypothesis was not rejected. The German (DAX 30), USA (DJI), United Kingdom (FTSE 100) and Japan (NIKKEI 225) markets have anti-persistence (0 <α <0.5). In period II, the Covid-19-time scale is contained, and we verified the presence of significant long memories, except for the US stock index (0.49). These findings make it possible to show that the assumption of the market efficiency hypothesis may be called into question, because these markets are predictable, which validate the research question. The results of the pDCCA correlation coefficients, in the Pre-Covid period, show 14 pairs of median markets (0.333 → ≌ 0.666). We can also see 7 pairs of markets with strong correlation coefficients (0.666 → ≌ 1,000), showing that these markets have a tendency towards integration, this evidence may call into question the hypothesis of portfolio diversification. In period II (Covid-19) the λ_DCCA correlation coefficients have 7 strong market pairs (0.666 → ≌ 1,000), 5 pairs have weak pDCCA coefficient (0.000 → ≌ 0.333), 5 market pairs show anti-correlation (-1.000 → ≌ 0.000), and 4 market pairs show median coefficients (pDCCA) (0.333 → ≌ 0.666) (out of 21 possible). When compared to the previous subperiod, we found that the majority of the pDCCAs decreased, which shows that the markets have decreased their integration, making it possible to diversify portfolios in certain markets, especially in the Japanese market (NIKKEI 225). These conclusions open space for market regulators to take measures to ensure better informational information, in the stock markets, in the 7 most advanced economies in the world.

Resumen

The current trends in the development of innovative activities in Russia are far from fully meeting the expectations associated with improving the competitiveness of products and the quality of life of the population, with the provision of dynamic sustainable growth, and the formation of the innovative economy. The mixed nature of the Russian economy, the fundamentally different technological level and institutional conditions for the development of various sectors exclude the possibility of defining a single model of innovative development that is universal for all sectors. In the current conditions, the technical and technological level of the agrarian sector of the country's economy is the most catastrophically lagging behind the world's leading producers of agricultural products. Domestic agrarian production is 5 times more energy intensive and 4 times more metal consuming, and labor productivity is 8-10 times lower than in the USA, in the leading countries of the European Union and Canada. Not having eliminated this techno-technological backlog, without implementing the advanced development of certain specific areas of scientific research and technological developments in the field of agriculture, Russia's agrarian sector will finally lose its competitiveness and will not be able to ensure the country's food security. Thus, the need for a scientific justification of the theory, methodology and practice of the innovative development management of the agrarian sector of the regional economy in the context of large-scale economic and institutional transformations determines the urgency of the issue. Currently, most of the works of domestic researchers put emphasis on the problems of knowledge transfer, at the same time, the methodology for creating and commercializing competitive scientific knowledge through the formation of innovative agricultural clusters is beyond the scope of scientific research, and its management and economic mechanism has not been developed yet. Thus, the aim of this research is to develop proposals for optimization of the management mechanism for the innovative development of the region's agricultural sector (by the example of the Samara Region of the Russian Federation). The research used a set of methods of scientific knowledge used at both theoretical and empirical levels (conceptual modeling, synthesis and analysis, tabular and graphical interpretation of theoretical information and empirical data).
