Specific Objects
No full textThe research explores Donald Judd's concept of Specific Objects, and how the notion of singular
qualities, so essential to the concept, can be extended through the practice of sculpture. According
to Judd, unity can only be achieved in sculpture when its form is specific and has only one quality.
There must therefore be no apparent parts, no hierarchy and, therefore no relationships of parts. In
addition, Specific Objects rejects illusion. The sculptor Robert Morris further defined singular
qualities as those which predominantly distinguish 'good form', thereby positioning it within the
syntax of Gestalt psychology. Significant though Judd's sculptures are, few seem to conform to his
definition of Specific Objects because through his use of orthogonal geometry and contrast of
materials, many of his sculptures do indeed appear not only to be composed of parts, but actually
rely on the relationships between the parts. In addition, the contrast of opaque and transparent
surfaces, inevitably leads to illusion. Rather than follow Judd's use of orthogonal geometries from
parts of differing materials and colours, this research has investigated the potential of circular
geometry to create form of sculptural significance within Judd's strict definition of Specific Objects.
Key to this research has been what Rosalind Krauss described as the deflection of geometry, of
which there are two types: one is based on actual variations in physical geometry and the second
results from the illusory qualities of materials and surface finishes.
The studio investigations sought to ascertain to what extent the 'deflection of geometry'can
expand, but equally as importantly, maintain the viability of Judd's concept. In other words, the
challenge was to extend the possible range of geometries that posses the singular qualities
associated with Specific Objects; and in so doing provide an alternative response to the dilemma
posed by the concept; how to make unified forms with variation and sculptural significance.
The studio investigations were project based. Each project was directed by its aims and the resulting
studies evaluated through criteria in which unity and singular qualities were fundamental. A reductive approach to studio investigation led to two forms that conclude the research. The unified
geometry of the first is elliptical, although visual tension derives from the rotation of the internal
ellipse relative to its external counterpart, whereas the second form contains the implied division of
an internal figure of eight derivative within an elliptical exterior. Both forms were cast in
translucent resins to combine illusory and physical deflections of their geometry. By so doing, they
expand Judd's concept, by demonstrating the potential for implied duality and perceived variance to
exist within a singular, unified, and specific form
Bounded orbits of diagonalizable flows on finite volume quotients of products of SL 2 ( R )
No full textWe prove a number field analogue of W. M. Schmidt's conjecture on the intersection of weighted badly approximable vectors and use this to prove an instance of a conjecture of An, Guan and Kleinbock. Namely, let G := SL_2(\mathbb{R}) \times \dots \times SL_2(\mathbb{R}) and \Gamma be a lattice in G. We show that the set of points on G/\Gamma whose forward orbits under a one parameter Ad-semisimple subsemigroup of G are bounded, form a hyperplane absolute winning set
Repeated-Batch Fermentation of Cheese Whey for Semi-Continuous Lactic Acid Production Using Mixed Cultures at Uncontrolled pH
No full textThe paper investigates mixed-culture lactate (LA) fermentation of cheese whey (CW) in order to verify the possibility of using waste materials as feedstock to produce a product with high economic potential. The fermentation performance of two reactors operating in repeated-batch mode under uncontrolled pH conditions and various hydraulic retention time and feeding conditions was evaluated in terms of LA production. Five experimental phases were conducted. The hydraulic retention time (HRT) was varied from 1 to 4 days to verify its effect on the process performance. The best results, corresponding to the maximum LA concentration (20.1 g LA/L) and the maximum LA yield (0.37 g chemical oxygen demand (COD)(LA)/g COD(CW)), were reached by feeding the reactors with cheese whey alone and setting the HRT to 2 days. The maximum productivity of lactic acid (10.6 g LA/L/day) was observed when the HRT was decreased to 1 day

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Detectors and Correctors: A Theory of Fault-Tolerance Components
No full textIn this paper, we show that two types of tolerance components, namely detectors and correctors, appear in a rich class of fault-tolerant systems. This class includes systems designed using the wellknown techniques of encapsulation and refinement, as well as systems designed using extant fault-tolerance methods such as replication and the state-machine approach. Our demonstration is via a theory of detectors and correctors, which characterizes the particular role of these components in achieving various types of fault-tolerance. Based on this theory and on our experience with using these components in designs, we suggest that detectors and correctors provide a powerful basis for efficient, component-based design of fault-tolerance. Keywords : Composition, Fault environment, Tolerance components, Tolerance design 1 A preliminary version of this paper appeared as [6].

The Right to Strike under the United States Constitution: Theory, Practice, and Possible Implications for Canada
No full textAnswering critics of the Canadian Supreme Court's judgment in B.C. Health, the author argues that the Court laid the foundation for a principled and durable doctrine protecting constitutional labour rights, one that goes directly to the heart of the matter — the inequality of workers’ power in the employment relation. In the author’s view, two paths could lead from B.C. Health to the recognition of Charter protec- tion for a right to strike: one that treats the right as an accessory to col- lective bargaining, and one that upholds the right directly on the basis of the Charter values of equality and participation. The author supports the latter approach, contending that constitutional rights should be defined in relation to fundamental values, in a way that is not contingent on time-bound or fact-sensitive assessments about the role of strikes within a particular collective bargaining regime. Although a Charter right to strike may involve the courts in difficult choices about when to defer to legislative policy decisions, and courts may lack the institutional capac- ity to deal effectively with labour law issues, the author points out that judges can look to ILO standards for expert guidance. Noting that the U.S. experience in this area might be of considerable use to Canadians, the author concludes by providing an overview of American case law concerning a constitutional right to strike.Peer reviewe
