"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.
Monoposto racecar wheel aerodynamics: investigation of near-wake structure and support-sting interference
No full textMonoposto racecar development is routinely carried out using wheels supported not by the car
suspension but by individual, externally-mounted stings. The interference effect of these stings
was acknowledged but unquantified in the existing literature. Appraisal of the literature has
found that the structure of a wheel wake was not understood, rendering it difficult to assess the
support sting interference. These two issues were thus jointly addressed using experimental and
computational methods.
The two phases of this project each tested a different industrially-representative racecar wheel
model. Phase One investigated a single wheel and sting combination, whilst Phase Two extended
the work to include two further stings and a model racecar. Non-intrusive velocity measurements
were made in the near wakes of the various combinations to extract vertical planes, perpendicular
to the tunnel freestream.
The measurements made behind the isolated wheels were used to investigate the main flow
features of the wake. The flow surrounding an unsupported wheel was established computationally
and used to evaluate the interference effects of the support sting. Different wheel support
methods (three stings and the car suspension) were used to provide further insight into the sting
interference effects and also the impact of sting design on those effects. Testing with and without
the model racecar allowed evaluation of its effect on the wheel wake and sting interference.
The main characteristics of the near-wake of an isolated wheel rotating in ground contact are
proposed from analysis of the data generated in this study. A simplified model of the trailingvortex
system induced in the wake of such a wheel is proposed to clarify contradictory literature.
The specific interference effects of a wheel support sting are proposed with reference to the main
characteristics of the wake. The mechanisms behind these effects are, where possible, identified
and presented. The main impact of the support sting, and thus the root of several of the observed
effects, is the modification of the axial flow through the wheel.
The main effects of the presence of the car on the near-wake are proposed alongside the observation
that the wake structure is not fundamentally different to that of an isolated wheel. The
proposed sting interference effects are also observed in the presence of the car, albeit at a reduced
level
Macrophonics II
No full textMacrophonics II presents new Australian work emerging from the leading edge of performance interface research. The program addresses the emerging dialogue between traditional media and emerging digital media, as well as dialogues across a broad range of musical traditions. Recent technological developments are causing a complete reevaluation of the relationships between media and genres in art, and Macrophonics II presents a cross-section of responses to this situation. Works in the program foreground an approach to performance that integrates sensors with novel performance control devices, and/or examine how machines can be made musical in performance. The program presents works by Australian artists Donna Hewitt, Julian Knowles and Wade Marynowsky, with choreography by Avril Huddy and dance performance by Lizzie and Zaimon Vilmanis. From sensor-based microphones and guitars, through performance a/v, to post-rock dronescapes, movement inspired works and experimental electronica, Macrophonics II provides a broad and engaging survey of new performance approaches in mediatised environments.\ud

Initial R&D for the work was supported by a range of institutions internationally, including the Australia Council for the Arts, Arts Queensland, STEIM (Holland) and the Nes Artist Residency (Iceland)
The R&D Tax Incentives
No full textThis article sets out some background information and reflections of the author on the R&D tax incentive schemes included in the Common Corporate Tax Base (CCTB) Proposal. In particular the author analyzes the stimulus to private R&D through ad hoc tax incentives included in the CCTB Proposal and dives into the actual provisions included in the Proposal highlighting the most relevant issues connected with their design and interpretation. Moreover, the author explores the interaction between the CCTB Proposal and the granting by Member States of domestic R&D tax incentives
Using strategic ambiguity as management practice in academic R&D : An ethnographic study of MIT SENSEable City Lab
No full textThis article explores the role of strategic ambiguity (Eisenberg, 2007; March & Olsen, 1976) as a management practice, as used in SENSEable City Lab - a R&D-oriented lab located at the Massachusetts Institute of Technology in Cambridge, MA.
Although literature has already explored strategic ambiguity in various organizational settings, studies focusing on how academic institutions use strategic ambiguity in the context of R&D are quite sparse.
The article aims at filling this gap by reporting on a study conducted by the author across 2011 and 2014 in a R&D-oriented academic lab and reflecting on the potential of strategic ambiguity as an effective dialogic strategy to appreciate differences among internal organization members and with external partners. The article also examines some shortcomings of strategic ambiguity, such as the level of anxiety reported by some members of the lab
Preemptive Search and R&D Clustering Revisited
No full textThe results obtained by Cardon and Sasaki (1998) on R&D clustering are derived under the specific assumption that firms only can own one patent. When multiple patents are allowed, R&D clustering will come about more frequently if search costs are substantial.R&D clustering; persistence of monopoly
Measuring the Returns to R&D: The Depreciation Problem
No full textMeasuring the private returns to R&D requires knowledge of its private depreciation or obsolescence rate, which is inherently variable and responds to competitive pressure. Nevertheless, most of the previous literature has used a constant depreciation rate to construct R&D capital stocks and measure the returns to R&D, a rate usually equal to 15 per cent. In this paper I review the implications of this assumption for the measurement of returns using two different methodologies: one based on the production function and another that uses firm market value to infer returns. Under the assumption that firms choose their R&D investment optimally, that is, marginal expected benefit equals marginal cost, I show that both estimates of returns can be inverted to derive an implied depreciation rate for R&D capital. I then test these ideas on a large unbalanced panel of U.S. manufacturing firms for the years 1974 to 2003. The two methods do not agree, in that the production function approach suggests depreciation rates near zero (or even appreciation) whereas the market value approach implies depreciation rates ranging from 20 to 40 per cent, depending on the period. The concluding section discusses the possible reasons for this funding.
The Philippine Fisheries R&D Institutions: A Look at Their Publication Record
No full textOne of the indicators to measure the performance of fisheries R&D institutions is their ability to publish, especially in refereed journals in their area of specialization. This Policy Notes examines the publication record of fisheries R&D institutions in the Philippines and concludes that only a few have performed creditably over the years in this aspect. In view of this, the author recommends a number of specific actions to be taken by both the institutions concerned and the national government in order to improve the overall capacity of the fisheries R&D institutions to publish.fisheries R&D institutions, publication record
A study of the strategic environment of an R&D section within a larger organisation
No full textThis work addresses the problem of how an R&D section should decide on a strategy to guide its work when there is no strategic direction supplied from above by the company. The work includes a participant observer case study carried out over five years in a single R&D section, an analysis of research papers on the subject of management of section level R&D, and a review of textbooks on strategy, management and organisational behaviour.
From the case study it was concluded that the company itself formed the strategic environment which the strategy of the R&D section had to address, and that the section’s strategic environment was chaotic in the mathematical sense. From the review of management textbooks it was concluded that standard theories do not give usable guidelines for the manager in this situation. A theory was developed that R&D strategy can be thought about in four distinctly different ways. Publications concentrate on two of these, while the case study and surveys of practising managers revealed that the other two were more pertinent in practice.
The analysis of research papers was carried out using a newly developed technique, which showed that this body of literature is in a pre-paradigm state. The new technique was also used to show that the four different ways of thinking about R&D are present in the papers. The new literature analysis technique and the theory that R&D strategy can be thought about in four different way were tested by means of questionnaires filled in by authors of papers and by groups of R&D practitioners
