Technology strategy and innovation: the use of derivative strategies in the aerospace industry

Strategy has become an increasingly important theme within the management of innovation. This is reflected in the increasing amount of attention given to topics such as technology strategy within the innovation literature. However research into technology strategy has tended to focus on technology acquisition rather than technology exploitation. This paper focuses on one often neglected way in which companies can exploit the technological resources at their disposal, namely through the use of a derivative strategy where new technology is combined with old products or parts of old products in order to develop new products. The paper explores this type of strategy by means of a case study from the commercial jet engine sector of the aerospace industry. The case study provides an opportunity not only to explore the nature of derivative strategies in detail it also highlights the benefits, both direct and indirect, to be gained from this type of strategy as a means of exploiting an organisation's technological resources. The paper shows how a derivative strategy can contribute to the broader strategic goals of companies in technology based industries through strategies designed to ensure the most effective utilisation of the technology base

An Examination Of Accounting Majors\u27 Ethical Decisions Before And After An Ethics Course Requirement

The increased focus on ethical decision making in the accounting profession has resulted in greater attention being paid to the education of future accountants. Texas is one of the states that requires a State Board approved university course in Accounting Ethics to be on the transcript of prospective CPA candidates. This study reports on research using senior/graduate level accounting majors at a Texas state university before the university course requirement and after the requirement. The survey presented four vignettes for the students to consider (i.e., 2 describe an ethical decision and 2 describe an unethical decision). Students were requested to indicate (1) how ethical/unethical they believed the actions described were and (2) the probability that they would take the same action as the actor. The results of the analysis indicate no significant differences in the responses of the students whenever the vignette describes a situation in which the accountant makes an ethical decision. However, significant differences were indicated in both decisions whenever the students were dealing with a vignette describing an accountant making an unethical decision

Novel technique for measuring dispersion and detuning of a UV written silica-on-silicon waveguide

We shall present a new method of measuring the dispersive properties of UV written waveguides in the silica-on-silicon platform used to fabricate planar Bragg gratings. The technique involves direct measurement of the modal refractive index of a waveguide produced in the material. The data obtained also provides additional information about the spectral range of Bragg grating inscription. This direct writing technique reported previously differs from fibre Bragg grating fabrication by the small spot size of the writing beam and permits detuning of the Bragg wavelength from 1250nm to 1625nm. The fabrication technique provides the exact period of the grating and thus interrogation of the gratings produces information on the effective index of the mode. A series of integrated gratings were fabricated in a direct UV written waveguide via the direct grating writing technique in order to measure the wavelength dependence of the refractive index of the material. The Sellmeier curve obtained is shown

Wave-Driven Mass Loss in the Last Year of Stellar Evolution: Setting the Stage for the Most Luminous Core-Collapse Supernovae

During the late stages of stellar evolution in massive stars (C fusion and later), the fusion luminosity in the core of the star exceeds the star's Eddington luminosity. This can drive vigorous convective motions which in turn excite internal gravity waves. The local wave energy flux excited by convection is itself well above Eddington during the last few years in the life of the star. We suggest that an interesting fraction of the energy in gravity waves can, in some cases, convert into sound waves as the gravity waves propagate (tunnel) towards the stellar surface. The subsequent dissipation of the sound waves can unbind up to several $M_\odot$ of the stellar envelope. This wave-driven mass loss can explain the existence of extremely large stellar mass loss rates just prior to core-collapse, which are inferred via circumstellar interaction in some core-collapse supernovae (e.g., SNe 2006gy and PTF 09uj, and even Type IIn supernovae more generally). An outstanding question is understanding what stellar parameters (mass, rotation, metallicity, age) are the most susceptible to wave-driven mass loss. This depends on the precise internal structure of massive stars and the power-spectrum of internal gravity waves excited by stellar convection.Comment: Version accepted to MNRA

Modelling and correcting for the impact of the gait cycle on touch screen typing accuracy

Walking and typing on a smartphone is an extremely common interaction. Previous research has shown that error rates are higher when walking than when stationary. In this paper we analyse the acceleration data logged in an experiment in which users typed whilst walking, and extract the gait phase angle. We find statistically significant relationships between tapping time, error rate and gait phase angle. We then use the gait phase as an additional input to an offset model, and show that this allows more accurate touch interaction for walking users than a model which considers only the recorded tap position

The New Non-Science of Politics: On Turns to History in Political Science

Religion and America’s politics of peoplehood

"During my first year of graduate school in 1975, Professor Harvey C. Mansfield led a discussion section for graduate students in a survey course on the history of political thought. There he argued that there was a “hole in the center of liberalism,” by which he meant that a political philosophy whose central tenet was to permit people maximum freedom to pursue self-defined ends did not contain and probably could not contain standards to guide the best uses of that freedom."(...

Early childhood portfolios as a tool for enhancing learning during the transition to school

From 2005-2008 Mangere Bridge Kindergarten in New Zealand carried out a Centre of Innovation research project exploring the transition between early childhood education and school. A flexible action research approach was used, with the three teacher researchers, supported by two university research associates, developing and researching a range of strategies for supporting children’s learning as the children and their families ‘crossed the border’ from early childhood education to school. Many of these initiatives involved working closely with teachers in the local school setting. This paper focuses on one aspect of the findings, the ways in which the early childhood portfolios could be used to enhance children’s learning during the transition to school. Portfolios were identified as a belonging and empowerment tool; a means for school teachers to access to children’s funds of knowledge; playing a role in constructing a positive self-image about learning; and as valuable literacy artefacts

Asking the experts : developing and validating parental diaries to assess children's minor injuries

The methodological issues involved in parental reporting of events in children's everyday lives are discussed with reference to the development and validation of an incident diary, collecting concurrent data on minor injuries in a community study of children under eight years old. Eighty-two mothers participated in a comparison over nine days of daily telephone interviews and structured incident diaries. Telephone methods resulted in more missing data, and participants in both groups expressed a preference for the diary method. This diary was then validated on a sample of 56 preschool and school-aged children by comparing injury recording by a research health visitor with that of their mothers. Each failed to report some injuries, but there was good agreement overall, and in descriptive data on injuries reported by both. Parental diaries have the potential to provide rich data, of acceptable validity, on minor events in everyday life
