Revisiting the Coyne Affair: A Singular Event That Changed the Course of Canadian Monetary History
No full textThe Coyne affair is the greatest institutional crisis faced by the Bank of Canada in its history. The crisis took place in 1959-1961 and led to the resignation of the Governor, once he was cleared of any wrongdoing. The crisis eventually resulted in a major reform of the Bank of Canada. The paper highlights the critical role played by the directive in central banking legislation. Archival and empirical evidence is used to assess the performance of monetary policy throughout the 1950s. In doing so, a real-time dataset is constructed for both Canada and the US that permits estimation of reaction functions. I find that the case against James Coyne is \'not proven\'.Coyne Affair; monetary policy stance; Taylor rules; real-time data
Designing Information Technology in the Postmodern Age
No full textDesigning Information Technology in the Postmodern Age puts the theoretical discussion of computer systems and information technology on a new footing. Shifting the discourse from its usual rationalistic framework, Richard Coyne shows how the conception, development, and application of computer systems is challenged and enhanced by postmodern philosophical thought. He places particular emphasis on the theory of metaphor, showing how it has more to offer than notions of method and models appropriated from science. Coyne examines the entire range of contemporary philosophical thinking -- including logical positivism, analytic philosophy, pragmatism, phenomenology, critical theory, hermeneutics, and deconstruction -- comparing them and showing how they differ in their consequences for design and development issues in electronic communications, computer representation, virtual reality, artificial intelligence, and multimedia. He also probes the claims made of information technology, including its presumptions of control, its so-called radicality, even its ability to make virtual worlds, and shows that many of these claims are poorly founded. Among the writings Coyne visits are works by Heidegger, Adorno, Benjamin, Gadamer, Derrida, Habermas, Rorty, and Foucault. He relates their views to information technology designers and critics such as Herbert Simon, Alan Kay, Terry Winograd, Hubert Dreyfus, and Joseph Weizenbaum. In particular, Coyne draws extensively from the writing of Martin Heidegger, who has presented one of the most radical critiques of technology to date
The Persistence of the R.A. Fisher-Sewall Wright Controversy
No full textThis paper considers recent heated debates led by Jerry A. Coyne and Michael J. Wade on issues stemming from the 1929-1962 R. A. Fisher-Sewall Wright controversy in population genetics. William B. Provine once remarked that the Fisher-Wright controversy is central, fundamental, and very influential. Indeed, it is also persistent. The argumentative structure of the recent (1997-2000) debates is analyzed with the aim of eliminating a logical conflict in them, viz., that the two “sides” in the debates have different aims and that, as such, they are talking past each other. Given a philosophical analysis of the argumentative structure of the debates, suggestions supportive of Wade’s work on the debate are made that are aimed, modestly, at putting the persistent Fisher-Wright controversy on the course to resolution
Cornucopia Limited: Design and Dissent on the Internet
No full textThe Internet provides a remarkable demonstration of the persistence of the gift in contemporary commerce. Net enthusiasts seem prepared to donate much to the common good. This generous spirit ought to strike resonances with the culture of design, which generally promotes a creative ethos of generosity, conspicuous display, and exuberance. But the cornucopia of the gift economy is offset by net culture's recent leanings towards consumerism. This book challenges the supposed gift society of the Internet, and supplants the gift by a more compelling metaphor, enjoyed in certain quarters of contemporary design, that of theft, rule breaking, and transgression. The relationship between design thinking and the network economy is characterized by the reckless spirit of the trickster, the crosser of boundaries, and the malingerer in the hybrid and uncertain condition of the threshold. The book thus presents a designer's view of the network economy, drawing on insights from design theorists, economists, philosophers and cultural theorists. It provides valuable insights for theorists of human-computer interaction, architects, designers, and those interested in registering the source and direction of the impulse to create, innovate, and design. The book examines five metaphors: household, machine, game, gift and threshold. Economic theory is grounded in the household. The romantics and Marx claimed that labor is dominated by the rampant machinery of capitalism. The computer game represents a potent exemplar of new media economics. The gift is presented as precursor to commercial exchange. Coyne subjects each metaphor to scrutiny in terms of how it deals with the threshold, in other words as it is dissected by the cynic or manipulated by the trickster, and other liminal dwellers in the network economy.'What's shaping the culture of the Internet? This turns out to be a surprisingly tricky question, one that Richard Coyne explores with verve and erudition.'--Albert Borgmann, author of Holding On to Realit
Investigation of the role of the extracellular β-agarase, produced by the bacterial epiphyte Pseudoalteromonas sp. LS2i, in the virulence response towards the agarophyte Gracilaria gracilis
No full textIncludes abstractIncludes bibliographical referencesGracilaria gracilis that grows naturally at Saldanha Bay, South Africa is economically important as a source of agar. The Gracilaria yields from natural beds at Saldanha Bay are however unreliable, and consequently the South African Gracilaria industry has experienced a number of setbacks over the years. The only way a consistent supply can be assured is by mariculture to supplement the natural harvests. In 1993 the Seaweed Research Institute (SRU) found that mariculture of G. gracilis in Saldanha Bay is feasible but that there is potential to improve yields by technical research and development (Anderson et al.1996a). Jaffray and Coyne (1996) developed a pathogenicity assay that demonstrated that agarolytic bacteria isolated from Saldanha Bay Gracilaria induced disease symptoms such as thallus bleaching, while non-agarolytic isolates did not. It is thought that unfavorable environmental conditions such as elevated water temperature and nutrient depletion, which occur during the summer months in the surface layers of the water column in Saldanha Bay, induce the onset of agarase production or result in changes in the bacterial community structure in which agarase-producers become more dominant. By using the pathogenicity assay, Jaffray and Coyne (1996) identified the highly agarolytic Gracilaria gracilis pathogen, Pseudoalteromonas sp. LS2i. The aim of this study was to characterize the bacterial pathogen, Pseudoalteromonas sp. LS2i to further our understanding of virulence regulation and specifically, the role of the agarase enzymes in the process of seaweed-pathogen interaction. Two agarolytic clones, pEB1 and pJB1, were obtained after constructing and screening a Pseudoalteromonas sp. LS2i genomic library in Esherichia coli. Restriction enzyme mapping suggested that both clones contain the same agarase gene. Southern hybridization studies confirmed the origin of the cloned DNA and sequencing studies revealed the 1062 bp ORF, putative promoter region, putative ribosome binding site and putative transcriptional start point of the cloned agarase gene. The ORF showed sequence identity to several other β-agarases and was identified as a member of the GH-16 family of glycoside hydrolases. The agarase was purified from the E. coli JM109 (pEB3) transformant. The molecular weight was estimated to be 39 kDa by SDS-PAGE. Zymogram analysis confirmed that the purified protein is agarolytic and TLC analysis revealed that the predominant end-products of agar hydrolysis are neoagarohexaose and neoagarobiose, which indicates the same mode of action as that observed for the agarase produced extracellularly by Pseudoalteromonas sp. LS2i
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
Registration of Great Northern Common Bean Cultivar ‘Coyne’ with Enhanced Disease Resistance to Common Bacterial Blight and Bean Rust
No full textGreat northern common bean (Phaseolus vulgaris L.) ‘Coyne’ (Reg. No. CV-287, PI 655574) was developed by the dry bean breeding program at the University of Nebraska Agricultural Research Division and released in 2008. It was bred specifically for adaptation to Nebraska growing conditions and for enhanced resistance to common bacterial blight (CBB), a major disease of common bean caused by the seed-borne bacterium Xanthomonas campestris pv. phaseoli (Smith) Dye, and bean common rust Uromyces appendiculatus (Pers.:Pers) Unger. Coyne is a great northern F7:8 line derived from a three-way cross (G95023/Weihing//BelMiNeb-RMR-11). The first cross was made in winter 2003. The F7:8 was tested in advanced yield trials at Scottsbluff and Mitchell, NE, and in growers’ fields in Nebraska. Yield of Coyne was only 47 kg ha–1 lower than ‘Marquis’ in Morrill and Scotts Bluff, NE, counties. Reaction of Coyne to CBB under field conditions was consistent across 3 yr at the West Central Research and Extension Center, North Platte, NE, where fi eld disease ratings of 3.2, 3.5, and 4.4 were recorded in 2005, 2006, and 2007, respectively. Coyne has the Ur-3 and Ur-6 genes for resistance to common bean rust and carries the single dominant hypersensitive I gene that provides resistance to all non-necrotic strains of Bean common mosaic virus. Coyne has bright white seed, blooms 44 d after planting, and is a midseason bean, maturing 91 d after planting

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
