Financing activities of provincial governments and their enterprises

This article examines the changes that have occurred in the composition of funds raised by provincial borrowers during the 1990s. Higher financing requirements, coupled with the declining availability of funds from non-market sources such as the Canada Pension Plan, led provincial governments and their Crown corporations to broaden and to diversify their debt management programs. In particular, provincial borrowers expanded their presence in foreign bond markets, increased their issuance of floating-rate debt, and incorporated a wide variety of innovative debt instruments into their borrowing programs in order to minimize their borrowing costs and to manage the risks associated with the issuing of debt. As a result, the composition of funds raised by provincial borrowers during the 1990s differed markedly from that of the previous decade: between 1990 and 1995, provincial borrowing requirements were met almost entirely through the issuance of marketable debt, and net new foreign currency debt issues averaged nearly 50 per cent of funds raised, whereas between 1980 and 1989, non-market sources provided close to 30 per cent of funds raised, and net new foreign currency debt issues provided less than 20 per cent.

3D Sand Printing for Automotive Mass Production Applications

Additive manufacturing (AM) of metallic products is seen by many to be commercially viable for only small and highly complex components, manufactured with difficult to machine materials using heat sintering process. In the automotive manufacturing sector, metal hard tooling is often required to produce mass produced components, and the tools are typically bespoke, large in size, inflexible and complex. Conventionally these tools have either been machined from solid billets or near-net-shape cast and then machined to achieve final size. Rapid casting technologies (RCT) use AM 3D sand printing process to manufacture sand mould tools used to create the production tooling. Adopters of this technology can achieve an increasingly agile and robust production process, RCT can also rewrite the design hand book for casting design. The research findings demonstrate that RCT can be successfully applied within the automotive industry, achieving considerable cost and time savings whilst improving quality and product flexibility

The fiscal impact of privatization in Canada

Privatization -- the transfer of activities from the public to the private sector -- gained international prominence in the 1980s because of the need to reduce budget deficits and growing concerns about the efficiency of state-owned enterprises and government bureaucracies. This article examines privatization in Canada and its effect on governments' fiscal positions. Privatization has generally been less rapid and extensive in Canada than elsewhere, partly because of the comparatively moderate size of our public sector. Nevertheless, federal, provincial, and municipal governments have increasingly reduced their direct involvement in the Canadian economy by selling Crown corporations, contracting with private firms to deliver public services, and transferring the development of public infrastructure projects to the private sector. The fiscal impact of privatizing Crown corporations varies with such factors as the profitability of the enterprise, the size of the government's initial investment, and past write-downs. In general, when privatizations are part of a broader effort to improve public finances, they can contribute to fiscal consolidation by reducing budgetary requirements and debt levels. When services and infrastructure projects are privatized, it is expected that more efficient private sector management will reduce government expenditures. For example, a private consortium may be better able to manage the financial risks involved in building an infrastructure facility, such as cost overruns or the withdrawal of contractors, than the public sector. The key to raising efficiency and lowering costs, however, is competition, not privatization per se. Therefore, the cost savings arising from the privatization of services or public works depend crucially on the terms of the contract. Overall, when structured to improve economic efficiency, privatization is likely to enhance the economy's performance, thereby producing long-term economic and budgetary gains.

Draft genome sequences of the type strains of Shigella flexneri held at Public Health England: comparison of classical phenotypic and novel molecular assays with whole genome sequence.

BACKGROUND: Public Health England (PHE) holds a collection of Shigella flexneri Type strains isolated between 1949 and 1972 representing 15 established serotypes and one provisional type, E1037. In this study, the genomes of all 16 PHE Type strains were sequenced using the Illumina HiSeq platform. The relationship between core genome phylogeny and serotype was examined. RESULTS: The most common target gene for the detection of Shigella species in clinical PCR assays, ipaH, was detected in all genomes. The type-specific target genes were correctly identified in each genome sequence. In contrast to the S. flexneri in serotype 5 strain described by Sun et al. (2012), the two PHE serotype 5 Type strains possessed an additional oac gene and were differentiated by the presence (serotype 5b) or absence (serotype 5a) of gtrX. The somatic antigen structure and phylogenetic relationship were broadly congruent for strains expressing serotype specific antigens III, IV and V, but not for those expressing I and II. The whole genome phylogenies of the 15 isolates sequenced showed that the serotype 6 Type Strain was phylogenetically distinct from the other S. flexneri serotypes sequenced. The provisional serotype E1037 fell within the serotype 4 clade, being most closely related to the Serotype 4a Type Strain. CONCLUSIONS: The S. flexneri genome sequences were used to evaluate phylogenetic relationships between Type strains and validate genotypic and phenotypic assays. The analysis confirmed that the PHE S. flexneri Type strains are phenotypically and genotypically distinct. Novel variants will continue to be added to this archive

The lifetime of nitrogen oxides in an isoprene-dominated forest

The lifetime of nitrogen oxides (NO_x) affects the concentration and distribution of NO_x and the spatial patterns of nitrogen deposition. Despite its importance, the lifetime of NO_x is poorly constrained in rural and remote continental regions. We use measurements from a site in central Alabama during the Southern Oxidant and Aerosol Study (SOAS) in summer 2013 to provide new insights into the chemistry of NO_x and NO_x reservoirs. We find that the lifetime of NO_x during the daytime is controlled primarily by the production and loss of alkyl and multifunctional nitrates (ΣANs). During SOAS, ΣAN production was rapid, averaging 90 ppt h^(−1) during the day, and occurred predominantly during isoprene oxidation. Analysis of the ΣAN and HNO_3 budgets indicate that ΣANs have an average lifetime of under 2 h, and that approximately 45 % of the ΣANs produced at this site are rapidly hydrolyzed to produce nitric acid. We find that ΣAN hydrolysis is the largest source of HNO_3 and the primary pathway to permanent removal of NO_x from the boundary layer in this location. Using these new constraints on the fate of ΣANs, we find that the NO_x lifetime is 11 ± 5 h under typical midday conditions. The lifetime is extended by storage of NO_x in temporary reservoirs, including acyl peroxy nitrates and ΣANs

Does discussion lead to opinion change within Political Science students? A pedagogical exercise of deliberative democracy

While the model of deliberative democracy gives a crucial role to dialog, empirical evidence has not yet established if discussion helps to reach a better understanding of political issues and, above all, if individuals are prepared to change their views. It is still unclear when the deliberative model, and more specifically discussion, could be usefully employed as a teaching tool, to improve students’ knowledge. This article presents an exercise performed within the Department of Political and Social Sciences at the LUISS University of Rome. Students were asked to discuss in the classroom the issues related to the course, and to cast a vote on selected issues before and after deliberation. Although our sample is not representative, we have gathered evidence from the same population on a rather large number of issues. Students changed their view in 24.6% of cases, and they agreed that discussion increased their understanding, while those with strong ex-ante views resulted more reluctant to change their opinions because of discussion. The analysis also showed the presence of individuals that are more likely to be permeable to discussion while others that are more likely to be impermeable

An evaluation and monetary assessment of the impact of flooding on subjective well-being across genders in Vietnam

The intangible impacts of floods on welfare are not well investigated, even though they are important aspects of welfare. Moreover, flooding has gender based impacts on welfare. These differing impacts create a gender based flood risk resilience gap. We study the intangible impacts of flood risk on the subjective well-being of residents in central Vietnam. The measurement of intangible impacts through subjective well-being is a growing field within flood risk research. We find an initial drop in welfare through subjective well-being across genders when a flood is experienced. Male respondents tended to recover their welfare losses by around 80% within 5 years while female respondents were associated with a welfare recovery of around 70%. A monetization of the impacts floods have on an individual’s subjective well-being shows that for the average female respondent, between 41% to 86% of annual income would be required to compensate subjective well-being losses after 5 years of experiencing a flood. The corresponding value for males is 30% to 57% of annual income. This shows that the intangible impacts of flood risk are important (across genders) and need to be integrated into flood (or climate) risk assessments to develop more socially appropriate risk management strategies

Development of a candidate reference material for adventitious virus detection in vaccine and biologicals manufacturing by deep sequencing.

Unbiased deep sequencing offers the potential for improved adventitious virus screening in vaccines and biotherapeutics. Successful implementation of such assays will require appropriate control materials to confirm assay performance and sensitivity. A common reference material containing 25 target viruses was produced and 16 laboratories were invited to process it using their preferred adventitious virus detection assay. Fifteen laboratories returned results, obtained using a wide range of wet-lab and informatics methods. Six of 25 target viruses were detected by all laboratories, with the remaining viruses detected by 4-14 laboratories. Six non-target viruses were detected by three or more laboratories. The study demonstrated that a wide range of methods are currently used for adventitious virus detection screening in biological products by deep sequencing and that they can yield significantly different results. This underscores the need for common reference materials to ensure satisfactory assay performance and enable comparisons between laboratories
